First Drive: 2014 BMW i3
2014 BMW i3
"A Purer Than Ever Sort Of Driving Pleasure"
This all started back in 2007 when the megacity urbanization trend hit full stride and BMW began brainstorming the 2020 future of mobility. The product was thus originally called the BMW MegaCity vehicle. Then the 'i' division of BMW was officially born in 2011, and we have since been exposed to various "leaked" images and official prototype unveilings of both this i3 and the i8 eco sports car. The latter (called i12 in the halls of Munich) was originally called the Concept Vision Efficient Dynamics and presented as a diesel-hybrid.
The time is now upon us for the market launch of the plug-in i3 (called i01 internally). The wider motoring public already has its opinions and BMW is listening to all of them, so there's a bundle of nerves around these limited drives of the i3 for a select few members of the media, Autoblog included. We came to an airfield outside of Munich and were handed an i3 test car to drive around a set course filled with blue- and white-striped cones. BMW tech experts were everywhere and some of the discussions around the various technical displays even got a little heated.
After our vast amounts of coverage during the gestation period of this new i3, we are well aware of the vocal – or at least written – sentiment of doubt among many computer users and BMW faithful. Not that this undertow of nay doesn't have its place in BMW's execution of the deliberately gradual i3 information rollout, but Munich and Leipzig (where the production center for i is located) are almost exclusively focused on customers who are new to BMW. These customers lack preconceived notions of BMW as a performance brand, and also crave the latest and greenest expression of their environmental concerns, preferably in an insanely networked and connected premium package. BMW i representatives have announced publicly that interest in the i3 is huge among newbies. Could the i3 become the Toyota Prius Plug-in for the no-Toyota-thank-you crowd?
Steel adds up to make less than 10 percent of the i3. The rest of it is made from lightweight and incredibly strong CFRP (i.e. carbon fiber reinforced plastic) and exhaustively lightened and stiffened aluminum. Aside from these two dominant materials, the large dashboard substructure is made of magnesium and the supporting structure for the center console is fiberglass. The exterior of our test cars, meanwhile, were still sporting a token strip of camouflage around the beltline and the interior was cloaked in tailor-cut sheets of felt to leave some things to be discovered in all of their beauty at the official reveal, which happens later this month in New York City.
On our drive, we tried only the full-EV version of the i3, which will be the first one available to customers starting November of this year in Europe and then January 2014 in North America and elsewhere. There will also be a hybrid version with a 650cc two-cylinder engine from BMW Motorrad acting only as a range-doubling generator that will be the bigger seller, in part because of how it skirts the CARB HOV rules in California. This version launches two months after the EV trim at a modest price premium of around $2,000, so we are told.
While the circuit laid out for us this day threatened to be a reverse NASCAR experience with all right-hand turns, there were actually several points where evasive moves and slaloming were required in order not to kill cones. These dicier sections showed the i3's consummate maneuverability in tighter spots – it has a small, 32.3-foot turning circle – and its very light steering feel. Visibility from the driver's throne is basically from a command seating position and can be characterized as vast.
To get the show started, it's a typical foot-on-pedal-press-the-Start-button ritual, the result of which is the digital dash instrumentation and electrical power unit waking up. There is one tone from the sound system that indicates you have pressed the Start button, then another that signifies you are good to go. The i3's drive selector, which shockingly does not have a capitalized sub-brand name like EDriveTronic, is a rotating handle on a stalk that branches from the 2 o'clock position on the steering column. And then you just get going by pressing the amp pedal (i.e. throttle).
If you leave the mode button on the console in Comfort, you can get pretty dang quickly to 60 miles per hour. The quoted time is 7.0 seconds flat and the i3 feels every bit capable of this through its 1:10 single reduction gear supplied by BMW's transmission assembly facility in Dingolfing. The other two drive mode settings are Eco Pro and Eco Pro+, each providing more recharging to the lithium-ion battery assembly through forced resistance, while limiting top speed and climate control energy-scavenging. Each adds an additional 12 percent to the estimated EV range.
The test cars were fitted with skinny, rock-hard and low-rolling resistance 19-inch Bridgestone Ecopia tires, sized 155/70 R19. After just a single spirited lap of the set course in 93-mph v-max Comfort mode, it was clear that we were driving the i3 in a style for which it was never designed. If you try to make the i3 live up to the well-honed definition of "Ultimate Driving Machine," you are categorically missing the entire point of the i3. We can expect that character of the i8 and other future sportier products from BMW i, but items such as the i3 are all about heading down the road in premium-built style and comfort while minimizing your carbon footprint more than anyone else around you. And doing so with the latest high tech.
Still, by stressing this age-old tagline of promised dynamism for the i3, albeit with an intended newer meaning, BMW is doing the i3 a disservice. This push to validate the i3 as a real Bimmer misses the mark a touch, mainly because the i3 is good at so many other things, the things you would expect from a green-thinking EV or e-hybrid from a German engineering-focused company's fresh little brand. The i3 fits better with the tagline "Pure Driving Pleasure," or with the new generic umbrella, "Designed for Driving Pleasure."
After our first misguided lap where the i3's side-to-side dynamics left something to be desired but the straight-line speed was really enjoyable, we played with the Eco Pro and Eco Pro+ modes. We also kept our weight transfers more sweeping and gradual as an everyday driver of the i3 will do. Keeping it real this way revealed the i3's truer driving pleasure, while also keeping things far greener and closer to the EV version's potential 124 miles per full charge in Eco Pro+ mode. These more efficient modes can be overridden by standing on the accelerator.
The e-motor mounted at the rear and to the left above the driven axle is a 168-horsepower unit from Bosch. Capable of 11,400 rpm, it's supplied 22 kWh of propulsive energy by the 507-pound lithium-ion battery pallet lying within the sturdy aluminum undercarriage. Torque from a standstill is 184 pound-feet if you stomp it, enough to fling the 2,755-pound i3 down the road with authority. While thus stomped – for instance during that first over-amped lap – there is a distinct sort of brisk rhythmical whipping-through-air sound coming from beneath the car, a sound that every single BMW i expert present insisted was news to them.
All of the needed connectivity iMobility apps via Smartphones are present, as are plans for i3 subscription fleets in key cities. The wall box quick chargers are a separately sold item, the price of which has yet to be determined, as has the price of having said box mounted properly in your garage. A battery charge up to 80 percent capacity with a standard European household DC plug will take roughly eight hours, while the same with the wall box (7.3 kW) will need three and a half to four hours. Find a serious 15-kW public charging station and it is all done in one hour. The warranty on the battery pack lasts for eight years.
The only distinct criticism we have regarding the i3 thus far – apart from the diminished dynamic and ride expectations that go part and parcel with any non-sporting EV – is its comparatively large front doors. There are no middle cabin pillars due to the incredible structural strength of the passenger cell, and the doors open carriage style to ease getting in and out. Closing the smaller rear doors is fine, but when we closed the front doors there was a serious amount of cheap-sounding and plastic-like rattles going on that was very un-BMW and un-premium. This worries us; while we love the fit and finish and bold idea of the i3, this new wee wondercar had better at least come across as absolutely premium and solid-sounding. As far as this early drive opportunity of admittedly pre-production cars goes, these frequently touched and used doors fail the basic requirement of a BMW experience.
We still like the i3 statement rolling along the road since it gets one and all wondering what that slick-finished car is, which is half the battle for this all-new i division in the coming years. If BMW i can keep the starting price at around $34,500 as recently announced, and if they can fix the front doors, that'll put the small people mover in good stead.

BMW i3 to start at $41,350*
BMW i3 to start at $41,350*
BMW i3 Pricing Announced.
US Manufacturer's Suggested Retail Price just $41,350
The Ultimate Driving Machine® in a new era of sustainability
Woodcliff Lake, NJ – 3:00 am EDT/12:00 am PDT July 22, 2013... BMW today announced pricing for the ground-breaking BMW i3 electric vehicle. The Manufacturer's Suggested Retail Price (without Destination & Handling) in the US will be $41,350, before any federal or state incentives. The Destination & Handling fee in the US is currently $925.
"The BMW i3 heralds the dawn of a new era for individual mobility and for the BMW Group. True to a genuine BMW, the BMW i3 has strong emotional appeal, outstanding product substance and a guarantee of sheer driving pleasure," said Ian Robertson, Member of the Board of Management, Sales and Marketing BMW. "With this leading-edge vehicle and attractive price, we will provide customers with a compelling offer for electromobility."
The BMW i3's 170 horsepower and 184 lb-ft of torque hybrid-synchronous electric motor, developed and produced by BMW, is electrified by a 22-kWh lithium-ion battery, good for 80-100 miles of emission-free driving. Designed from the ground up to be an electric car, the BMW i3 uses the Industry's first mass produced carbon fiber reinforced plastic (CFRP) passenger cell mounted on an aluminum chassis.
The BMW i3 will offer interior space comparable to the legendary BMW 3 Series on a shorter overall body. Its 32.3-foot turning circle and a relatively long wheelbase make it agile and engaging to drive, yet ideally suited to driving in dense urban areas.
Quick and convenient charging is possible either with the home charging station supplied by BMW i or at any public charging station that uses a Level 2 SAE J1772 charging system. DC fast charging, using the SAE DC Combo-Fast Charger, will be available as an option. From a public fast-charging station, it will provide an 80 percent charge from a fully depleted battery in just 20 minutes.
BMW i's commitment to sustainable urban mobility encompasses the i3 production facilities, where hydro-electric, wind and solar power are used to power the CFRP production facilities in Moses Lake, Washington and the Leipzig, Germany assembly line. Sustainable materials are also used for the BMW i3 interior upholstery and trim.
The BMW i3 will make its world debut at three simultaneous events in New York, London and Beijing on Monday, July 29. It will arrive in US showrooms in the second quarter of 2014.

Even though we recently drove a near-production version of the BMW i3, the car still wore light exterior and interior camouflage. Today, BMW took off that little bit of camo and made a big announcement: The i3 will go on sale in the US for $41,350 in the second quarter of 2014. That does not include any state or federal incentives that could lower the price or the $925 destination fee. The i3 will debut with three trim levels, which BMW is referring to as Worlds: Mega (standard in the US), Giga and Tera.
The BMW i3 is chock-full of new technology afforded by its design as an EV from the start of development, which has resulted in a vehicle layout unique to the i3. BMW has named it LifeDrive architecture, and it features the Life Module and the Drive Module. The Life Module is the i3's pillar-less passenger cell, which is the first mass-produced monocoque made of carbon fiber reinforced plastic (CFRP). The tougher-than-steel material is also 30-percent lighter than aluminum, which contributes to the i3's relatively light weight of 2,700 pounds (preliminary US figure) and, in turn, increases its energy efficiency. Expect more of this technology to find its way into future BMWs.
The Drive Module, a 100-percent aluminum chassis mounted under the Life Module, houses everything that makes the i3 go. It includes the 22-kilowatt, 450-pound lithium ion battery mounted as centrally as possible, and provides power to a rear-mounted electric motor that turns the rear wheels. With 170 horsepower and 184 pound-feet of torque from zero rpm, the single-gear i3 can accelerate from 0-30 miles per hour in 3.5 seconds and 0-60 mph in about 7.0 seconds, but it has a top speed of only 93 mph. BMW says the i3 has a real-world EV range of 80-100 miles, and the standard charger can fill the battery in three hours. Opt for the SAE DC Combo Fast Charger and 30 minutes is all it takes for a full charge; 20 minutes will bump the battery to 80 percent. For customers who have range anxiety, BMW gives them the option to install a 34-hp, 650cc two-cylinder generator as a range extender for the electric drive system.
Worldwide debut of the all-new BMW i3.
The Ultimate Driving Machine in a new era of Individual Urban Mobility
Woodcliff Lake, N.J. – BMW today introduced the all-new BMW i3 electric car, constructed in a revolutionary way from next-generation materials. The BMW i3 will go on sale in the US market in the second quarter of 2014, and starts with a base MSRP of $41,350, before any federal or state incentives, and before Destination & Handling fee (currently $925).

1. Highlights: The All-New BMW i3:
The new all-electric BMW i3 is a landmark in BMW's mission to provide a completely sustainable, electric vehicle that still stays true to the Ultimate Driving Machine moniker. The BMW i3 is the first product of the new BMW i sub-brand, and is a truly purpose built electric car. It's a new era for electro mobility at BMW.
The vehicle concept behind the BMW i3 was designed from the outset to incorporate an all-electric drive system. This has numerous advantages over "conversion" vehicles, in which the original combustion engine is swapped for an electric motor. The engineers can design whatever works best, in terms of construction, dimensions and configuration of the electric drive system's components. The car's development is dictated by the characteristics designed into the car by the development team and not by the constraints imposed by a pre-existing vehicle design. For example, the space in a conversion vehicle set aside for the fuel tank or exhaust system cannot be used. In the BMW i3 there is no need for this kind of compromise.
This leads to the LifeDrive architecture concept, which was purpose-built specifically for the BMW i3. It is comprised of two modules; the Life Module, and the Drive Module. Think of the Life Module as the passenger cabin, or greenhouse. It is the first-ever mass produced Carbon Fiber Reinforced Plastic (CFRP) passenger cell in the automotive business, and is a big factor in the cars efficiency. Carbon Fiber Reinforced Plastic is equally as strong as steel, while being 50% lighter, and 30% lighter than aluminum. The result is an electric car that weighs about 2,700 lbs (preliminary US figures).
Due to the lightweight, high tensile strength of CFRP, the passenger cell has added protection, and the battery has less work to do, which allows for the use of a smaller, lighter battery that saves even more weight, reduces charging time and increases range. The light weight design of the Life Module also lowers the BMW i3's center of gravity, making it a more engaging and dynamic car to drive.
The Drive Module, which is constructed out of 100% aluminum, consists of the 22-kWh, 450 lb. lithium-ion battery, electric drive train, MacPherson strut and 5-link rear suspension system and structural and crash components. The battery mounted in the rear, close to the drive wheels, gives impressive performance characteristics while also providing better traction.
Another benefit of the LifeDrive architecture concept is that there is no space-consuming transmission tunnel running through the center of the car, like in most internal combustion powered cars, because of the separate Drive Module. This gives the BMW i3 the interior space of the BMW 3 Series, while only having the footprint of the much smaller BMW 1 Series.
Even the vehicle's key is sustainably manufactured. The source material of the new bio-polymer key is based on castor oil pressed from castor seeds. The owner's manual is also made from renewable resources.
The interior is made using high quality renewable sources and recycled materials. The BMW i3 has the Next Premium interior, which blends sustainable resources with a premium feel for the same interior quality as the BMW 5 Series Sedan. 25% of the plastics in the interior and 25% of the thermoplastic parts on the exterior are made from either recycled materials or renewable sources.
According to studies carried out as part of BMW's Project i, involving more than 1,000 participants and conducted over some 12.5 million miles, it was revealed that the average daily distance covered was around 30 miles. The BMW i3 will be able to travel 80 to 100 miles on a single charge. This can be increased by up to approximately 12% in ECO PRO mode and by the same amount again in ECO PRO+ mode. It is able to recharge in only 3 hours with the use of a 220V Level 2, 32-amp J1772 charger. The SAE DC Combo Fast Charging, which charges the BMW i3 up to 80% in 20 minutes, and 100% in 30, can be had as an option.
In order to reduce range anxiety, a rear-mounted 650cc, 34 hp, two-cylinder, gasoline-powered Range Extender generator is available, which roughly doubles the vehicle's range. When the battery gets to a certain level, the Range Extender starts and maintains the battery's current state of charge. The Range Extender never directly drives the vehicle's wheels. The Range Extender adds roughly 330 lbs. to the vehicle curb weight and has a fuel capacity of 2.4 gallons.
Since 1999 according to the DOE, average gasoline prices in America have increased from approximately $1.136 to $3.618, or about a 218%. In the same time, the pricing of electricity has increased from 6.6 cents to 9.9 cents, a change of only 50%, making electricity a far more attractive commodity from a pricing standpoint.

2. The Ultimate Drive Machine®.
BMW makes the Ultimate Driving Machine, and that holds true for the BMW i3. The hybrid synchronous electric motor, which weighs only 110 lbs., is developed and produced specially by the BMW Group for use in the BMW i3, with maximum revs of 11,400 rpm, generates an output of 170 hp and outputs maximum torque of 184 lb-ft on tap from the moment the car pulls away. That's propels the 2,700 lb car from 0-30mph in 3.5 seconds, 0-60mph in approximately 7.2 seconds, and to an electronically limited top speed of 93 mph (preliminary USA figures). Much like engine braking with a manual transmission, but even more effective, the accelerator pedal also acts as a brake when the driver lifts off the accelerator.
The BMW i3 features Brake Energy Regeneration, which, when the driver lifts off, the motor acts as a generator and converts the kinetic energy into electricity, which is fed back into the battery for a range gain. This Regeneration is speed-sensitive, which means that the car "coasts" for added efficiency at high speeds, and generates the strong braking effect at lower speeds.
The BMW i3's accelerator pedal has a distinct "neutral" position. Rather than switching straight to energy Regeneration when the driver eases off the accelerator, the electric motor uses zero torque control to separate from the drivetrain and deploy only the available kinetic energy for propulsion. In this mode, the BMW i3 cruises using virtually no energy at all. This is another way anticipatory driving can preserve energy and increase the car's range.
The impressive electric motor, small turning circle of 32.3 feet, – a major benefit to driving in the city – BMW's near-perfect 50-50 weight distribution, precise electric power steering and the stable suspension set-up help to make the i3 as satisfying to drive as every other BMW.
The BMW i3's tires are a unique 155/70/19 size on 19-inch light-alloy wheels, but the contact patch is the same of that of a more conventional 16-inch tire. To improve efficiency, they have low rolling resistance, and the narrow section width is a key factor in the BMW i3's super-tight turning radius.
The BMW i3 uses the BMW eDrive rear-wheel drive powertrain previously found on the BMW ActiveE. eDrive offers driving dynamics worthy of the Ultimate Driving Machine name and offers zero tailpipe emission driving. Beyond the traditional immediacy of response offered by electric motors when pulling away, power development in the BMW i3 also remains unbroken through higher speeds. Power is sent to the rear wheels through a single-speed transmission, allowing the BMW i3 to accelerate with an uninterrupted flow of power up to its top speed.
3. City Friendly: The Future of Urban Mobility.
The BMW i3 marks the introduction of a new type of megacity vehicle. Its small size allows it to easily maneuver and park on city streets, while the car's short front and rear overhangs make parking in tight spaces much easier. Its sharp turning radius and nimble handling are the perfect match for city driving. In the front, the Slide Through Experience allows the driver to slide through the car and exit on the passenger side, to avoid exiting into a busy city street. This is made possible because of the absence of the transmission tunnel. The coach doors make getting into and out of the car much more practical by eliminating the B pillar and creating one large opening to enter and exit.
Not having to fill up on gas is a big advantage while living in the city due to the lack of gas stations. Since electricity is so readily available, recharging is possible almost anywhere, and practically gives the BMW i3 unlimited range due to being able to charge at any and every stop.
Emission-free driving is also a plus in the city. Cities are so congested with cars idling at red lights or stop and go traffic, so having a car that runs on electricity that doesn't pollute is another way that the BMW i3 benefits the environment, and its owner.
On a similar note, the navigation system can take traffic conditions into consideration and help route around any areas of large congestion, which is a huge benefit when living in a city with a lot of traffic. It can help maximize efficiency and cut down commute times in order to save you time.
The same navigation system also remembers the owners driving style and can judge by that and the amount of charge left if a route is too long or if a recharge is necessary for the return journey.
4. Design: Aesthetic Appeal with Elegant, Renewable Interior.
The BMW i3 is stretching the definitive envelope of what a conventional car can be and how it should look. Its striking appearance is unique to the BMW i sub-brand while still remaining unmistakably a BMW.
Black Band.
The front end has a clear and simple design. BMW's iconic kidney grilles headlines the front end with the BMW i blue background. Under the kidney grille, silver layers sculpt the front apron. Contrasting black surfaces identify the functional load compartment under the hood and air inlets. Aerodynamic Air Curtains give an aggressive appearance to the BMW i3, while also helping to increase the range by minimizing air resistance and drag. U-shaped, LED headlights, give a fresh take on the BMW light design and give the car character.
At the rear end, the large rear window gives great visibility and easy access to the trunk. The roof lines are optimized to give as much interior space as possible. The LED U-shaped taillights are housed in the rear window and appear to be floating there.
Stream flow.
The rear diffuser is the lowest point on the car and lends to its aerodynamics. Outlined in blue (not available with Solar Orange Metallic exterior color), the diffuser is shaped to show the BMW i3's powerful stance.
Thanks to its LifeDrive architecture, the BMW i3 is a new canvas for BMW interior designers. There is no center tunnel taking up space, which creates an open, roomy cabin. The front and rear bench seats allow for easy movement inside the vehicle and even allow the driver to exit through the passenger door if necessary.
All driving controls are ergonomically placed for easy access to the driver. The instrument panel stretches through the whole interior from the air vents next to the steering wheel to just before the passenger door. It encompasses the radio and climate controls as well. The freestanding steering column is a distinctive element in the light interior. All of the driving controls, such as the instrument cluster, start/stop button and gear shift selector can be found there.
The interior, which is put together using a technique known as layering, – which is the utilization of space through the structuring of lines and surfaces into layers – features Next Premium. It is made of high quality renewable raw materials, in the name of sustainability. The driver's seat is located in a semi-command driving position, set-up higher for a better view of the road. Certain parts of the instrument panel and door panels are made using southern Asia's Kenaf plant natural fibers to save about 10% weight, while the interior leather is tanned using a natural process that uses olive leaf extract to provide protection against fading and wear while giving a unique look.
Using a magnesium supporting structure for the instrument panel saves weight in two ways. Superior material attributes over conventional sheet steel results in a weight reduction of 20%. Also, the high composite rigidity of the magnesium supporting structure allows a reduction in components and lowers weight by a further 10%.
The wood trim used in the dashboard is crafted from eucalyptus which is grown in Europe and certified as 100% sourced from responsible forestry. As the eucalyptus ages, it darkens and changes color. The location of the crafting was selected carefully to ensure short delivery routes to the production stages.
The Carbon Fiber Reinforced Plastic (CFRP), which is produced near Moses Lake, Washington, is made primarily with the use of hydroelectric power, harvested nearby. This is done to minimize the effect that BMW i3 production has on the environment. Since more than 10% of the carbon fiber needed to manufacture the BMW i3 is made from recycled materials, it is another way the BMW i3 is completely sustainable. The roof is made of CFRP scraps to help recycle left over material from other parts.
5. Explore the World: Vehicle Trim Levels.
Due to the unfamiliarity of electric mobility technology in the United States, buying an EV can be a daunting experience for the average customer. BMW sought to make this process as simple as possible in the new BMW i3. The BMW i3 comes in three different worlds: Mega, Giga and Tera, all of which come equipped with a very high level of standard equipment.
The base Mega World comes standard with 19-inch extra-efficient forged aluminum wheels, BMW Navigation, BMW ConnectedDrive with eCall, the BMW i Remote, an alarm, 7.4 kW on board charger and LED headlights, DRLs and tail lights.

6. BMW ConnectedDrive. Mobility services and new driver assistance systems.
BMW ConnectedDrive is the interface between the customer, their car, 360 Electric, and the Premium Mobility Service. Connected mobility is the embodiment of an individual, sustainable, efficient and convenient form of urban mobility. It is a crucial part of the BMW i and urban lifestyle.
An embedded SIM card in the BMW i3 is the key that unlocks the BMW ConnectedDrive services, available to the new electric model. A feature of BMW ConnectedDrive is BMW i Navigation, which can search for a nearby charging station, which should give the driver piece of mind, knowing that there is a station nearby. It can also give a real world range estimate and visualization of the estimate with the SpiderMap, Real Time Traffic Information and plan a route that avoids the traffic as best as possible.
The customer has access to personal assistance from a BMW ConnectedDrive agent at any time of the day or night. Concierge Service can help answer almost any of the driver's questions. They can recommend restaurants, give information on destinations or guide the driver to the nearest charging station, among other things.
In the unfortunate situation when an accident occurs, Intelligent Emergency Call ("eCall") sends information like location, number of front-seat occupants, and even crash severity data to the BMW ConnectedDrive Call Center, which quickly informs the appropriate 911-dispatch center.
BMW ConnectedDrive can also connect directly with your iPhone with an original Apple cable that connects to the car and built-in BMW Apps.
The optionally available Driving Assistant Plus for the BMW i3 comprises Collision Warning with brake priming function, which is activated at speeds up to about 35 mph (60 km/h) and is able to respond to both moving and stationary vehicles ahead, as well as to pedestrians. It also comes with Active Cruise Control including Stop & Go function. In addition to visual and audible warnings, the system is capable of braking the vehicle by itself, if required, with up to maximum stopping power. The Parking Assistant can also be found on the option list and performs the steering maneuvers at the same time as controlling accelerator, brake and gear selection, enabling fully automated parallel parking. Another handy optional extra is the Traffic Jam Assistant that allows drivers to delegate the tasks of pulling away, braking and steering to keep the vehicle in lane. Meanwhile, the Speed Limit Info system is also offered.
7. 360 Electric: Support and Convenience for Electric Mobility.
Electric cars differ drastically from their gas-powered counterparts, and the 360 Electric features further that differential. All of the 360 Electric features help to ensure convenient electro mobility in most situations.
If the BMW i3 buyer has a private parking space at their home, BMW i will offer a home charging station, which includes a BMW i charging station for convenient charging. They will even send a representative to install it to any specific need. 360 Electric will also help with public charging by locating the nearest station.
As part of 360 Electric, the BMW i Remote app links to your car and can monitor its battery level, charging status and other charging-related functions, such as heating and air conditioning. The app can also give the cars location, lock or unlock the doors, honk the horn, or flash the lights.
Before driving away in the BMW i3, it is recommended to precondition that battery to the preferred operating temperature of between 60 - 70 degrees Fahrenheit to optimize range. Battery temperature may be monitored through the iDrive system. The battery liquid cooling system keeps the battery at the ideal operating temperature which increases performance and life expectancy. Battery condition is controlled and operated in harmony by the intelligent energy management system. This, combined with Brake Energy Regeneration system extends the vehicle's range while enhancing its performance.
The Range Assistant is engaged both for route planning and during journeys already under way. Topographical mapping technology helps find the most efficient route to your destination by calculating distance, elevation and other factors, in order to get the best range from your BMW i3. If the destination is beyond the cars range, it can suggest switching to ECO PRO or ECO PRO+ to get more from the battery's charge.
In the unlikely circumstance of a breakdown, the BMW Assist Safety Plan provides contact with a Response Specialist at the touch of a button.
BMW Assist also introduces Navigation services specially-developed to enhance electric mobility alongside familiar features including the Concierge Services information facility and the intelligent BMW Assist eCall. Moreover, drivers may use the BMW i Remote app to share information with their car using a smartphone. The pedestrian navigation function guides the driver from parking place to their final destination and back.
8. Safety: Always a true BMW.
From an efficiency standpoint, the body of the BMW i3 needs to be not only strong but, above all, light. However, from a safety point of view, it has to be not only light but, above all, strong. This apparent conflict of interests highlights the engineers' pioneering work in developing the vehicle architecture of the BMW i3. Here, there is no contradiction between lightweight construction and safety. Quite the opposite, in fact: the LifeDrive concept of the BMW i3, with its combination of aluminum and carbon-fiber-reinforced plastic (CFRP), is on a par with other structures and even performs better in some areas of crash testing despite its lightweight design. The use of CFRP essentially allows the construction of extremely lightweight bodies. Moreover, CFRP possesses an impressive ability to absorb energy and is extremely damage-tolerant. CFRP is the lightest material that can be used in the construction of car bodies without compromising on safety.
The LifeDrive concept is based around two horizontally separate independent modules. The Drive module – the aluminum chassis – gives the car its high-strength foundations and integrates the battery and drive system into a single structure. The Life module, meanwhile, consists principally of a high-strength and extremely lightweight passenger compartment made from CFRP. With this innovative concept, the BMW Group takes the combination of lightweight design, vehicle architecture and crash safety to an entirely new dimension.
LifeDrive module offers tremendous safety.
The crash requirements in automotive manufacture are very strict. Numerous impact criteria stipulated by the stringent guidelines of global consumer protection organizations and legislators have to be taken into account. During the development of the BMW i3 concept, there was close consultation with the international crash test institutes on the innovative car body and safety concept of the BMW i models.
The high-strength passenger compartment teams up with the intelligent distribution of forces within the LifeDrive module to provide the cornerstones for optimum occupant protection. Even after the structurally-debilitating offset front crash at 64 km/h (40 mph), the extremely rigid material maintains an intact survival space for passengers. The crash-activated aluminum structures at the front and rear end of the Drive module provide additional safety, so that less body deformation occurs compared with comparable steel bodies. Furthermore, the "cocoon effect" of the CFRP car body ensures that the doors can be opened without any problem and the interior remains largely free of any intrusions.
Even rescue scenarios have been worked through and checked. In standard cutting tests, the process of rescuing occupants from a BMW i3 involved in an accident was comparable to that for a conventional vehicle. In some respects, indeed, it was more straightforward since the lighter components can be more easily cut than high-strength steels, for example.
Impressive rigidity, combined with its ability to absorb an enormous amount of energy, makes CFRP extremely damage-tolerant. Even at high impact speeds it displays barely any deformation. As in a Formula One cockpit, this exceptionally stiff material provides an extremely strong survival space. Furthermore, the body remains intact in a front or rear-on impact, and the doors still open without a problem after a crash.
In its dry, resin-free state CFRP can be worked almost like a textile, and as such allows a high degree of flexibility in how it is shaped. The composite only gains its rigid, final form after the resin injected into the lattice has hardened. This makes it at least as durable as steel, but it is much more lightweight.
The high tear resistance along the length of the fibers also allows CFRP components to be given a high-strength design by following their direction of loading. To this end, the fibers are arranged within the component according to their load characteristics. By overlaying the fiber alignment, components can also be strengthened against load in several different directions. In this way, the components can be given a significantly more efficient and effective design than is possible with any other material that is equally durable in all directions – such as metal. This, in turn, allows further reductions in terms of both material use and weight, leading to another new wave of savings potential. The lower accelerated mass in the event of a crash means that energy-absorbing structures can be scaled back, cutting the weight of the vehicle.
Superior protection in a side impact.
The ability of CFRP to absorb energy is truly extraordinary. Pole impacts and side-on collisions both highlight the impressive safety-enhancing properties of CFRP. Despite the heavy, in some cases concentrated forces, the material barely sustains a dent, and passengers enjoy nearly unbeatable protection. All of which makes CFRP perfectly suited for use in a vehicle's flanks, where every centimeter of undamaged interior is invaluable. However, there are limits to what CFRP can endure. If the forces applied go beyond the limits of the material's strength, the composite of fibers breaks up into its individual components in a controlled process.
In the Euro NCAP side impact test, in which a pole strikes the side of the vehicle dead-center at 32 km/h (20 mph), the carbon fiber composite also demonstrates its extraordinary energy-absorbing capacity. The Life module absorbs the entire impact with minimal deformation, guaranteeing optimum passenger protection. Even as CFRP dissipates energy, danger to passengers or other road users is substantially mitigated.
The best of both worlds: combining aluminum and CFRP.
The new Drive module has also been carefully designed and structured with these exacting crash requirements in mind. Crash-active aluminum structures in the front and rear sections of the vehicle provide additional safety. In a front or rear-on collision, these absorb a large proportion of the energy generated. The battery, meanwhile, is mounted in the underbody section of the car to give it the best possible degree of protection. Statistically, this is the area that absorbs the least energy in the event of a crash, and the vehicle shows barely any deformation here as a result. Moreover, positioning the battery in the underbody allows the BMW Group development engineers to give the vehicle an ideal low center of gravity, which makes it extremely agile and unlikely to roll over.
The high-voltage battery also benefits from the excellent deformation properties of the CFRP Life module. In the side crash test, the pole does not penetrate as far as the battery. The mix of materials used and the intelligent power distribution in the LifeDrive module ensure that the high-voltage battery is optimally protected even in the side sill area.
All in all, the high-strength CFRP passenger cell teams up with the intelligent distribution of forces in the LifeDrive module to lay the foundations for optimum occupant protection.
Post-crash notification.
In the unfortunate situation when an accident occurs, Intelligent Emergency Call ("eCall") sends information like location, number of front-seat occupants, and even crash severity data to the BMW ConnectedDrive Call Center, which quickly informs the appropriate 911-dispatch center.
Lithium-ion batteries are safe even in the event of a fire.
Safety is a key criterion in the development of the BMW i models. A range of systems and measures have been implemented in the vehicle that ensure safety in normal operation and in the event of accidental fires. The high-voltage system is designed to cope with accidents beyond the legal requirements, with the high-voltage battery including features that ensure its safe reaction even in situations such as this.
The latest series of tests conducted by the renowned DEKRA E-Mobility Competence Center were extremely extensive – ranging from how a car might catch fire, how the flames might spread and what would be required to extinguish the fire, to the pollution caused by run-off of the water used for fighting the fire. The experts concluded that electric and hybrid cars with lithium-ion drive system batteries are at least as safe as vehicles with conventional drive systems in the event of fire.
To ensure maximum safety in such a crash scenario, the high-voltage battery is disconnected from the high-voltage system and the connected components discharged when the passenger restraint systems are triggered. This safely prevents the possibility of a short circuit, which could lead to electric shocks or cause a fire.
The Ultimate Driving Machine in a new era of Individual Urban Mobility
Woodcliff Lake, N.J. – BMW today introduced the all-new BMW i3 electric car, constructed in a revolutionary way from next-generation materials. The BMW i3 will go on sale in the US market in the second quarter of 2014, and starts with a base MSRP of $41,350, before any federal or state incentives, and before Destination & Handling fee (currently $925).

8. Safety: Always a true BMW.
1. Highlights: The All-New BMW i3:
The new all-electric BMW i3 is a landmark in BMW's mission to provide a completely sustainable, electric vehicle that still stays true to the Ultimate Driving Machine moniker. The BMW i3 is the first product of the new BMW i sub-brand, and is a truly purpose built electric car. It's a new era for electro mobility at BMW.
The vehicle concept behind the BMW i3 was designed from the outset to incorporate an all-electric drive system. This has numerous advantages over "conversion" vehicles, in which the original combustion engine is swapped for an electric motor. The engineers can design whatever works best, in terms of construction, dimensions and configuration of the electric drive system's components. The car's development is dictated by the characteristics designed into the car by the development team and not by the constraints imposed by a pre-existing vehicle design. For example, the space in a conversion vehicle set aside for the fuel tank or exhaust system cannot be used. In the BMW i3 there is no need for this kind of compromise.
This leads to the LifeDrive architecture concept, which was purpose-built specifically for the BMW i3. It is comprised of two modules; the Life Module, and the Drive Module. Think of the Life Module as the passenger cabin, or greenhouse. It is the first-ever mass produced Carbon Fiber Reinforced Plastic (CFRP) passenger cell in the automotive business, and is a big factor in the cars efficiency. Carbon Fiber Reinforced Plastic is equally as strong as steel, while being 50% lighter, and 30% lighter than aluminum. The result is an electric car that weighs about 2,700 lbs (preliminary US figures).
Due to the lightweight, high tensile strength of CFRP, the passenger cell has added protection, and the battery has less work to do, which allows for the use of a smaller, lighter battery that saves even more weight, reduces charging time and increases range. The light weight design of the Life Module also lowers the BMW i3's center of gravity, making it a more engaging and dynamic car to drive.
The Drive Module, which is constructed out of 100% aluminum, consists of the 22-kWh, 450 lb. lithium-ion battery, electric drive train, MacPherson strut and 5-link rear suspension system and structural and crash components. The battery mounted in the rear, close to the drive wheels, gives impressive performance characteristics while also providing better traction.
Another benefit of the LifeDrive architecture concept is that there is no space-consuming transmission tunnel running through the center of the car, like in most internal combustion powered cars, because of the separate Drive Module. This gives the BMW i3 the interior space of the BMW 3 Series, while only having the footprint of the much smaller BMW 1 Series.
Even the vehicle's key is sustainably manufactured. The source material of the new bio-polymer key is based on castor oil pressed from castor seeds. The owner's manual is also made from renewable resources.
The interior is made using high quality renewable sources and recycled materials. The BMW i3 has the Next Premium interior, which blends sustainable resources with a premium feel for the same interior quality as the BMW 5 Series Sedan. 25% of the plastics in the interior and 25% of the thermoplastic parts on the exterior are made from either recycled materials or renewable sources.
According to studies carried out as part of BMW's Project i, involving more than 1,000 participants and conducted over some 12.5 million miles, it was revealed that the average daily distance covered was around 30 miles. The BMW i3 will be able to travel 80 to 100 miles on a single charge. This can be increased by up to approximately 12% in ECO PRO mode and by the same amount again in ECO PRO+ mode. It is able to recharge in only 3 hours with the use of a 220V Level 2, 32-amp J1772 charger. The SAE DC Combo Fast Charging, which charges the BMW i3 up to 80% in 20 minutes, and 100% in 30, can be had as an option.
In order to reduce range anxiety, a rear-mounted 650cc, 34 hp, two-cylinder, gasoline-powered Range Extender generator is available, which roughly doubles the vehicle's range. When the battery gets to a certain level, the Range Extender starts and maintains the battery's current state of charge. The Range Extender never directly drives the vehicle's wheels. The Range Extender adds roughly 330 lbs. to the vehicle curb weight and has a fuel capacity of 2.4 gallons.
Since 1999 according to the DOE, average gasoline prices in America have increased from approximately $1.136 to $3.618, or about a 218%. In the same time, the pricing of electricity has increased from 6.6 cents to 9.9 cents, a change of only 50%, making electricity a far more attractive commodity from a pricing standpoint.

2. The Ultimate Drive Machine®.
BMW makes the Ultimate Driving Machine, and that holds true for the BMW i3. The hybrid synchronous electric motor, which weighs only 110 lbs., is developed and produced specially by the BMW Group for use in the BMW i3, with maximum revs of 11,400 rpm, generates an output of 170 hp and outputs maximum torque of 184 lb-ft on tap from the moment the car pulls away. That's propels the 2,700 lb car from 0-30mph in 3.5 seconds, 0-60mph in approximately 7.2 seconds, and to an electronically limited top speed of 93 mph (preliminary USA figures). Much like engine braking with a manual transmission, but even more effective, the accelerator pedal also acts as a brake when the driver lifts off the accelerator.
The BMW i3 features Brake Energy Regeneration, which, when the driver lifts off, the motor acts as a generator and converts the kinetic energy into electricity, which is fed back into the battery for a range gain. This Regeneration is speed-sensitive, which means that the car "coasts" for added efficiency at high speeds, and generates the strong braking effect at lower speeds.
The BMW i3's accelerator pedal has a distinct "neutral" position. Rather than switching straight to energy Regeneration when the driver eases off the accelerator, the electric motor uses zero torque control to separate from the drivetrain and deploy only the available kinetic energy for propulsion. In this mode, the BMW i3 cruises using virtually no energy at all. This is another way anticipatory driving can preserve energy and increase the car's range.
The impressive electric motor, small turning circle of 32.3 feet, – a major benefit to driving in the city – BMW's near-perfect 50-50 weight distribution, precise electric power steering and the stable suspension set-up help to make the i3 as satisfying to drive as every other BMW.
The BMW i3's tires are a unique 155/70/19 size on 19-inch light-alloy wheels, but the contact patch is the same of that of a more conventional 16-inch tire. To improve efficiency, they have low rolling resistance, and the narrow section width is a key factor in the BMW i3's super-tight turning radius.
The BMW i3 uses the BMW eDrive rear-wheel drive powertrain previously found on the BMW ActiveE. eDrive offers driving dynamics worthy of the Ultimate Driving Machine name and offers zero tailpipe emission driving. Beyond the traditional immediacy of response offered by electric motors when pulling away, power development in the BMW i3 also remains unbroken through higher speeds. Power is sent to the rear wheels through a single-speed transmission, allowing the BMW i3 to accelerate with an uninterrupted flow of power up to its top speed.
3. City Friendly: The Future of Urban Mobility.
The BMW i3 marks the introduction of a new type of megacity vehicle. Its small size allows it to easily maneuver and park on city streets, while the car's short front and rear overhangs make parking in tight spaces much easier. Its sharp turning radius and nimble handling are the perfect match for city driving. In the front, the Slide Through Experience allows the driver to slide through the car and exit on the passenger side, to avoid exiting into a busy city street. This is made possible because of the absence of the transmission tunnel. The coach doors make getting into and out of the car much more practical by eliminating the B pillar and creating one large opening to enter and exit.
Not having to fill up on gas is a big advantage while living in the city due to the lack of gas stations. Since electricity is so readily available, recharging is possible almost anywhere, and practically gives the BMW i3 unlimited range due to being able to charge at any and every stop.
Emission-free driving is also a plus in the city. Cities are so congested with cars idling at red lights or stop and go traffic, so having a car that runs on electricity that doesn't pollute is another way that the BMW i3 benefits the environment, and its owner.
On a similar note, the navigation system can take traffic conditions into consideration and help route around any areas of large congestion, which is a huge benefit when living in a city with a lot of traffic. It can help maximize efficiency and cut down commute times in order to save you time.
The same navigation system also remembers the owners driving style and can judge by that and the amount of charge left if a route is too long or if a recharge is necessary for the return journey.
4. Design: Aesthetic Appeal with Elegant, Renewable Interior.
The BMW i3 is stretching the definitive envelope of what a conventional car can be and how it should look. Its striking appearance is unique to the BMW i sub-brand while still remaining unmistakably a BMW.
Black Band.
The front end has a clear and simple design. BMW's iconic kidney grilles headlines the front end with the BMW i blue background. Under the kidney grille, silver layers sculpt the front apron. Contrasting black surfaces identify the functional load compartment under the hood and air inlets. Aerodynamic Air Curtains give an aggressive appearance to the BMW i3, while also helping to increase the range by minimizing air resistance and drag. U-shaped, LED headlights, give a fresh take on the BMW light design and give the car character.
At the rear end, the large rear window gives great visibility and easy access to the trunk. The roof lines are optimized to give as much interior space as possible. The LED U-shaped taillights are housed in the rear window and appear to be floating there.
Stream flow.
The rear diffuser is the lowest point on the car and lends to its aerodynamics. Outlined in blue (not available with Solar Orange Metallic exterior color), the diffuser is shaped to show the BMW i3's powerful stance.
Thanks to its LifeDrive architecture, the BMW i3 is a new canvas for BMW interior designers. There is no center tunnel taking up space, which creates an open, roomy cabin. The front and rear bench seats allow for easy movement inside the vehicle and even allow the driver to exit through the passenger door if necessary.
All driving controls are ergonomically placed for easy access to the driver. The instrument panel stretches through the whole interior from the air vents next to the steering wheel to just before the passenger door. It encompasses the radio and climate controls as well. The freestanding steering column is a distinctive element in the light interior. All of the driving controls, such as the instrument cluster, start/stop button and gear shift selector can be found there.
The interior, which is put together using a technique known as layering, – which is the utilization of space through the structuring of lines and surfaces into layers – features Next Premium. It is made of high quality renewable raw materials, in the name of sustainability. The driver's seat is located in a semi-command driving position, set-up higher for a better view of the road. Certain parts of the instrument panel and door panels are made using southern Asia's Kenaf plant natural fibers to save about 10% weight, while the interior leather is tanned using a natural process that uses olive leaf extract to provide protection against fading and wear while giving a unique look.
Using a magnesium supporting structure for the instrument panel saves weight in two ways. Superior material attributes over conventional sheet steel results in a weight reduction of 20%. Also, the high composite rigidity of the magnesium supporting structure allows a reduction in components and lowers weight by a further 10%.
The wood trim used in the dashboard is crafted from eucalyptus which is grown in Europe and certified as 100% sourced from responsible forestry. As the eucalyptus ages, it darkens and changes color. The location of the crafting was selected carefully to ensure short delivery routes to the production stages.
The Carbon Fiber Reinforced Plastic (CFRP), which is produced near Moses Lake, Washington, is made primarily with the use of hydroelectric power, harvested nearby. This is done to minimize the effect that BMW i3 production has on the environment. Since more than 10% of the carbon fiber needed to manufacture the BMW i3 is made from recycled materials, it is another way the BMW i3 is completely sustainable. The roof is made of CFRP scraps to help recycle left over material from other parts.
5. Explore the World: Vehicle Trim Levels.
Due to the unfamiliarity of electric mobility technology in the United States, buying an EV can be a daunting experience for the average customer. BMW sought to make this process as simple as possible in the new BMW i3. The BMW i3 comes in three different worlds: Mega, Giga and Tera, all of which come equipped with a very high level of standard equipment.
The base Mega World comes standard with 19-inch extra-efficient forged aluminum wheels, BMW Navigation, BMW ConnectedDrive with eCall, the BMW i Remote, an alarm, 7.4 kW on board charger and LED headlights, DRLs and tail lights. The interior is donned in bright, lightweight Sensatec and sustainable cloth, which is made from recycled materials. It also features a leather trimmed steering wheel and grained dash trim.
The next level, Giga World, has all the features of the Mega World but with the addition of distinct Giga-specific 19-inch wheels and an interior wrapped in leather and wool cloth. A universal garage door opener is included for easy access to the i3's BMW i Charging Station, which is usually mounted in the garage. It also has Comfort Access, a sunroof, and satellite radio. The leather-trimmed steering wears contrasting stitching to give a classy, sporty look.
The top-of-the-line Tera World, adds unique 19-inch wheels, a luxurious full leather, olive leaf-tanned interior, with textile accents and contrasting stitching, and anthracite floors mats.
Available for every world is the Technology and Driving assist, and the Parking assist packages. The Technology and Driving Assist package adds a host of convenience and safety technologies to the BMW i3. It includes the wide-screen Navigation Professional with advanced real-time traffic and the new touch pad, Traffic Jam Assist, BMW Assist with Enhanced Bluetooth and USB with BMW Apps, Online Information services, Deceleration Assistant, ACC Stop & Go, Speed Limit info, BMW ConnectedDrive services, Forward Collision Warning, Pedestrian Protection and City Collision Mitigation. The Parking Assist package is ideal for living in the city and includes a rearview camera, Park Assistant, which helps take advantage of tight parallel parking opportunities, and Front Auto Park Distance Control.
The BMW i3 full options list for USA will be released Fall 2013.
6. BMW ConnectedDrive. Mobility services and new driver assistance systems.
BMW ConnectedDrive is the interface between the customer, their car, 360 Electric, and the Premium Mobility Service. Connected mobility is the embodiment of an individual, sustainable, efficient and convenient form of urban mobility. It is a crucial part of the BMW i and urban lifestyle.
An embedded SIM card in the BMW i3 is the key that unlocks the BMW ConnectedDrive services, available to the new electric model. A feature of BMW ConnectedDrive is BMW i Navigation, which can search for a nearby charging station, which should give the driver piece of mind, knowing that there is a station nearby. It can also give a real world range estimate and visualization of the estimate with the SpiderMap, Real Time Traffic Information and plan a route that avoids the traffic as best as possible.
The customer has access to personal assistance from a BMW ConnectedDrive agent at any time of the day or night. Concierge Service can help answer almost any of the driver's questions. They can recommend restaurants, give information on destinations or guide the driver to the nearest charging station, among other things.
In the unfortunate situation when an accident occurs, Intelligent Emergency Call ("eCall") sends information like location, number of front-seat occupants, and even crash severity data to the BMW ConnectedDrive Call Center, which quickly informs the appropriate 911-dispatch center.
BMW ConnectedDrive can also connect directly with your iPhone with an original Apple cable that connects to the car and built-in BMW Apps.
The optionally available Driving Assistant Plus for the BMW i3 comprises Collision Warning with brake priming function, which is activated at speeds up to about 35 mph (60 km/h) and is able to respond to both moving and stationary vehicles ahead, as well as to pedestrians. It also comes with Active Cruise Control including Stop & Go function. In addition to visual and audible warnings, the system is capable of braking the vehicle by itself, if required, with up to maximum stopping power. The Parking Assistant can also be found on the option list and performs the steering maneuvers at the same time as controlling accelerator, brake and gear selection, enabling fully automated parallel parking. Another handy optional extra is the Traffic Jam Assistant that allows drivers to delegate the tasks of pulling away, braking and steering to keep the vehicle in lane. Meanwhile, the Speed Limit Info system is also offered.
7. 360 Electric: Support and Convenience for Electric Mobility.
Electric cars differ drastically from their gas-powered counterparts, and the 360 Electric features further that differential. All of the 360 Electric features help to ensure convenient electro mobility in most situations.
If the BMW i3 buyer has a private parking space at their home, BMW i will offer a home charging station, which includes a BMW i charging station for convenient charging. They will even send a representative to install it to any specific need. 360 Electric will also help with public charging by locating the nearest station.
As part of 360 Electric, the BMW i Remote app links to your car and can monitor its battery level, charging status and other charging-related functions, such as heating and air conditioning. The app can also give the cars location, lock or unlock the doors, honk the horn, or flash the lights.
Before driving away in the BMW i3, it is recommended to precondition that battery to the preferred operating temperature of between 60 - 70 degrees Fahrenheit to optimize range. Battery temperature may be monitored through the iDrive system. The battery liquid cooling system keeps the battery at the ideal operating temperature which increases performance and life expectancy. Battery condition is controlled and operated in harmony by the intelligent energy management system. This, combined with Brake Energy Regeneration system extends the vehicle's range while enhancing its performance.
The Range Assistant is engaged both for route planning and during journeys already under way. Topographical mapping technology helps find the most efficient route to your destination by calculating distance, elevation and other factors, in order to get the best range from your BMW i3. If the destination is beyond the cars range, it can suggest switching to ECO PRO or ECO PRO+ to get more from the battery's charge.
In the unlikely circumstance of a breakdown, the BMW Assist Safety Plan provides contact with a Response Specialist at the touch of a button.
BMW Assist also introduces Navigation services specially-developed to enhance electric mobility alongside familiar features including the Concierge Services information facility and the intelligent BMW Assist eCall. Moreover, drivers may use the BMW i Remote app to share information with their car using a smartphone. The pedestrian navigation function guides the driver from parking place to their final destination and back.
8. Safety: Always a true BMW.
From an efficiency standpoint, the body of the BMW i3 needs to be not only strong but, above all, light. However, from a safety point of view, it has to be not only light but, above all, strong. This apparent conflict of interests highlights the engineers' pioneering work in developing the vehicle architecture of the BMW i3. Here, there is no contradiction between lightweight construction and safety. Quite the opposite, in fact: the LifeDrive concept of the BMW i3, with its combination of aluminum and carbon-fiber-reinforced plastic (CFRP), is on a par with other structures and even performs better in some areas of crash testing despite its lightweight design. The use of CFRP essentially allows the construction of extremely lightweight bodies. Moreover, CFRP possesses an impressive ability to absorb energy and is extremely damage-tolerant. CFRP is the lightest material that can be used in the construction of car bodies without compromising on safety.
The LifeDrive concept is based around two horizontally separate independent modules. The Drive module – the aluminum chassis – gives the car its high-strength foundations and integrates the battery and drive system into a single structure. The Life module, meanwhile, consists principally of a high-strength and extremely lightweight passenger compartment made from CFRP. With this innovative concept, the BMW Group takes the combination of lightweight design, vehicle architecture and crash safety to an entirely new dimension.
LifeDrive module offers tremendous safety.
The crash requirements in automotive manufacture are very strict. Numerous impact criteria stipulated by the stringent guidelines of global consumer protection organizations and legislators have to be taken into account. During the development of the BMW i3 concept, there was close consultation with the international crash test institutes on the innovative car body and safety concept of the BMW i models.
The high-strength passenger compartment teams up with the intelligent distribution of forces within the LifeDrive module to provide the cornerstones for optimum occupant protection. Even after the structurally-debilitating offset front crash at 64 km/h (40 mph), the extremely rigid material maintains an intact survival space for passengers. The crash-activated aluminum structures at the front and rear end of the Drive module provide additional safety, so that less body deformation occurs compared with comparable steel bodies. Furthermore, the "cocoon effect" of the CFRP car body ensures that the doors can be opened without any problem and the interior remains largely free of any intrusions.
Even rescue scenarios have been worked through and checked. In standard cutting tests, the process of rescuing occupants from a BMW i3 involved in an accident was comparable to that for a conventional vehicle. In some respects, indeed, it was more straightforward since the lighter components can be more easily cut than high-strength steels, for example.
Impressive rigidity, combined with its ability to absorb an enormous amount of energy, makes CFRP extremely damage-tolerant. Even at high impact speeds it displays barely any deformation. As in a Formula One cockpit, this exceptionally stiff material provides an extremely strong survival space. Furthermore, the body remains intact in a front or rear-on impact, and the doors still open without a problem after a crash.
In its dry, resin-free state CFRP can be worked almost like a textile, and as such allows a high degree of flexibility in how it is shaped. The composite only gains its rigid, final form after the resin injected into the lattice has hardened. This makes it at least as durable as steel, but it is much more lightweight.
The high tear resistance along the length of the fibers also allows CFRP components to be given a high-strength design by following their direction of loading. To this end, the fibers are arranged within the component according to their load characteristics. By overlaying the fiber alignment, components can also be strengthened against load in several different directions. In this way, the components can be given a significantly more efficient and effective design than is possible with any other material that is equally durable in all directions – such as metal. This, in turn, allows further reductions in terms of both material use and weight, leading to another new wave of savings potential. The lower accelerated mass in the event of a crash means that energy-absorbing structures can be scaled back, cutting the weight of the vehicle.
Superior protection in a side impact.
The ability of CFRP to absorb energy is truly extraordinary. Pole impacts and side-on collisions both highlight the impressive safety-enhancing properties of CFRP. Despite the heavy, in some cases concentrated forces, the material barely sustains a dent, and passengers enjoy nearly unbeatable protection. All of which makes CFRP perfectly suited for use in a vehicle's flanks, where every centimeter of undamaged interior is invaluable. However, there are limits to what CFRP can endure. If the forces applied go beyond the limits of the material's strength, the composite of fibers breaks up into its individual components in a controlled process.
In the Euro NCAP side impact test, in which a pole strikes the side of the vehicle dead-center at 32 km/h (20 mph), the carbon fiber composite also demonstrates its extraordinary energy-absorbing capacity. The Life module absorbs the entire impact with minimal deformation, guaranteeing optimum passenger protection. Even as CFRP dissipates energy, danger to passengers or other road users is substantially mitigated.
The best of both worlds: combining aluminum and CFRP.
The new Drive module has also been carefully designed and structured with these exacting crash requirements in mind. Crash-active aluminum structures in the front and rear sections of the vehicle provide additional safety. In a front or rear-on collision, these absorb a large proportion of the energy generated. The battery, meanwhile, is mounted in the underbody section of the car to give it the best possible degree of protection. Statistically, this is the area that absorbs the least energy in the event of a crash, and the vehicle shows barely any deformation here as a result. Moreover, positioning the battery in the underbody allows the BMW Group development engineers to give the vehicle an ideal low center of gravity, which makes it extremely agile and unlikely to roll over.
The high-voltage battery also benefits from the excellent deformation properties of the CFRP Life module. In the side crash test, the pole does not penetrate as far as the battery. The mix of materials used and the intelligent power distribution in the LifeDrive module ensure that the high-voltage battery is optimally protected even in the side sill area.
All in all, the high-strength CFRP passenger cell teams up with the intelligent distribution of forces in the LifeDrive module to lay the foundations for optimum occupant protection.
Post-crash notification.
In the unfortunate situation when an accident occurs, Intelligent Emergency Call ("eCall") sends information like location, number of front-seat occupants, and even crash severity data to the BMW ConnectedDrive Call Center, which quickly informs the appropriate 911-dispatch center.
Lithium-ion batteries are safe even in the event of a fire.
Safety is a key criterion in the development of the BMW i models. A range of systems and measures have been implemented in the vehicle that ensure safety in normal operation and in the event of accidental fires. The high-voltage system is designed to cope with accidents beyond the legal requirements, with the high-voltage battery including features that ensure its safe reaction even in situations such as this.
The latest series of tests conducted by the renowned DEKRA E-Mobility Competence Center were extremely extensive – ranging from how a car might catch fire, how the flames might spread and what would be required to extinguish the fire, to the pollution caused by run-off of the water used for fighting the fire. The experts concluded that electric and hybrid cars with lithium-ion drive system batteries are at least as safe as vehicles with conventional drive systems in the event of fire.
To ensure maximum safety in such a crash scenario, the high-voltage battery is disconnected from the high-voltage system and the connected components discharged when the passenger restraint systems are triggered. This safely prevents the possibility of a short circuit, which could lead to electric shocks or cause a fire.
