Hot on the heels of yesterday's announcement about the Agrera RS, Koenigsegg has confirmed plans to introduce a mysterious Regera at the Geneva Motor Show.

The company is keeping details a closely guarded secret but they're referring to the model as a "megacar." This is likely a subtle hint that the Regera will produce at least 1 megawatt (1,341 bhp / 986 kW) of power.

While nothing is official, Koenigsegg referred to their One:1 as the "world's first megacar." It has a twin-turbo 5.0-liter V8 engine that develops 1,341 bhp (986 kW) and 1,371 Nm (1,011 lb-ft) of torque. This enables the model to run from 0-400 km/h (0-248 mph) in approximately 20 seconds.

Could have a regenerative braking

Koenigsegg has shared the second teaser image of the Regera “megacar”, set for a debut during the Geneva Motor Show.

The design sketch of the model shows it will feature a new headlight design and a One:1-like air intakes in the front bumper. The company is still coy on details as the only thing we know about the car is that it will be a “megacar”, probably hinting it will have at least 1 megawatt (1,341 bhp / 986 kW) of power.

According to some reports, the ‘Reg’ in the name comes as a reference to a regenerative system, probably fitted on the brake system. The model will be fully revealed on March 3 at the Geneva Motor Show.

Could be the most poweful and fastest production car in the world

The Koenigsegg Regera will reportedly be powered by a hybrid system that includes a 690 bhp (515 kW) electric motor.

According to EVO, the model, set to be fully unveiled during the Geneva Motor Show in two weeks, will be the most powerful and fastest accelerating production car ever. The ‘megacar’ will have a petrol engine, supported by a 690 bhp (515 kW) electric motor.

Our source also says the Regera will be a completely new vehicle, different to the Agera. It will likely receive a more luxurious interior and be more lightweight and faster than the Agera.

Will have 1,341 bhp

Koenigsegg has released a short teaser clip of their upcoming Regera , confirming the megacar will adopt a plug-in hybrid system.

The video shows an electrically-operated cap making extensive use of carbon fiber while the attached spy shots reveal a substantially different design compared to recent Koenigsegg models. Noticeable are the vented rear fenders and a massive diffuser hosting a large central oval exhaust while the slender LED taillights have an interesting shape.

Koenigsegg says the Regera will be a "megacar" just like the One:1 which means it will have a maximum power output of 1,341 bhp (986 kW). However, while the One:1 is powered exclusively by a twin-turbo V8 5.0-liter engine, the Regera is believed to adopt a 690 bhp (515 kW) electric motor so the conventional engine will generate less power than the V8 inside the One:1.

The latest gossip refers to the Regera as being the fastest accelerating car in the world. We will find out if this is true on Tuesday when Koenigsegg will unveil the car in Geneva.

That's right. The 1,500 horsepower Koenigsegg Regara, the world's almost certainly fastest GT has no gearbox at all. Meet the new era of direct drive.

Okay, so Christian von Koenigsegg has done it again. It's 9:24 am at the Geneva Motor Show, but I don't think anybody can top the Regara when as far as insane engineering goes. I mean, 1,500 hp and no gearbox? I know the Prius has no gearbox either, but this is a whole new level. No need for more coffee, I was all ears.

Get this: Christian came up with an idea just 8 month ago, figured out how to make it happen, patented the technology and now will build 80 Regeras priced at $1.89 million.

Unlike the Agera RS, the Regera was not designed for track duty. Koenigsegg calls it the world's fastest luxury hypercar. Weighing 3,130 pounds dry and 3,589 ready for action, it's 330 pounds heavier than the RS mostly due to 44 pounds worth of sound deadening, electrical seats, rubber engine mounts and a foldable rear wing.

The Regera has 1,500 hp thanks to a twin-turbo combustion engine producing 1,100 on pump gas, and 3 electric motors: one on the crank with 221 pound feet of torque, and two at each rear wheel with 192 ft lb. Thanks to that, you get torque vectoring as well.

Since the gearbox was replaced by a hydraulic clutch, the three lightweight electric motors and a 9 kWh battery pack, Koenigsegg says they saved about 440 pounds compared to having a double clutch gearbox.

The rest is pretty much Christian's traditional recipe with a carbon fiber and aluminum honeycomb chassis, a carbon/kevlar body, active aero, massive carbon-ceramic brakes, hollow carbon wheels, a titanium exhaust system and the signature removable top.

Inside, you'll find the finest leathers with billet aluminum controls and Apple Carplay, and with 21 miles of pure electric range added to the mix, this truly is the most advanced sports car the world has ever seen.

We already knew that the new Koenigsegg Regera had to impress but if the numbers are true, we are entering a whole new level of mind-blowing performance here.

According to the Lovecars blog and their Instagram, the new Swedish monster will produce 1,500hp combined and will get to 400km/h (that’s 248mph!) in under 20 seconds. To get that into perspective a Ferrari LaFerrari scores a shocking 15sec for the 0-300km/h (0-187mph), and the Regera makes it look like a very fast Golf, if the numbers are to believed.

Koenigsegg says that they don’t like traditional hybrids and according to the leak, they use something called Koenigsegg Direct Drive which doesn’t make it a hybrid. The 9kWh battery pack is liquid cooled in order to provide enough juice to 700 electric horses.

Inside the Regera features Apple CarPlay, 3G connection, WiFi and a camera that can record you, probably while you feast on LaFerraris and P1s and 918s.

Official details are landing tomorrow, but until then we’ll keep you updated if we find out any more info on this staggering machine.

It’s true; Koenigsegg has broken every record of sanity with the Regera, a hybrid hypercar with a combined output of 1500hp. However, this is not the only number that gives you a pleasing headache.

Stay with me. One biturbo 5.0-litre 1,100hp V8 lifted from the Agera mated to three electric motors that make an additional 700hp, a liquid-cooled 9.27kWh battery pack and no transmission at all. The powertrain drives directly the rear axle, making the Regera effectively a single-speed vehicle. The final ratio is fixed and there is a locking hydraulic coupling between the crankshaft and the prop. Koenigsegg calls it Koenigsegg Direct Drive (KDD) and claims that the energy losses are reduced up to 50% when compared with traditional transmissions.

Koenigsegg also claims a 0-400km/h (249mph) time in under 20 seconds, which is frankly unbelievable, given a LaFerrari needs 15 seconds to reach 300km/h (186mph) and a Porsche 918 scores 23 seconds for the same sprint. The new liquid-cooled battery pack weighs 115kg and can deliver up to 500KW of juice to the motors. Koenigsegg calculates the combined output at 1.500hp for that reason. There is no info about the top speed though. Yet.

The smaller of the three electric motors is located on the crank, making 160KW-214hp, and works as the starter motor for the V8, fills the torque curve in low rpms when there is turbo lag and harvests energy when the throttle is depressed. The other two, larger motors are located in the rear axle, providing 240hp each, driving directly the wheels with virtually no loss.

Total downforce is set at 450kg at 155mph, helped by a hydraulically operated rear wing. The wheels are made out of carbon and measure 19 inches at the front and 20 inches at the back. The brakes are carbon ceramic as you would have expected already.

Koenigsegg says that the Regera is not destined for hard track use, and calls it instead a more luxurious megacar, with electric seats and added sound insulation compared to the Agera RS. The Regera weighs 1628kg with fluids, remaining relatively lightweight for a car with a huge battery pack and three electric motors.

Koenigsegg will built 80 Regeras all and all, with an early price estimate of around $1.9 million.

The Koenigsegg Regera was the much more interesting car to check out at the Swedish automaker’s Geneva motor show stand. It’s a mind bending collection of numbers and features several unusual technical solutions.

Christian von Koenigsegg really likes to show off the ways in which his company innovates, and we must admit to being completely hooked on it… The man really wants the firm to excel and attract as much attention as possible, and with cars as made as the Regera, they’re managing that brilliantly.

You’ve already heard it has no gearbox whatsoever and that it’s the first car ever to run a direct drive from the engine to the wheels. This is augmented by three electric motors that bring the total power output up to 1,500 hp…

But there’s so much more to it than that, like the reason for choosing the fishtail-style exhausts (no, the big center one is not for the engine, but for cooling the electrics) which are integrated into the rear diffuser arrangement, or the fact that it has soft-closing doors for the first time on a car such as this.

But we’ll let Christian von Koenigsegg guide you through the Regera and also the new Agera RS as well in the two videos posted below courtesy of GT Board.
