The 2015 Ford Mustang promises to be a better car in just about every measurable way compared to the outgoing model. It’s got extra power, a much more advanced chassis and loads of advanced technology. But how will it perform? Let’s explore this car’s weight-to-power ratio.
WEIGHT, WEIGHT… DO TELL ME!
Much to the relief of enthusiasts everywhere the car is NOT dramatically heavier; you could almost hear the internet release a collective sigh of relief when the numbers were posted. Sure it’s put on a few pounds but you might have gained more this year than the Mustang has.
The fastback model with an EcoBoost engine and automatic transmission should be the lightest. They’re expected to check out at 3,524 pounds, which is just six pounds more than a similar six-cylinder 2014 Mustang, its closest competitor since obviously a turbo-four is not currently offered.
The base V6-powered Mustang coupe should gain anywhere between 12 and 30 pounds depending on transmission. Cars with the manual gain more but weigh slightly less. Total mass should measure 3,526 pounds with the manual and 3,530 with the self-shifting gearbox.
With the exception of its base V6 the 2015 ‘Stang is gaining a lot of oomph. The new 2.3-liter EcoBoost four-banger promises to put out a stout 310 hp and 320 lb-ft of torque. With a dual-scroll turbocharger, direct fuel injection and careful tuning it should sound pretty good and offer abundant low-end responsiveness.
But the engine you really want is Ford’s freshly tweaked Coyote V8. The five-point-oh-my-gosh is set to deliver 435 hp and 400 lb-ft of twist. The engine incorporates lessons learned from the Boss 302 program. It features new intake ports, larger valves, more aggressive camshafts and charge-motion control valves in the intake manifold to promote swirl for better drivability and cleaner emissions.
By comparison the 5.0-liter V8 in today’s Mustang delivers a still-impressive 420 hp with 390 lb-ft.
The 2015 car’s entry-level engine remains a 3.7-liter V6. It should put out an even 300 horses and 280 units of twist, five fewer ponies than today’s car. That drop is attributable to a redesigned intake manifold that was necessitated by the hood, which has been lowered by something like 35 millimeters.
Pounds Per Horsepower
One of the best metrics for evaluating a vehicle’s performance capability is looking at its weight-to-power ratio. This is a measure of how many pounds every pony has to lug around. The more mass each equine is saddled with the more blunted the performance should be.
A 2014 Mustang with the V6 engine and a manual transmission weighs about 3,496 pounds. Dividing that figure by 305, which is the car’s horsepower rating, results in 11.46 pounds per horsepower. Not too shabby.
A similarly equipped 2015 model weighs 3,526 pounds and brandishes 300 ponies. Doing the math that works out to about 11.75 pounds per horsepower, slightly worse. An EcoBoost fastback with a stick weighs 3,524 pounds and has 310 horses, numbers that work out to 11.37 pounds per pony, slightly better than the 2014 car can muster. That’s progress, albeit a baby-step forward.
Shifting our attention to the 2014 Mustang GT with a manual, it strains the scale at a burly 3,618 pounds. Dividing that figure by 420 results in a rating of 8.61 pounds per horsepower, which is significantly better than either the V6 or EcoBoost models.
The 2015 equivalent should clock in at 3,705 pounds, which means each one of its 435 ponies is saddled with just 8.52 pounds. That’s a better power-to-weight ratio than an Audi R8 V8 Spyder (8.82) or a Porsche Cayman S PDK (9.16), two very well-respected performance machines.
Looking way back in the rear-view mirror it’s incredible how far the Mustang has come over the last 10 years. For a little perspective a 2004 GT coupe was powered by a SOHC 4.6-liter V8 that delivered just 260 hp, 40 LESS than the new six-cylinder engine despite having almost a liter’s worth of additional displacement! With a curb weight around 3,006 pounds this decade-old car had a weight-to-power ratio of 11.56, only slightly better than the 2015 base model.
For an even more dramatic comparison, check out a 1965 Mustang’s specs. Hardtop models weighed around 2,556 pounds. If customers sidestepped the standard inline-six and opted for the available 289 V8 instead they were treated to 220 horses. Crunching these numbers results in a rating of 11.61 pounds per pony, not as far off as you might expect thanks in large part to the car’s feather-light curb weight.
Just as it did last year with the 2014 Mustang U.S. Air Force Thunderbirds Edition, Ford has built another aviation-themed Mustang GT, this time paying tribute to the F-35 Lightning II fighter jet.
While some may not agree with Ford honoring an airplane that has been grounded for some time because of technical issues, we have to admit the F-35-liveried Mustang doesn’t look half bad.
As before, Ford will donate the unique Mustang to be sold, via auction, at the Gathering of Eagles charity event to support the Experimental Aircraft Association’s (EAA) Young Eagles program, which has provided free introductory flights to more than 1.8 million young people since 1992.
The one-off F-35 Lightning II Edition Mustang is based on the 2015 Ford Mustang GT 5.0-liter Fastback and features a customized glossy and matte titanium paint scheme with distinctive F-35 Lightning II aircraft accents, as well as a carbon fiber front splitter, rear diffuser and rocker moldings.
On the inside, the car features performance gauges, modified instrument clusters, Recaro seats and embroidered F-35 Lightning II elements in the seats and floor mats, among other tweaks.
This Is The 2015 Mustang EcoBoost Engine: Underhood Shot
There’s no denying the 2015 Mustang EcoBoost’s turbo four-pot engine sounds pretty good for what it is, and that it packs a definite punch for its size. But what does it look like in its office? Now we know.
Actually, we still don’t, because like so many modern engines, the direct-injected turbo four under the Mustang’s hood is clad in more plastic than the average Comic-Con cosplayer. Nonetheless, the image, via a dealership employee's post on Reddit, gives us our best idea yet of what’s going on in the engine bay.
What we can see is the engine block is right up against the firewall, explaining part of the car’s rather excellent 52/48 front/rear weight distribution. We can also see just the hint of the turbo and exhaust manifold sticking out below the plastic atop the head.
Another hint gleaned from the position of the turbo (very close to the block) is that the Mustang, like the Focus ST, and the brand’s three-cylinder engines, almost certainly uses an exhaust manifold integrated into the cylinder head. That makes for good efficiency, but it may stymie buyers looking to boost power with aftermarket goodies—or at least put a crimp in the engine’s potential. Thus far, it hasn’t rained on the Focus ST’s parade too hard, however, so there’s always hope.
Other than that, there’s not a whole lot to be seen under the hood of the 2015 Mustang EcoBoost: acres of plastic, a coolant overflow tank, a brake fluid reservoir, some hoses, the hint of the intake hose and throttle body, and the edge of the battery box.
Another factoid, anecdotal as it is, from the Reddit thread: the car photographed was said to be averaging 31 mpg on the highway with the air conditioning on.
We know the regular versions of the 2015 Ford Mustang will be impressive thanks to recent announcements about power and torque output. But there are even hotter versions of the 2015 Mustang in the pipeline, and one of the first will be the GT350.
Our spy shots have already revealed much about the car, in both standard GT350 and possibly racier GT350R trim. But this rendering reveals the curves, lips, spoilers, and other details without the obfuscation of camouflage.
Created by Gurnade, the rendering gives us our best look yet at what to expect. But what can we expect under the seductive skin?
A big V-8 engine is a likely bet, and it will probably be normally aspirated. Rumors of a flat-plane crank have made the rounds, explaining the unique and aggressive sound you can hear in the video of the car in testing below.
Add to the mix an upgraded suspension and braking package, the enhanced aerodynamics and potent V-8 engine are likely to come together with the new 2015 Mustang’s inherent improvements over previous models (independent rear suspension, improved torsional stiffness, and more) to yield an impressive and capable track-worth street car.
All we have now is to wait and see how the final result turns out.
Ford Mustang GT350 to be unveiled on September 19 at Circuit of the Americas
On sale in 2015 as a 2016MY
The Ford Mustang GT350 is going to be introduced at Circuit of the Americas on September 19 during the Continental Tire SportsCar Challenge in Austin, Texas.
During the recent 2014 Indianapolis Motor Speedway race broadcast the announcers said the GT350 will go on sale next year but will be shown on the race track next month. It can only mean the vehicle will be unveiled on September 19 in Austin, Texas at the Circuit of the Americas during the Continental Tire SportsCar Challenge.
The Mustang GT350 is still in development so it's not known at this moment whether Ford will reveal the entire car or will decide to bring a camouflaged prototype. Whatever it will be, under the hood we expect to find a more potent version of the V8 5.0-liter naturally-aspirated engine with considerably more than the 435 bhp & 541 Nm available in the Mustang GT.
It will go on sale as a 2016 model year and will come at a considerable premium over the 32,295 USD Mustang GT. Besides packing more punch, the GT350 will also be distinguished by a very aggressive body along with a stiffer sports suspension, larger wheels, rear diffuser, carbon ceramic brakes, quad exhaust setup and other mechanical tweaks.
