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.

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.

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.

Will go under the hammer at the Barrett-Jackson Las Vegas auction in September

Ford has announced plans to auction off the 1,964th Mustang 50 Year Limited Edition at the Barrett-Jackson Las Vegas auction in September.

The special edition is based on the Mustang GT and comes nicely equipped with two-tone leather upholstery, the Performance Package and 19-inch alloy wheels with Pirelli P Zero tires. The model also has a 5.0-liter V8 engine that develops 435 bhp (324 kW) and 400 lb-ft (541 Nm) of torque. The car will also be outfitted with a one-off pace car package as well as signatures from Bill Ford and "other Ford executives."

The winning bidder will receive a VIP package to the Ford EcoBoost 400 NASCAR Sprint Cup at the Homestead-Miami Speedway on November 16th. The package includes airfare, hotel accommodations and two VIP tickets to the event.

Proceeds from the auction will benefit the Edith and Benson Ford Heart & Vascular Institute which is billed as a "leader and innovator in comprehensive cardiovascular care, research and education."
