Ford Mustang Spy Shots Hint to a More Extreme GT350 - or a GT500

Spy shots revealing what appears to be a Ford Shelby GT350R Mustang with more extreme aero bits could reveal something as simple as upgrades for the GT350 line, or they could be the best shots yet of the rumored Shelby GT500 Mustang.

The folks at have proven to be the authority on inside information on the newest generation of the Ford Mustang and this time, the community has rolled out some pretty interesting images. A member of their forum posted images which reportedly come from inside a Ford Motor Company facility and in these images we see what appears to be a Shelby GT350R Mustang test mule, but there are a handful of features which make this car unique from the current GT350R.

These differences – which we detail below – suggest that the Motor Company is either working on a more extreme aerodynamics package for the Shelby GT350R Mustang, or they are using GT350R Mustangs as test mules for the long-rumored Shelby GT500. In any case, it certainly looks as though Ford is cooking up something special for the Shelby Mustang.

The Mystery Shelby Mustang
In these spy shots (which you can check out over at, the camouflaged Ford Mustang appears to be a Shelby GT350R model. It has the carbon fiber wheels and the monster Brembo brakes from the current Shelby models, but it has a heavily masked front end and a larger rear spoiler which looks to be adjustable. The front fascia is covered with the thick black cladding so we can’t really see what is going on up front, but we can see in one of the images that this Mustang has louvers in the fenders above the front wheels. Finally, this mysterious Mustang has a hood wrapped in the thick black camo, but in one image where the hood is closed, it appears to have more of a bulge to it than any standard Mustang hood right now.

So this Ford Mustang has a covered front fascia (suggesting that it is unique from current production designs), a hood which looks to have more of a bulge than current production models, fender vents that we have never seen on any road-going Mustang and a rear spoiler that looks to be a bit more extreme than the Shelby GT350R wing – but why?

There are a few possible reasons why this Ford Mustang exists.

  • First and foremost, the company could be testing components for the future Shelby GT350R model, which would clearly have more extreme aero bits than the current model.
  • Next, this could be nothing more than a development model with some unique bits that they are testing without any future plans of using them on a specific model.
  • Finally, this Shelby GT350R Mustang with unique bits could be offering us our first look at the long-rumored Shelby GT500. The guy who posted these images went on later in the thread to claim that this car was initially supposed to be fitted with twin turbos, but they have since gone to a supercharger although he doesn’t go into any detail on what engine has been fitted with the forced induction setup. If this car really does have a supercharged V8 with the unique aerodynamic package, the lightweight carbon fiber wheels and the high performance brakes – it could be an early GT500 test mule.

We have only included this closely-cropped image which shows the least detail, as we don’t want to steal Mustang6g’s thunder, but you can check out all of the images on their forum by clicking here.
