All last year, renderings flooded the world wide web of what the new S550 Mustang might entail, and on December 5, 2013, enthusiasts got their first glimpse of the real deal as the covers came off simultaneously in six cities on four different continents.

While the wait is finally over, a prototype has been spotted that could very well be the next GT350 Mustang. Not hiding the general shape of the car, this test vehicle is sporting less vinyl camouflage than what we are used to and looks to be hiding some pretty important details.

While the new S550 Mustang GT has been revealed with twin exhaust pipes, the car spotted here is revealing a large quad-tip exhaust below the rear bumper. On top of that, fat rear rubber (295/35/R19) is spied hinting that this car is likely packing a serious punch.

Checking out the concealed front end, it is obvious that this car is hiding a large cooling air vent in the hood with signs pointing towards forced induction. We all know that the last Shelby GT500 was boasting an incredible 662hp out of a supercharged 6.2L V-8, but don’t expect that to be under the hood here since it is too big to be cramped inside of the 2015 engine bay.

Other options point toward a naturally-aspirated 5.0L V-8, but the photos suggest the possibility of a supercharger. With a new engine option given to the 2015 Ford Mustang in the form of a turbocharged 2.3L inline-four EcoBoost engine, the possibility of a high-performance turbo GT350 model isn’t out of the question either.

When the ’15 Mustang was revealed in December, chief engineer Dave Pericak wouldn’t confirm or deny whether the GT350 was in the works, but it looks like the question is finally answered. We probably won’t see the final result until late this year after some of the existing Mustang hype wears down.

Three engine options were given to the ’15 Mustang: a 3.7L V-6 good for 300hp, a revamped 5.0L V-8 rated at 420hp, and the new turbocharged 2.3L inline-four EcoBoost capable of 305hp.

Ford may be dropping the Shelby name but keeping GT350 badge. However, rumors have been swirling about possibly bringing back the Mach 1 or Cobra. What do you think this could be?
