The camouflage is heaviest at the front, where the prototype appears to have a much more aggressive front end than Ford's current track-oriented Mustangs. The hood is larger, while the air intakes have also grown in size. At the back, there's a massive wing that dwarfs the one found on the GT350R.
The prototype is riding on Michelin Pilot Sport Cup tires, which is a step above the GT350's Michelin Pilot Super Sports and just below the Michelin Pilot Sport Cup 2 rubber on the GT350R. The brakes come courtesy of Brembo and utilize cross-drilled rotors.
While the Mustang tried to dodge our photographers' cameras by weaving through traffic, they managed to spot a sticker on the windshield that reads "TT-0081." The same "TT" designation was spotted on Ford SVT Raptor pickup prototypes and could be indicative of a turbocharged engine. With rumors indicating that the next GT500 should put out between 750 and 800 horsepower, a turbocharged engine would help Ford take the battle to the Chevrolet Camaro ZL1 and Dodge Challenger SRT Hellcat. Let's hope that's what we're looking at here.
