We just spied the 2018 Shelby GT500 Mustang for the first time while it was leaving Ford’s Dearborn Development Grounds!
The S550 GT500 prototype disguises a modified front end that will surely build upon the 2018 Mustang cosmetic refresh that is widely expected. Its outline shows deep breathing intakes and an aggressive bulging hood hiding its forced induction powers underneath.
This hot Mustang prototype was riding on aggressive Michelin Pilot Sport Cup tires, and featured Brembo brakes with cross-drilled rotors. In the rear it shows a large fixed wing and quad-tipped exhaust similar to the GT350.
One thing that could be very telling on this prototype is a windshield sticker that reads “TT-0081” which is the same TT designation that has been spotted on Ford’s SVT Raptor pickups (pictured below) which also uses a twin-turbocharged engine.
Based on the information we’ve received and this potential tipping of the hand, it is very possible the next iteration of the Shelby GT500 will sport a twin-turbocharged V8.
