The 2011 Ford Mustang GT features the new 5.0L Ti-VCT V8 engine. Packing 412 horsepower and 390 lb-ft of torque, the engine produces 97 hp and 65 lb-ft more than the 4.6-liter V8 used in the 2010 Mustang GT. Despite the added power, Ford projects fuel economy will rise to 17 city / 25 highway (up from 17 city / 23 highway) for models equipped with a six-speed automatic transmission. The fuel economy rating for the six-speed manual will remain unchanged at 16 city / 24 mpg highway. To squeeze out the extra mileage, Ford equipped the car with Twin Independent Variable Camshaft Timing (Ti-VCT), an Electric Power Assist Steering (EPAS) system, and an additional rear decklid seal (to improve aerodynamics).
