Mustang fanatics predicted it and now Ford has officially confirmed that the 2011 Mustang GT will come with a new 5.0 liter V8 engine. The previous model featured a 4.6L V8 that was doing nothing less than 315hp and 325lb-ft of torque, while the upgraded engine will take the pony count to 412hp at 390lb-ft of torque and it will also improve the car’s fuel efficiency even though there’s a six-speed automatic transmission mated to the engine — 17mpg in the city and 25mpg on the highway. The extra mileage is courtesy of a combination of Ti-VCT, EPAS systems and an additional rear decklid seal that specifically improves aerodynamics. As for those who’d like the old six-speed manual, there aren’t any changes for that one.
