So what's under the hood? A 3.8 liter turbocharged flat-6 based on the Turbo S so output should exceed the 991 Turbo S 560 horsepower especially considering the power is going to the rear wheels and not all four. Will it have over 600 horses or will Porsche reserve that for a GT2 RS model? We will have to wait and see.
Regardless with the addition of a PDK transmission just like the 991 GT3 and with more power as well as less weight than the 997 GT2 this will be a ballistic missile for the road. Quite simply, this is the king of the 911's.
Expect the car next year, photos below.
