New Porsche 911 GT3 RS 4.0 Revealed!

Pictures of the new Porsche 911 GT3 RS have leaked out on the Internet--and this street demon is expected to pack quite a punch.

Displacement will grow to 4.0 liters, which helps to boost output to almost 500 hp. A version of this mill is employed in the competition version of this car as well. In plain English-, this would be a street-legal model of the Porsche RSR. The current car puts out 450 hp from a 3.8-liter, six-cylinder engine.

That's 580 horsepower and 518 lb-ft as measured at the wheels on California's "premium" 91 octane. Yeah, all the ponies are in the stable. And how. Torque hovers right around 500 lb-ft from 3500 to nearly 6000 rpm and barely tapers off as it runs into the fuel cut, resulting in a crushingly wide and flexible powerband.
