Roll on race video - Porsche 997.2 GT3 RS 4.0 versus Audi R8 V10
First of all, we want to point out the disparity in the engines here. The Audi has a 5.2 liter direct injected V10 that revs to 8700 rpm and is rated at 518 horses. The GT3 RS 4.0 has a comparatively small 6 cylinder at 4.0 liters that puts out an amazing 500 horses. The Audi should win but does not even with the drag from the aerodynamic enhancements on the GT3 RS 4.0. Why? Well, the GT3 is lighter and routes its power to the rear wheels and not all four. It also puts out a lot of power to the wheels despite only 6 cylinders and 4.0 liters
. Very, very impressive vehicle.
