"As far as your 100hp per liter, may be something to brag about, but it doesn't really matter when the C63 motor is pushing out 30hp/150 ft-lbs more power. Its going to flat smoke the new M3."

Again, you look for output numbers alone. It will flat smoke the new M3 in a straight line, i agree it's very possible but i'm not so sure about the bends.

"With its titanic 148-pound-foot torque advantage, it means never having to wring a car's 8300-rpm neck to pass an RV."

Neither do i compared to an F1

I wasted my time here with this engine d-bate. Too bad...
