More great exclusive pics, thanks Jason. It's getting harder and harder to decide between a 2013 with the last NA or wait for this car which I'm sure will tick all the boxes.
While I'm far more concerned with the overall package than raw power(hence why I drive an M3), I think this engine will put out closer to 470bhp than the 450 oft repeated. 450 would mean it would be 102 behind the M5, while the Euro E36-E34 differential was 21bhp, the E46-E39 differential was 61bhp and the E92-E60 differential 86bhp. So, while 102 would follow the trend, lI really don't think it will keep rising but I'll admit this is just an educated guess.
