You're measuring at the rear wheels, yes? Then I'd say they're better than BMWs numbers which are presumably just the engine?

Funny thing was when I first test drove an M40i and was worried about the power compared to my V8 Ftype, the sales manager said that BMW typically underrates their engines and that the net flywheel rating would be what I could expect at the rear wheels.....guess he was right on the money. Car certainly felt faster than I expected though the 400lb weight advantage vs. my F type was responsible for some of that... Dave |

15% on a 1000hp engine would be 150hp loss but only 15hp loss in a 100hp engine. My M4 has about 64hp loss in the driveline. That would be 64hp loss nomatter how many hp it has, right?
