So it rates 18hp less at the engine compared to the 335i, according to BMW, but puts down about 40 less rear wheel HP then the 335i. So it looks like the 335i is indeed making about 320hp at the engine.
Sounds about right. 282 flywheel hp down to 232 rear wheel hp = 17.7% loss through drive train. 429 flywheel lbft down to 378 rear wheel lbft = 11.9% loss through drivetrain.

I know the 335d and 335i are obviously very different engines, but simply applying the two %-ages above to the 335i engine's rear wheel figures of 275hp and 300 lbft gives us flywheel figures of 324hp and 336 lbft

Momma says dat horsepower depends on the kind of horse you usin

lol. it boils down to what makes you more happy to drive. I've driven both cars and teh 335 makes me all tingly inside. And since I'm not interested in racing it for now, the numbers don't matter. besides 335 or m3... both are faster and better crafted than most cars on the road in the US. In this holiday season lets be thankful for two amazing sport coupes and the fact that the 335 has a magic gnome that hands you your seatbelt when you're ready to drive.

That's what the m3 doesn't have, seatbelt-gnome power!
