It will be an interesting to see what BMW claims, historically those figures seem to be set more by the marketing department than design or manufacturing.
Having put my '00 M on the dyno recently, and compared numbers with several other M coupe/reoadster/M3 drivers who did the same (thanks, Fred Estevez, for organizing) BMW HP and torque #s for the M coupes and roadsters are lowballed - we all beat advertised numbers handily. What is interesting is that M3s with the same engine turned in lower numbers than the coupes and roadsters. The racing shop where we did the dyno tests believed that this is due to a more constrictive exhaust on the M3.
