If you compare the cars from past generations, you'll see the M3 usually has less displacement and/or less power than the competition from AMG and Quattro GmbH. Despite this, it has been the leader in the segment. So I don't really see them making excuses, nor needing to. They let the results speak for themselves.

It is interesting to me that, when looking at what's going on with IndyCar, even though a twin-turbo setup is allowed, Honda has chosen to use a single turbo (GM uses two). One advantage I think is that the single turbo engine is slightly lighter. I believe Honda has had more success to date, though it may have nothing to do with the induction setup on the engine (there has been a lot of controversy since BW redesigned the Honda compressor cover). Incidentally, the IndyCar engines have more displacement than the F1 engines (2.2L vs. 1.6L), but can only spin up to 12,000 RPM vs. 15,000 RPM for F1. As far as I know, these engines do not use any electric assist for the turbos like the F1 engines are slated to (thanks for posting all of the info, BTW, very interesting stuff) so it would be interesting to know how they perform as far as power delivery.
