An interesting point about BMW vs Audi hp. I strongly disagree though.
There is solid engineering reasoning to support a MINIMUM of 424 hp (actual). Of course since BMW has some history of under rating who knows where the brochure number will end up (and I don't really care too much). Have a look at my post here: http://www.m3post.com/forums/showthr...t=44852&page=3
. Let me know if you think my reasoning is faulty.
