However, I am very excited to see what the M2 will bring. It seems to me that M3 and higher have been relegated to really great touring cars. I hope the M2 shows up as the raw motorsports car that the M3 used to be.
PS. Fuck CAFE.
The BMW Formula 1 engine circa 1983 was based on a stock engine, it revved to around 11,000 rpm was turbo charged and produced over 1400hp. Still a world record for a 1500cc engine and possibly bhp /cc nearly 20 years later.
If that is not good enough for you WTF is?
An engine consists of a block, with pistons and rods, and a head. All the magic happens in the head and induction system. Yes the M3 might share the bottom end of a more mundane 3 series (sic.), but it does have a unique to M3 head and induction system. That's all that matters.
