The E60 M5 was 507, the F10 is 550. The E9X M3 was 414, the new F8X is supposed to be 450. I think that's a decent increase.
I agree...BMW is kind of going overboard making the M3 AND M4 AND giving it a different chassis designation. Unfortunately, I think the BMW marketing department is too in love with Audi.
Either way, I think the new M3 is going to be as brilliant a dual duty daily driver/track car as the M5 is an executive express.
