Only 450 horsepower? It better be able to hit 550-600 with a tune. The m5 engine can hit 725 with minor bolt ons. My current e92 wis already faster than this thing if it only has 450 with minor weight savings. This could be a real disappointment. No V8 and only 30 more horsepower = downgrade in my mind not upgrade.
Clean cars are happy cars!
