Straight line acceleration is not everything.

A lot of Detroit musles are faster than many expensive cars but, who cares, as other cars, you know, especially those front wheel drive v6 mid size sedan. And don't compare old 3ers with current v6 accord and altima, or let's say the only 1 year E90 330i was already faster than the 298hp G35, an altima just a piece of cake.
