BMW M4 CS

The M4 CS is as extreme as the M3 but a little lighter and slightly more compact. BMW has even ripped out the door panels to reduce weight and given the car that little extra bit of power-to-weight advantage. For those who do not need to use the rear seat much, this is a good alternative to the M3. It is powered by the same straight six turbo engine that powers the M3 and has similar performance figures as the M3 CS.
