There are some funny numbers here.

C55: 14.4
SLK55: 16.8

M3: 13.0
M3 CSL: 15.1

Are they testing the cars the same way when they measure fuel consumption? The SLK55 is lighter than the C55 and has 2 more gears. Yet it consumes that much more gas??

And the M3 CSL is a super light weight version of the M3, but it also uses significantly more gas??
