The most hard-edged version of the M3, the CSL is the lightened, small-run edition of BMW's definitive sports coupe. The last version of the CSL sported more power than the standard M3, tuned suspension geometry, and a wider track, among other tweaks. Specs for the version have not yet been released, however BMW has publicly admitted in the past that it was building an E92 CSL. Considering how long the standard M3 underwent testing we don't expect the CSL to arrive before 2009.
For those that just can't wait, the folks at G-Power will be more than happy to fit a V10 from the M5 into your donor M3, as we reported just a short while ago.
