BMW is again preparing the super sports version of the new M 3-Series, the CSL. A CSL variant was already available in the line up of the last M 3-series. It was particularly lightweight with only 1425 kg, and the new one is expected to follow up.

On the photos of the test car one can recognize in the front-side view the black aerodynamic device (?) on both fenders, which help to keep the fast car on track.

The pictured prototype is undisguised except for the BMW emblem on the hood, which has a little tape on top.
