Mercedes' in-house performance division AMG is working on a new CLK on 'roids, slotting in between the CLK63 and the homologation special CLK DTM. Called the Black Series, it is expected to be the first in a new line of über-AMGs.

The CLK Black Series, wrapped in a carbon-composite body with beefed up suspension, is expected to molest 530 horses to get it up to sixty in a scant four-and-a-half seconds.
