Although the BMW M2 has earned the sort of rave reviews that the famous M Division had been falling short of in the few years before its release, the Munich speed freaks have kept their feet well and truly on the loud pedal with an even madder M2.

The M2 CS will use the S55 double-blown straight-six from the M3/M4 brothers to give an extra performance kick over the usual M2 motor, which is apparently close to its performance limits bearing in mind cooling and reliability. There’s also speculation that using the S55 platform will allow better production efficiency for an M2 GTS to follow the CS as the M2’s run-out final hurrah.

It’s a car we’ve known about for a while, but now we know how powerful it’ll be, courtesy of a new report in Car Magazine.
