The car was originally meant to be launched in the middle of next year but instead the M division engineers will now focus on developing new performance variants of the X5 and X6 – both of which have been spotted testing on both sides of the Atlantic. If the CSL had been built, it would have featured a power output of somewhere between 450 and 470hp (335-350kW) along with a chassis 100kg lighter than the standard M3, plus competition tires and plenty of carbon-fiber accessories.
Speaking with CAR, Willisch said that “based on current numbers, there is most likely insufficient demand for the M3 CSL.’ As for the rest of the M range, Willisch previously revealed that there will be no M3 Touring model, no 1-series based M car and definitely no M1 supercar.
