While conducting the record attempts for the M4 CSL, M3 CS, and M2, BMW lapped a secret fourth vehicle around the Nurburgring. The car looks to be an M4 CS from the spy shots at the Nurburgring, but has only officially been referred to as the “BMW M Prototype.” If this car could combine the extreme weight savings from the CSL with the xDrive system from the CS and add a bit more power, it’s plausible that the lap time could be quicker than the M4 CSL. BMW blurred the Prototype’s lap time, but it’s positioning at the bottom hints that it could be the ultimate Ultimate Driving Machine.
Stay tuned for more information about this mysterious M Prototype.
