The rumor started because of BMW's "4 cars, 1 day" video which shows a graphic at the end with the M2/M3CS/CSL and a "M Prototype" listed last with the time blurred out. First, you need to assume this is the M4 CS, which is probable but not confirmed. Second, you need to assume the M Proto time is faster only on the basis that it is listed last in the graphic.
Logic would dictate there are two plausible outcomes a) this is the M4 CS and they deliberately put it last so as not to reveal the actual position (e.g. faster or slower than the M3 CS). Or b) the M prototype is a completely different mule perhaps with a mild hybrid system or full electric making huge power.
Of these, a) seems the most probable. We should know in January.

The common variable for the “4 cars, 1 day” video is the S58. The prototype is the M4CS, as BMW has its product road map 10 years out and M4CS was developed years ago when the G8x platform was R&D. BMW is all about cost cutting and eccomies of scale these days. Look at the S68 now being used in M performance models such as the M60i for the X7/X6/X5. I belive that full EV is years away for being useful on the Ring. Maybe it was the P58 engine in the prototype.
