We’ve received confirmation that BMW is developing plans for the M5 and M6 in all-wheel-drive from no less than BMW's M division chief Dr. Friedrich Nitschke. There have been rumors for many years about the possibility that the M5 and M6 will come in AWD. BMW likely felt that it had to catch up to its rivals, Mercedes' AMG and Audi's RS models, which already offer AWD in their lineup.
However, fans have a long time to wait as the M5 AWD and M6 AWD would probably be released only after several years. This technology will be used first on the M5, a year after the release of the next generation 5-series either in 2016 or 2017. Before, the M division had the X5 M and the X6 M. However, the two are based on an all-wheel-drive architecture.
Meanwhile, the M5 and M6 are based on a rear-wheel-drive system. Furthermore, Nitschke asserted that the M3 and M4 will not be distancing from its highly impressive rear-wheel-drive architecture.
