BMW is currently working on the next-generation BMW M5, which is expected to arrive sometime around 2016 or 2017. Germany’s Auto Motor und Sport spoke to BMW M’s president Friedrich Nitschke, who provided some hints about the next M5.
Nitschke told the magazine that the current M5 is "suffering," and will likely get some big changes to hopefully improve its sales. One of the big additions could be all-wheel-drive to get it better driveability on wet roads. But he also stated that in order for the next M5 to be able to get an all-wheel-drive system, the M5 needs to drop more weight than the 2015 M3 and M4 models did. The 2015 M4 Coupe is around 176 pounds lighter than the previous M3 Coupe.
Rumors about an all-wheel-drive M5 and M6 have been circulating for years and since BMW already offers the X5 M and X6 M all-wheel-drive models, that are closely related to the M5 and M6, it shouldn't be too hard to make it happen.
