Rumors have been circulating for many years that BMW will produce their M5 and M6 in all-wheel-drive (AWD) but so far they have not become reality. However, the likelihood looks set to change after BMW's M division chief Dr. Friedrich Nitschke has confirmed the company is working on plans for an M5 and M6 all-wheel-drive future.

Competitors such as Mercedes' AMG and Audi's RS models already boast AWD in their line-up which has left the Bavarian automaker playing catchup. However, it is still going to be many years until we see the M5 AWD and M6 AWD. The M5 is first in-line to receive the technology, following a year on from the next generation 5-series that is expected in 2016 or 2017.

The M division already has the X5 M and the X6 M, but both are based on an all-wheel-drive architecture while the M5 and M6 are based on a rear-wheel-drive system. Nitschke also confirmed that the M3 and M4 will never stray from their rear-wheel-drive architecture that he describes as fantastic.
