Our spy shooters grew suspicious when they saw this seemingly normal-looking M5 appearing to turn all four wheels during ice testing. They checked it out and snapped these shots underneath clearly showing power routed to the front axle.
While this shows that the tech is at least being tested on a current-gen M5, all-wheel drive is probably not coming until the next 5 Series model, which is already being evaluated. The idea of power going to the front and rear axles for this sport sedan might polarize some hardcore brand fans as a break with tradition. However, the head of the M division thinks the change is a priority to actually put torque down effectively. The future vehicle is slated to get at least 600 horsepower and pack it into a lighter platform. Rear-drive M5 purists can take heart, though. The all-wheel-drive system would reportedly be an option, and it would be rear-biased to still let drivers hang the tail out, if the desire arises.
