M xDrive: BMW's power + grip solution

Channeling 591 hp (441 kW) and 553 lb·ft (750 N·m) through a pair of hand-sized contact patches was always going to be a challenge, even for the engineers at BMW's M division.

“Four years ago we knew we had to find the right solution for the sixth-generation M5 since it was going to have a considerable power hike,” Dirk Hacker, Vice President Engineering for the M division told Automotive Engineering at the 2017 Frankfurt Motor Show.
