The new M5 can transfer between 4WD, 4WD Sport, or 2WD at the flick of a switch.

BMW promises its new M5 sports sedan will be the most technically advanced example ever – even if it hasn’t been released in full just yet. A more powerful engine and an all-new M xDrive system that can be switched from rear- to all-wheel-drive at the flick of a switch will come standard. BMW details the latter in this new three-minute video.

Revealed:

This is the first time that BMW has equipped its new M xDrive system into one of its vehicles, and just the second time we’ve seen it in a road-going luxury car, following the AMG E63. At start, the M5 defaults to a neutral all-wheel-drive system, but can be switched by the driver using the in-car controls.


Switching to M Dynamic Mode puts the M5 into a "4WD Sport" mode, which increases rear-biased power delivery. Turning the Dynamic Stability Control (DSC) off entirely allows the driver to switch between 4WD, 4WD Sport, and 2WD, if you prefer getting a little sideways. The video explains the three driving modes more in detail.

As far as power is concerned, the new M5 will use a more powerful version of the 4.4-liter biturbo V8 found in the M550i xDrive. No official performance figures have been given, but early reports suggest the M5 could have as much as 600 horsepower (447 kilowatts) and 516 pound-feet (699 Newton-meters) of torque, with a 0 to 62 mile-per-hour (96 kilometer-per-hour) sprint of less than 3.5 seconds.

As far as other details are concerned, we’ll have to wait until the car makes its debut in full. Until then, head over to our colleagues at Motor1-UK, who got a chance to put the M5 prototype to the test a bit early.
