The M5 sport sedan appeared in 1984 and is now in its sixth generation for which BMW reserves a nice surprise, at least to those who found that their sedan had become too wise with the xDrive all-wheel drive.
For these and the M5, BMW has concocted a new transmission, the M xDrive.
As the chairman of the board of directors Frank van Meel explains, “the new M5 can be steered with infallible precision both on the track and on the road – and under various weather conditions”.
The M xDrive transmission can be adjusted to take maximum advantage of the steering by actuating the rear wheels. The front pair only comes into play when the rear wheels can not transmit more power to the road and additional traction is required.
Purists have the choice of using only the rear driving wheels by completely disabling the integral transmission mechanics.
Up to five presets based on combinations of DSC modes are available to the driver: (DSC on, MDM – M Dynamic Mode, DSC off) and M xDrive modes (4WD, 4WD Sport, 2WD).
V8 4.4 liters biturbo (M TwinPower Turbo)
Upstream of the transmission, BMW retains its 4.4-liter V8 inflated by two turbochargers. For the new M5, the new M5 is equipped with higher pressure injectors, new turbines, more powerful lubrication and cooling, and a carefully tuned exhaust system to “sing” well to the purist’s ears. The eight-speed Steptronic M-box manages engine rpm.
For precise specifications of this V8, it will be necessary to wait until the Motor Show of Frankfurt, in Germany, in September. This explains among other things the camouflage of the M5 in photos.
