Lurking under the bonnet of the new BMW M5 is the latest version of the 4.4‑litre V8 engine featuring M TwinPower Turbo technology. The further improved high-revving engine outperforms its predecessor in terms of power output (more than 600 horsepower) and torque.
The principal hardware components of M xDrive are based on those of the BMW xDrive intelligent all-wheel-drive system and the Active M Differential, while the M-specific driving dynamics control software ensures innovative deployment. The drivetrain has been reinforced for greater rigidity and strength to factor in the high torque, rear-biased configuration and 2WD option. While the transfer case splits a portion of the engine’s drive between the front and rear wheels in a smoothly adjustable ratio (depending on requirements), the Active M Differential is responsible for then distributing the drive between the rear wheels. This active control element is part of the M xDrive system’s functionality and its locking effect can be varied between zero and 100 per cent, as the situation demands. This ensures enhanced traction, agility and handling stability when the car is being driven in a very sporty manner or on roads with differing levels of grip – i.e. exactly when it is needed. Since M xDrive includes M-specific dynamics control capability, stabilising interventions from the DSC system are only required in extreme situations. And so the engine’s huge power can be converted into propulsive force with virtually zero losses. The upshot of all this is that the new BMW M5 can be guided with even greater precision and directional accuracy, responds sensitively and directly to the driver’s inputs and thus requires few steering corrections when driving at the limit.
Every time the engine is started, the BMW M5 defaults to 4WD mode with DSC on.
With DSC deactivated, there is a choice of three modes (4WD, 4WD Sport and 2WD).
