The first fully-electric BMW xDrive system can now be experienced on the road in the BMW iX and the BMW i4 M50

The first fully-electric BMW xDrive system can now be experienced on the road in the BMW iX and the BMW i4 M50The first fully-electric BMW xDrive system is faster, more precise, and more efficient, and can now be experienced on the road. It makes its debut in the BMW iX and the BMW i4 M50. Two engines, four driven wheels, and a globally unique drive torque control system ensure optimal traction, driving stability, and dynamics in every situation.

Like all BMW iX vehicle types, the fully electric Gran Coupé from BMW M GmbH is powered by an engine on both the front and rear axles. This creates an axle-parallel all-wheel drive without a mechanical connection between the front and rear wheels. The interaction of the two engines is optimized by an innovative and globally unique drive torque control system. The electric BMW xDrive system thus ensures the ideal form of power transmission in every driving situation – combined with a typical BMW driving experience.

The fully electric BMW xDrive system makes it possible to transform outstanding drive power, expressed for example in the BMW i4 M50 with a system output of up to 400 kW/544 hp and a maximum torque of 795 Nm, into superior driving dynamics. This requires precise distribution of the drive torque. This is ensured by linking the DSC (driving stability control) system with the all-wheel drive-specific version of the actuator contiguous wheel slip limitation and the Combined Charging Unit (CCU), whose highly integrated range of functions for the first time includes both charging and drive electronics. The intelligent networking of all systems makes it possible to distribute the drive torque requested by the driver between the two engines in such a way that traction and driving stability, dynamics and efficiency are guaranteed to an optimum extent in the respective driving situation.

During driving off and accelerating, the desired drive torque is distributed between both engines by the CCU to provide optimised traction. In addition to the road friction values and the driver's choice, the electric BMW xDrive and actuator contiguous wheel slip limitation also take into account environmental parameters such as wind, uphill or downhill gradients, the vehicle settings of the My Modes and the DTC, as well as the dynamic axle-load distribution, which provides more weight and better power transmission to the rear axle during acceleration. Due to the direct integration of actuator contiguous wheel slip limitation into the drive torque control system of the CCU, long signal paths to the driving stability control system are eliminated, meaning that interventions can be performed at a speed that is up to 10 times higher and in a particularly precise dosage. This ensures unwavering directional stability of the vehicle even during extremely dynamic acceleration maneuvers. Full all-wheel drive functionality is available at all times.

In coasting and braking phases, both engines can feed energy back into the high-voltage battery by means of a generator function. This makes a significantly higher recuperation performance possible than just one motor. The fully electric BMW xDrive system also makes it possible to control these energy recovery processes in such a way as to ensure maximum driving stability and efficiency at all times. The system is designed so that the more powerful engine on the rear axle also takes on the main role in recovering energy. In curves and in adverse road conditions, on the other hand, a higher proportion of energy recovery performance is provided by the front engine.

Just like the drive torque, the energy recovery torque can also be divided quickly and precisely between the two engines. In addition, the intelligently networked drive torque control system ensures that a stable driving condition is also guaranteed during deceleration processes. The slip control set by DSC helps to prevent unstable driving conditions caused by excessive braking recovery. The transition from deceleration through recovery to the intervention of the hydraulic braking system is not perceptible to the driver. The integrated braking system also contributes to this, providing a constant pedal feel at all times.
