Having power is one thing, making intelligent use of it is quite another. And that is exactly what the xDrive all-wheel drive system does in the BMW Security Plus. However demanding the situation, xDrive will adapt to any surface to ensure maximum traction at all times. So you stay in total control of your vehicle. By measuring parameters such as steering angle and the speed of the individual wheels, xDrive is able to recognise when the vehicle is threatening to under or oversteer, and react immediately. An electronic clutch adjusts the division of engine torque between the two axles in a fraction of a second, so as to ensure power always goes to the wheels with the most grip. The result is a gripping drive, in every sense.
The BMW all-wheel drive system, xDrive, ensures your BMW X5 has the best possible traction at all times, enhancing agility and keeping you safely on track, even on fast bends. Under normal circumstances, it distributes driver power between the front and rear axles in a 40:60 ratio, and changes this figure variably when the road surface or overall driving conditions change.
When parking, the system reacts to the need for high manoeuvrability at low speed by opening the clutch completely so the powertrain functions optimally. BMW xDrive is regulated by Dynamic Stability Control (DSC) and uses information from the latter system’s sensors to monitor road conditions. In addition, brake force courtesy of DSC is used when there is traction difference between the two sides of the vehicle and wheel spin is likely.
