ALL4 is a permanent all-wheel drive system , which is used on MINI vehicles. It optimizes traction, stability and handling in all weather and road conditions.
How it works
Engine torque is transmitted through a bevel gear and cardan shaft to the gearbox, and then to the center electromagnetic differential. The differential ensures an even distribution of torque between the two axles. When driving on flat roads, up to 50% of the torque is sent to the rear axle. If the wheels lose traction, the car can also be driven via rear-wheel drive (RWD). When driving on the highway, engine torque is redistributed to the front wheels, reducing fuel consumption.
The ALL4 system is managed by Dynamic Stability Control. Signals from the steering angle sensor, brake pressure sensor, wheel speed sensor and yaw rate sensor are analyzed in fractions of a second. This data is taken into account by the system and the torque distribution between the axles is precisely adjusted. As a result, this ensures perfect stability and maximum driving safety when manoeuvring.
