A central locking mechanism can send torque to the wheel with the most traction.
Like the BMW X6, the Turbo X uses an active rear differential to send torque to its outside rear wheel in a corner, helping to steer the car into the bend.
You can have your RX with front drive or with a newly simplified all-wheel-drive system that relies on the electronics of the vehicle stability control to send torque where it is needed on slippery surfaces.
A Sport package adds firmer suspension settings, 20-inch wheels, handsome diamond-stitched leather seats, variable-ratio steering and a rear-axle differential that sends torque from side to side for better handling.
It's not a hub loader; these motors are mounted in the body and each one sends torque out to each wheel for precise control.
The mechanism for sending extra torque to a wheel that needs it -- if a loss of traction is detected -- differs by model.
Both have an electronic locking differential in front and rear axles that limit how much each wheel can spin, sending more torque to a wheel on the other side that has traction.
The engine also begins sending more torque to the rear axle.
This all-wheel-drive system, which combines planetary gearsets and electronic multiplate clutches, monitors g-forces and sends extra torque to the outside rear wheel to help rotate the BMW through turns.
The Golf R Estate's highly competent 4WD set-up can send the torque to the front or rear wheels, and understeer is brought under control by the XDS+ system, which brakes the inside wheels under hard cornering.
