The driver’s driving habits are detected from the steering angle, engine speed, selected gear and braking conditions to constantly calculate the best driving mode for the vehicle. Actual driving conditions are monitored by each sensor. This electronic control system takes this information to constantly and automatically optimise traction and stability with a computer. Torque distribution between the front and rear wheels is optimised, torque distribution between left and right wheels is controlled when braking, and engine output also controlled in a flash, without hindering the sporty driving required by the driver, all to maintain a safe level of driving.
