4 Operation - swivel rear axle

A swivel rear axle is an axle that responds to the rotation of the front wheels. The function changes depending on the speed. At speeds up to 60 km/h, the rear wheels turn in the opposite direction to the front wheels, with a maximum rear wheel turn of 3,5°, reducing the turning radius from 11,16 m to 10,10 m (Laguna). The main advantage is the need to turn the steering wheel less. On the other hand, at higher speeds, the rear wheels turn the same way as the front wheels. The maximum turn in this case is 2° and its purpose is to stabilize and make the vehicle more agile.

In the event of a crisis management maneuver, the rear wheels can be turned in the same direction as the front wheels by up to 3,5 °. This reduces the risk of rear wheel skidding and allows the driver to drive in a straight line easier and faster. The ESP stabilization system is also tuned to this response, which, together with ABS, helps to recognize such evasive maneuvers. The system works with information from the steering column sensor, ABS, ESP sensors and, based on these data, the required angle of rotation of the rear wheels is calculated. The electric drive then presses on the steering rods of the rear axle and causes the required rotation of the rear wheels. The system is manufactured by the Japanese company Aisin.
