April 9, 2008 Renault is set to introduce its new electronically-controlled Active Drive chassis with four-wheel steering next month in new GT versions of the Laguna Hatch and Sport Tourer. Four-wheel steering systems of the 1980s were essentially mechanical, with the wheels linked at pre-determined angles to make up for a vehicle's tendency to understeer. Such systems were gradually superseded by the advent of ESP. In recent times some manufacturers have begun developing electrically- and even hydraulically-operated actuators, enabling handling to be fine-tuned even further.
