Progressive though the function of DISTRONIC PLUS is, it is simple to explain: the system brakes when necessary. And it accelerates again to a pre-set desired speed as soon as that is possible. Steer Assist also helps the driver to keep in lane. With the help of a stereo camera the system utilises clearly visible roadside markings or, at low speeds, utilises the vehicle in front as a point of reference. On straight roads and even in slight bends, it generates steering torque which can help to keep the vehicle in the centre of the lane. DISTRONIC PLUS with Steer Assist is available for the C-, E-, V- and S-Class and also for the CLS, GLC, GLE and the Mercedes-AMG GT. However, the system is only one of about a dozen examples for extending and sharpening the “senses” of the increasingly intelligent vehicle.
