The system, now fitted as standard, integrates an additional mode into the automatic transmission system that adapts to the topography of the road ahead, enabling fuel savings of up to 5 % in conjunction with the precisely matched driving strategy. The new extended functions of Predictive Powertrain Control now enable use of the system's benefits on A and B roads, too. In addition to the satellite-based positioning system and precise 3D maps, Predictive Powertrain Control also uses the Traffic Sign Assist feature.
In addition to the course of the road with uphill and downhill gradients ahead, the system also identifies junctions, roundabouts and traffic signs integrated in 3D maps. On the basis of this data, Predictive Powertrain Control optimises shift points, gear steps and the set cruise control speed. What's more: the vehicle's kinetic energy is used to avoid unnecessary acceleration, shifting or braking. This means that cruise control can be used in virtually all driving situations. This relieves the driver's workload and contributes to a fuel-efficient driving style on A and B roads, too. Predictive Powertrain Control can be used in conjunction with cruise control at speeds between 25 and 90 km/h.
