The Predictive Powertrain Control system which now comes as standard provides a simple means of saving even more fuel.On motorways, A and B roads and city streets alike.
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.
Automated anticipatory driving.
On a steep hill, ahead of a hilltop, coasting down a hill, in dips or on the flat – Predictive Powertrain Control recognises impending driving situations in good time and takes anticipatory action.
To this end, Predictive Powertrain Control continually monitors the vehicle's kinetic energy and uses it ahead of hilltops or on the flat for EcoRoll phases. This reduces engine drag losses and saves fuel.
The system also adapts shift sequences to the impending driving situation, applying less gear changes and larger gear steps. This also helps to reduce fuel consumption.
Economy driving program.
The "economy" drive program is optimised for use in long-distance haulage and supports an economical driving style.
Advantages at a glance.
Up to 5% less fuel consumption as standard
Identification of the course of the road, such as uphill and downhill gradients, junctions and roundabouts
Optimisation of shift points, gear selection and the cruise-control speed setting
Optimum use of the system using traffic-dependent setting and Traffic Sign Assist
Now usable not only on motorways, but on A and B roads as well
