The system integrates a driving style optimised for the route topography into the operation of the automatic transmission and, in conjunction with the precisely coordinated shift strategy, allows fuel savings of up to 5% to be achieved. Using satellite-based positioning technology and maps, Predictive Powertrain Control (PPC) identifies the course of the road and any downhill and uphill stretches ahead. The data provide the basis for the optimisation of the shift points, gear steps and the set cruise control speed. The kinetic energy of the vehicle is used as far as possible to avoid unnecessary acceleration, shifting or braking. PPC knows some 350,000 kilometres (95 %) of European trunk roads and can be used at speeds between 25 and 90 km/h.

Predictive Powertrain Control.
Advantages at a glance.
- Predictive Powertrain Control: fuel consumption reduced by as much as 5% thanks to a driving style that adapts to the topography of the road ahead
- 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 via traffic-dependent setting with adjustable upper and lower hysteresis plus dedicated Traffic Sign Assist
- Available in Western and Eastern Europe on motorways and highways with PPC coverage
Topography-oriented driving style.
Predictive Powertrain Control uses digital 3D road maps and GPS information to generate an electronic horizon which is employed to optimise shift points, gear selection and the set cruise control speed in anticipatory mode. In this way, a driving style adapted to the given topography which will generally be beyond the capabilities even of experienced drivers can be integrated into the automated system, resulting in additional fuel savings of up to 5%.
