The ECO PRO mode helps drivers reduce their fuel consumption by up to 20 percent, depending on their driving style – according to an internal BMW fuel consumption study. The "coasting" function, the route-ahead assist and ECO PRO route make it possible to save a further 5 percent.
The coasting function decouples the drive train from the engine and the vehicle rolls without any engine resistance. The car "coasts" when the driver takes their foot off the accelerator between 50 and 160 km/h and does not apply the brakes. If needed, the route-ahead assist can intelligently suppress coasting.
Based on data from the navigation system, the route-ahead assist recognises speed limits, built-up areas, bends, traffic circles, turns and highway exits, and advises the driver to stop accelerating at just the right moment.
ECO PRO route shows the most efficient route based on the traffic situation, driving style and local conditions. The on-board computer displays the percentage of fuel that can be saved by driving along the route selected by ECO PRO route.
