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 assistant and ECO PRO route make it possible to save a further five percent.
The coasting function (only available in conjunction with 8-speed Steptronic transmission) decouples the drive train from the engine and the vehicle rolls (or "coasts") without any propulsion when the driver takes the foot from the gas at speeds of between 50 and 160 km/h, does not apply the brakes, and the route-ahead assistant does not adjust the speed.
Based on data from the navigation system, the route-ahead assistant (only available in conjunction with navigation system Professional recognizes curves, built-up areas, speed limits and motorway exits, and gives the driver tips in advance about when to stop accelerating.
ECO PRO route (only available in conjunction with navigation system Professional or navigation system Business) shows the most efficient route based on the traffic situation, driving style and road conditions. The on-board computer displays the percentage of fuel that can be saved by driving along the route selected by ECO PRO route.
