ECO PRO Mode.
ECO PRO Mode helps drivers to reduce their fuel consumption by up to 20 per cent, depending on their driving style – according to an internal BMW fuel consumption study.
Further savings potential can be achieved through coasting (with 8-speed Steptronic transmission only), Route-Ahead Assistant and ECO PRO Route (both with Navigation System Professional only).
The coasting function disconnects the drive train from the engine and the car coasts without the engine running, "sailing". This occurs when the driver releases the accelerator between 50 and 160 km/h without braking, and the Route-Ahead Assistant doesn't foresee a need to adjust the speed.
When used with Active Cruise Control, in ECO PRO Mode the vehicle accelerates up to the desired speed more efficiently after braking.
Based on data from the navigation system, the Route-Ahead Assistant recognises curves, built-up areas, speed limits and motorway exits, and gives the driver tips in advance about when to stop accelerating.
Depending on the traffic situation, the driver's behaviour and road conditions, ECO PRO Route displays the most efficient course to take. The on-board computer shows the percentage of fuel that can be saved by taking the ECO PRO Route.
