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 additional functions, coasting (with automatic transmission only), Route-Ahead Assistant and ECO PRO Route (both with Professional Navigation System only), deliver even more savings potential.
This occurs as soon as the driver takes his or her foot off the accelerator between the speeds of 31 and 100 mph without braking and the Route-Ahead Assistant does not detect any change in the speed limit.
Using data from the navigation system, the Route-Ahead Assistant is able to recognise curves, built-up areas, speed limits and motorway exits - it then gives the driver tips to slow down in advance.
Depending on your driving, the traffic and the road conditions, the ECO PRO Route displays the most efficient route. The on-board computer shows what percentage of fuel can be saved by using the ECO PRO Route.
