ECO PRO Mode.
The ECO PRO Mode helps drivers reduce their fuel consumption by up to 20 percent, depending on their driving style.
The additional functions of coasting (only available with eight-speed Steptronic transmission), Route-Ahead Assistant (with Navigation System Professional only) and ECO PRO Route (with Navigation System Professional and Business only) can reduce consumption by a further 5 percent.
The coasting function decouples the powertrain from the engine and the vehicle rolls without the transmission. The car then "coasts" when the driver takes the foot from the gas between 50 and 160 km/h, does not apply the brakes, and the Route-Ahead Assistant does not adjust the speed.
In combination with the Active Cruise Control, the vehicle also accelerates more efficiently after braking when in ECO PRO Mode.
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.
