As soon as you switch to the ECO PRO Mode, everything is geared towards greater efficiency and depending on your individual driving style, this results in a reduction in fuel consumption of up to 20 per cent (according to an internal BMW fuel consumption study).
This mode optimises accelerator and transmission response as well as shift points, and intelligently adapts the heating/air conditioning strategy. The Control Display shows you which EfficientDynamics technologies are currently lowering your fuel consumption. You’ll also receive ECO PRO tips that relate to your current driving situation to help you boost efficiency even further.
A further 5% can be saved by using the additional coasting function (only with Steptronic transmission), preview assistant and ECO PRO Route (both only with Navigation system Professional) and the Active Cruise Control in the ECO PRO Mode.

The design of the vehicle is systematically geared to the BMW EfficientDynamics philosophy. In particular the aerodynamically optimised front apron and the underbody impress with their innovative new features that reduce drag and fuel consumption.
Embodying the BMW EfficientDynamics philosophy in a visible design feature is the front apron. The integrated Air Curtain guides the airstream along the front wheel housings via two vertical inlets. Once accelerated, the stream of air then forms a “curtain” around the outer sides of the wheels. Further, the Air Breather channels the airstream on the front wheels. These innovations reduce turbulence and drag, thus lowering fuel consumption. The smooth underbody lining and the engine compartment screening are further details that enable a significant enhancement in aerodynamics.


The Automatic Start/Stop function ensures that fuel is used only when your vehicle is on the move.
When your vehicle is stationary, for example at a red light or in a tailback, the Automatic Start/Stop function makes use of the energy-saving potential and switches off the engine as soon as the vehicle is in neutral and you have taken your foot off the clutch (manual transmission) or when you have operated the brake until the vehicle is at a standstill (Steptronic transmission).
The info display indicates that the function is active. As soon as you put your foot on the clutch (manual transmission) or take your foot off the brake (Steptronic transmission), the engine restarts automatically in an instant, allowing you to continue your journey quickly and smoothly.

Each time you brake, kinetic energy is released which, until recently, remained unused. Brake Energy Regeneration exploits this previously untapped potential by taking the energy produced whenever you brake or take your foot off the accelerator and converting it into electricity.
This energy is used to charge the battery. Thanks to this intelligent energy-management system, the alternator does not need to run permanently, which relieves strain on the generator. The result? Lower fuel consumption and higher performance – just as BMW EfficentDynamics intended.


The 8-speed Steptronic transmission and the 8-speed Steptronic Sport transmission enable much swifter gear shifts thanks to finely graduated gear ratios and short rev intervals. This ensures a combination of top-class comfort, lively dynamics and lower fuel consumption.
The 8-speed Steptronic transmission guarantees not only smoother gear changes and lower noise levels at high speeds – it also significantly reduces fuel consumption. The individual gears are more finely graduated and the transmission process is almost imperceptible. At the same time, the engine remains at the performance level that allows it to make optimum use of its power and efficiency. At high speeds, the additional gears reduce the revs, which leads to a reduction in both fuel consumption and engine noise.
