BMW EfficientDynamics has been synonymous with innovative consumption improvement measures for generations of vehicles. It is therefore a key element of the BMW Sustainability Strategy. Key factors affecting greater driving enjoyment coupled with lower consumption include lightweight construction through the use of an optimised material mix with high-strength steels along with aluminium doors and flaps.

Moreover, favourable aerodynamic properties with a drag coefficient value of 0.24 increase efficiency through the use of aerodynamic wheels, intelligent air flap control and a smooth vehicle underbody. This optimises the consumption of the BMW 520i to 6.4–5.7 l/100 km. 

But you, the driver, as ever, are also a crucial influencing factor. You can save fuel through an efficient driving style, depending on the route and traffic situation.
