BMW EfficientDynamics in the BMW 5 Series Sedan.

The BMW 5 Series Sedan also leads the way in efficiency. Every single BMW 5 Series has a package of measures and technologies from BMW EfficientDynamics, which significantly lowers consumption while decreasing toxic emissions – for even more driving pleasure.

BMW 520d.

The BMW TwinPower Turbo 4-cylinder diesel engine of the BMW 520d produces an exceptional 135 kW (184 hp) performance from its 2.0 litre capacity.

Its combination of CommonRail direct injection and a turbocharger with variable turbine geometry yields a top speed of 231 km/h and acceleration from 0 to 100 km/h in 7.9 seconds, with a torque of 380 Nm at 1,750 to 2,750 rpm. The efficient average fuel consumption: 22.2 km/l at a CO2 emissions level of 129 g/km.

The figures for fuel consumption and CO2 emissions apply in connection with the wheel and tyre size selected.

Further information about the official fuel consumption and the official specific CO2 emissions for new passenger automobiles can be found in the 'New Passenger Vehicle Fuel Consumption and CO2 Emission Guidelines', which are available free of charge at all sales outlets and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, 73760 Ostfildern, Germany.


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 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.

  • Coasting

    Another feature of the ECO PRO Mode is the coasting function in combination with automatic transmission: if within a speed range of 50–160 km/h the driver takes their foot off the accelerator and does not brake, the system disconnects the engine and the car coasts – i.e. rolls without engine power.

  • ECO PRO Route

    ECO PRO Mode also displays your bonus mileage, in other words how many additional kilometres you have gained from using ECO PRO Mode.


The entire vehicle design is testament to the BMW EfficientDynamics philosophy. The optimised, aerodynamic front apron and undercarriage feature innovative improvements that reduce air resistance and fuel consumption.

The entire front section embodies the BMW EfficientDynamics philosophy, including the newly designed front apron. The optimised design of the cooling air inlets also contributes to improved aerodynamics - thereby reducing air resistance. The same applies to the wheel arches, which are specially designed to reduce air swirl.

The flat undercarriage cover, which also shields the engine compartment, is an additional detail that greatly improves the car’s aerodynamics. This new cover is not only advantageous in terms of aerodynamics: it also improves sound insulation and provides greater protection from rust.


Every time you brake, kinetic energy is generated and until recently this energy went unused. Brake Energy Regeneration takes advantage of this long-overlooked potential. It harnesses the coasting energy that is generated whenever you brake or take your foot off the accelerator and turns it into electricity.

This electricity is then used to charge the car battery. The intelligent energy management system means that the alternator no longer needs to run permanently, which reduces the strain on the generator. The result is reduced fuel consumption and increased performance – classic BMW EfficientDynamics.


The Auto Start-Stop function makes sure that fuel is only used when your car is actually driving. Whilst waiting at traffic lights or in stop-and-go traffic, the Auto Start-Stop function takes to save fuel by switching off the engine as soon as the car is idling and when you brake to a complete standstill.

A signal in the Info Display indicates that the Auto Stop-Start function is active. As soon as you take your foot off the brake, the engine switches itself back on in a split second so you can continue driving without delay.

The Auto Start-Stop function never compromises driving comfort and safety, as it remains inactive if the engine has not reached its ideal running temperature, the interior has not yet been sufficiently cooled, if the battery level is too low or if you are turning the steering wheel. A central control unit restarts the engine if required, even when the car is at a standstill. For example, if the car starts to roll forward or if the windscreen becomes foggy. The Auto Start-Stop function can be switched off at any time with the push of a button.
