FEWER RESOURCES. MORE DRIVING PLEASURE.
BMW EfficientDynamics in the BMW 5 Series Gran Turismo.
The BMW 5 Series Gran Turismo 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.
ECO PRO MODE.
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).
The additional functions of coasting (with Steptronic transmission only), preview assistant and ECO PRO Route (both with Navigation system Professional only) enable another five per cent of savings potential. 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.
Another feature of the ECO PRO Mode is the coasting function in combination with Steptronic 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.
The preview assistant in conjunction with Navigation system Professional is an especially innovative highlight of ECO PRO Mode. Based on navigation data, it detects bends, built-up areas, roundabouts, T junctions, speed limits and motorway exits along the route and is able to give you tips in advance to enable you to reduce speed early on. The proactive driving assistant also efficiently controls the coasting function.
ECO PRO Route
ECO PRO Mode also includes ECO PRO Route which combines with the new generation of Navigation system Professional to draw on various parameters such as individual driving style as well as the current traffic situation and road conditions to calculate the most fuel-efficient route. The on-board computer displays your bonus mileage, in other words how many additional kilometres you have gained from using ECO PRO Mode.
BRAKE ENERGY REGENERATION.
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.
AUTOMATIC START/STOP FUNCTION.
The Automatic 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 Automatic Start/Stop function takes to save fuel by switching off the engine as soon as the car is idling and you have taken your foot off the clutch (manual transmission), or when you brake to a complete standstill (Steptronic transmission).
A signal in the Info Display indicates that the Automatic Stop/Start function is active. As soon as you shift into gear (manual transmission) or take your foot off the brake (Steptronic transmission), the engine switches itself back on in a split second so you can continue driving without delay.
The Automatic 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 heated/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 Automatic Start/Stop function can be switched off at any time with the push of a button.
