ECO PRO mode

WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.

The ECO PRO mode is activated using the driving experience switch. As default, the COMFORT program is set. To activate the ECO PRO mode: With terminal 15 towards, the driving experience switch must be moved towards COMFORT until ECO PRO appears in the instrument cluster (display of ECO PRO mode, see Owner's Handbook).

Intelligent control of energy management and the heating and air conditioning system forms the cornerstone of ECO PRO. A real life reduction in consumption of up to 10 % can be achieved.

Another accelerator pedal characteristic curve and altered shifting times of the automatic gearbox, the driver is supported in a consumption-optimized driving style.
Reduction of electrical loads such as seat heating, mirror heating and heated rear window.
More efficient control of the heater/air conditioning system
Number and length of possible phases for engine shutdown (MSA) are maximized.
Coasting: yet another consistent increase in efficiency
The shutdown of the combustion engine means this is possible not only at a standstill and in city traffic, but also when driving fast. If the combustion engine is not required, it can also be switched off by the hybrid drive while the vehicle is being driven. For this, the vehicle must be in the ECO PRO mode and the driver must not press the accelerator pedal. Up to a speed of 160 km/h, the combustion engine is then switched off and a separating clutch separates it from the rest of the drive train. The BMW ActiveHybrid subsequently runs silently and without emissions on the roadway without the influence of engine drag-torque. In order to ensure unrestricted operation of all safety functions and convenience functions, a small amount of the kinetic energy is converted into electric energy by recuperation.

In order to implement energy management that is even more strongly aligned to maximum efficiency, the range of functions of the Electrical Machine Electronics (EME) in the BMW ActiveHybrid have been extended to include an anticipatory analysis of the driving situation.

To this end, the Electrical Machine Electronics (EME) are networked with the series standard navigation system 'Professional'. This means it is possible to evaluate the data at an early stage that indicate a change in the outside conditions or in the driver request. In addition, the Electrical Machine Electronics (EME) also control operation of auxiliary components and convenience functions to achieve the greatest possible efficiency. The comprehensive networking enables the Electrical Machine Electronics to implement intelligent energy management and thus optimize the operating strategy of the complete vehicle under all conditions.

If, for example, a downward incline ahead is determined, all of the electric energy stored in the high-voltage battery unit can be used to support the drive. Reason: The high-voltage battery unit is recharged by the recuperation when the subsequently travels downhill. It is also possible to achieve an almost complete charge of the high-voltage battery unit in good time before reaching the destination to enable maximum electrical vehicle operation in the area of the destination.
