Electric driving modes plus Driving Experience Control switch.
Drivers of the BMW 2 Series Active Tourer with eDrive can choose from three distinct electric driving modes. AUTO eDRIVE mode is the hybrid drive system’s default setting when setting off and ensures the electric motor and BMW TwinTurbo combustion engine work to optimum effect, as the battery’s charge level permits. In this mode the BMW 225xe can be driven at up to 80 km/h (50 mph) on electric power alone, and the electric energy summoned by the driver is displayed on the instrument cluster. If they request more power – e.g. when accelerating or at speeds above 80 km/h (50 mph) – the combustion engine is engaged automatically and without adversely affecting comfort. If the car’s speed drops back down below 80 km/h (50 mph), the combustion engine is decoupled and switched off, and the car reverts to electric power only. The car can even continue to run on electric power under light acceleration up to 55 km/h (34 mph) if the battery’s charge drops below seven per cent. If its charge falls to below three per cent, the combustion engine cuts in once again. Like the BMW i8 plug-in hybrid sports car, the BMW 225xe offers a MAX eDRIVE driving mode. At the touch of a button the car can use the electric drive system’s maximum output to drive emission-free up to a speed of 125 km/h (78 mph). The electric power can be metered out easily throughout the accelerator’s range without the combustion engine starting up (against the wishes of the driver). In this mode the BMW TwinPower Turbo petrol engine only comes into play when the accelerator’s kickdown threshold is passed. Total system output can be summoned up virtually instantaneously, if required. The three-cylinder engine can also be activated by pushing the
selector lever into “S”. Here, the drive system delivers maximum sports performance by making the full power of the electric motor and combustion engine combined (overboost included) available to the driver.Activating the SAVE BATTERY mode allows the driver to maintain the charge of the high-voltage battery to maximise the electric range for locally emissionfree driving later on in the journey. If SAVE BATTERY mode is activated when the battery’s charge is below 50 per cent, the charge is automatically increased to a maximum 50 per cent. If the high-voltage battery is running at over 50 per cent charge when this mode is engaged, its level of charge is maintained.
Driving Experience Control switch allows the drive system’s responses to be adjusted even more precisely to personal tastes.
The three eDrive modes can be matched in any configuration with the settings offered by the Driving Experience Control switch familiar from other BMW models. The SPORT, COMFORT and ECO PRO driving experience modes cover all areas of the car, adjusting the accelerator’s responses, the shift characteristics of the Steptronic transmission and the steering alike. For example, the drive system and chassis have sportier characteristics in SPORT mode than in the default COMFORT setting. ECO PRO mode adjusts the car’s energy and on-board climate management intelligently and switches off or reduces the performance of electric consumers like the exterior mirror and seat heating, for example. And in addition to changes to the accelerator responses and the optimisation of the gearshift program, the coasting function in ECO PRO mode enables further potential for energy saving. When linking up with the eDrive modes, the ECO PRO, COMFORT and SPORT Driving Experience Control modes address all the hybrid functions –such as electric driving, energy recuperation, electric assist and the boost function – in order to optimise the driving experience.
