The plug-in hybrid system of the new BMW X1 xDrive 25e and the new BMW X2 xDrive25e consists of a 1.5 litre 3-cylinder petrol engine with BMW TwinPower Turbo Technology and an electric drive specially developed for this model. It is taken from the eDrive technology modular system of the BMW Group. The petrol engine mobilises a peak output of 92 kW/125 hp and a maximum torque of 220 Newton metres. It transfers its power to a 6-speed Steptronic transmission and drives the front wheels. The electric motor generates an output of 70 kW/95 hp and delivers 165 Nm of torque to the rear wheels via a single-speed transmission. This makes for a hybrid specific all-wheel drive, which gives both models a unique level of agility in their competitive fields delivering hallmark SAV and SAC driving pleasure. The highly responsive power delivery of the electric motor, which delivers its full torque spontaneously from standstill, enables the driver to react extremely quickly to changing driving conditions. In addition, the position of the electric motor above the rear axle contributes to the harmoniously balanced axle load distribution of the new BMW X1 xDrive25e and the new BMW X2 xDrive25e. In conjunction with the intelligently controlled interaction between the two power units, it provides maximum driving stability, ride comfort and dynamic response.
The latest-generation lithium-ion battery has a gross energy content of 10 kWh. This allows for an electrically powered range of between 54 and 57 kilometres in the BMW X1 xDrive25e (between 55 and 57 kilometres in the new BMW X2 xDrive25e). The high-voltage battery can be charged at conventional household sockets using the standard-equipment charging cable. An empty battery can be fully charged in around five hours in this way. It only takes 3.8 hours for the battery to reach 80 percent of its total capacity. Using a BMW i Wallbox, the relevant charging operation from 0 to 100 percent takes less than 3.2 hours. 80 percent of total capacity is already reached after 2.4 hours. The charging socket is located under a separate flap on the front left side wall of the car.
The positioning of the high-voltage battery underneath the rear seats not only leads to a very low centre of gravity, which optimises the agility of the BMW X1 xDrive25 and the new BMW X2 xDrive25e, but also to a slightly reduced transport capacity compared to the conventionally powered compact model variants. The luggage compartment volume is fully available in primary use. In the new BMW X1 xDrive25e luggage compartment capacity is 450 litres. With a standard split of 40: 20: 40, the folding backrests enable this to be increased to 1,470 litres. A trailer tow hitch with detachable ballhead is optionally available for the new BMW X1 xDrive25e. The maximum trailer load is 750 kilograms.
