Reaching new heights with great efficiency: An extremely efficient Drive concept is a hallmark of the plug-in hybrid. This basically consists of a combustion engine at the front of the vehicle and an electric motor on the rear axle. Depending on the situation and the charge level of the high-voltage battery, both are capable of powering the plug-in hybrid either individually or together. When only the combustion engine is active, the drive power is delivered via the front wheels. While the electric motor, for its part, delivers power to the rear wheels. According to the situation, therefore, the BMW 225xe Plug-in hybrid Active Tourer becomes a BMW with xDrive.
