BMW present the BMW 5-Series ActiveHybrid Concept, this is a sedan concept of a dynamic, efficient and innovative. The drivetrain technology featured in the BMW 5-Series ActiveHybrid Concept allows all-electric, zero-emission motoring in city traffic.
The drive system featured in the BMW 5-Series ActiveHybrid Concept consists of a straight-six gasoline engine with TwinPower Turbo technology, eight-speed automatic transmission, and electric drive. Integration of BMW ActiveHybrid technology in a sedan already extremely efficient with its “conventional” combustion engine reduces both fuel consumption and emissions. Drawing its energy from a high-voltage battery at the back of the car, the electric motor develops maximum output of 40 kW. In addition, an automatic clutch connects the gasoline engine and the electric motors.
An integrated control unit permanently analyses the charge status of the high-voltage battery and controls both the battery charge process by way of Brake Energy Regeneration and the system cooling process. Apart from the electric motor, the high-voltage battery also delivers electric power to the car’s on-board network. Can use to climate control activated whenever required by a remote control function to cool down the car’s interior significantly even before starting the engine. Convenient use of the all-electric driving mode and the Auto Start Stop function is likewise guaranteed in this way, with all electrical functions such as the audio system, climate control or navigation remaining fully available even with the combustion engine switched off.
