Besides the 3-Series Plug-In Hybrid Prototype, BMW also showed a new prototype based on the 5-Series GT that features Power eDrive plus TwinPower Turbo technology. According to BMW, this technology aims to increase overall efficiency and the dynamism of upcoming hybrid vehicles.
Power eDrive electric drive system will deliver approximately two thirds of the vehicle’s combined output, while the remaining third will be generated by the TwinPower Turbo internal combustion engine.
What’s surprising is that the future hybrid system will deliver combined outputs in excess of 670 hp (500 kW) and up to 1,015 Nm (750 lb-ft) of torque, while the capacity of the lithium-ion batteries will be up to 20 kilowatt hours.
The electric range will also be increased to up to 100 km (62 miles). On the upcoming plug-in hybrid concepts, the main source of power for everyday driving will be the electric motor and will drive the rear wheels, while the second electric motor will drive the front wheels.
This means that the vehicles will get an all-electric road-coupled all-wheel-drive system. Meanwhile, the internal combustion engine will be also be sued to power the front wheels.
