And for the first time air conditioning and ventilation can remain operating even with the engine switched off.

The BMW ActiveHybrid X6 is a full-hybrid model. The drive system is a 300 kW/407 hp V8 with BMW TwinPower turbo technology and two electric synchronous motors developing 67 kW/91 hp and 63 kW/86 hp.

Maximum system output is 357 kW/485 hp and peak torque is 780 Nm.The sedan accelerates to 100 km/h in 5.6 seconds. Its top speed is limited electronically to 236 km/h.

The recuperation capacity of the BMW ActiveHybrid X6 is about 25 times greater than the power now developed by brake energy regeneration in its standard form.

The BMW's first full-hybrid model is able to drive entirely under electric power up to speed of 60 km/h. The electric motors draw their energy from a NiMH high-performance battery fitted beneath the floor of the luggage compartment that also supplies electric power to the car's on-board network.
