BMW

The BMW Concept X6 ActiveHybrid is the concept vehicle of BMWs first full-hybrid vehicle and was revealed at the Internationale Automobil-Ausstellung Frankfurt in September 2007. BMWs first mild-hybrid BMW Concept 7 Series ActiveHybrid was revealed at the Paris Motor Show in October 2008. Both cars will make their market debuts at the end of 2009  and can drive in electrical mode at low speeds.
The BMW Concept X6 ActiveHybrid uses the V8 Twin Turbo with High Precision Injection that powers the BMW X6 xDrive50i.
A defining feature of the BMW Concept X6 ActiveHybrid is its Two-Mode active transmission, an innovative technology that controls the interplay of the electrical motors and the internal combustion engine. The car can operate in two modes: mode 1 delivers high torque when pulling away from a standing start and at low speeds, while mode 2 is suited for higher speeds. The result is that the car always uses the available power resources in the most efficient possible way, whatever speed it is travelling at.
