Volkswagen has revealed a new concept called the Golf Twin Drive expected to launch in 2010. The Twin Drive is a plug-in electric hybrid that uses a powerful 82-hp electric motor and a 2.0L turbodiesel engine.

The electric motor, powered by llithium-ion batteries charged from exisiting power outlets can will allow the car to travel 31 miles without releasing any emission, before the diesel engine will take over.

Volkswagen is developing the Twin Drive system with eight German partners and is planning a trial fleet of 20 Golfs with the hybrid system in 2010 to test the real world capabilities and viability of the next-generation system.
