Volkswagen unveils Golf Twin Drive plug-in hybrid prototype

Volkswagen has unveiled a Golf Twin Drive in its home-country of Germany, which is the company's first plug-in hybrid capable of driving up to 30 miles on electricity alone. The electric motor is rated at 82 horsepower, and when its energy is spent, a 122hp 2.0-liter turbodiesel engine kicks in to extend the range.

The usual tricks to extend the battery life are accounted for, including an engine shutdown system when stopped and regenerative brakes. On electricity alone, the Golf can reach a top speed of about 75 mph, as per Motor Authority reports. Supplying its energy are lithium-ion batteries, that feature a fast-charging capability from a household power outlet.

VW will launch a fleet of 20 Twin Drive Golfs in Germany for the government's use, to research the zero-emissions vehicle. To help it make the claim, the electricity needed to recharge the Twin Drive's batteries will be generated by wind and hydro generating stations.
