The Golf TwinDrive project first introduced in July 2008 using the previous Golf V generation has been fitted to the new sixth generation Golf. Sponsored by the German government with double-digit millions, the research project aims to test the efficient use of renewable energy sources (wind, water and solar power) in transportation with 20 test vehicles using VW's next generation plug-in hybrid TwinDrive technology.
Capable of producing 176 hp (130 kW), the Golf TwinDrive uses an intelligent operating system which always chooses the optimal operating mode - individually tailored to the specific route and situation, so it always offers the most efficient combination of electric motor and combustion engine. Unlike typical hybrid drive systems which have an electric motor supplementing a combustion engine, "the exact opposite is true on the TwinDrive: here the diesel or gasoline engine supplements the E-motor," according to Prof. Dr. Martin Winterkorn. The TwinDrive places emphasis on a long range E-motor capable of 50 kilometers for city driving, while the combustion engine is for long range use.
No specific fuel efficiency figures have been provided yet, but VW gave an example of driving from Potsdam to the "Automobile Forum" in downtown Berlin and back - averaged over 100 kilometers - the Golf TwinDrive consumed just eight kilowatt-hours of electricity and 2.5 liters of fuel.
With Berlin test trials set to begin in 2009, VW expects to present initial vehicles as early as 2010.
