Volkswagen – in cooperation with six project partners and the German Ministry of the Environment – presented the current status of the 'Fleet study in electric mobility' initiated in July 2008. The primary goal of the project, which runs until June 2012, is to consistently use renewable energy sources for PHEVs – 20 Golf Variant twïnDRIVE cars.


The Golf Variant twïnDRIVE enables distances of up to 57km (35 miles) on pure electric power; a small range extending engine provides for a total range of about 900km (560 miles).

VW chairman Martin Winterkorn says the 'Fleet study in electric mobility' has become more important with the German federal government’s mandatory exit from nuclear energy.

According to plans by the federal government, the number of pure EVs will reach one million units in Germany alone by 2020, which must be operated from renewable energy sources to attain significant progress in environmental protection. Over 16% of Germany’s current power demand is already covered by renewable energy sources, and plans are afoot to extend this share to 30% by 2020. The PHEV fleet study is analysing the usage behaviour of drivers of cars with electrical charging, electric load control and intelligent strategies in the charging process. In addition, a scenario is being tested in which some daily peak electrical demand might be buffered by the cars’ lithium-ion batteries.


Volkswagen AG aims to launch several PHEVs in 2013/2014, to supplement the group’s hybrid models from Audi, Porsche and Volkswagen, as well as the pure electric vehicles that will also be launched from 2013. Winterkorn comments: “Over the mid-term, the plug-in hybrid offers great potential here, because it unites the best of two worlds in one vehicle.”

The 'Fleet study in electric mobility' is being conducted by six project partners under Volkswagen AG’s leadership: the utility E.ON, the Fraunhofer Gesellschaft ISIT (involved with battery systems and new battery chemistry development), Heidelberger Institute for Energy and Environmental Research, the German Aerospace Centre DLR (undertaking analysis and forecasting traffic scenarios) and the Westphalian Wilhelm University in Münster (developing methodologies and laboratory testing of battery cells).
