On its behalf Vattenfall will, among other things, test various concepts for high-speed home charging and also for charging stations in public places, where owners pay to fuel with electricity instead of petrol or diesel.

The prototype V70 Plug-in Hybrids combine a front-mounted diesel engine that is designed to run on renewable synthetic fuels and will meet forthcoming extremely stringent exhaust regulations, with a rear-mounted electric motor powered by a 11.3 kWh Li-ion battery pack. The battery takes about five hours to charge from a standard wall socket, and the battery is also charged every time the car's brakes are applied.

Volvo said that the cars that are planned to go into series production in 2012 will feature somewhat different technology, but claimed that the launch of the prototype vehicles is a step towards series-producing plug-in hybrid cars specifically tailored to market needs.

The automaker claims that while the purchase price of the plug-in hybrids will be higher than that of conventional cars, its fuel costs will be cut to roughly one-third compared with diesel power.

"We are investing in an industrial joint venture to series-produce plug-in hybrid cars in Sweden in 2012, cars that can be powered by both electricity and diesel." says Stephen Odell, President and CEO of Volvo Cars. "This is an important business development for us and our partnership with Vattenfall allows us to take a giant step toward offering our customers cars with an even smaller environmental footprint."
