Innovative environmental technology
Electricity is very well-suited as a power source for cars. An electric motor has a high efficiency rating and consumes roughly one-fifth the energy needed to power an engine that runs on fossil fuels. The purchase price of the plug-in hybrids will be higher than that of cars with conventional technology. Batteries are still expensive but with the car running on electricity, its fuel costs will be cut to roughly one-third compared with diesel power.

Vattenfall will offer customers the opportunity to sign an agreement for renewable electricity sourced specifically from windpower or hydropower, as an alternative to the regular mix of electricity sources. Lars G Josefsson sees many benefits from chargeable plug-in hybrids, even in cases where the electricity does not come from renewable energy sources.
"Through electric power, we avoid the emissions from each individual car. Instead of petrol or diesel, the energy is derived from a few large power sources and Vattenfall is working hard to eliminate carbon dioxide emissions from all electricity production. In Sweden, virtually all Vattenfall's electricity production is emission-free," explains Lars G Josefsson.
The plug-in hybrid cars will be driven by a powerful electric motor fuelled by a lithium-ion battery. 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.
"Most car journeys are short trips, for instance to and from work. We will be able to offer a product that fulfils this transportation need. In order to cover longer distances as well, the car will also be equipped with one of Volvo's fuel-efficient diesel engines," says Stephen Odell.
Demonstration cars on show this summer
In the summer of 2009, three Volvo V70 demonstration cars will be presented. The demonstration cars will be used to gather information about the wishes and demands that drivers may have on the new technology, to determine their driving habits and to establish how they want to charge their cars. 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 cars that are planned to go into series production in 2012 will feature somewhat different technology, but the launch of the demonstration vehicles is a step towards series-producing plug-in hybrid cars specifically tailored to market needs.
