A clean car: a current concern
On 20 September 2006, the state of California launched prosecutions against six American and Japanese for "public nuisance" on the climate, because of the CO2 emissions from their vehicles. While a symbol of the country 4x4, which still refuses to ratify the Kyoto Protocol and its target of reducing by 75% the emission of greenhouse gases in transport by 2050. Still, the major manufacturers already reflect the different ways to make their vehicles cleaner. Each with his own car, the head in a clean car.
The car made its own path ...
... But the road is still long

2 - hybrid engines: a pragmatic solution, but limited
Between 1997 and 2005, Toyota has passed half a million to its Prius hybrid engine, combining an electric motor with a traditional combustion engine. The brand has two horns to double-up by 2010. GM and Ford are trying to replicate in the American market. But if the technology is developed, it also generates substantial incremental costs that some manufacturers are hesitant. PSA, for its part, made the leap to hybrid diesel.

3 - Biofuels: significant infrastructure needs
Made from plants, biofuels (bioethanol and biodiesel in particular) have the triple advantage of lowering the oil import bill for motorists and reduce CO2 emissions while offering opportunities to the agricultural sector. Among the preliminary development of green fuels: the development of engines adapted and the creation of distribution infrastructure. Brazil and Sweden - especially spurred by Saab - are ahead in this area. In France, the government announced the launch of green pumps throughout the territory.

4 - Hydrogen: pending fuel cell ...
Solution of medium and even long term, hydrogen is dependent on progress on the fuel cell. The engine, caused by the reaction of hydrogen produced by the cell and oxygen from the air, emits only water vapor. General Motors, very offensive on the niche, promises to produce one million vehicles a year by 2010. Ambitious ...

5 - LPG, CNG, electric battery: the alternatives
Despite its low success in France, LPG (liquefied petroleum gas) is the alternative fuel is more widely used across the world. He asked the adaptation of existing cars and a network of service stations. With the CNG (natural gas vehicle), full may also be made at home by installing a mini-station. Another alternative: all electric. In France, Serge Dassault and Vincent Bolloré capitalize on this technology, but the range of vehicles is still limited and prices of batteries deterrent.
