PSA/Peugeot-Citroen plans to introduce vehicles with engines that automatically shut down when the car is stalled in traffic.
The "stop and go" system will be introduced within 20 months on some vehicles, according to a PSA executive who asked not be named.
The system turns off the engine when the car stops - for example in heavy traffic or at traffic lights. The engine restarts when the driver presses the accelerator pedal. PSA calls its system a "mini hybrid" application and says it reduces CO2 emissions by 5 to 7 percent.
In addition, PSA will launch a production version of its DYNActive starter-alternator between 2005 and 2007. The new device replaces the current alternator and starter with a single component. PSA also calls DYNActive a "mild hybrid" application and says it cuts CO2 emissions by 8 to 15 percent.
PSA will also offer more gas-powered vehicles. It currently offers the Citroen Jumper/ Peugeot Boxer light commercial vehicles in CNG (compressed natural gas) and LPG (liquefied petroleum gas) variants, with technology from light commercial vehicle partner Fiat Auto.
CNG and LPG variants are about to be added to the Citroen Berlingo and Peugeot Partner, this time using PSA's proprietary technology.
The engines use direct-injection technology that will be supplied by German supplier Siemens.
PSA has been largely unsuccessful in getting other automakers to adopt its particulate filter technology, although it has offered it. Ford will be the first non-PSA automaker to offer it.
