Valeo's starter-alternator to equip future PSA Peugeot Citroën vehicles from 2004

Paris, France, September 10 -- At the IAA, PSA Peugeot Citroen confirmed that Valeo's belt-driven starter-alternator would equip a future undisclosed vehicle model due in production in 2004. The new vehicle model is expected to be the first in the world with a 14 Volt belt-driven starter-alternator.

Valeo's belt-driven starter-alternator combines the functions of the starter and alternator into one easy-to-install unit that, through electronic control, not only efficiently generates electrical energy but is also capable of performing the function of a conventional starter motor. The system enables the "start-stop" mode - a fuel saving feature that automatically cuts off the engine when the vehicle is at a standstill and instantaneously and silently restarts it when the driver engages a gear or releases the brake.

Using existing alternator engine mountings, the system is a flexible "bolt-on" solution that does not intrude on the powertrain design, unlike integrated starter-alternators which are located between the engine and the transmission and subsequently require extensive re-design of these systems.

Consumers will benefit from up to ten percent fuel savings, reduced noise levels while cranking, no noise and zero emissions at standstill as well as longer "tank life". The environment is further protected because of zero emissions while at standstill. In congested urban traffic conditions this period can be greater than 30 percent of the driving time. Car makers will appreciate the compact and flexible design and the benefits of the system which complies with European as well as international environmental regulations.

Valeo is an independent industrial Group fully focused on the design, production and sale of components, integrated systems and modules for cars and trucks. Valeo ranks among the world's top automotive suppliers. The Group has 130 plants, 54 R&D centers, 9 distribution centers and employs 69,000 people in 25 countries worldwide.
