The i-StARS is the second generation of Valeo’s Stop-Start system.
It will be launched at the third quarter of 2010.
It allows the automatic engine cut off during a traffic light or traffic jam, it restarts automatically with a touch on the throttle pedal.
The average emissions reductions are 5g of CO² per kilometer and can go up to 15% in intense urban conditions.
Whenever the speed goes under 8km/h (5 mph) for an automatic gearbox and 20km/h (12,4mph) for a mechanical gearbox, the system cuts the engine, the restart is immediate (400msec).
Since the first version of the system, Valeo has had orders from 10 manufacturers and equips 50 models.
