The new micro-hybrid system will be introduced in 2010 on a range of petrol and diesel models.
Citroën was the first manufacturer to introduce Stop & Start with a combined alternator-starter on its C2 and C3 models, about four years ago.
Independent testing proved it could give a 27% fuel saving in urban traffic by turning off the engine as the vehicle comes to a halt and then instantly restarting it as soon as the brake pedal is released.
The new-generation Stop & Start system will retain the combined alternator-starter unit, which provides quiet, smooth and almost instantaneous restarts, and will produce even better fuel consumption and CO2 emissions. Improving the system’s environmental performance further, the new generation will also recover energy during braking and deceleration to recharge the vehicle’s battery without consuming fuel.
The show car delivers better economy than the standard model with almost 70mpg on the EU combined test cycle as well as low CO2 emissions of 110g/km thanks to the new Stop & Start technology and six-speed EGS (Electronic Gearbox System) automated manual transmission.
Diesel versions of the C3 Picasso line set for launch in 2009 will have a particulate filter system and will meet PSA’s green ‘Airdream’ criteria.
