Peugeot displayed a 308 hatchback with Stop and Start technology at the Paris Motor Show. With the new technology fuel consumption is only 4.1 litres/100 km.

While much of the attention at the Peugeot display in Paris was focused on the RC HYmotion4 and Prologue concepts, the company also had a special technological demonstrator version of the 308 hatchback with Stop and Start technology on display.

Power comes from the 1.6 liter HDi engine which produces 82 kW (about 112 bhp) but thanks to Stop and Start technology fuel consumption for the combined cycle is only 4.1 litres/100 km while C02 emissions are reduced to 109g/km.

The technology works by turning off the engine when the vehicle comes to a stop at traffic lights or in congestion, then restarts the engine automatically when the accelerator is pushed. The system is powered by a battery which is recharged during deceleration. Further fuel saving are aided by an electronically-controlled 6 speed manual gearbox. All together these systems work to dramatically increase fuel economy up to 15% in urban driving.

Don’t look for this special 308 at dealership anytime soon, as the company is currently studying the technology for production in 2011.
