Peugeot has presented its e-HDi technology, a new generation diesel stop & start system. The new e-HDi Stop & start technology turns off a car’s engine when stationary, which in turn delivers improvements in fuel efficiency and CO2 emissions of up to 15%. To be deployed across the Peugeot range from late 2010, the PSA Group aims to sell one million vehicles equipped with e-HDi by 2013.

The e-HDi system’s unrivalled performance reflects the combination of several technologies:
- An HDi engine, one of the industries most efficient powerplants
- A stop & start system with a second-generation reversible starter-alternator
- An e-booster system, for instantaneous engine restart
- An electronic alternator management system, for regenerative braking
- A gearbox with optimised gear ratios

In addition, all e-HDi-powered models will be fitted with low rolling resistance tyres.

e-HDi will enable the PSA Group to widen its lead in low-carbon vehicles. In 2009, PSA Peugeot Citroën sold nearly one million cars emitting less than 130g of CO2 per km, including more than 757,000 with emissions below 120g. The Group’s objective is to sell one million cars emitting less than 120g of CO2 per km in 2012. Under this plan and in addition to e-HDi technology, Peugeot will also launch the iOn all-electric car in late 2010, the Peugeot 3008 diesel hybrid in early 2011 and a new 1.0 litre petrol engine in 2012.

Development of the e-HDi system took 36 months, with more than 30 patents filed. A total of 500 engineers and technicians worked on the project. The project cost was €300 million.
