Peugeot Citroen's HDi Diesel Engine Production Tops the 10 Million Mark

PSA Peugeot Citroen has now produced more than 10 million vehicles equipped with the HDi engine, a key factor in reducing CO2 emissions.

Coming less than a decade after the Group introduced HDi technology in 1998, this success validates the commitment to high-volume production of modern diesel engines that offer superior environmental performance, driveability and fuel efficiency.

The HDi family of engines has enabled PSA Peugeot Citroen to maintain and expand its leadership in diesel technology and to outpace the fast growth in diesel sales in Europe over the past ten years.

It has also helped make the Group the European leader in CO2 emissions control.

An extensive, aligned offering

Deployment of common-rail technology across the Peugeot and Citroen model base has enabled the development of a diverse array of high-tech diesels, ranging from the 55hp, 1.4-litre 4-cylinder engine to the 205hp, 2.7-litre V6. The line-up comprises eight passenger car versions, steadily gaining in power in 14 to 34hp increments.

The HDi’s “Magic Square”

The success of the HDi engine stems from its alignment with both customer demand and the growing environmental consciousness of modern society. HDi-powered cars deliver properties symbolised by a “magic square” of fuel efficiency, driveability, quiet ride and clean running.

Leveraging their recognised expertise in diesel technology to develop the HDi, PSA Peugeot Citroen’s engineers have achieved unprecedented performance levels in terms of driveability, quiet ride and environmental footprint.

The HDi: an environmentally, socially responsible engine

The HDi reduces fuel consumption and CO2 emissions by 20% compared with the previous generation of pre-chamber diesels and by 30% compared with a petrol engine of the same size.

More efficient management of the combustion process provided by common rail technology has reduced carbon monoxide emissions by 40%, unburned hydrocarbons by 50% and engine particulates by 60%.

HDi technology has also enabled the Group’s engineers to develop the world’s first FAP particulate filter, which is gradually being introduced across the range of Peugeot and Citroen HDi models.

Significant additional reductions in fuel consumption and emissions are still possible thanks to the HDi’s potential for further improvements.

A major contributor to PSA Peugeot Citroen’s performance in reducing fuel consumption and CO2 emissions
The widespread deployment of HDi technology across the Peugeot and Citroen line-ups and the engine’s demonstrated success with customers have helped propel the Group to a position of leadership in energy-efficient vehicles and enabled it to achieve the best environmental performance in the market, both in France and elsewhere in Europe.

For the second year in a row, PSA Peugeot Citroen headed the list prepared by the French Agency for Environment and Energy Management (ADEME) that ranks carmakers in terms of CO2 emissions. With a 2006 corporate new car average of 140g/km, the Group had the lowest emissions of any automobile manufacturer in the French market.

HDi: a success that creates high-quality jobs

HDi engines are produced in the Group’s plants in Trémery in eastern France and Douvrin in northern France, as part of a co-operation agreement with Ford Motor Company. Thanks to the popularity of the engines and the expert skills of their production teams, both plants are world-class centres of excellence.
