During the year, the Group sold nearly one million vehicles in Europe with emissions of less than 140 g CO2/km. Of these, more than 450,000 units emitted less than 120 g CO2/km, for a 38% share of the segment in Europe, and 200,000 emitted less than 110 g CO2/km.

This performance reflects an assertive commitment that has long led the Group to focus its research and development on lowering CO2 emissions.

One of the determining factors in meeting this goal has been the comprehensive revitalisation of the engine lineup. The broad deployment of modern HDi common-rail technologies across the model ranges has driven a 20% reduction in CO2 emissions compared with the previous generation of engines. More than nine million vehicles equipped with HDi common-rail engines have been sold to date.

In petrol engines, the joint development with BMW Group of the recently introduced family of small, advanced technology 1.6-litre engines with variable valve control or turbo direct injection has led to a further 10% reduction in CO2 emissions compared to the engines they replace. These engines are already being offered on the Peugeot 207.

PSA Peugeot Citroën is pursuing other research projects to reduce CO2 emissions, especially through the Hybrid HDi program. The Peugeot 307 Hybrid HDi demonstrator has set radical new performance standards with fuel consumption of 3.4 liters/100 km and CO2 emissions of 90 g/km.
