Citroen's eco plans

Citroen has revealed plans to introduce stop-start technology and more fuel-efficient gearboxes across its range, as it prepares to launch an environmentally friendly eco-brand.

Stop-start is expected to be rolled out over the next couple of years, and will be fitted to larger cars, such as the C5 and C6, as well as smaller models.

Citroen has also confirmed plans to fit its EGS semi-automatic gearshift to the C3 Picasso from 2011. The system features a paddle gearshift, but works like a manual. It is already available in Citroens, including the Grand C4 Picasso.

C3 Picassos powered by larger engines will also be sold with six-speed manual gearboxes to improve efficiency, again from 2011.

• Citroen officials have also confirmed the Xsara Picasso is likely to be taken off sale by the end of the year.
