HDi engines are top of the range. Polluting less and using less fuel than conventional diesel engines, they cut CO2 emissions and fuel consumption by 20%. They also use an electronically controlled system to optimise the air/fuel mix and reduce emissions.

The Diesel Particulate Filter System (DPFS) on the HDi engines helps protect the environment by trapping and burning particles produced by the engine. This means that the particulate emissions of the Citroën C6 drop to barely measurable levels that are even beyond future EU environmental standards.

The Citroën C6 is built in France at our Rennes site, where we’ve invested heavily in the environment and in sustainable development. Our industrial facilities use the latest technologies and the site has ISO 14001 certification.
