Citroën has announced new details about their advanced 240bhp 3.0-litre HDi V6 diesel engine, which will be introduced in the C5 and C6 this Summer.
Despite being more powerful than its predecessor, the 208bhp 2.7-litre HDi, the new engine boasts a 13-17% improvement in fuel efficiency and a 12-15% reduction in CO2 emissions. The Euro V compliant engine also features a piloted alternator which recovers energy during deceleration and braking, a diesel particulate filter system and Citroën's third generation of common-rail direct injection.
Thanks to all these improvements, the 3.0 HDi C5 and C6 get 38 mpg combined with CO2 emissions of 195g/km.
