While the power rating seem to stray behind the leading four-cylinder turbo, V6 and V8 engines, the car company revealed that the new diesel engine is, by far, the leading Citroen-produced engine in terms of power output. Apart from getting an additional 32HP, it is also more fuel efficient by 15%. This ranking can go up to 17% depending on how the diesel engine is applied.

The new set up will come with the existing C5 and C6 models which both received an average of 31mpg in the US combined cycle—that’s a 13% and 17% improvement for C5 and C6 respectively—as compared to its predecessor the 2.7HDi V6 208hp unit. The new engine comes with the Diesel Particulate Filter System (DPFS) that effectively traps particulate matter. Emissions for both models are down to 195g/km.

This new engine technology is combined with Citroen’s third generation common rail direct injection system. The new system ensures that the drivers will only get a pleasurable driving experience with the high-powered engine’s smooth performance.

Citroen’s new diesel engine will be available in the market later in the summer—a debut that will ready the consumers for the strict application of the 2011 Euro V emissions.
