Not all features listed here are included on every Citroën model; please refer to our model showrooms to discover the technology features on specific models.

HDi technology

1800x681_citroen-motorisations-technologie-hdiCitroën’s HDi (High-pressure Diesel Injection) engines use common rail technology, in which a single rail feeds the injectors at very high pressure.

This electronically controlled system optimises the fuel-air mix under all conditions of use, significantly reducing fuel consumption and CO2 emissions.

The high precision of the latest-generation common rail injection system also increases engine efficiency. HDi diesel engines offer a number of proven benefits, from increased reliability and a smoother drive, to plenty of torque at low revs, low noise levels and reduced fuel consumption and pollutant emissions.

e-HDi micro-hybrid

1800x681_citroen-motorisations-micro-hybride-e-hdiThis technology, which is available for HDi engines, features a second-generation Stop&Start system, with a reversible alternator and an e-booster that immediately restarts the engine in just 0.4 seconds.

Not only does the e-HDi micro-hybrid technology offer a remarkably pleasant drive, but it is environmentally-friendly too.
The micro-hybrid e-HDi technology converts the kinetic energy that is produced when decelerating into electricity in order to cut fuel consumption and CO2 emissions by as much as 15% in towns.

BlueHDi (SCR system)

1800x681_citroen-motorisations-bluehdiThe new Euro6-compliant BlueHDi 150 and 180 engines deliver reduced fuel consumption and emissions (from 110 g of CO2/km).

-The SCR (Selective Catalytic Reduction) system, which is exclusive to PSA, is located before the particulate filter and uses an additive to treat the exhaust fumes more quickly than the competition’s solutions.
-The NOx (nitrogen particles) are transformed into steam and nitrogen (an inert gas) in a chemical reaction with the AdBlue® additive.
The BlueHDi 150 engine is available in the new Citroën Grand C4 Picasso.
The BlueHDi 180 engine is available in the Citroën DS5.


1800x681_citroen-motorisations-puretechCitroën’s PureTech engines are fitted with the very latest technology for an energetic drive and reduced fuel consumption.

The VTi 68, VTi 72 and VTi 82 all belong to the new family of PureTech petrol engines.

Compared with the preceding generation, this family of engines cuts fuel consumption and CO2 emissions (from 87 g/km) by about 25%, while offering an even more dynamic performance!
