Citroen-DS5-6512012 Citroen DS5 Hybrid4 is now more efficient than ever before. The engineers from the popular French brand have made him environmentally considerate and thus appealing even more to customers.

As a matter of fact, all three Hybrid4 200 Airdream EGS6 models in the DS5 range have received technical updates so that they can now deliver CO2 emissions from just 91g/km. In addition, this decrease in CO2 emission goes hand-in-hand with improved fuel economy.

To go further into details, the enhanced fuel efficiency is due to new management software. The latter was developed for the full-hybrid diesel powertrain with a number of technical improvements so that now this Citroen model has optimized efficiency.

Here some important enhancements include improved energy recovery when decelerating and braking, and a new battery management system. This makes the newly re-homologated DS5 Hybrid4 drivetrain reducing the official CO2 emissions for the DSign model from 99g/km to 91g/km (BIK tax band 10%).

Moreover, DStyle and DSport versions see their emissions reduce from 107g/km to 102g/km, with a BIK band change from 12% to 11%. Another feature, which reduces the emissions, is the 17-inch ‘Houston' alloy wheels.

They are available as a no-cost option on Hybrid4 DStyle and DSport versions. The wheels have smaller diameter thus reducing the cars' CO2 emissions from 102g/km to 91g/km - the same as the entry-level DSign (giving a further BIK reduction from 11% to 10%).
