The reduction of CO2 emissions was one of the main objectives of this project. This resulted in a search for environmental efficiency at all levels. All factors influencing fuel consumption were optimised:

weight reduced by 25 kg on average per car;
launch of 16" tyres with Very Low Rolling Resistance;
use of a piloted oil pump on 1.6 litre HDi engines;
optimisation of operation of the alternator on some engines;
improvement of power steering control (electropump unit);
Cx of 0.28 for versions with a low fuel consumption - a record in the segment;
e-HDi micro-hybrid technology;
98 g/km of CO2 for the 1.6 litre e-HDi FAP 112 bhp BMP6 version - a record in the segment
