EEV, which means Enhanced Environmentally Friendly Vehicle, is a classification used for engines which comply with an even more stringent exhaust emission standard than Euro 5. The EEV standard reduces particulate emissions by roughly a further one third compared to the already stringent Euro 5 limits. In extending its truck range, Mercedes-Benz will be gradually introducing EEV versions in certain output classes of the Mercedes-Benz Actros, Axor and Atego up to July 2010. BlueTec EEV is already part of the extended specification for the Mercedes-Benz Econic from January 2010. Incentives are offered for this technology in some European countries. The engines in the OM 920 and OM 501 series have been developed even further for this purpose. Mercedes-Benz commercial vehicles equipped with this feature can be recognized by the additional “BlueTec EEV” model plate.
