Getting the maximum performance from every drop of diesel while also reducing environmental pollution. Mercedes-Benz has taken on this challenge with its economical diesel engines and revolutionary BLUETEC diesel technology.
After BLUETEC was tried and tested in the bus and truck segments, it was used for the first time in passenger cars from 2006. The V6-cylinder E 320 BLUETEC had its world premiere when it was introduced in the US in autumn 2006. Its emissions fall below the US standard BIN 8 and, with a fuel consumption of 6.7 litres per 100 kilometres, corresponding to CO2 emission of 179 g/km, is clearly the most economical vehicle of its class in the US. This technology will be available in Europe in the E 300 BLUETEC from December 2007. It already currently meets the EURO-5 standard for new vehicles, which will take effect from 2009, and is the cleanest and most economical EURO-5 diesel passenger car worldwide in the business class.
Two versions of BLUETEC have been developed: in the E 320 BLUETEC and E 300 BLUETEC, an oxidation catalytic converter, an additive-free diesel particulate filter, NOxstorage catalytic converter with onboard ammonia generation and an SCR catalytic converter ("Selective Catalytic Reduction") are all combined, enabling exemplary values for all the exhaust gas components. In the second BLUETEC version, a special additive, AdBlue, converts up to 80 percent of the nitrogen oxides into harmless nitrogen and water. A great step forward for a clean environment.
