BlueTEC is the marketing name of Daimler AG for engines equipped with advanced NOx reduction technology for the control of vehicle emissions in diesel vehicles. The technology of the BlueTec vehicles includes a selective catalytic reduction (SCR) system that uses diesel exhaust fluid and a system of NOx adsorbents called DeNOx, which uses an oxidizing catalytic converter and a diesel particulate filter combined with other reducing systems NOx. BlueTEC was on Ward's list of 10 best engines for 2007 and 2008.
In February 2016, Mercedes-Benz was sued by private plaintiffs claiming that BlueTec violates the standards in a manner similar to the Volkswagen emissions scandal. On December 6, 2016, Federal District Judge José L. Linares rejected the lawsuit, finding that the plaintiffs had not declared themselves in suspense. The company introduced the BlueTEC Mercedes-Class E (using the DeNOx system ) And the GL Class (using SCR) 2006 North American International Motor Show. At that time, these BlueTEC vehicles were 45 and 50 legal states, respectively, in the United States (a vehicle from 45 states does not meet the most stringent California emission standards that have also been adopted by four other states).
Daimler AG has signed an agreement with Volkswagen and Audi to share BlueTEC technology with them in order to increase the market for Diesel passenger vehicles in the United States. VW introduced the Jetta Clean TDI, the Tiguan concept and the Touareg BlueTDI as part of the BlueTec licensing program. The Jetta and Tiguan use NOx adsorbents, while the Touareg uses a catalytic selective reduction catalyst. In August 2007 the VW Group announced that the cooperation in BlueTEC with Daimler AG would end. The reason for this change is due to the recognition of the VW TDI brand. VW did not want to use a competitor's brand for a product it would introduce to the market. VW developed its own system, but failed and re-programmed the engine control to display false values during pollution testing.
In 2010, a BlueTEC version of the Mercedes Sprinter was launched. BlueTEC systems allowed the removal of much of the EGR in that vehicle's engine, resulting in 188 horsepower (140 kW) compared to the 154-horsepower non-BlueTec (115 kW) engine. Daimler Trucks uses BlueTEC on all its Freightliner and Western Star trucks for use on the road, as these vehicles are only available with diesel engines.
