BlueTEC is Daimler AG's marketing name for engines equipped with advanced NOx reducing technology for vehicle emissions control in diesel-powered vehicles. The technology in BlueTec vehicles includes a selective catalytic reduction (SCR) system that uses diesel exhaust fluid, and a system of NOx Adsorbers the automaker calls ''DeNOx'', which uses an oxidizing catalytic converter and diesel particulate filter combined with other NOx reducing systems. The BlueTEC was on the Ward's 10 Best Engines list for 2007 and 2008. ==Uses== Daimler introduced BlueTEC in the Mercedes E-Class (using the DeNOx system) and GL-Class (using SCR) at the 2006 North American International Auto Show. At that time, these BlueTEC vehicles were 45- and 50-state legal, respectively, in the United States (a 45-state vehicle does not meet the more stringent California emission standards that have also been adopted by four other states). Daimler AG has entered into an agreement with Volkswagen and Audi to share BlueTEC technology with them in order to increase the Diesel passenger-vehicle market 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 the Tiguan use NOx adsorbers, while the Touareg uses a Selective Catalytic Reduction catalytic converter. In August 2007 VW Group announced that cooperation on BlueTEC with Daimler AG would end. The reasoning for this change is due to the recognition of the VW TDI branding. VW did not want to use a competitor's branding for a product they would introduce into the market. 〔http://money.cnn.com/news/newsfeeds/articles/newstex/AFX-0013-18676102.htm 〕 VW developed their own system, but it failed and they re-programmed the engine control to show false values during pollution tests.〔(【引用サイトリンク】title=Ingenieure gestehen Installation von Manipulations-Software )〕〔http://www.nytimes.com/2015/10/05/business/engine-shortfall-pushed-volkswagen-to-evade-emissions-testing.html〕 By 2010 a BlueTEC version of the Mercedes Sprinter was released.
