Audi is launching its TDI initiative on the North American market as early as next year. The auto maker will be putting the cleanest diesel engine in the world into production in the U.S. Virtually in parallel to its launch in Europe, the 3.0 TDI with ultra-low emission system will initially be available for the Audi Q7, and later for the new Audi A4. Audi has been expanding steadily in the U.S. for many years and sees the market as holding high potential for its cutting-edge TDI engines. The low-sulphur fuel required for the engines’ operation was introduced throughout the country a year ago, paving the way for the initiative to begin. According to calculations by the Environmental Protection Agency (EPA), the United States could save 1.4 million barrels of crude oil every day if just one third of all passenger cars and light-duty commercial vehicles were equipped with up-to-date diesel engines. The new Audi 3.0 TDI develops an output of 240 hp and 406 lb.-ft. of torque while new technologies optimize the combustion process in the V6: the common-rail injection system builds up 29,400 psi of pressure, while sensors monitor the combustion chambers.
