The high-performance diesel technology TDI is one of Volkswagen’s core competencies. BlueTDI is a new concept that makes this technology even cleaner: exhaust aftertreatment reduces nitrogen oxides produced by up to 90 percent, making the Passat BlueTDI the most environmentally-friendly diesel in its class. Aboard the Passat BlueTDI, a SCR catalytic converter reduces nitrogen oxides to less than 80 mg/km.
