Journalists from around the world will compete for the title of most fuel-efficient diesel driver, and TheCarConnection.com will be there next month to take part in the cross-country rally.
The brand with the four interlocking rings (symbolizing the merging of German firms Auto Union, DKW, Horch, and Wanderer) will be introducing Audi's as-yet-unseen (in the U.S.) 3.0 TDI V-6 in the Q7, Q5, and A4. Powering the A3 will be a version of the 2.0-liter TDI found in corporate parent VW's Jetta TDI Clean Diesel.
Audi boasts extreme cleanliness where emissions are concerned, with emissions compliance in all 50 states (Mercedes did it first) and with Euro 6 standards that won't go into effect until 2014 (impressive).
Following the endurance test, Audi will launch its U.S. TDI models for the '09 model year.
