Audi Completes 4800 Mile Rally and the Winner is . . . Clean Diesel

Audi Completes 4800 Mile Rally

  • Audi’s TDI fleet completes coast-to-coast Mileage Marathon
  • Audi’s Q7 3.0 TDI averages 28 mpg across country and 30 mpg on final leg
  • Audi A3 2.0 TDI averages 45 mpg over entire Marathon


With the streets and highways of America as its driving course, Audi proved clean diesel passes the real-world test. Completing the cross country Mileage Marathon, Audi’s TDI fleet not only redefined diesel as a ultra-low emission alternative to gas-powered vehicles, but also posted noteworthy fuel efficiency numbers. Covering over 4800 miles from New York to Santa Monica, the Audi A3 TDI averaged 45 mpg, the Audi A4 vehicles averaged 36 mpg over the drive, and the Audi Q5 TDI vehicles averaged 32 mpg. The Audi Q7 TDI vehicles, clean diesel SUVs which will be the first TDI vehicles available in the Unites States early next year, averaged an excellent 28 mpg over the entire drive.




Along the route, teams of drivers and journalists competed for the best efficiency totals based on miles-per-gallon and average speed. During the final leg, the lead over all vehicles in fuel economy with 40 mpg was the Audi A3 2.0 TDI.
