Chicago. Subsequent daily stages – as long as 870 kilome-
ters (541 miles) each – took drivers southward along ex-
tended farmland. Memphis, Dallas and Denver were addi-
tional test-run destinations.
What is currently the world’s cleanest diesel made its de-
but at the Audi Mileage Marathon. Thus, the Audi Q7 3.0
TDI clean diesel faced its first real-world endurance test
several months prior to its scheduled 2009 launch in Eu-
rope and the United States. The exhaust emission-control
system reduces nitrogen oxides by as much as 90 percent
and meets what is currently the world’s most stringent
emission standard: California’s ULEV II BIN 5. And it al-
ready meets the emission limits of the Euro 6 standard,
not expected to come into force before 2014.
By the time the Audi fleet crossed the finish line on Octo-
ber 19, the drivers and their vehicles had completed a journey
through extremes: Within just hours, the tour stretched
from Death Valley – still 33 degrees centigrade even in Oc-
tober – to the snow-covered Sierra Nevada mountains.
It then passed through the natural beauty of Yosemite
National Park to Monterey and on southward along the
Pacific Coast. The Audi Mileage Marathon concluded in Los
Angeles’ Santa Monica with outstanding fuel-efficiency
figures. Calculated under the supervision of the independ-
ent International Motor Sports Association, these statis-
tics emphasize the efficiency of TDI technology. The best
Audi A4 3.0 TDI consumed an average of just 5.3 liters of
diesel per 100 kilometers. And the new performance SUV
Audi Q5 3.0 TDI required just 6.1 liters. The Audi Q7 3.0
TDI clean diesel achieved a best figure of 7.1 liters. The
prize for the best fuel efficiency went to the Audi A3 Sport-
back 2.0 TDI: a mere 4.7 liters! The fuel consumption of
TDI vehicles is thus as much as 40 percent lower than simi-
lar, gasoline-powered vehicles typical in the United States.*
TDI engines are just one element in the Audi brand’s
integrated strategy of further reducing the emission of
CO2and pollutants throughout the product range. Here
the company is combining the great potential of its
modern combustion engines with the synergies of new
technologies.
Along the many-faceted routes between the East Coast and
West Coast of the United States, Audi diesel technology
proved once again that excellent fuel efficiency and sporty
handling are not mutually exclusive and that innovative
developments such as TDI clean diesel lay the cornerstone
for the automotive future.
