There's an old line that "racing
improves the breed" that goes back to the origins of the industry. Indeed, many
innovations developed on the race track have made their way back to road going
cars including rear view mirrors and fuel injection. Someday, there might even
be an innovation in NASCAR, but that's another story. Over the last two decades,
Audi has been particularly active in motorsports, first in rallying- where its
Quattro all wheel drive was spawned - and later on race tracks - where it
debuted gasoline direct injection on the R8. Most recently, the R10 and the R15
have taken diesel technology to new heights with three consecutive wins at Le
Mans.
Audi's now using that racing success to boost its first U.S. clean
diesel vehicle, the Q7 TDI, which is finally going on sale about now. Last fall,
in the cross country Mileage Marathon, the 50-state legal Q7s averaged about 29
mpg, far more than any of the big hybrid SUVs can manage. Yes, diesel contains
more carbon than gasoline but the 30 percent improvement in efficiency far
outweighs the extra carbon content and still yields about a 25 percent cut in
CO
2 emissions. While even clean diesels also produce more NOx than
current gasoline engines, they are a huge improvement over they were and the
particulate filters like those used on the race cars eliminate the soot.

clean diesel technology to be sold in U.S. for first time this spring

HERNDON, Va., Mar 31, 2009 - From politicians to
marketers, from oil companies to environmentalists. No matter who you speak to
these days - it seems like everyone has an idea to reduce U.S. dependence on
foreign oil.
Wind turbines,
energy-saving light bulbs, hybrid cars...the list goes on. The truth is - they
all help in one way or another. But one solution is not just available in the
here and now, it was formed and perfected on the race track. Imagine, forging
the path to energy independence while driving 200 mph.
It sounds far-fetched. But it's true. The federal
government estimates that converting one-third of the cars on the road to clean
diesel - the fuel behind motorsports' most prolific race car - would allow the
U.S. to send back every barrel of oil from a foreign supplier the size of Saudi
Arabia.
Look at the list of
winning vehicles at the world's most well-known endurance race - the 24 Hours of
Le Mans. You will see one car listed as the winner for the past three years
running. That car is the Audi R10 TDI. The vehicle's dominance in Le Mans is
common knowledge in the world of motorsports. It is a tradition that lives on in
the Audi R15 TDI. Yet the race, and its significance, are lesser known here in
the United States. However, Le Mans influence will soon be felt.
This year, Audi will literally take its winning
racing formula and apply it to vehicles sold at dealers throughout the country
starting this spring. For the first time, U.S. drivers will reap the benefits of
the Audi racing team's not-so-secret weapon - TDI clean diesel.
In motorsports, a few seconds can separate winners
from losers. Every race team is looking for ways to limit pit stops. Diesel
engines make more efficient use of the energy released by their fuel than do
gasoline engines. This fundamental principle of physics has been refined through
many solutions that Audi has played a major role in developing - including the
four-valve technology that ensures optimum filling of cylinders in every
situation. The TDI engine compresses air to super-hot temperatures, so when the
fuel is injected more of it instantaneously combusts making the whole engine far
more efficient with every droplet.
Watching the drama unfold in the Le Mans documentary
"Truth in 24" (www.truthin24.com), you can see the Audi TDI clean diesel
engine's distinct advantage. The R10 TDI technology can drive further with fewer
pit stops - even compared to other diesel engines.
The results can't be ignored. The Audi R10 TDI has
never been beaten in the coveted 24 Hours endurance race of Le Mans. Upgraded to
the Audi R15 TDI, the clean diesel results have been the same. This month, the
R15 debuted at the 12 Hours of Sebring in Florida achieving the fastest Sebring
race ever, beating the previous distance record by 13 laps. Not only did the R15
run circles around the competition, the prototype racers won the Michelin Green
X Challenge award for achieving greater higher efficiency than their
competitors.
But what does this
mean for U.S. drivers? Why should you care about a European endurance race?
There answer is simple: The innovations on display at Le Mans will mean fewer
stops at the fueling stations and more value for your dollars when you fill up
your tank.
The same clean
diesel technology, which allows Audi Le Mans drivers to go farther on a single
tank, will now be available in Audi TDI vehicles sold in the United States -
starting with the Audi Q7 TDI. The outstanding efficiency of Audi's TDI engines
benefits the driver of a Q7 TDI both when it comes to saving money and when it
comes to covering long distances: with its 26 gallon tank, the car can cover
more than 600 miles on a single fill up - saving the cost, time and annoyance of
extra stops at the filling station.
That's a big benefit
for America and American households. Consider the 15,000 miles on average that
an American family drives each year. Simple math suggests they're on the road
more than 280 miles a week. With the range made possible by clean diesel's fuel
efficiency, that average family will only need to stop at a filling station
twice a month - even if they are driving a sizeable SUV.
Each month throughout 2009, Audi is highlighting
specific symbols of progress by providing facts, photos, videos, and information
about Audi innovation. Learn more about TDI and the Audi R10 by watching TDI in

at the pump, progress in emissions, and progress on foreign oil.
