There is more information on the
Audi TDI® clean diesel model line in
the all-new 2014 Audi TDI® clean
diesel brochure. See your dealer or
go to audiusa.com for details.
Making diesel cleaner
A new refinement process binding sulfur
molecules to hydrogen has reduced sulfur in
diesel fuel by more than 97% in years past.
1 Obey all speed and traffic laws. 2 24 city/31 highway/27 combined mpg (2014 Q5 TDI® clean diesel with eight-speed Tiptronic® automatic transmission and Audi quattro® all-wheel drive). EPA estimates. Your mileage will vary.
Increased fuel eciency
Another way diesel creates fewer
emissions is that it gets better
mileage, up to 20% more mpg
than comparable gasoline en-
gines, in fact.

Variable vane turbocharger
Adding turbo power to clean diesel en-
gines, our adjustable vane turbocharger
produces impressive torque punch and
mid-range passing speeds.

We thought you should know: Diesel sports a greater power density than traditional gasoline, which
means that a gallon of diesel fuel has about 15% more energy than a comparable amount of gas, and
combusts more eciently in the engine. The Audi TDI® clean diesel engine has achieved ultra-low emis-
sions vehicle (Bin-5/ULEV) status in all 50 states while producing approximately 20% fewer CO

emissions
than the traditional gasoline-fueled engine. And the brainy attributes don’t hide the brawn—in fact, Audi
has dominated the 24 Hours of Le Mans over the years with Audi TDI® prototype race cars. With these
facts in mind, maybe you are thinking that an Audi TDI® might be your choice—which goes to show that
clean diesel really is fuel for thought.
Fuel for thought.
Combustion
Combining a high compression ratio
with direct injection makes combustion
more ecient, and produces emissions
cleaner than those of engines with a
lower compression ratio.
After-exhaust treatment
With innovative diesel particulate
filters and the nontoxic AdBlue®
reducing agent, we eliminate up to
95% of diesel NO
X
emissions.
Diesel packs more energy
On average, one gallon of diesel contains
about 147,000 BTUs, versus 125,000
for gasoline.
Piezo direct injection
Precise injections help lower the combus-
tion noise normally associated with diesel
engines, while optimizing the distribution
of fuel in the combustion chamber, helping
to further reduce exhaust emissions.
