The fuel consumption and CO₂ emission figures can be found on page 121.

One in every two Audi cars sold today is a diesel.

What we take for granted now was quite a

sensation a mere 20 years ago when Audi

revolutionised the market with the first 2.5 litre

TDI engine. Developments in technology such as

common rail technology have since made TDI

more and more efficient. Piezo injectors provide

for a refined and precise fuel distribution.

Consequently, since the first TDI, the engines

have become more economical, whilst specific

output has increased. That’s why it was only

logical for a diesel to enter the world of

motorsport. And successfully too: in 2006, Audi

was the first car maker to win the Le Mans 24

Hours with a diesel-powered race car, the Audi

R10 TDI – and then went on to repeat this victory

several times over, most recently in 2011.

Powerful TDI versions in 4 power outputs are

available for the Audi A6, which of course

operate with intelligent common rail diesel

technology. The most efficient engine in the

Audi A6 is the 2.0 TDI with 130 kW and a torque

of 380 Nm. With this engine variant the

A6 Saloon consumes just 4.9 l while producing

CO₂ emissions of 129 g. The 6 cylinder engines

likewise demonstrate the fact that driving

pleasure does not have to come at the expense

of efficiency.

The 3.0 TDI with 150 kW consumes just 5.3 l

while producing CO2 emissions of 139 g. With a

hefty torque of 580 Nm, the 3.0 TDI quattro

with 180 kW accelerates your A6 Saloon from

0 to 100 km/h in 6.1 seconds and the A6 Avant

in 6.3 seconds.

As a clean diesel version, it uses technology

which specifically reduces nitrogen oxides. In

this version it complies with the EU6 exhaust

emission standard. The 3.0 TDI quattro, which is

designed as a bi-turbo, has a peak output of

230 kW.

The piezo injectors open and close

in fractions of a millisecond and

inject fuel several times into the

combustion chamber at pressures

of up to 1,800 bar. In some cases,

an injection process can involve the

injection of the tiniest of amounts

weighing less than a thousandth of

a gramme.

Pre-injection results in a “gentle”

combustion process and

consequently excellent combustion

acoustics and agreeable engine

running characteristics.
