Technical data

42 TDI®
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 gram.
Pre-injection results in a “gentle”
combustion process and consequently
excellent combustion acoustics and
agreeable engine running
characteristics.
One in every two Audi cars sold today is a diesel.
What sounds perfectly normal now was cause for
huge excitement 20 years ago, when Audi
revolutionised the market with the first 2.5 litre
TDI engine. Since then, developments such as
common rail technology have made TDI even
more efficient. Piezo injectors ensure the fuel is
finely and precisely distributed. Consequently,
since the first TDI, the engines have become
more economical, whilst specific output has
increased. So it was only logical that a diesel car
should then enter the world of motorsport. And
successfully too: in 2006, Audi was the first car
maker to win the 24 Hours of Le Mans with a
diesel-powered race car, the Audi R10 TDI – a
victory which it has repeated several times over.
Powerful TDI engines in three power outputs
are available for the Audi A7 Sportback, which of
course feature intelligent common rail diesel
technology. With a hefty 580 Nm of torque,
the 180 kW 3.0 TDI quattro accelerates your
A7 Sportback from 0 to 100 km/h in 6.3 seconds,
the 230 kW 3.0 TDI quattro in just 5.3 seconds.
And the 150 kW 3.0 TDI, with an extremely low
consumption of 5.1 l and CO₂ emissions of just
135 g, proves that efficiency does not prevent
driving pleasure.
The 3.0 TDI with 180 kW is also available as a
clean diesel version with quattro and S tronic
dual-clutch transmission. This engine uses
technology which specifically reduces nitrogen
oxides. In this version it complies with the EU6
emission standard.
The fuel consumption and CO₂ emission figures can be found from page 104 onwards.
