Supercharging. It’s the innovation that powered the legendary
Auto Union racers to win after win back in the 1930s, and it’s still
proving its worth today. It’s what enables the A6 allroad’s 3.0
TFSI engine to produce an exceptional 290PS of power, 420 Nm
of torque and better all-round performance than an equivalent
twin-turbo. The 3.0 TFSI also achieves lower fuel consumption
and more power than a conventional petrol engine. Fuel is
injected into each cylinder individually, at very high pressure,
which leads to greater efficiency. All while producing a lower
level of CO
2
than you might expect, meaning that the A6 allroad
3.0 TFSI already meets the proposed EU 5 emissions standards.
Diesel
There are two V6 diesel engines available in the A6 allroad: the
2.7 TDI and the 3.0 TDI. Their working principle is simple, yet
remarkably effective. A turbocharger supplies fresh air to the
engine, and immediately after compression an injector delivers
fuel into the combustion chambers at a very high pressure.
Advanced common-rail technology ensures that fuel is injected
into each cylinder individually, leading to a smoother, more
refined drive and impressive levels of torque. Of course, like its
FSI petrol counterpart, the TDI diesel engine also offers low fuel
consumption and CO
2
emissions. In fact, both TDI engines in the
A6 allroad range now comply with the stringent EU 5 emissions
limits scheduled for 2010.
