V8 TFSI engine
The Audi RS 6 Avant has a V8 4.0 TFSI engine
that features the innovative Audi cylinder on
demand. This ensures that during partial load
operation, only four of the eight cylinders are
used – without you noticing the difference. The
engine always runs smoothly and powerfully,
but it uses less fuel and emits less CO₂.
We describe its mode of operation as “intelligent
performance”. Audi cylinder on demand selectively
closes certain cylinders, two per cylinder bank. As a
result, the engine runs impressively smoothly even
during partial load operation.
The deactivation depends on several factors:
the revs are between 960 and 3,500, the engine
temperature must be at least 30 °C and you
must be in at least third gear. If you then do
not need the full power of eight cylinders, the
Audi valvelift system closes the intake and
outlet valves and switches off the injection and
ignition of the corresponding cylinders. This
means that neither is air taken in and fuel
injected, nor is exhaust gas emitted. In other
words: the consumption and emission values
are noticeably improved.
In addition, the V8 4.0 TFSI engine features
a start-stop system and recuperation, and it
goes without saying that it complies with the
EU5 emission standard.
Thanks to its very spontaneous responsiveness
and exceptional power delivery across the entire
engine speed range, the 8-cylinder engine
promotes an impressive driving style. Its 412 kW
accelerate the RS 6 Avant at a torque of 700 Nm
from 0 to 100km/h in 3.9 seconds. The engine
is electronically regulated at 250km/h, but by
request also at 280 or 305km/h.
The fuel consumption and CO₂ emission figures as well as the efficiency class can be found on page 56.
