The Audi S6 in figures: V8. 4.0 TFSI
®
. Significantly less CO₂ emissions in
comparison with the prior model. 309 kW generate a powerful torque
of 550 Nm and power the Audi S6 Saloon from 0 to 100 km/h in
4.6 seconds. Innovative cylinder management, the start-stop system and a
new thermal management system turn the car into an efficient top athlete.
This more intelligent power lends the Audi S6 its particularly progressive
and splendid sportiness and its fascinating dynamics.
Efficiency: the art of reducing
without losing out.
In just a few seconds you will understand why.
Audi cylinder on demand in the TFSI
®
engine
If the V8 4.0 TFSI
®
engine of the Audi S6 does not require the full power of the 8 cylinders in the
partial-load range, the inlet - and outlet valves of 4 cylinders – 2 each per cylinder bank – are closed
by Audi cylinder on demand and their ignition and fuel injection are switched off. This means that
neither is air taken in, fuel injected nor is exhaust gas emitted. The deactivation depends on several
factors: the engine speed must be between 960 and 3,500 rpm, the vehicle must be travelling at a
minimum speed of 25 km/h and on the 7-speed S tronic you must be driving in third gear or higher.
TFSI
®
technology, among others, is employed in the
Audi S6 models. And the remarkable thing about it is:
It combines the advantages of FSI with a supercharger,
which ensures even better power delivery.
The Audi S6 has a V8 4.0 TFSI
®
engine that features the
new innovative Audi cylinder on demand. It ensures
that during partial load operation, only four of 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.
Thanks to its very spontaneous responsiveness and
exceptional power delivery across the entire speed
range, the eight-cylinder engine promotes a sporty
superior driving style. Its 309 kW accelerate the
S6 Saloon at a torque of 550 Nm from 0 to 100 km/h
in 4.6 seconds. The engine is electronically limited
at 250 km/h.
TFSI
®
engines in the S6 models comply with the EU5
emission standard.
