<strong>Audi</strong> cylinder on demand in the TFSI<br />
engine. If the V8 4.0 TFSI engine of<br />
the <strong>Audi</strong> <strong>S7</strong> <strong>Sportback</strong> does not need<br />
the full power of 8 cylinders in the<br />
partial-load operational range, <strong>Audi</strong><br />
cylinder on demand closes the intake<br />
and outlet valves of 4 cylinders – 2 each<br />
per cylinder bank – and their ignition<br />
and fuel injection are switched off. This<br />
means that neither is air taken in or<br />
fuel injected nor is exhaust gas emitted.<br />
The system will only kick in under certain<br />
conditions: when revs are between 960<br />
and 3,500 rpm, the speed is at least<br />
25 km/h and you are travelling in at<br />
least third gear of the 7-gear S tronic.<br />
4.0 TFSI engine (<strong>S7</strong> engine)<br />
In just a few seconds you will understand why.<br />
Among other things, TFSI technology is employed<br />
in the <strong>Audi</strong> <strong>A7</strong> <strong>Sportback</strong>. Its unique feature is<br />
that it combines the advantages of FSI with a<br />
supercharging system, which ensures even better<br />
power delivery.<br />
The 3.0 TFSI quattro generates a hefty 228 kW of<br />
power. An innovative mechanical supercharging<br />
system with intercooler is employed here and<br />
turns the 6-cylinder engine into a compact<br />
powerhouse with moderate fuel consumption.<br />
It is not just the peak torque of 440 Nm that is<br />
impressive, there is also the torque curve: with<br />
at least 90 % of the maximum torque being<br />
available across an engine speed range of 2,900<br />
to 4,500 rpm. Thanks to its very spontaneous<br />
responsiveness and exceptional power delivery<br />
across the entire engine speed range, the<br />
6-cylinder engine promotes a particularly<br />
dynamic driving style. The <strong>Audi</strong> <strong>A7</strong> <strong>Sportback</strong><br />
accelerates to 100 km/h in 5.6 seconds – and still<br />
has plenty of power reserves left after that.<br />
The <strong>Audi</strong> <strong>S7</strong> <strong>Sportback</strong> has a V8 4.0 TFSI engine<br />
that features the new innovative <strong>Audi</strong> cylinder on<br />
demand. This ensures that during partial load<br />
operation, only four of the eight cylinders are<br />
used – without you noticing the difference. The<br />
engine runs just as smoothly and powerfully,<br />
but using less fuel and emitting less CO₂. Thanks<br />
The fuel consumption and CO₂ emission figures can be found from page 104 onwards.<br />
to its very spontaneous responsiveness and<br />
exceptional power delivery across the entire<br />
engine speed range, the 8-cylinder engine<br />
promotes a sporty superior driving style. Its<br />
309 kW accelerate the <strong>S7</strong> <strong>Sportback</strong> at a torque<br />
of 550 Nm from 0 to 100 km/h in 4.7 seconds.<br />
The top speed is electronically regulated at<br />
250 km/h.<br />
The 2.8 FSI with 150 kW and <strong>Audi</strong> valvelift<br />
system (AVS) completes the engine options for<br />
the <strong>Audi</strong> <strong>A7</strong> <strong>Sportback</strong>. The variable valve control<br />
system of the AVS helps to reduce fuel<br />
consumption.<br />
In conjunction with the 7-speed S tronic® dualclutch<br />
transmission and quattro permanent<br />
all-wheel drive, the 2.8 FSI accelerates from<br />
0 to 100 km/h in just 8.3 seconds.<br />
All FSI and TFSI engines in the <strong>Audi</strong> <strong>A7</strong> <strong>Sportback</strong><br />
and <strong>S7</strong> <strong>Sportback</strong> comply with the EU5 emission<br />
standard.
