Audi cylinder on demand in the TFSI
engine. If the V8 4.0 TFSI engine of
the Audi S7 Sportback does not need
the full power of 8 cylinders in the
partial-load operational range, Audi
cylinder on demand closes the intake
and outlet valves of 4 cylinders – 2 each
per cylinder bank – and their ignition
and fuel injection are switched off. This
means that neither is air taken in or
fuel injected nor is exhaust gas emitted.
The system will only kick in under certain
conditions: when revs are between 960
and 3,500 rpm, the speed is at least
25 km/h and you are travelling in at
least third gear of the 7-gear S tronic.
4.0 TFSI engine (S7 engine)
In just a few seconds you will understand why.
Among other things, TFSI technology is employed
in the Audi A7 Sportback. Its unique feature is
that it combines the advantages of FSI with a
supercharging system, which ensures even better
power delivery.
The 3.0 TFSI quattro generates a hefty 228 kW of
power. An innovative mechanical supercharging
system with intercooler is employed here and
turns the 6-cylinder engine into a compact
powerhouse with moderate fuel consumption.
It is not just the peak torque of 440 Nm that is
impressive, there is also the torque curve: with
at least 90 % of the maximum torque being
available across an engine speed range of 2,900
to 4,500 rpm. Thanks to its very spontaneous
responsiveness and exceptional power delivery
across the entire engine speed range, the
6-cylinder engine promotes a particularly
dynamic driving style. The Audi A7 Sportback
accelerates to 100 km/h in 5.6 seconds – and still
has plenty of power reserves left after that.
The Audi S7 Sportback has a V8 4.0 TFSI engine
that features the new 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 runs just as smoothly and powerfully,
but using less fuel and emitting less CO₂. Thanks
The fuel consumption and CO₂ emission figures can be found from page 104 onwards.
to its very spontaneous responsiveness and
exceptional power delivery across the entire
engine speed range, the 8-cylinder engine
promotes a sporty superior driving style. Its
309 kW accelerate the S7 Sportback at a torque
of 550 Nm from 0 to 100 km/h in 4.7 seconds.
The top speed is electronically regulated at
250 km/h.
The 2.8 FSI with 150 kW and Audi valvelift
system (AVS) completes the engine options for
the Audi A7 Sportback. The variable valve control
system of the AVS helps to reduce fuel
consumption.
In conjunction with the 7-speed S tronic® dualclutch
transmission and quattro permanent
all-wheel drive, the 2.8 FSI accelerates from
0 to 100 km/h in just 8.3 seconds.
All FSI and TFSI engines in the Audi A7 Sportback
and S7 Sportback comply with the EU5 emission
standard.
