TFSI® technology is used in the Audi A5 Coupé
and A5 Cabriolet. What’s special about that is: it
combines the advantages of FSI® with a
supercharging that ensures even better power
distribution. The two TFSI engines you have
available are all equipped with the economic
start-stop system and it goes without saying that
they comply with the EU5 emission standard.
The 1.8 TFSI has 125 kW of power and a
maximum torque of 320 Nm. And yet it is one of
the most fuel-efficient engines of its class: in the
ideal case, consumption is as low as 5.7 l per
100km in the A5 Coupé with manual trans-
mission. It accelerates from 0 to 100 km/h in
7.9 seconds. In the A5 Cabriolet you need
8.7 seconds to reach the 100 km/h marker. The
2.0TFSI has 155 kW of power and a maximum
torque of 350 Nm. This engine version is also
characterised by good consumption values and
low CO₂ emissions, and gets you from 0 to
100km/h in 6.5 seconds in the A5 Coupé with
quattro® drive and S tronic.
Many hours of development. Thousands of miles of testing.
And for what reason?
In just a few seconds
you will understand why.
The engine management system
calculates the injection quantity and
ignition timing according to how much
power the driver wants. In normal
operation, the injection pressure is
between 30 and 120 bar.

The S5 Coupé and the S5 Cabriolet are also fitted
with efficient TFSI® technology. These two
vehicles have a 3.0 TFSI V6 engine that generates
a powerful 245 kW. An innovative mechanically-
driven supercharger system with charge air
intercooler is employed here and turns the six-
cylinder engine into a compact powerhouse with
moderate fuel consumption. This is assisted by
the start-stop system that switches the engine
off automatically in different standstill
situations, and switches it on again when the
brake is released. The S5 Coupé and S5 Cabriolet
are exclusively available with the fast, 7-speed
double clutch S tronic and quattro® permanent
all-wheel drive
It is not just the peak torque of 440 Nm; also
impressive is the torque curve, with at least 90 %
of the maximum torque being available across a
speed range of 2,200 to 5,900 rpm. Thanks to its
spontaneous responsiveness and exceptional
power delivery across the entire speed range, the
six-cylinder engine promotes a particularly
dynamic driving style. That way, it accelerates the
S5 Coupé from 0 to 100 km/h in 4.9 seconds and
the S5Cabriolet in 5.4 seconds.
S engine:
More dynamics. More power.
