A3 Brochure - Audi

In just a few seconds you will understand why.
In FSI® technology, the fuel is injected directly
into the combustion chamber and atomised into
a fine spray. This way, the fuel – metered to
almost droplet precision – can be called upon the
millisecond that the engine requires it. This can
contribute to better use of the fuel and thus to
reduced fuel consumption.
The A3 models employ TFSI technology. This
combines the advantages of FSI – efficiency and
dynamism – with a turbocharger, which ensures
even better power delivery. The 1.4 TFSI engine
with 90 kW in the A3 and A3 Sportback will get
you economically yet powerfully to your destination.
Its lightweight aluminium engine block
saves weight and allows you to reduce fuel consumption.
The 1.8 TFSI engine with 132 kW in the A3 and
A3 Sportback works with the Audi valvelift
system and intelligent thermal management.
More torque is generated at low engine speed by
switching between two exhaust cam contours.
You feel the effect directly: the engine reacts
more quickly and accelerates with S tronic from
0 to 100 km/h in 7.2 seconds in the A3 and in
The fuel consumption and CO₂ emission figures can be found from page 118 onwards.

7.3 seconds in the A3 Sportback. The Audi valvelift
system also helps you to save fuel and reduce CO₂
emissions. In addition to direct fuel injection, the
1.8 TFSI (132 kW) uses indirect injection, which
makes the part load range even more efficient.
The turbochargers of both engines have an
electric wastegate actuator which regulates the
charging pressure particularly quickly and
precisely. In addition, the exhaust manifold has
been integrated in the water-cooled cylinder
head, shortening the engine warm-up period and
reducing the exhaust gas temperature. All these

with a sporty driving style. It goes without
saying that both engines comply with the EU5

The 2.0 TFSI engine in the Audi S3 even meets
the stringent requirements of the EU6 emission
standard. Its 221 kW power it with S tronic from
0 to 100 km/h in 5.1 seconds. This engine also
works with the Audi valvelift system, as you will
notice through the direct, agile response. And the
integrated exhaust manifold saves space and also
helps reduce consumption.
