TFSI® in the new Audi A3 Sportback.

More efficiently ahead.

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 Audi A3 Sportback employs 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 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 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® in 7.3 seconds from 0 to 100 km/h 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 engine warm-up period and the reducing the exhaust gas temperature. All these measures help to reduce consumption, particularly with a sporty driving style. It goes without saying that both engines comply with the EU5 emission standard.

Consumption and emission values:
Fuel consumption, combined: 5.6–5.3 l/100 km
CO2 emission combined: 130–123 g/km
