Using FSI® technology, the fuel is injected directly into the combustion chamber and sprayed into a very fine spray. In this way the fuel, which is measured with absolute precision, can be used in the same millisecond required by the engine, which contributes to increase its efficiency.
Fuel Consumption and Emissions Data:
Combined fuel consumption: 5.2 - 5.6 l / 100 km Combined CO2 emissions: 120 - 130 g / km
The Audi A3 employs TFSI® technology. The defining characteristic of this technology is that it combines the advantages of FSI® technology (efficiency and dynamism) with turbocharging, which guarantees even greater power. The 1.4 TFSI engine with 122 hp (90 kW) will efficiently drive you to your destination. Its lightweight aluminum engine block saves fuel and weight.
The 1.8 TFSI engine with 179 hp (132 kW) works with the Audi valvelift system and the intelligent thermal management system. By exchanging between two exhaust cam contours a higher torque is generated at lower engine speeds: an effect that you can directly sense. The engine reacts faster and accelerates from 0 to 100 km / h in 7.2 seconds with the S tronic®. The Audi valvelift system also helps reduce fuel consumption and CO2 emissions. In addition to direct fuel injection, the 1.8 TFSI engine uses indirect injection, which makes the partial load margin even more efficient.
The turbochargers of both engines have an electric discharge valve that regulates the load pressure with special speed and precision. In addition, the exhaust manifold has been integrated into the water-cooled cylinder head, which reduces the temperature of the exhaust gases.
All these measures reduce the consumption, especially when the vehicle circulates with a style of sport driving. Both engines comply with EU5 emissions regulations.
