TFSI: Direct injection petrol and turbocharging combined

TFSI technology unlocks superior power, more dynamic performance and better economy from petrol engines. In fact, compared with many naturally aspirated V6 engines with more cylinders, TFSI delivers the same sporty performance but using 10 to 15% less fuel.

FSI and turbocharging technology work so well together because the evaporation of fuel in the combustion chamber cools the intake air giving higher compression, improved engine efficiency and, in turn, lower CO2 emissions.

Introducing the Audi valvelift system

All petrol derivatives of the A5 also feature the Audi valvelift system. This innovation varies the valve lift between two levels which provides the car with better low-end torque and a more effective dynamic torque build up. The effect is a significant increase in engine efficiency, so you can get greater power and improved response from less fuel.
