A6 Avant Engines & Transmissions

Engines

A choice of engines

Thanks to Vorsprung durch Technik, making the choice between the Audi A6 Avant’s petrol and diesel engines isn’t as straightforward as it used to be. Engines of both fuel types offer improved power, lower emissions, sporty performance and increased efficiency. Do you prefer the high-torque pulling power of a diesel or the increased response of a petrol engine?

The choice is yours.

Petrol

TFSI explained

TFSI technology available in the Audi A6 Avant unlocks superior power, more dynamic performance and better economy from petrol engines. In fact, compared with many naturally aspirated 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 of the A6 Avant.

Diesel

TDI explained

A dedication to pioneering technology has brought Audi peerless expertise in turbocharged diesel engines. All Audi TDI engines are equipped with common rail and piezo injectors to achieve smooth, efficient and quiet combustion. Diesel fuel related emissions are also significantly reduced thanks to a diesel particulate filter, fitted as standard to all A6 Avant diesels, which filters out almost all soot particles contained in the exhaust gas.

The turbocharger has variable turbine vane geometry to help produce higher torque and greater power for the cubic capacity of the engine. And sophisticated air-flow control also contributes to the A6 Avant’s engine’s capabilities while simultaneously reducing nitrogen oxide emissions.
