A6 Allroad Engines

Engines
Thanks to Vorsprung durch Technik, making the choice between 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 but, as a rule of thumb, the higher your mileage, the more economical a diesel will be.

TFSI: Direct injection petrol and supercharging combined
Supercharging. It's the innovation that powered the legendary Auto Union racers to win after win back in the 1930s, and it's still proving its worth today. It's what enables the A6 allroad's 3.0 TFSI engine to produce an exceptional 290PS of power, 420 Nm of torque and better all-round performance than an equivalent twin-turbo.

The 3.0 TFSI also achieves lower fuel consumption and more power than a conventional petrol engine. Fuel is injected into each cylinder individually, at very high pressure, which leads to greater efficiency. All while producing a lower level of CO2 than you might expect, meaning that the A6 allroad 3.0 TFSI already meets the proposed EU 5 emissions standards.

TDI Explained
TDI: High economy diesel, low emissions, superb power
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, 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 engine's capabilities while simultaneously reducing nitrogen oxide emissions.

TDIe. The 'e' is for efficient.
Audi is committed to reducing CO2 emissions from its vehicles and continuously develops new technologies to save you fuel. Find out more about the most fuel-efficient Audi A6 ever, by clicking the link below.

Racing Heritage
A proud racing pedigree
Over 70 years of successful competitive motor racing, we've learnt a lot about building high-performance, class-leading cars. But the knowledge we've built on the track doesn't just stay there; a surprising amount of thoroughbred racing technology finds its way into our production cars. From the ergonomic design of the cockpit to the power of the engine, there's racing pedigree in every Audi.
