A choice of 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.

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

The A3 1.6 TDI is the most fuel-efficient Audi ever returning a quite remarkable 68.9mpg on a combined cycle. Yet it can still accelerate from 0-62mph in 11.4 seconds (11.7 on the A3 Sportback), has a top speed of 121 mph and CO2 emissions of just 109 g/km.

The turbocharger has variable turbine vane geometry to help produce higher torque and stronger pulling power. And sophisticated air-flow control also contributes to the engine's capabilities while simultaneously reducing nitrogen oxide emissions.

TFSI Explained
TFSI: Direct petrol injection and turbocharging combined

TFSI technology unlocks superior power, more dynamic performance and better economy from petrol engines.
For example, the 1.4-litre version of the TFSI engine features great economy and, thanks to its turbocharger, manages to deliver an amazing 200Nm of torque and a top speed of 126mph. Quite simply, it feels as though it's a bigger engine than it is.

You'll notice enhanced driving enjoyment with spontaneous and dynamic torque build up. In turn, this encourages you to change up earlier so you don't feel the need to rev the engine so much, promoting greater efficiency.

This impressive technology hasn't gone unnoticed. The 2.0 litre version of the TFSI engine has been voted "International Engine of the Year" by a panel of 64 motoring journalists from over 30 countries. They cited it as "A blend of performance and efficiency. An example to all engine manufacturers."

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.
