TT Roadster Engines

Engines
A choice of engines
The TT Roadster comes with a choice of powerful turbocharged engines and, unusually for such a performance car, a 2.0 litre diesel option too.

And, thanks to Vorsprung durch Technik, making the choice between petrol and diesel engines isn't quite 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 that will take you to 62mph in 7.7 seconds, yet still return over 50 mpg. Or would you prefer the raw power of a 3.2 litre V6?

TFSI Explained
TFSI: Direct injection petrol and turbocharging combined
TFSI technology unlocks superior power, more dynamic performance and better economy. In fact, compared with naturally aspirated V6 engines, TFSI delivers the same sporty performance but with four cylinders and 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.

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 significantly reduced thanks to a diesel particulate filter fitted as standard.

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.

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.
