Audi is celebrating the production of the 500,000th TT with the creation of a new one-off model, the Audi TTS Limited Edition.

Just 500 will be made, with only 120 coming to the UK.

The TTS Limited Edition is powered by a 2.0-litre TFSI engine developing 272PS and 350Nm of torque, with a choice of six-speed manual or six-speed S tronic twin-clutch transmission.

The latter can accelerate to 62mph in 5.3 seconds, has an electronically-limited 155mph top speed, and can return 36.7mpg with CO2 emissions of 179g/km.

The TTS LE is available in both Coupe and Roadster forms, priced from £38,860 and £42,320 respectively.

Coupe models are available in Nimbus Grey, with the Roadster in Imola Yellow, while both wear the fixed rear spoiler from the TT RS.

Both receive extra equipment over the standard TTS model to the value of £5,665, including 19-inch alloy wheels, grey leather upholstery, DVD satnav, BOSE sound system, rear parking sensors, cruise control, automatic headlights and wipers, interior light package and a numbered plaque on the door insert.

The Audi TTS Limited Edition is available to order now.
