Audi is to produce a special edition run of its TT sports car, to celebrate the model selling 500,000 examples globally. Only 500 will be produced, with 120 making their way to UK showrooms.

The limited edition TTS variant will be available in both coupe and convertible guises, priced at £38,806 and £42,320 respectively.

The model is mechanically unchanged from the standard TTS, meaning you get a 268bhp 2.0-litre turbocharged engine mated to Audi’s signature Quattro four-wheel-drive system, with a choice of six-speed manual or seven-speed twin-clutch automatic.

With the optional automatic gearbox, the TTS will manage the 0-62mph sprint in 5.3 seconds and will go on to an electronically limited top speed of 155mph – and yet will still return an official combined 36.7mpg.

Where the limited edition differs from the regular TTS is in the claimed £5,665 worth of additional styling upgrades available for the £2,815 premium over the standard car. This includes a fixed rear spoiler such as that seen on the more powerful TTRS, as well as larger 19-inch alloys, which complement the TTS body-kit and quad exhaust pipe arrangement, xenon headlights and LED daytime running lights that are fitted as standard.

Inside, the seats are slathered in a unique grey leather, offset with exposed yellow stitching. The options list has been plundered, too, with DVD-based sat nav, BOSE sound system, cruise control and Bluetooth connectivity all making an appearance.

The limited edition in just two colours: Nimbus Grey for the coupe and Imola Yellow for the convertible.

It is rumoured that an all-new iteration of the TT is due to make its debut at the Geneva motor show in March. If you can’t wait that long you can search our classifieds for a used Audi TT here.
