This computer-generated image shows how the top-of-the-range Audi TTRS could look when it is launched in late 2009 or early 2010.
The car is currently under development, but reports suggest it will be powered by a 3.2-litre engine with 340bhp, making it comfortably the most powerful TT derivative on sale.
It will also make it more powerful than the BMW Z4 M coupe, which it is set to rival.
As with the 268bhp TTS, which is due to go on sale later this year for around £35,000, buyers will have the choice of either a standard six-speed manual or a seven-speed version of Audi's S-Tronic double-clutch gearbox. Four-wheel drive will be fitted as standard.
The TTRS is expected to cost from £45,000.
