05/09/2008 23:40. Our spies have caught the fastest TT yet! And the R8s baby brother will be badged the RS.

The RS will have a sportier look than the other TT models thanks to a lower ride height, R8-style bodykit, chrome wing mirrors and enlarged oval exhaust pipes.

The wheelarches have also been widened to make room for 19-inch alloys. An arched rear spoiler and the addition of RS badges will complete the look.

It promises to be a real alternative to the Porsche Cayman when it goes on sale later this year.

The TT RS will use a 2.5-litre in-line five-cylinder petrol unit, its first five-pot engine in ten years. Early reports indicate that Audi will boost performance to a hefty 260kW using twin sequential turbochargers.

All this grunt will be channeled through Audi's permanent all-wheel-drive quattro system and a six-speed manual box, though the DSG dual-clutch system will also be available as an option.

Inside, the coup gets a pair of sculpted racing seats, a trademark flat-bottomed steering wheel and drilled aluminium pedals. Other features include Magnetic Ride adaptive dampers and the latest version of Audis MMI cabin control system with a touchscreen interface.
