Details of 2010 Audi TT RS

Last year, Audi has taken the wraps off several variants of its sporty TT, including TT-S, 2.0L TDI diesel-powered TT and the entry-level 1.8L TFSI model. And at the 2009 Geneva Motor Show, we see the performance RS version of the TT, which is simply called Audi TT RS. The TT RS range has two models, they’re TT-RS Coupe and Roadster.

The TT RS range is powered by Audi's new 2.5-litre five-cylinder turbo engine with FSI direct petrol injection. It makes maximum power of 340hp (250kW) and peak torque of 450Nm (332 lb ft) between a wide band of 1,600rpm and 5,300rpm. This power and torque is sent through to all four wheels via Audi's quattro permanent AWD.

Performance, according to Audi, confirms the TT RS as the fastest in its class. The Coupe fires off the line to 100km/h in 4.6 seconds while the Roadster does it in 4.7 seconds. Top speed is limited to 250km/h in both cars but can be increased to 280km/h if requested. The hard top weighs in at 1,450kg (3,197 lbs) while the Roadster is 60kg (132 lbs) dearer because of all the extra equipment needed to operate the canvass roof.

Average fuel consumption is 9.2 litres per 100km (25.57 US mpg) for the Coupe and 9.5 litres per 100km (24.76 US mpg) for the Roadster.

The standard wheel size is 18-inch with 245/40 tyres but customers can specify the bigger 19s or 20s for their baby. A standard sports suspension lowers the car by 10 milimetres while the optional magnetic ride adaptive damping system offers Comfort and Sport characteristics. The rear features a diffuser and a stationary spoiler. There is an optional one that retracts and extends. All models are fitted with a six-speed manual and ventilated disc brakes with black four-piston aluminium callipers and diameters of 370mm at the front and 310mm at the rear button, which alters throttle response and also opens a flap in the left exhaust tailpipe to increase the rumble. The standard electronic stability software has been replaced with a more sporty version that is more forgiving to sideways action and can also be switched off completely for maximum fun.

The interior is laid out in leather and Alcantara. It also features heated sports seats, brushed aluminium inlays and a flat-bottomed multifunction sports steering wheel.

The TT RS Coupe will be priced at €55,800 and the Roadster at €58,650 when they are launched this summer in Europe.
