Inside the 18″ wheels there are big brakes to keep the speed in control.
The internally ventilated disc brakes measure 370 millimeters in diameter in the front and 310 millimeters in the rear.
Black four-piston brake calipers with RS logos keep the friction rings in place.
The electronic stabilization program (ESP) has a sport mode and can also be switched off partially or entirely.
The sport suspension in the RS lowers the vehicle by 10 millimeters.
Adaptive shock-absorber technology, called Audi magnetic ride, is available optionally.
Not just by its performance, but TT RS can be easily recognised even when it is standing still.
Biggest attraction is of course the fixed rear spoiler, which maximises downforce and ensures optimum aerodynamics. However, if you wish, and you want be boring, you can replace the fixed rear spoiler with a more discreet version which raises and retracts automatically.
At the rear there are also broad diffuser that holds two large, oval, chrome-finished tailpipes, one on the left and one on the right.
And if you have opt for a sports exhaust, then the tailpipes are finished in matt black providing even sportier soundtrack. Aluminium door mirrors, featuring LED side-turn indicators, are also part of TT RS’s styling and are bespoke to S and RS models.
At front we have enlarged air intakes and unique honeycomb grille with TT RS logo.
Inside the car everything is set to be driver-oriented.
The cabin is finished exclusively in black or silver, with brushed aluminium inlays and aluminium footrests.
As standard the TT RS comes with contoured and heated sports seats which provide excellent lateral support and are upholstered in Silk Nappa leather complete with contrasting stitching.
But if you wish for even more sportier feel, then you should can choose TT RS bucket seats, which are available as an option. These come in Fine Nappa leather with contrasting stitching in silver and with the discreet TT RS logo.
As well as the sports seats, also other areas of the cabin, like centre console, armrest and handbrake have been upholstered in leather.
The final touch is the multi-function, 3-spoke, flat bottomed leather steering wheel with TT RS badge.
