It's a case of close but no cigar for both Porsche's Cayman and Boxster and also BMW's M2 when trying to match Audi's interior quality. The Alpine A110 isn't even close. The interiors of lesser TTs, with their soft plastics, chrome accents and beautifully damped switches, are already mightily impressive, and there's more of the same in the TT RS. It's the little details, such as climate controls that are integrated stylishly into the air vents, that make it feel special but also very easy to use.
Audi's Virtual Cockpit is fitted as standard behind the steering wheel, where you'd normally expect to find analogue instrument dials. Its 12.3in digital screen displays your speed and engine revs while also acting as a hub for all of the infotainment functions, such as the stereo, Bluetooth and sat-nav.
The whole thing is easy to use while you're driving, unlike the touchscreen systems in the Cayman and A110. Instead of struggling to hit icons with your fingers, you control the TT RS's system by twisting and pressing a big rotary dial between the front seats, with some handy shortcut buttons available to take you directly to specific functions. It's a similar system to the M2's iDrive, and works almost as well. Apple CarPlay and Android Auto smartphone mirroring are standard in the TT RS, which means you can access Waze and Google Maps through the infotainment screen.
The seating position isn't ideal for a sports car, though. There's lots of adjustment to the steering wheel and the sports seats, but the pedals feel too close to you and the seat is set relatively high – more like that of a hatchback. Both the Boxster and Cayman have lower-slung seats and pedals that allow your legs to stretch out straighter, which is more comfortable and more sports car-like.
The view forward is good and judging where the nose of the car ends is pretty easy. However, both versions of the TT RS suffer poor rear visibility — the Roadster due to the restrictions its fabric hood and the Coupé because of its sloping rear roofline. Front and rear parking sensors are standard, though, and a rear-view camera is on the options sheet. Effective LED headlights are standard, too, which you can upgrade to even better adaptive 'Matrix' units.
