It doesn’t matter how familiar you are with a TT: it’s always a pleasant surprise to open the door of a sports car measuring less than 4.2 metres in length – that’s more than a foot shorter than a Porsche 911 – and find that there are back seats inside it, and behind them a good-sized and extendable liftback boot.
The TT RS’s rear seats are big enough only for very small occupants, and Audi knows it; there’s a yellow label on the inside of the passenger door warning you against even trying to get in if you’re more than five feet tall.
And yet the seats are useful, if not for people then for shopping bags or holdalls.
And if usability is going to sell any sports car, it ought to sell the TT RS next to strictly two-seat rivals such as the Cayman, Alfa Romeo 4C and Jaguar F-Type even harder than it sells lesser TTs against 2+2 rivals such as the Toyota GT86.
But the readily apparent material quality, sharply drawn style and dazzling technical sophistication of the TT RS’s cabin ought to sell the car harder still.
