It doesn’t matter 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 Jaguar F-Type even harder than it sells lesser Audi 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.
Sports car interiors so often look and feel like afterthoughts – the bit that manufacturers get to last, after they’ve spent most of the budget on (and traded off occupant space for) an expensive mid-mounted engine and then invested in lightweight suspension and a flighty weight-saving body.
But the TT’s cabin has never felt like that, and the new TT RS’s in particular surrounds you with swish, perfectly finished materials and tactile leather and Alcantara and greets you with wonderfully neat, solid and appealing switchgear.
