Passenger & boot space
How it copes with people and clutter
There’s certainly enough space in the Audi TT Roadster for tall adults. If you’re extremely long-legged, you might wish the driver’s seat slid as far back as that of the Z4, but the chances are that you’ll be more than comfortable. The TT Roadster’s interior width also helps you to feel less hemmed in than you might in other sports cars.
The door pockets are pretty small, but there’s a handy covered cubby in front of the gearlever, plus a decent-sized glovebox. The single cupholder between the seats is deep enough to securely hold a drink when you're cornering or braking. There’s another one right behind it, hidden under a lid.
The TT Roadster’s boot is quite a bit smaller than the fixed-roof TT’s and has a fairly small aperture. And while its load bay is relatively broad and square, it’s also rather shallow by roadster standards. Carrying the weekly shopping won’t present any problems but accommodating anything tall will. A set of golf clubs is also out of the question.
Overall, the Z4 beats it for not only usability but also sheer capacity, and, as with the TT Roadster, its total volume is unchanged whether the hood is up or down.
