Passenger & boot space
How it copes with people and clutter
If you're very long in the leg you'll find there's more room in the Z4 than an Audi TT Roadster or Porsche Boxster. It's wider than a TT inside, so you and your passenger won't feel overly cosy, but the TT has more head room. Still, the Z4 isn't exactly tight for head room, either.
The door pockets are also a good size and there’s a handy covered cubby in front of the gearlever where you can wirelessly charge your phone, plus a decent-sized glovebox for extra bits and bobs. The only issue is that the cup holders are mounted inside the central armrest, which means you have to drive around with the armrest open if you make a Starbucks or Costa pit stop. There’s also a small amount of storage behind the seats and a cargo net with just enough space to shove a coat or spare pair of shoes.
Most impressive of all, however, is its boot capacity. Not only is it larger than that of an Audi TT Roadster or Porsche Boxster, but its size remains unchanged whether the roof is open or closed. That means it'll easily fit your golf clubs, or, as our tests proved, five carry-on suitcases (that's the same number as a Volkswagen Golf). And, if you're worried that you'll need a back-up car to take your skis, for a small charge you can add a ski hatch in between the front seats for even greater convenience.
