As we mentioned in the driving section, the Z4 is large for a two-seat sports car. Now, this might make it difficult to manoeuvre in town and down tight roads, but the upside is a generous-sized cabin. The wide interior means you feel less hemmed in than in many roadsters, and the highly adjustable seat allows you to sit nice and low, so head room is not a problem when the roof is closed.
The door pockets are also a good size, there’s a handy covered cubby in front of the gearlever where you can wirelessly charge your phone, and there’s a decent-sized glovebox.
Most impressive of all, however, is the boot capacity. At 281 litres, it is larger than those of the Audi TT Roadster, Porsche Boxster and Alpine A110. And unlike its hard-top predecessor, that figure remains unchanged whether the roof is open or closed. That means you can happily throw your golf clubs in the boot and drive to your local driving range with the roof down.
