Conversation-piece looks, great engines, fine finish, solid feel, road-holding, well-engineered roadster hood, monstrous Z4 M
Looks aren't to everyone's liking, limited stowage space, hard ride in some versions
Intriguing-looking sports car that's a massive step up from the Z3, but keen drivers will still prefer the Porsche Boxster or Cayman.
The Z4's bodyshell is far stiffer than the Z3's; the coupe, in particular, is ultra-rigid. The roadster's structure incorporates both the windscreen frame and the two rear roll-over bars into the main body structure.
Four airbags are standard, as are systems to help avoid accidents: anti-lock brakes, stability control, traction control, plus clever touches such as brake drying and brake pre-tensioning. The run-flat tyres let you drive for up to 90 miles with no air in them provided you don't exceed 50mph and a tyre pressure monitor lets you know there may be a problem even before the tyre has lost its air. There is no spare wheel.
The doors have deadlocks and an immobiliser is built into the remote central locking and alarm system.
