Neither the NHTSA (National Highway Traffic Safety Administration) nor the IIHS (Insurance Institute for Highway Safety) have yet crash-tested the 2012 BMW Z4.
Standard safety equipment includes dual front airbags; seat-mounted head and thorax airbags; pop-up roll hoops that deploy in a rollover; stability and traction control; brake drying function for better wet stopping; hill-start assist; active cruise control; and anti-lock brakes.
Optional safety upgrades include automatic headlamps, park distance control, and BMW Assist service with Bluetooth. Advanced features like lane departure warning, rearview camera, and blind spot monitoring aren't available, however.
Compared to many roadsters, the Z4's visibility is impressive, with large side windows and minimal rearward obstructions--though with the top up, it can be more difficult to see rearward.
