Safety
In addition to 3-point safety belts with new belt tightening technology, BMW equips all 2009 Z4 models with driver and passenger air bags equipped with advanced technology dual-threshold and dual-stage deployment. Head/thorax air bags are integrated into the front and side of the seat backrests. The A-pillars (around the windshield) have been massively reinforced and there are fixed roll bars behind each of the passenger seats. All Z4 models feature run-flat tires and a tire-pressure-monitoring system. Standard active safety features in every BMW Z4 include anti-lock brakes (ABS), Dynamic Stability Control (DSC) with Brake Fade Compensation, Start-off Assistant, Brake Drying, Dynamic Traction Control (DTC), and Dynamic Brake Control.

Technology
Setting a new standard for convertibles, the 2009 BMW Z4 offers an innovative roof that allows unobstructed open-top motoring, yet seals tightly when closed to protect occupants from wind and weather. The aluminum roof offers expansive windows that are 40 percent larger on the side, and 52 percent larger in the rear than the windows on its predecessor, according to BMW. The overall increased visibility, and the extra-light color interior lining, add to the roomier ambience within the cabin, the manufacturer says. The roof, and the four powered windows, may all be dropped by either a switch in the center console or via the remote control key fob (when equipped with the optional comfort access system).

Like the BMW 3 Series convertible, the droptop Z4 Roadster also incorporates Sun Reflective Technology in its leather upholstery. The technology uses special highly-reflective leather on the seats, interior panels and steering wheel that BMW says will significantly reduce the heating effect of bright sunshine on those surfaces.
