Further development of BMW's comprehensive safety and security concept

At the core of the Z4 safety concept is the all-new, ultra-strong roadster body. Within this protective shell, new safety systems, such as Active Knee Protection, form critical elements of the user interface between the Z4 body and its occupants.

Features found in all current production vehicles are of course present:

• Dual-airbag front-impact Supplementary Restraint System
• Automatic safety-belt tensioners and force limiters
• Door-mounted side-impact airbags
• Battery Safety Terminal (automatically severs the battery/starter-cable connection in the event of a severe accident impact)
• Automatic shutoff of fuel pump after severe accident impact
• Central locking system encompassing doors, fuel-filler door, trunk and interior storage compartment
• Coded Driveaway Protection, a "rolling-code" immobilizer system that has proved highly effective in theft prevention.
