Alongside the crash-optimised body, extensive passive safety systems ensure maximum protection. Depending on the seating configuration, four or five three-point belts with force limiters are fitted as standard. The Porsche Side Impact Protection System consists of side impact protection elements in the doors, and thorax airbags that are integrated in the side bolsters of the front seats. The side protection system is rounded off by curtain airbags covering the entire roof frame and side windows from the A to the C pillar. Classic full-size airbags and one knee airbag each for driver and front passenger are available at the front.
