In terms of safety equipment, the 2006 Porsche Cayenne Turbo S features six airbags: two front airbags and two thorax airbags for the driver and passenger, and two side-curtain airbags that stretch along both sides of the roof trim panel. This marks the first time Porsche has installed side-curtain airbags on any vehicle. They’re designed to inflate downward to protect passengers in the front and rear in the event of a side impact or rollover.
