Passive safety: airbags.
Each of the full-size airbags is
inflated in two stages, depending
on the severity of an accident.
In less serious accidents, the
airbags are only partially inflated,
thereby minimising discomfort
for the occupants. Also fitted as
standard is Porsche Side Impact
Protection (POSIP). It comprises
74
side impact protection elements
in the doors and two airbags
on each side. An integral thorax
airbag is located in the seat back-
rests, while each door panel
contains a head airbag. With each
having a volume of approximately
8 litres, these airbags offer
excellent protection in the event
of a side impact.
Other passive safety features
include headrests integrated into
the seat backrests, an energy
absorbing steering column,
three-point seat belts, front seat-
belt pretensioners and force
limiters, energy-absorbing
elements in the dashboard
and flame-resistant materials
throughout the interior.
