The 911 | Safety
911 Carrera S Cabriolet 911 Targa 4S
Passive safety in the 911 Carrera Cabriolet
and 911 Targa 4 models.
No need to lose your cool here, either.
Despite their modest weight,
the torsional rigidity and flexural
strength of the 911 Carrera
Cabriolets are exemplary. Body
flexing is minimal, even on uneven
roads. Additional brace members
at each of the rear wheel arches
provide additional reinforcement
of the bodyshell.
Increased protection if the car
overturns is provided by an
automatically deploying roll-over
protection system (Fig. p. 93).
Two spring-loaded roll-over bars
are located behind the rear seats.
The roll-over sensor continuously
monitors changes in body tilt,
longitudinal and lateral accelera-
tion and contact with the road
surface. In an emergency, it
deploys the roll-over bars within a
fraction of a second.
The 911 Targa 4 models offer
excellent body rigidity – despite
the large glass area. The roof
bars, with optimised structure and
strength, limit torsion to a mini-
mum on uneven road surfaces.
Additional stability is provided
by a cross-member integrated
between the glass roof and the
rear screen. The glass roof is
made of laminated safety glass,
the opening rear window of single
pane safety glass.
Naturally, all 911 Carrera Cabriolet
models and 911 Targa 4 models
are fitted with Porsche Side
Impact Protection (POSIP) as
standard.
For open-top sports driving, even
in changeable weather conditions,
nothing stands in the way of
relaxed driving pleasure. Another
distinct advantage of passive
safety.
