The 911 GT2 | Safety
Bodyshell structure.
The 911 GT2 complies with all
statutory requirements worldwide
in respect of frontal, side,
diagonal and rear impact
protection.
The reinforced bodyshell contains
a highly resilient passenger
cell offering exceptional crash
protection. At the front of the
car, the cell is protected by a
patented system of longitudinal
and transverse members (1). In
the event of an accident, energy
is absorbed by three separate
load paths, one above the other,
which disperse the force of
impact and minimise deformation
of the passenger cell.
Additional features include an
extremely rigid bulkhead cross-
member (2) made from super
high-strength steel. This element is
designed to absorb impact forces
from the longitudinal members and
thus protect both front footwells. In
a minor collision, a system of easily
replaceable impact absorbers
(3) prevents costly damage to the
underlying bodyshell structure.
The reinforced doors (4) make
an increased contribution to
the overall rigidity of the car. An
additional load path (5) is used to
channel energy through the upper
part of the shell and thus further
protect the passenger cell.
In 1985, we began using super
high-strength steel elements
inside each door to increase side
impact protection. On the 911 GT2,
this integral reinforcement is made
from tough yet lightweight
aluminium. By increasing the
proportion of aluminium alloys
and high-strength steel, we’ve
also improved the power-to-weight
ratio. In all, approximately 20 %
of the 911 GT2 is made from
aluminium.
Another important but perhaps
less obvious safety feature is the
high-quality surface protection.
More than 30 years ago, we
became the first manufacturer in
the world to use a hot-dip gal-
vanised steel shell. This exacting
process is fundamental to the
legendary durability of our cars. It
also ensures a consistently high
standard of crash protection, even
after many years on the road.
