PORSCHE 911 TURBO 2004 4.G Information Manual

The new 911 Turbo is also
available with an optional high-
performance braking system:
the Porsche Ceramic Composite
Brake (PCCB). Successfully
tested in the toughest endurance
racing, this unique technology
has been further refined for even
greater road performance.The key components in PCCB
are the moulded ceramic discs
(front/rear diameter: 380 mm/
350 mm). The larger front discs
provide greater leverage and
therefore better brake performance.
Thediscsaremadefrom a
specially treated carbon-fibre
compound that is silicated in a
high-vacuum process at 1,700 ºC.
The resulting material is not
only much harder than metal, it
is also more resistant to heat.
Even at high temperatures, the
thermal resistance of the PCCB
disc ensures excellent dimensional
stability. The ceramic material is
totally resistant to corrosion and
offers excellent acoustic damping
properties.The pads are mounted in six-
piston monobloc aluminium
fixed calipers at the front, with
four-piston units at the rear.
The resulting brake forces are
not only extremely high, they are
also exceptionally consistent.
The pedal response is fast andprecise, with only moderate input
required.
The key advantage of PCCB is the
total weight saving over comparable
metal discs of approximately 50 %.
As well as enhancing performance
and fuel economy, this represents
a major reduction in both the
unsprung and rotating masses.
This, of course, produces
additional benefits in terms of
comfort and road-holding on
uneven road surfaces as well as
general handling and agility.

from your Porsche Centre.

PCCB
Porsche Ceramic Composite Brake (PCCB).
When it comes to developing new brake technology,
nothing holds us back.

The 911 Turbo easily complies
with all statutory requirements in
all markets 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 apatented 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.The upper section of each door
features additional reinforcements
(4) which enhance the rigidity of
the car. An additional load path
(5) is used to channel energy
through the upper part of the shell
and protect the passenger cell.
In 1985, Porsche began using
super high-strength steel elements
in its door design to provide
greater occupant protection. On
the new 911 Turbo, this integral
reinforcement is made from
robust yet lightweight aluminium.
By increasing the proportion ofaluminium alloys and high-strength
steel, we’ve also increased the
car’s power-to-weight ratio. No less
than 20 % of the new 911 Turbo
is made from aluminium.
As you would expect, the entire
bodyshell structure receives
a highly effective anti-corrosion
treatment. Thirty years ago,
Porsche became the first manu-
facturer in the world to use
a hot-dip galvanised steel shell.
This exacting proces s is
absolutely 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. To underline our confidence
in this exceptional build quality,
the 911 Turbo comes with a
ten-year anti-corrosion warranty,
three-year paint warranty and
two-year warranty on the car as
a whole.

Adding strength, reducing weight.
Additional features include an
ultra-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 the front footwells. In a
minor collision, a system of easily
replaceable impact absorbers
(3) prevents costly damage to the
underlying bodyshell structure.

Complementing the front airbags
is the latest generation of Porsche
Side Impact Protection (POSIP).
This comprehensive package
includes two additional airbags for
each front seat: a thorax airbag
in the side of each backrest,
and a head airbag located in each
door. Each side airbag has anapproximate volume of 8 litres,
ensuring maximum protection
over the entire seat adjustment
range. Also incorporated within
the POSIP package are side-
impact protection beams in the
doors.Other standard features include
integral head restraints, an
energy-absorbing steering column,
height-adjustable three-point seat
belts with pre-tensioners and
force limiters, energy-absorbing
structures in the dashboard area
and flame-retardant materials
throughout the interior. The new 911 Turbo has a unique
passive protection system
featuring six separate airbags.
The full-size front airbags for
driver and front passenger have
a two-stage inflation capability.
With this technology, the
deployment of each airbag is
dependent on the force and
nature of the accident (e.g.,
frontal or diagonal impact). In
a low-speed crash, the airbag
is only partially inflated, thereby
minimising discomfort to the
occupants.
The airbag control unit is located
in the centre tunnel where it
receives additional information
from a pair of impact sensors near
the headlights. This arrangement
enables faster and more accurate
evaluation of impact forces in the
event of a crash.
