The vehicle architecture, with its wide
track at the front axle and the low roof
line, lends the front of the 911 a dynamic
appearance that is both sport y and
elegant. It has also helped us to achieve a
low drag coefficient of 0.29 for the
9 11 C a r r e r a .
Fit ted as standard, the Bi-Xenon head -
lights have the familiar oval-shaped
surrounds for classic appeal and reveal
their technically impressive inner
workings. LED main headlights including
Porsche Dynamic Light System Plus
(PDLS +
) with dynamic cornering lights,
speed-sensitive headlight range control
and dynamic main beam are available
as an option.
The indicators, daytime running lights
and position lights are all LEDs and are
integrated into the separate front light
units. Their slimline design contrasts with
that of the rounded headlights. Together
with the two integral air intakes, they
make the front of the 911 unmistakable. At the rear, every thing is clean and
sharp: the styling, the appearance and
the effect. This is due not least to the
distinct lines and narrow LED taillights
which accentuate the horizontal
contouring of the rear. The illuminated
rear light strip on the all-wheel- drive
models further enhances the effect. One unmistakable Porsche feature
is the stainless steel tailpipes. On the
S models, t win tailpipes are fit ted on
both sides. The wide rear spoiler is
extendable, acting to reduce lift in all
driving situations and further increase
driving stability.
The 911 Carrera models and the
911 Carrera S models are equipped
as standard with 19-inch and 20 -inch
wheels, respectively. Their large
dimensions enhance the sporty presence
of the 911. The t yres have a large rolling
circumference for improved comfort and
performance. Even the logo on the rear has an impor
-
tant function to perform. It is, after all,
the hallmark of the Porsche identity.In summary, form always follows function.
As a design principle, it couldn’t be
more simple, but it ’s what makes the
9 11 a 9 11 .

Front and rear axles.
The independent suspension at the front
features a light weight spring-strut axle
with longitudinal and transverse links and
cross members that have been refined
for stiffness. Each front wheel is precisely
located, ensuring excellent directional stability, superior handling and reduced
pitching under braking, and the wide
track optimises turn-
in.
The rear axle is equipped with a
motorsport- derived multi -link suspension
and chassis subframe. Refined axle
kinematics for improved longitudinal
damping reduce acceleration squat and increase comfort. Light weight spring
struts further enhance agilit y.
The high proportion of aluminium used in
the construction of the axles reduces the
weight of the vehicle and of the unsprung masses, helping to improve fuel economy,
comfort and agility.

Engineered design.
The innovative bodyshell of the 911 fulfils
t wo structural design requirements: first,
excellent driving dynamics due to the
body’s extremely high rigidit y; second, a
low vehicle weight primarily as a result of
the intelligent lightweight construction.
To meet the second requirement, we
employed state -of -the- art techniques for
combining various materials in order
to utilise specific material properties
exactly where they are needed.
For the bodyshell, therefore, we used
very thin, but nevertheless extremely
rigid, sheets of steel. Aluminium and magnesium were used extensively in
areas such as the roof, underbody, front
end, doors, rear wings and engine com
-
partment and luggage compartment lids.
Magnesium, which is a particularly light -
weight material, was also selected for
the cockpit and centre console support
beam and, in the Cabriolet models,
the hood shell elements. Such material efficiency is key to
reducing the overall weight and, as a
result, fuel consumption of the vehicle.
For the driver, this intelligent blend of
materials reduces the weight of the
vehicle and offers a high level of comfort
thanks to excellent vibration-damping
characteristics and particularly high
composite rigidit y, a high degree of
dynamic torsional stiffness, and
especially sporty handling.
The long wheelbase improves comfort as
well as straight-line accuracy and driving
stabilit y at high speeds and in fast
corners.
