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 vehicle weight saving of up to 65 kg
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 com ­
posite rigidit y, an increase in dynamic
torsional stiffness of up to 25 % compared
with that of the previous model, and
even
sportier handling despite a further
improvement in the weight to power ratio.
The longer wheelbase improves comfort
as well as straight ­line accuracy and
driving stabilit y at high speeds and in
fast corners.

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.

The 911 Carrera models are equipped

as standard with Bi ­Xenon headlights
including a headlight cleaning system
and dynamic range control. With dipped
or main beam, the road ahead is
illuminated more uniformly.
The LED front light units incorporate
direction indicators, daytime running
lights and position lights.
Automatic headlight activation is also
included as standard. The moment it gets
dark, the daytime running lights switch
off and the dipped beam headlights
switch on automatically.
Cut ting edge LED technology is also
used for the taillights, the high ­level third
brake light, the licence plate illumination,
the rear direction indicators, the rear fog
light and – on all ­wheel ­drive models –
the rear light strip. LEDs provide bet ter
illumination and respond more quickly
to driver input. In the event of sudden
braking, the adaptive LED brake lights
begin to pulsate. If the vehicle is braked
to a halt, the hazard warning lights will switch on automatically, alerting following
traffic more quickly to a critical situation.
The lighting system features an automa­
tic
switch
­off and the ‘Welcome Home’
function. It ’s good to know what ’s around
the next corner or on the way to your
front door.
Porsche Dynamic Light System (PDLS).
The Porsche Dynamic Light System
(PDLS) is available as an option.
Its dynamic cornering light function
swivels the headlights towards the inside
of a bend, based on steering angle and
road speed, in order to illuminate more
of the road at tight bends and turns.
Put simply, the road ahead is illuminated
the moment you enter a bend.
The system also of fers speed ­sensitive
headlight range control. With adaptive
light systems, it is possible for the maxi ­
mum range of the dipped beams to be
increased as a function of the speed of

automatically in t wo stages. Stage 1 is
the basic position for driving in cit y traffic,
for example. Stage 2 is designed for
driving at faster speeds, such as on the
motorway. Above 80 mph, the range
is adapted again.
Another feature of PDLS is the adverse
weather function, activated whenever the
rear fog light is switched on. It reduces
the effect of reflection phenomena in
poor visibilit y conditions to avoid the risk
of the driver being dazzled.
