Engineered design.
The new 911 fulfils two structural design
requirements thanks to its completely new
bodyshell: first, excellent driving dynamics
due to the body’s extremely high rigidit y;
second, a vehicle weight saving of up to
60 kg primarily as a result of the intelligent
lightweight construction.
To meet the second requirement,
we employed innovative and precise
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 100 mm 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 redesigned 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 wider track optimises turn-in.
The rear axle is equipped with a
motorsport-derived multi-link suspension
and chassis subframe. Refined axle kine -
matics for improved longitudinal damping
reduce acceleration squat and increase comfort. Light weight spring struts further
enhance agility.
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 new 911 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 rest yled 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 and the rear fog
light. 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 traf fic more quickly to
a critical situation.
The lighting system features an automatic
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

So does forward-looking technology.
Lights.the vehicle. PDLS takes care of this
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 130 km/ h (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.
