Can you imagine a face without an expression?

Exterior design.
Every child recognises a 911, but can its
identit y be described in words? It can, by
looking more closely at the use of form,
proportions and contours. The roof line
tapers down into the rear. The wings are
higher than the front lid and, at the rear,
they add muscle. They give the 911 its
distinctive expression and leave you in
no doubt as to its temperament.
The overall appearance is low, wide and
sleek. Typically 911.
So, is every thing just the same as it has
been since 1963? Yes, and no. After all,
only those who change will remain true
to themselves – and we’ve changed. Our designers and engineers speak
guardedly about the 911 evolution.

Meanwhile, they continually manage to
take great strides forward with innova -
tions motivated by the principle that
these should be functional and perfectly
compatible. The result is a harmonious
overall concept that makes the new 911
a sports car fit for the 21st century.
To show you what we mean, we should
start by looking at the car’s exterior. The
wheelbase of the new 911 is 100 mm
longer for improved driving stability and
cornering dynamics. Overhang is now
shorter at the front and rear, making the
new 911 look even more compact. The sporty overall impression is emphasised
by the lower roof line and a wider track
at the front – 46 mm on the 911 Carrera
models and 52 mm on the 911 Carrera S
models. For improved aerodynamics, the
exterior mirrors are now mounted directly
on the doors. Increased agility is just one
of the results of all these refinements.
The silhouette is therefore typically 911
and t ypical in terms of its development,
which will now be described in more detail.

The new vehicle architecture, with a wider
track at the front axle and the lower
roof line, gives the front of the new 911
a dynamic appearance that is sport y
and elegant. Fit ted as standard, the new
Bi-Xenon headlights still have the familiar
oval-shaped surrounds for classic appeal
and reveal their technically impressive
inner workings. The Porsche Dynamic
Light System (PDLS) with dynamic
cornering lights and speed-sensitive
headlight control logic is available
as an option.
The direction 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 new 911 unmistakable.
At the rear, every thing feels sharper: the
styling, the appearance and the effect.
This is due not least to the distinctive
profile edge and new LED taillights, their
stretched design accentuating the horizontal contouring of the rear.

The characteristic reflector units have
been positioned lower down but are
still recognisable, particularly at night.
The stainless-steel tailpipes have been
rest yled. On the 911 Carrera S models,
t win tailpipes are fit ted on both sides.
One new feature is the wider, extendable rear spoiler, which reduces lift in all

driving situations and increases driving
stability.The 911 Carrera and the 911 Carrera S
are equipped as standard with 19-inch
and 20 -inch wheels
respectively. One
inch larger than
those on the respective
previous model, they enhance the sport y
presence of the new 911. Newly
developed t yres with increased
rolling circumference improve both
comfort and performance.
In summary, form always follows
function. As a design principle, it
couldn’t be more simple, but it ’s
what makes the 911 a 911. It ’s also how we have managed to
achieve a very low drag coefficient of
just 0.29 on the Coupe models and
0.30 on the Cabriolets.
Even the logo on the rear has an important
function to perform. It is, after all, the
hallmark of the Porsche identity.

| Chassis and body
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.
