2010 PORSCHE PANAMERA wheel size

· 22 ·· 23 ·
Concept | The Panamera model range
As you can see, we didn’t experi -
ment with the car’s design. We
stuck with our philosophy that form
should follow function. Nothing
else would have made sense.
Nothing else would have produced
a four-seater Porsche.
But how can you tell whether it
has the Porsche DNA? From the distinctive proportions and lines
on all models. The wings are
slightly higher than the bonnet
and, at the rear, they are distinctly
muscular and form the t ypical
Porsche shoulder line. The silhou
-
et te of the Panamera models is
therefore t ypically Porsche. It is
dynamic without being overbear -
ing, and exudes elegance rather than extravagance. In its class,
the total length of less than five
metres is to its advantage. The
front, shoulders, and rear all have
instantly recognisable Porsche
traits. Particularly striking are the
side air outlets behind the front
wheels – paying homage to
the Carrera GT. The result is a
timeless exterior, a spacious
interior and excellent aerody
-
namics: the Panamera S models
have a drag coef ficient of 0.29,
the Panamera models and the
Panamera Turbo 0.30.
A low, wide stance. A sleek roof -
line. The overall impression leaves
you in no doubt that these are true
sportscar proportions. Typically
Porsche. And yet, when you get
in, you’ll wonder how there can
possibly be so much room. We’ll
come to that on the pages that
f ol l o w.
Unmistakably Porsche and yet
characteristically Panamera is
the headlight design (p. 80). The
headlights on the Panamera Turbo
are supplemented by the Porsche
Dynamic Light System (PDLS)
(p. 83).
Position lights and day time run -
ning lights with LED technology
on all Panamera models add a
special touch.
The wheels are of classic sports -
car design: fine-spoked, light-
weight, and st ylish. Sizes range
from 18 inches to an optional
20 inches, and all the wheels pro -
vide a good glimpse of the brake
system. Just another example
of sport y st yling.
If you loved the road,
you wouldn’t dream of tarnishing it.

Performance | Chassis
Suspension.
The front axle has a wide-spaced
aluminium double wishbone
arrangement with an aluminium subframe. The wide spacing
bet ween the wishbones keeps the
forces in the wheel suspension
low for precision wheel guidance
and excellent handling. The rear axle is an aluminium
multi-link setup. This axle design
minimises the pitching of the body
under acceleration and braking.
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 and increase agilit y.
Steering and Servotronic.
Precise and direct: describes a
t ypical Porsche steering system
–
with variable steering ratio.
Around the straight ahead position,
such as during motorway driving,
the ratio is less direct with no loss
of agilit y or feedback from the
road. When the steering wheel is
turned further, the ratio becomes
more direct, allowing easier cor -
nering and parking.
Servotronic, a speed-sensitive
power-steering system, is available
as an option for all Panamera
models. At high speeds, the steer -
ing is firm and responds with
extreme precision while steering comfort remains as high as you
would expect. At low speeds,

Servotronic’s ratio adjusts for
easy manoeuvring and parking.
Wheels and Tyre Pressure
Monitoring (TPM).
The new Panamera and Panamera 4
models are fit ted as standard with
18-inch Panamera wheels, the
Panamera S and 4S with 18-inch
Panamera S wheels. All wheels
are light weight alloys featuring a
classic sport y design. Tyre sizes
245/50 ZR 18 and 275/45 ZR 18
are fit ted to the front and rear,
respectively. The Panamera Turbo is equipped
with 19 -inch Panamera Turbo alloy
wheels as standard. The t yres
are slightly wider to cope with the
increased power output of this
model: 255/45 ZR 19 at the front,
285/40 ZR 19 at the rear.
A selection of 18-inch to 20 -inch
wheels is available from our range
of options (p. 147).
19-inch all-season t yres are
offered as an alternative at no
extra cost for all Panamera
models with standard or optional
19-inch wheels. A low-rolling
resistance version of these t yres
is available as an option*. The
three
main components of the
Panamera Turbo front axle
Panamera Turbo rear axle 19 - inch Panamera Turbo wheel
18 - inch Panamera S wheel
18 - inch Panamera wheel
t yre – the rubber compound, the
tread pat tern and the architec -
ture of the t yre substructure –
have been optimised to minimise
roll resistance and thus improve
fuel economy, with no ef fect on
comfort or performance compared
with the regular 19 -inch all-season
t yres.
For increased comfort and safet y,
Tyre Pressure Monitoring (TPM)
sends warnings to the on -board
computer’s display screen in
the event of low t yre pressure as
well as in the event of a loss of
pressure. The system is available
as an option for the Panamera
and Panamera 4 and is standard
in all other models.
* Available from 10/2010 at the earliest.

Balance | Safet y
On request, we can equip any
Panamera model in the range with
a braking system that has already
had to cope with the harshest
requirements of the racetrack: the
Porsche Ceramic Composite Brake (PCCB). For the Panamera
and Panamera S models, it is
available only in conjunction with
19 -inch wheels or larger and for
the Panamera Turbo, it is com
-
patible only with 20 -inch wheels.
On the Panamera and
Panamera S models, the cross-
drilled ceramic brake discs have
a diameter of 390 mm at the
front and 350 mm at the rear. To
cope with more powerful brak -
ing on the Panamera Turbo,
these discs are 410 mm at the
front and 350 mm at the rear.
PCCB is characterised by its low
thermal expansion, which pre -
vents deformation under heav y
braking. Furthermore, the
ceramic brake discs are totally
resistant to corrosion and offer
more favourable noise- damping
properties. The use of six-piston aluminium
monobloc brake calipers on the
front axle and four-piston units at
the rear – all finished in yellow
– ensures extremely high brake
forces which, crucially, are excep
-
tionally consistent. The pedal
response is fast and precise with
only moderate input required.
All the necessary ingredients are
there for a short braking distance,
even in the toughest conditions.
Moreover, safet y under braking at
high speeds is increased thanks
to the excellent fade resistance of
PCCB.
The key advantage of PCCB is
the extremely low weight of the
ceramic brake discs, which are
approximately 50 % lighter than
standard discs of similar design
and size. As well as enhancing
performance and fuel economy, this represents a major reduction
in unsprung and rotating masses.
The consequence of this is bet ter
road holding and increased com
-
fort, particularly on uneven roads,
as well as greater agilit y and
improved handling. Please note that circuit racing,
track day use and other forms of
performance driving can signifi
-
cantly reduce the service life of
even the most durable brake pads
and discs.
As with conventional high-
performance braking systems,
we recommend that all brake
components be professionally
inspected and replaced where
necessary after every track
event.

Presumably, you won’t be using your Panamera for motorsport activities.
But you never know.

Personality | Comfort
In the new Panamera and
Panamera 4 models and in the
Panamera S and 4S, a total out -
put of 235 wat ts is produced
through a combination of 11 loud -
speakers. Fit ted as standard in
the Panamera Turbo, the BOSE
®
Surround Sound System (p. 114)
enables the playing of audio
sources in the Dolby Digital 5.1
format. For an even greater sound
experience, PCM can be combined
with the optional Burmester®
High - End Surround Sound System
(p. 116).
In conjunction with the PCM,
an optionally available universal
audio interface enables you to
connect an iPod® or any other
compatible MP3 player via the
USB port.* An AUX interface for
connecting other audio sources is
also provided. An optional hybrid
T V tuner is capable of receiving
free-to -air analogue and digital
broadcasts. PCM can also be
used to control the performance
display of the optional Sport
Chrono Package Plus (p. 74) or
Sport Chrono Package Turbo
(p. 76). A navigation module with high-
speed hard drive is included with
PCM. For route guidance, it is
possible to select bet ween a 2D
display and a new 3D perspec
-
tive. In some regions, it is even
possible for buildings and terrain
superimposed with a satellite
image overlay to be displayed in
3D. The remaining journey dis -
tance is automatically adapted to
the maximum screen size. Split -
screen mode enables you to view
t wo functions at once, such as
the current navigation map and
list of symbols representing your
next driving instructions.
Voice control system.
Do you require navigation assist -
ance, need to make a phone
call or simply want to listen to the
radio? Then why not just say so?
The optional voice control system
for PCM is at your command with
support for word-by-word input.
You can even browse through lists
by voice command.
Electronic logbook.
An electronic logbook is available
for PCM as an option. It enables
automatic logging on every journey
of mileage, route distance, date,
time, starting location and desti -
nation. The soft ware fulfils all
statutory requirements for auto -
matic logbooks as specified by
the German revenue authorities.
Telephone module.
Available as an option for the
Panamera and Panamera 4 (stand-
ard on Panamera S, Panamera 4S
and Panamera Turbo), the GSM
telephone module offers conven -
ience and excellent reception.
By inserting a SIM card directly
into PCM’s integral SIM card
reader, calls can be made using
either the hands-free facilit y or
the cordless handset. For even
more convenience, the Bluetooth®
capabilit y of a mobile phone can
be used to make calls through the
SIM Access Profile (SAP). Once
automatic pairing is complete, the
mobile phone’s aerial is switched
of f to conserve bat ter y charge
and the phone operates via the car aerial. Depending on the t ype
of mobile phone, this gives access
not only to the numbers on the
SIM card, but also to the phone’s
internal memory. Also, depending
on the phone, it can be controlled
using PCM, the multifunction
steering wheel or the voice con -
trol system, without it ever leaving
your pocket.
In addition, the telephone module
enables you to establish a
Bluetooth® link with those mobile
phones that only support the
Handsfree Profile (HFP). In this
case, the GSM connection is
always established through the
aerial of the mobile phone. PCM
acts as a hands-free system and
you can leave the mobile phone
tucked away. Please refer to the
note on page 159.
Stowed in the centre console, the
telephone module has a cordless
Bluetooth
® active handset with
display and keypad so that calls
can be made and received pri -
vately in the presence of other
passengers. However, the handset
cannot be used for Bluetooth
®
links established using the Hands -
free Profile (HFP).
