Boxster S
Boxster in Porsche Racing Green Metallic
An extraordinarily powerful mid-
mounted engine. An extremely
low centre of gravit y. Very high
agilit y and dynamic handling.

The driving experience offered
by a Boxster goes far beyond
superficial driving pleasure. That ’s
because it ’s based on a concept
which made the 550 Spyder one
of the most successful racing
cars of its time. We see it as the
very embodiment of Porsche
Intelligent Performance.
Both models are powered by
sophis ticated engines. The

Boxster’s six- cylinder Boxer engine,
fit ted with VarioCam Plus (p. 36),
has a 2.9 -litre capacit y, 188 kW
(255 hp) and maximum torque of
290 Nm at 4,400 to 6,000 rpm.
Taking it to 100 km/ h (62 mph)
in just 5.9 seconds, with a top
speed of 263 km/ h (163 mph). Despite this increase in power,
the CO
2 emissions have been
reduced by up to 12
% compared
with the previous model. In com -
bination with the optional Porsche
Doppel kupplung (PDK), the
result is a very low emissions
value of 214 g / km and fuel
consumption of 9.1 l/100 km
(31 m pg ).
The Boxster S has an additional
power boost, with direct fuel injec -
tion (DFI, p. 28) fit ted as standard.
This provides optimum fuel mix-
ture formation for improved fuel
ef ficiency and a distinct increase
in power and torque. In combi-
nation with the optional PDK, this
gives a reduction in fuel con-
sumption of 15 % and lowers CO2
emissions by 16 % compared with
the previous model.
The pleasure of a roadster.
The excitement of a Porsche.
The Boxster models.
The 3.4-litre six- cylinder Boxer
engine in the Boxster S develops
an impressive 228 kW (310 hp).
Maximum torque of 360 Nm is
reached bet ween 4,400 and
5,500 rpm and acceleration to
100 km/ h (62 mph) takes just
5.3 seconds.

In summary, an engine which
is responsive enough to provide
power from the outset – and
reaches its limit at 274 km/ h
(170 mph).

In both models, a precision six-
speed manual gearbox makes
optimum use of the power and
torque of the engine. Available
as an option is Porsche Doppel-
kupplung (PDK, p. 42) featuring
both manual and automatic
modes.
The principle is as impressive
as it is simple: it has seven
gears, t wo half gearboxes and
t wo clutches. As one gear is
engaged, the next is already
preselected in the other half
gearbox.
Gear changes take place in milli
-
seconds without any interruption
in the flow of power. The advan -
tage over a fully manual trans
mis -
sion is the considerably faster

rate of acceleration for the same
level of fuel consumption. The
advantage over a fully automatic
transmission is a perceptible
increase in driving dynamics –
with a similar level of comfort
and a distinct reduction in fuel
consumption. In short, Porsche
Doppelkupplung (PDK) not only increases the agilit y of the

Boxster but also enhances
driving pleasure.
As you would expect, the chas-
sis setup ensures a supremely
sport y ride. A wider track and
generously dimensioned wheels
in a dynamic design provide an
even sportier driving experience.
The optional mechanically locking
rear dif ferential (p. 54) delivers
high traction and increased per -
formance.
When fit ted in combination with
PDK, the optional Sport Chrono
Package (p. 56) gives you access

to t wo further functions: ‘Launch
Control’ for maximum accelera -
tion from a standing start, and
a ‘motorsport-derived gearshift
strategy’, bringing gearshift
characteristics straight from the
racetrack.

The standard Porsche Stabilit y
Management (PSM, p. 63) further
enhances active safet y with its
brake assist feature and a pre-
charging function which increases
braking system readiness.

The design of the Boxster models
is governed by one philosophy
above all: that the st yling of a

Porsche reflects its inner values.
Here, the primary value is extreme
performance.
In the interior, the elegant sports
st yling is coupled with a high
degree of practicalit y. All the
important functions are intuitive
to control, including the optional
Porsche Communication Manage -
ment (PCM, p. 83) with 6.5-inch
touchscreen and CD/ DVD drive
with navigation module.
In conjunction with the PCM, the
optional BOSE
® Surround Sound
System supports 5.1 surround
sound.

A rhetorical question: What would
you do if we were to give you
the key now?
A real roadster is like true love:

Design.
This concept also follows a
traditional Porsche theme: the
seamless blend of function
and design. Visually exciting
with performance to match.
The emphasis on high perform -
ance is immediately evident
from the front, where large air
intakes in a powerful geometric
design lend both Boxster models
a dynamic look – and increase
cooling power. On the Boxster,
the air intake grilles are finished
in the exterior colour, whereas
on the Boxster S they are con-
trasted in sporting black. The
athletic
appearance is comple -
mented by
striking spoiler lips.
The t wo models have a drag
coefficient
value of 0.29 and
0.30, respectively.
At the front, the headlight design
makes the Boxster models unmis
-
takable – especially at night.
The Boxster models are fit ted as
standard with halogen headlights
and LED day time running lights
integrated separately into the clus-
ters above the outer air intakes.
Bi-Xenon headlights with dynamic
cornering lights, including LED
day time running lights, are avail -
able on request. The dynamic
headlight design emphasises the
striking contour of the wing.

The rear features LED taillight
modules that blend harmoniously
with the overall design. The
centrally located stainless steel
tailpipe – t win tailpipes on the
Boxster S – and the rear diffusers
finished in sporting black com -
plete the powerful look. The
dynamic presence of the Boxster
models is further emphasised
by the clean, neat design of the
wheels. The Boxster is fit ted with
17-inch wheels as standard, the
Boxster S with 18-inch wheels.
A 19-inch option is available for
both models.
In short, although we rarely stick
to the rules, we have observed
one: form follows function. Design
and functionalit y are combined
perfectly in the Boxster models.

Boxster
Boxster
You can tell a good concept from
t he fact t hat i t isn’t just short- term.
We appear to have got something
right.
Because the basic concept
of the Boxster has lost none of its
appeal in over 60 years. Even though the gap bet ween the
Porsche 356 No.1, the 550 Spyder
and the Boxster seems huge, it ’s
still an out-and-out roadster. High

performance, lightweight con
-
struction, sporting agility, pure
driving pleasure – these values
are reflected in every detail.
Many fairytales begin with ‘Once upon a time’.
But only a few true stories do.
The Boxster.
The 2.9-litre six-cylinder Boxer
engine delivers a power output
of 188 kW (255 hp) at 6,400 rpm
and a maximum torque of 290 Nm
at bet ween 4,400 and 6,000 rpm.
The six-speed manual gearbox
has been optimally matched to
the engine characteristics
and high power output. From a
standing start, the Boxster accel-
erates to 100 km/ h (62 mph) in
5.9 seconds. Or just 5.8 seconds
with the optional Porsche Doppel -
kupplung (PDK, p. 42). And com -
plementing this perfectly is the
sporty, lightweight chassis.
Integrated centrally below the
rear panel is a stainless steel tail -
pipe which produces the distinc -
tive Boxster sound.
The 17-inch Boxster III wheels
with an open five-spoke design
allow a clear view of the brake
system with its black anodised
four-piston aluminium monobloc
fixed calipers. The large front
and rear brake discs ensure excel -
lent braking performance.

Adding further to the st ylish
design of the Boxster are the
front air intake grilles finished
in the exterior colour.
The Boxster. A roadster that
stirs emotions. Because it
doesn’t just reflect the passion
of our engineers, but over half
a century of Porsche history.

The flagship model in the Boxster
range has also evolved: the
Boxster S. It presents an even
more athletic interpretation
of the roadster concept. More
powerful and more ef ficient. Its
engine is fit ted with direct fuel
injection (DFI, p. 28) as standard. For increased torque and power
– with a simultaneous reduction
in fuel consumption. The result is
228 kW (310 hp) at 6,400 rpm
and a maximum torque of 360 Nm
at 4,400 –5,500 rpm. It acceler -
ates from 0 to 100 km/ h (62 mph)
in just 5.3 seconds. With the
optional Porsche Doppelkupplung

(PDK, p. 42) and ‘Launch Control’
from the optional Sport Chrono
Package, just 5 seconds. Com-
pared with the previous model,
fuel consumption has been
reduced by up to 15 % depending
on the t ype of gearbox fit ted,
and CO2 emissions by up to 16 %.

As well as the 18-inch Boxster S II
wheels in a dynamic design, the
Boxster S is fit ted with a power -
ful braking system which is
distinguished by its red-painted
calipers. The rear brake discs
are thicker than those on the
Boxster for increased stabilit y
under braking. The front air intake grilles are
painted black for a striking con
-
trast. Together with the centrally
mounted t win tailpipe, they give
the car a powerful presence.

In the interior, as well as leather
on the steering wheel, PDK selec -
tor/gear lever, handbrake lever
and door handle, the Boxster S
has leather trim on the storage
compartment covers in the door
and the rear centre console. The
instrument dials are aluminium -
coloured.

These are just the facts. To expe
-
rience the performance of the
Boxster S, we can only of fer one
piece of advice: you really need
to drive it.

The optional Porsche Doppel-
kupplung (PDK), with both man -
ual gearshift and an automatic
mode, enables smooth gear
changes with no interruption in
the flow of power. This results

in significantly faster acceleration
and lower fuel consumption, without having to sacrifice the
ease of automatic transmission.
In total, PDK has seven gears at
its disposal. Gears 1 to 6 have a
sports ratio and top speed is
reached in 6th gear. The 7th gear
has a long ratio and helps to

reduce fuel consumption even
f u rt h e r.
PDK is essentially t wo half gear-
boxes in one and thus requires
t wo clutches – designed as a
double wet clutch transmission.
This double clutch provides an
alternating, non-positive connec -
tion bet ween the t wo half gear -
boxes and the engine by means
of t wo separate input shafts
(input shaft 1 is nested inside the
hollowed-out input shaft 2).
The flow of power from the
engine is only ever transmit ted
through one half gearbox and
one clutch at a time, while the
next gear is preselected in the second half gearbox. During a
gear change, therefore, a con
-
ventional shif t no longer takes
place. Instead, one clutch simply
opens and the other closes at
the same time. Gear changes
can therefore take place within
milliseconds.
Clutch 1 controls the first half
gearbox, which contains the odd
gears (1, 3, 5, 7) and reverse.
Clutch 2 controls the second,

which contains the even gears
(2, 4, 6).

The crankshaf t transmits engine
torque to the dual-mass fly wheel

the clutch housing and onto the
multi-plate clutches, or to be more
precise, the outer disc carrier.

Under oil pressure, clutch 1
closes and forms a frictional
connection with input shaf t 1.
The torque is now transmit ted
through the first half gearbox
– and then the dif ferential – to
the rear axle. At this stage,
PDK has already preselected
the next gear in the second
half gearbox. Engine torque
is already acting on the other
outer disc carrier and, in
response to a gear change
signal, the overlap shift is initi -
ated, i.e. as clutch 1 opens,

clutch 2 closes. The non-positive
connection with input shaft 2
is
established, and power is
trans
mit ted to the wheels.
The gear which is engaged is
displayed on the instrument
cluster.
Depending on the gearshift
programme, the gear change
is optimised for comfort or for
sport y handling and takes place
in a mat ter of milliseconds.

The advantage over a fully manual
transmission is the considerably
faster rate of acceleration for the
same rate of fuel consumption.
Boxster | Drive
The advantage over a fully auto -
matic transmission
is the per -
ceptible increase in driving
dynamics – with a similar level of
comfort, and a distinct reduction
in fuel consumption.
The com -
pact dimensions of the gearbox
reduce rotational
masses which
means a more direct engine
response, and the system is
more lightweight.

This, along with the long-ratio
7th gear, helps to achieve
reduced fuel consumption and
emission figures comparable with
those of a manual gearbox.
With the optional Sport Chrono
Package, PDK is enhanced by
the
‘Launch Control’ and ‘motor-
sport- derived gearshif t strategy’
functions (p. 57). In essence, PDK combines sport
i
-
ness with efficiency and comfort.

Boxster and Boxster S
Suspension.
The suspension of the Boxster
models has been tuned to match
the high performance of the
engines.
Light weight coil- over McPherson
struts are combined with lateral
control arms to ensure excellent
driving dynamics and safet y on
all road surfaces. The axle kine-matics are designed for high
performance, as is the generous
wheel track. Light weight con
-
struction throughout keeps the
overall weight and unsprung
masses low, with almost all mov -
ing parts made from aluminium.
The mid-engine design, in com -
bination with the complex chassis
technology, results in minimum
roll and pitch movements on
cornering, braking and accel -
eration.
The chassis of the Boxster
models ensures high safet y
reserves irrespective of load,
and easily controllable load
transfer when cornering. Corner -
ing stabilit y is exemplary, even
in high-speed bends. The same
applies to straight-line stabilit y.
Steering.
What use is a perfect suspension
setup without perfectly tuned
steering? For Porsche, this would
be inconceivable. The solution
is a steering system which is as
precise and immediate as the
chassis itself and, thanks to the
power assistance, steering ef fort
is reduced to a comfortable
level. Around the straight-ahead
position, such as during motor -
way driving, the ratio is less
direct but with no loss of agilit y
or feedback.
Boxster | Chassis
The greater the steering angle,
the more direct the steering
ratio. This is particularly notice-
able when turning tight corners
or parking. The car has a turning
circle of just 11.1 m.

Wheels.
A range of sophisticated wheels
ensures both models deliver
exceptional driving performance,
without compromising on ride
comfort. The Boxster is fit ted with
17-inch wheels in an open five-
spoke design, and the Boxster S
has 18-inch wheels with a
dynamic sport y look. Wheels up
to 19 inches are available for both
models on request. All available
wheels are equipped with anti-
theft protection. A selection of
alternative wheels is featured
on page 108.
Specifically for the cold season,
winter t yres and snow chains
are available from the Porsche
Tequipment accessory range.
Tyre Pressure Monitoring
(TPM).
The optional Tyre Pressure Moni -
toring (TPM) sends warnings to
the on -board computer’s display
screen in the event of low t yre
pressure.

The driver can check the pres -
sure in all four t yres via the instrument cluster. The system
updates quickly and reliably

each time the engine is started, whenever the t yre pressures
are corrected or a wheel is
changed – ensuring a high degree
of comfort and safet y.

Porsche Active Suspension
Management (PASM).
The optional PASM is an elec -
tronic damping control system.
On the Boxster models, the
suspension has been tuned to
match the high power of the
engine. PASM actively and con -
tinuously regulates the damping
force for each wheel according
to the road conditions and driving

st yle. In addition, the suspension
is lowered by 10 mm.
The driver can select bet ween
t wo dif ferent modes: ‘Normal’
which is a blend of performance
and comfort, and ‘Sport ’ where
the setup is much firmer. The
PASM control unit evaluates the
driving conditions and modifies
the damping force on each of
the wheels in accordance with
the selected mode.
Sensors monitor the movement
of the vehicle body, for example,
under heav y acceleration and
braking or on uneven roads. The
control unit tunes the dampers

to the optimum hardness for the
selected mode to reduce roll and
pitch still further and to increase
contact bet ween each individual
wheel and the road.
In ‘Sport ’ mode, the suspension
is set to a harder damper rating.
On uneven roads, PASM imme-
diately switches to a softer
rating within the ‘Sport ’ setup
range, thereby improving con-
tact bet ween the wheels and the
road. When the road surface
improves, PASM automatically
reverts to the original, harder
rating.
If ‘Normal’ mode is selected and
the driver’s st yle becomes more
assertive, PASM automatically
switches to a harder rating within
the ‘Normal’ setup range.
Damping becomes harder, and
driving stabilit y and road safet y
are increased.
Mechanically locking rear
differential.
Are you a fan of sport y driving?
In your spare time, do you
enjoy the occasional outing on
the racetrack? Then you
shouldn’t do without the optional
mechanically locking rear differ -
ential available in conjunction
with 18-inch or 19-inch wheels.
It further enhances the traction
of the driven rear wheels on
uneven roads and when acceler -
ating out of tight bends. Road
holding at the limits of perform -
ance is even more impressive.
The car holds its course bet ter
and so PSM intervenes less often.
In other words, sheer driving
pleasure and faster lap times.
