2010 PORSCHE BOXSTER S steering

· 22 ·· 23 ·
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
Like a shot of adrenalin.
Intravenously.
The Boxster S.
(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.

Exhaust system.
The exhaust system – with t win
tailpipes on the Boxster S – is
made of stainless steel. Until it
converges in the connecting tube,
the exhaust gas is channelled
through t wo separate tracts and,
thanks to separate exhaust gas cleaning systems, the exhaust
gas can flow more freely – for
increased power and torque.
The stereo lambda control

circuitry controls and monitors
each cylinder bank separately.
For each exhaust tract, four
corresponding oxygen sensors regulate the composition of the
exhaust gas and monitor the con
-
version of pollutants in the cata -
ly tic converters.
A sports exhaust system – for a
more resonant sound – is avail -
able as an option for each of the
Boxster models.

Servicing.
Every Porsche is designed with
durabilit y in mind. On the Boxster
models, this is reflected in the
lengthy service intervals. The alternator, power steering
pump and the air- conditioning
compressor are all driven by a
single self-adjusting belt. The
drive chains on the camshafts
and intermediate shaf ts do not
normally require servicing. With the sole exception of the
spark plugs, the ignition system
is also maintenance-free.
So your Boxster remains where
it belongs for as long as possible:
on the road.

Three-spoke sports steering
wheel with gearshift switches.
In conjunction with the optional
Porsche Doppelkupplung (PDK),
the standard three-spoke sports
steering wheel features t wo
ergonomic switches. One press
with the thumb and the PDK
shif ts up. One pull with the index
finger and the PDK shif ts down.
Either the right or left hand can
be used.
When combined with the optional
Sport Chrono Packages (p. 56),
an additional display is located
above the airbag module telling you whether the SPORT, SPORT
PLUS and Launch Control func
-
tions are activated.

paddles are made from a strong
alloy and are ergonomically
located behind the steering wheel
spokes. Pull the right-hand paddle
and the PDK shif ts up. Pull the
left-hand paddle and the PDK
shifts down.
Visually, the steering wheel is
distinguished by its distinctive,
high - qualit y t win -spoke design
and silver-coloured galvanised
spoke cover. The airbag module
is finished in the same colour
as the steering wheel rim.
Displays in the left and right-
hand steering wheel spokes tell
you whether the SPORT, SPORT
PLUS and Launch Control func -
tions are activated. Another

feature reminiscent of the world
of motorsport is the top centre
marking on the steering wheel
rim.

Gear selector for PDK.
The gear selector for PDK im-
presses not only with its unique
design, but above all with its
superior functionality enabling
you to change gear manually.

Press forwards to shift up, pull
backwards to shift down. Even if
the gear selector is set to auto -
matic mode, you can still change
gear manually using the switches
on the steering wheel.
Six-speed manual gearbox.
Fit ted as standard is a six-speed
manual gearbox which is per -
fectly matched to the character -
istics of the engine. The shif t
throw is short and precise, the
tuning is sport y – as befits the
character of the Boxster models.
The dual-mass fly wheel mini -
mises engine noise and the con -
trol cable mechanism prevents
vibrations from being transmit ted
to the gear lever.

making a comfortable, smooth
and roll-free start on an incline.
The system detects you have
braked to a halt on an incline.

Provided a gear is engaged, the
brake pressure is maintained
approximately t wo seconds once
the footbrake is released. The
vehicle is therefore temporarily
prevented from rolling backwards.
Brake pressure is reduced if
sufficient revs have been gener -
ated depressing the accelerator
pedal (for manual transmission,
the accelerator pedal is de-
pressed and the clutch engaged).

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.

Sport Chrono Package.
The Boxster combines open -top
driving with performance which
at Porsche has its origins on the
racetrack.
As an option, for both models we
offer the Sport Chrono Package
which enables even sportier tuning
of the chassis and engine and
guarantees even more driving
pleasure.
Selecting the SPORT but ton

on the centre console activates
‘Sport ’ mode, which makes
throt tle the response significantly
more immediate, adjusts the
rev-limiter to a harder set ting,
and tunes the engine dynamics
for performance driving.
The optional Porsche Active

Suspension Management (PASM)
also switches to ‘Sport ’ mode,
which of fers harder damping and
more direct steering and, there-
fore, bet ter road holding.

With the optional PDK in auto -
matic mode, gearshif t points are
delayed until the upper rev range.
The shif t times are shorter, the
gear changes sportier. At low rates
of deceleration, the system
initiates a swif ter, brake-induced
downshift. In manual mode, gear
changes are faster and more
dynamic.
In ‘Sport ’ mode, the PSM (p. 63)
intervenes later for increased
longitudinal and lateral dynamics.
PSM now affords greater
manoeuvrabilit y under braking
and exit acceleration, especially
at low speeds.
For maximum dexterit y, PSM can
be set to standby while the car is
still in ‘Sport ’ mode (p. 63). For
safet y, it is set to intervene auto -
matically only when ABS assist -
ance is required on both the front
wheels.
A key component of the Sport
Chrono Package is the swivel-
mounted in the centre of the
dashboard with analogue and
digital display.
In combination with the optional
Porsche Doppelkupplung (PDK),
the Sport Chrono Package of fers
t wo additional functions that
are activated by the SPORT PLUS
but ton.
First, ‘Launch Control’, which
ensures you achieve the fastest
possible rate of acceleration
from a standing start – on the
race track, for example. ‘Launch
Control’ is operated via the
SPORT PLUS but ton with the ‘D’
or ‘M’ drive position selected.
Whilst the driver depresses the
brake pedal with the left foot,
the right foot depresses the
accelerator pedal to the floor.
With the accelerator in the kick -
down position, the system
detects the driver’s request for
Launch Mode and revs the
engine to an optimum speed of
approximately 6,500 rpm.
Boxster | Chassis
Engine torque increases and the
clutch closes slightly. The mes -
sage ‘Launch Control ’ appears
in the display on the PDK steer -
ing wheel. The driver now quickly
releases the brake – and pre -
pares for maximum acceleration.

Second, the ‘motorsport- derived
gearshif t strategy’. Using this,
PDK is geared up for maximum
shif t speed, the shortest possible
shif t times and optimum shif t
points for maximum acceleration
– ideal for the racetrack.
Sport Chrono Package Plus.
On request, the optional Porsche
Communication Management
(PCM, p. 83) can be combined
with the Sport Chrono Package
Plus. In addition to the functions
of the Sport Chrono Package,
it includes a personal memory
function in the PCM and a per-
formance display for evaluating
lap times.

Active safety.
Uncompromising sports per-
formance. Comprehensive safet y.
At Porsche, these qualities have

always been inextricably linked.
Just as in the Boxster models
where the body, chassis and
brakes constitute a single inte -
grated system with generous
safety reserves.
The chassis setup allows for an
extremely sport y driving st yle
with exceptional cornering control.
The variable ratio steering is
direct and precise with excellent
feedback from the road.

The braking system ensures
maximum deceleration and

stabilit y. A high power-to -weight
ratio and responsive throt tle
enable easier overtaking and
evasive manoeuvres. Porsche
Stabilit y Management (PSM,

p. 63) fit ted as standard helps
to stabilise the vehicle in critical
driving scenarios, even in
unfavourable weather conditions.
Also contributing to active
safet y is the ef fective headlight
concept which guarantees
excellent vision at night (p. 64).
Boxster | Safet y
Braking system.
The Boxster and Boxster S have
a braking system with four-
piston aluminium monobloc brake
calipers fit ted front and rear.
Offering excellent rigidit y, they
are compact and save on weight.
Their superior responsiveness,
for fast and sensitive braking, sets
them apart.
A brake booster reduces pedal
ef fort whilst maintaining powerful
braking. A special ventilation
system, whereby the entire wheel
brake is cooled through openings
in the front end and special
channelling systems, increases
the stabilit y of the brakes during
heav y use.

Both the Boxster and Boxster S
have internally vented brake
discs at the front with a diameter
of 318 mm, whilst the rear discs
measure 299 mm. The result is
impressive braking performance.
The brake discs on the Boxster S
are 4 mm thicker than those
on the Boxster, which increases
stabilit y even further. To distinguish them visually,

the brake calipers on the Boxster
have a black anodised finish
while those on the Boxster S are
painted red.
For reduced weight, bet ter cool -
ing and optimum braking in the
wet, the brake discs are cross-
drilled.

For an even sportier drive, PSM
can be deactivated. However,
it is automatically reactivated for
your safet y if either of the front
wheels (in ‘Sport ’ mode, both of
the front wheels) requires ABS
assistance. ABD remains perma -
nently active.
PSM includes t wo additional func -
tions: precharging of the brake
system, and brake assist. If you
suddenly release the accelerator
pedal, PSM automatically readies
the braking system. With the
braking system having been
precharged, the brake pads are
already in light contact with the
brake discs. Maximum braking
power is therefore achieved
much sooner. When sudden brak -
ing is detected, the brake assist
function applies maximum brake
pressure to all four wheels.
Lights.
The Boxster models are all fit ted
with halogen headlights with
LED position lights integrated
separately into the front light unit
with integral fog lights above the
outer air intakes.
LED technology is also used in
the taillight unit to provide bet ter
illumination and respond more
quickly to driver input. Further
benefits are that LED bulbs are
energy saving and have a longer
life than conventional bulbs.

The design is unmistakable, both
day and night.
Bi-Xenon headlights with
dynamic cornering lights and
LED daytime running lights.
Available as an option for both
Boxster models are Bi-Xenon
headlights which include dynamic
cornering lights and LED day time
running lights.
Bi-Xenon headlights are brighter
than halogen headlights so that
they of fer improved visibilit y and
they illuminate the road more evenly. In fact, they are so effec
-
tive that separate fog lights are
no longer necessary. A headlight
cleaning system is built-in.
Dynamic cornering lights of fer
particularly effective illumination
of the road ahead, especially
through bends. Sensors continu -
ously monitor the speed, lateral
acceleration and steering lock
and, from these variables, calcu -
late the course of the bend.
This determines the angle
of the dynamic cornering lights,
with the lights able to swivel
into the corners up to a limit of
15 degrees, even with main
beam switched on.

What leads us to make a thorough-
bred roadster as comfortable as
possible? Your desire to drive it
every day, in every situation, and
in every season. So the entire
concept of the Boxster is based on intelligent function. And that ’s
evident from the interior too.
All controls are designed and
oriented around the most

important element: the driver.
At Porsche, form follows function
– and the driver.
The front centre console includes
the CDR-30 audio system with
single CD drive as standard. Or
alternatively, the optional Porsche
Communication Management
(PCM, p. 83). The climate controls,
switch panel and a storage
compartment are also integrated
into the new centre console.
The seats offer excellent support,
even during high-speed corner -
ing, and have a wide adjustment
range. The roomy interior means
that even taller drivers can
find their ideal seating position.

The steering wheel with height
and reach adjustments, and the
position of the pedals contribute
to the comfortable drive.
All materials are carefully selected
for their visual and tactile
qualities and create an unique
atmo sphere. Even when your
entire concentration is on the road.
