Spending time in the virtual world can be
great fun. The only thing is, you can’t feel
the wind against your skin as you acceler-
ate through every t wist and turn. The
Boxster celebrates real life. Whether it
is known as a design classic, a powerful
mid-engined sports car or a pure-bred
roadster, it does full justice to its famous
predecessors, such as the 356 No. 1 or
the 550 Spyder. We were faced with the question of how
it could do so in the future. As ever, the
answer was to be found in the harmoni
-
ous blending of st yle with functionalit y
and of tradition with innovation. But what
is harmony? Something quaint? Some -
thing soft and delicate? Not for us.
This is why we have refined our idea of
what a roadster should be and honed and
sharpened it to give it a completely new
expression.
For some things in life,
there will never be an app.
The Boxster concept.
We achieved this with Intelligent Perfor -
mance. With increased power output at
the same time as enhanced efficiency.
With innovative technologies and intelli -
gent lightweight construction. With a
sport y exterior and interior with aestheti-
cally appealing lines and curves in all the
right places.
The spirit of the pure-bred roadster is
very much alive and kicking. More inde -
pendent than ever before, it is even
more powerful, visceral and intense.

Design
Sometimes, spontaneity
takes years of work.
Design.Exterior.
We have redefined the Boxster in terms
of its performance, and defined how the
roadster of the future should look. In doing
so, we have once again succeeded in cre -
ating an icon of independence. Just like
its legendary predecessors, it is a Porsche
that continues to epitomise the feeling of
genuine freedom and advancement. The vertical contour of the headlights was
inherited from Porsche race cars of the
1960s and 1970s, but while the new

Boxster may be infused with the genes
of past generations, also it ushers in a
new and forward-looking design ethos.
It ushers in a new and forward-looking
design ethos. Large, imposing air intakes give the front

a powerful appearance.
The side contour promises thrilling perfor -
mance, while the long wheelbase and low,
raked windscreen are integral to forming
the stretched, wedge-shaped silhouette.
With the hood closed, this impression is
reinforced by the extremely sporting roofline. Large wheels, up to 20 inches in
size, make a st ylish addition to the clas
-
sic roadster. These emphasise the cars
wide track and help to achieve a com -
pletely new level of athletic performance.
The distinctive shoulder line gives further
emphasis to the wheels and, in combina -
tion with the side air intakes, to the mid-engine layout. Such features are

reminiscent of the 718 RS 60 Spyder,
a light weight mid-engined sports car

that achieved success in endurance racing
and hillclimbing championships alike.
Precise lines, which run elegantly across
the wings to the rear, make the new
Boxster unique among Porsche models. While its overall look is just as imposing,
its lines are more sharply defined than

on any Porsche we’ve seen before.

What use is expertise if it isn’t put into
practice and applied to the road?
In the Boxster, the 2.7-litre horizontally
opposed six cylinder engine delivers
195 kW (265 hp); in the Boxster S, the
3.4 - litre equivalent generates 232 kW
(315 hp). Both mid-mounted engines
feature direct fuel injection (DFI) and Vario -
Cam Plus for a significant increase in both
power output and efficiency. The SPORT
but ton on the centre console is fit ted
as standard and opens up even more agile
responses. Power is transmit ted to the
wheels by a light weight six-speed manual
gearbox or the optional 7-speed Porsche
Doppelkupplung (PDK).
A series of innovative technologies is key
to achieving exemplary efficiency. As
standard, these include the auto start/stop
function, electrical system recuperation,
energy-saving electromechanical power
steering, intelligent thermal management
and, in conjunction with PDK, the coast -
ing function. The result, The result is a
significant reduction in fuel consumption
and, therefore, a reduction in CO

sions of up to 16 % compared with the
previous model (depending on the equip -
ment variant).

optional Sport Chrono Package includes
dynamic gearbox mounts for the first
time. They contain a fluid with magnetic
properties, which enables them to adapt
instantly to driving conditions and counter -
act the effects of inertia. The results are
perceptibly more stable handling during
performance driving, as well as a higher
level of ride comfort. The brakes at the front axle have a
greater

Brake (PCCB) is available as
an option.
The hood on the new Boxster models
makes it easy to clear your head. Fully
electric, it opens and closes in around nine
seconds and is operable up to a speed of
approx. 30 mph (50 km/ h).
The intelligent lightweight construction,
which uses aluminium for substantial
parts of the bodyshell, doors and luggage
compartment lids, helps to achieve an
excellent power-to-weight ratio.

Engine
At Porsche, the mid-mounted boxer engine
is more than a tradition, it is a legend.
One of the most renowned examples of its
use was in the 550 Spyder. In conjunction
with an intelligent lightweight construction,
this arrangement delivered outstanding
agility and cornering dynamics and proved
to be a key factor in the countless victo -
ries achieved on some of the world’s
most famous racetracks. In the 1960s,
the 718 RS 60 Spyder contributed to the
triumphant success of the mid-engined
race car with wins in hillclimbing and
endurance events. The mid-mounted engine belongs at

Porsche and it belongs in the Boxster.
The advantages speak for themselves.
The concentration of mass close to the
centre of the vehicle and the low centre
of gravit y produce extraordinary agilit y
and cornering dynamics. At the same
time, weight is uniformly distributed
bet ween the front and rear axles and
handling characteristics are particularly
well balanced. The combined result
enables the driver fully enjoy every
corner and maintain excellent control
over the vehicle.
Always mid- engined.
Never middle ground.
Boxer engines.
For us, there are many reasons to remain
faithful to the mid-mounted engine con -
cept, to keep transferring performance
from the racetrack to the road and to
continue to combine tradition with innova -
tion. How do we do it? Through Intelligent
Performance, our commitment to high
power with comparatively low fuel
consumption and emission figures.
With this aim, we developed t wo compact
and light weight boxer engines that are
characterised by their ability to deliver
high levels of power and efficiency simul -
taneously. Both engines are equipped
For fuel consumption and CO
2 emissions please refer to page 127. with ef ficient technologies as standard,
including VarioCam Plus, direct fuel

injection (DFI), auto start/stop, electrical
system recuperation and enhanced
thermal management.
What else could we have given the
mid-mounted engine? An even more agile
response. One press of the SPORT
but ton on the centre console makes
engine performance even more dynamic
for driving pleasure at the limits of
performance. Let ’s take a look in more
detail.

VarioCam Plus.
VarioCam Plus is a two-in-one engine
concept for adjusting the intake
camshafts and switching the lift of
the intake valves. The system first dif ferentiates bet ween
driver inputs that typify normal, everyday
driving and those inputs that demand
maximum performance. The electronic
engine management system then

imperceptibly adapts valve operation
to the prevailing conditions. This results in instant acceleration and
extremely smooth running.
In short, VarioCam Plus provides

extraordinary power with comparatively
low fuel consumption.

Integrated dry-sump lubrication.
Integrated dr y-sump lubrication ensures
a reliable supply of oil even when a sport y
driving st yle is adopted and the vehicle is
experiencing powerful lateral acceleration.
It also has additional cooling functions. The oil tank is located in the engine, there
-
by eliminating the need for an external oil
tank which saves both space and weight.
To reduce power losses and increase
efficiency, an electronically controlled oil
pump supplies the lubricating points
inside the engine as and when required.
This results in optimum supply of oil,
lower fuel consumption and reduced
emissions.

Six-speed manual gearbox.
The new Boxster models are equipped
as standard with a light weight six-speed
manual gearbox. Gearshifts are smooth
and optimally adapted to the respective
engine map. Shift throws are short and
sport y and the gear lever is easy to oper -
ate, enabling a rapid gearshift action and
providing a truly engaging driving experi -
ence. The upshift indicator located in the
central circular instrument helps you to
maximise fuel efficiency.
The elevated centre console gives you an
authentic sports car feel. It positions the
gear lever close to the steering wheel, which enables you to change gear as fast
and as ergonomically as possible.
Porsche Doppelkupplung (PDK).
Available as an option for the new Boxster
models is a completely retuned 7-speed
Porsche Doppelkupplung (PDK), featuring
both manual and automatic modes. PDK
offers extremely fast gear changes with no
interruption in the flow of power, improved
acceleration over the manual gearbox, very
short response times, reduced fuel con
-
sumption and a distinct increase in comfort.
In total, PDK has seven forward gears at its
disposal. Gears 1 to 6 have a sports ratio

Transmission.
and top speed is reached in 6th gear. The
7th gear ratio is longer and keeps engine
speed low to improve ride comfort and
reduce fuel consumption at higher speeds.
The design of PDK is similar to t wo
conventional gearboxes in one. The odd
numbered gears are housed on one
assembly and the even numbered gears
on another, each having its own clutch.
While one gear is engaged, PDK pre-
selects the next gear based on driver
input. When the next gear is requested,
drive is switched from one clutch to
the other in milliseconds, delivering gear
changes with no loss of drive.

Even when you want to make a break
from everyday life, you should still keep
your feet on the ground.
The chassis of the new Boxster models
are an excellent match for the powerful
engines. Axle components are made
predominantly of aluminium. This light -
weight material helps to keep the weight
of the vehicle and its unsprung masses
low, which reduces fuel consumption,
improves comfort and increases agility.
The wide track is a prominent feature to
provide additional stability and enhanced
comfort, the wheelbase has been extended
by 60 mm compared with that of the
previous model. The new independent
suspension features lightweight spring-strut
a
xles with longitudinal and transverse links
and, at the front, cross members that
have been refined for optimum control.
As a result, each wheel moves precisely
to ensure excellent directional stability
and superior handling in all situations.
What does this mean for the driver? The
sophisticated engineering of the chassis,
combined with the mid-engined layout,
achieves impressive dynamic performance.
Body roll and pitch have been practically
eliminated to offer a level of agilit y that
turns each corner into an incomparable
experience.
A love of freedom is no reason
to lose self-control.

actively and continuously 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. Depending on the mode selected,

therefore, PASM can be both sportier
and more comfortable than the standard
chassis. 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 record the body movements that
accompany powerful acceleration, brak -
ing or uneven road surfaces. This enables
intelligent adaptation of damper stif fness
for the selected mode, optimising contact
bet ween each individual t yre and the road
and reducing pitch.

Wheels.
The standard wheels on the new Boxster
models have been enlarged by one inch
compared with those of the previous
models. Made from a light weight alloy, the
larger wheels reinforce the car’s imposing
presence and further improve sport y
performance. The new Boxster is equipped with 18-inch
wheels. Their minimalist five-spoke design
is sport y and elegant in equal measure.
Tyre sizes are 235/45 ZR 18 and 265/45
ZR 18 at the front and rear respectively.
The Boxster S has 19-inch wheels with
a dynamic dual-spoke design. The t yre
size at the front is 235/40 ZR 19 and
265/40 ZR 19 at the rear.
The larger rolling circumference improves
comfort and performance. At the same time, the rolling resistance of the new gen
-
eration of t yres has been reduced which,
in turn, helps to reduce fuel consumption.
Wheels up to 20 inches are available as an
option.
Tyre Pressure Monitoring (TPM).
Optional Tyre Pressure Monitoring (TPM)
sends warnings to the on-board comput -
er’s display screen in the event of low t yre
pressure. The 4.6-inch TFT screen in the
instrument cluster enables the driver to
check the pressure in all four t yres. The system updates quickly and accurately

Brakes.
Porsche brakes set standards worldwide
for stopping power and stability. For
the new Boxster models, braking per for -
mance is as essential as driving perfor -
mance.
Both models are equipped with four-
piston aluminium monobloc fixed calipers
at the front and rear. This design means
that, not only are the brakes extremely
resistant to deformation, they are light -
weight for a particularly fast and sensitive
braking response.
The new generation of brake caliper at
the front axle, combined with enlarged
brake pads and the newly developed
brake booster, has managed to improve braking and component stability even
during continuous use. These two charac
-
teristics have also been optimised by the
newly developed brake ventilation system
with a modified air spoiler at the front
and rear axles.
The enhanced dynamics of the Boxster
and Boxster S also demand appropriate
brake discs. All Boxster brake discs are
internally vented and cross-drilled for
improved braking in wet conditions. On
the Boxster S, the diameter of the front
brake discs has been enlarged by 15 mm
to 330 mm. At the rear, the diameter is
the same as on the Boxster – 299 mm
The brake calipers on the Boxster and
Boxster S are black and red respectively.
Porsche Ceramic Composite Brake
(PCCB).
From the start, Porsche has been synon -
ymous with motorsport. Ever since
1948, when we found our identit y on the
racetrack, we have taken the experience
we have gained and applied it to the
road. The optional Porsche Ceramic
Composite Brake (PCCB) is a fine exam -
ple. This brake system has already had
to cope with the harshest requirements
of motor racing and is fit ted in cars
that compete in demanding events such
as the Porsche Mobil 1 Supercup.
The cross-drilled PCCB ceramic brake
discs for the new Boxster have a diame -
ter of 350 mm front and rear for even
more formidable braking performance. The use of six-piston aluminium mono
-
bloc fixed 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
exceptionally consistent.
PCCB enables shorter braking distances
in even the toughest road and race
conditions. Excellent fade resistance
ensures greater balance when slowing
from racetrack speeds.

Chassis
Another 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
comfort, particularly on uneven roads,
as well as greater agilit y and improved
handling. Please note that circuit racing, trackday
use and other forms of performance

driving can significantly reduce the
service life of even the most durable
pads and discs. As with conventional
high-performance braking systems, we recommend that all brake compo
-
nents be professionally inspected and
replaced where necessary after every
track event.
Electric parking brake.
The electric parking brake, which can
be activated and deactivated manually,
is released automatically as you pull
away with your seat belt fastened. A hill
hold function is integrated as standard for the manual gearbox and for PDK.
It assists you in making a comfortable,
smooth and roll-free start on an incline.
Whenever you come to halt on an incline,
this is detected automatically and the
braking effect of the electric parking brake is supplemented by application

of the wheel brakes. As long as a gear
remains engaged, the brake pressure
is maintained at all four wheels. To pull
away, simply apply throttle (manual gearbox: apply throt tle and release the
clutch pedal). The wheel brakes are
released as soon as sufficient starting
torque is available and the parking brake
is released as the vehicle moves off.
