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

the selected mode. Dynamic per formance
can be further improved with optional
Porsche Torque Vectoring (PTV). The
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
surface area for improved braking perfor -
mance. The Porsche Ceramic Composite
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.

Thermal management.
The Boxster models feature a new version
of thermal management to reduce friction
losses that arise during the warm-up
phase.
Thanks to the selective control strategy
and on-demand, gradual activation of the
various cooling circuits, the engine and
gearbox warm up to normal operating
temperature more rapidly. The conse -
quent reduction in friction also reduces
fuel consumption and CO
2 em issio ns.
During sporty driving, thermal manage -
ment also acts to reduce temperatures
so that a high level of performance is
maintained. Our cross-flow cooling system, as used

in motorsport, supplies each engine
cylinder uniformly with coolant, which
protects the valves against thermal
overload and, therefore, premature wear.
This improves combustion and keeps
emissions, fuel consumption and noise
comparatively low.
Exhaust system.
In the new Boxster models, each cylinder
bank has its own stainless-steel exhaust
tract. Downstream of their respective
rear silencer, the tracts converge into
a connecting tube and a single (Boxster)
or t win (Boxster S) tailpipe. The stereo
Lambda control circuitr y controls and monitors each cylinder bank separately.
For each exhaust tract, four correspond
-
ing oxygen sensors regulate the composi -
tion of the exhaust gas and monitor the
performance of the catalytic converters.
Having separate tracts means that the
exhaust gas can flow more freely. The
resulting reduction in pressure loss has a
positive impact on power output, torque
and the unmistakable engine sound.
Available as an option for the new Boxster
models is the sports exhaust system
1)
including sports tailpipe. It produces an
even more resonant Porsche sound.

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

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.

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.

Sport Chrono Package.
Time is precious and every hundredth
of a second counts. The optional Sport
Chrono Package makes your driving experi -
ence priceless thanks to an even sportier
tuning of throt tle response and handling
characteristics.
The package comprises dynamic gear-
box mounts, a per formance display,
a digital and analogue stopwatch and
the SPORT PLUS but ton. When this
is pressed, optional Porsche Active
Suspension Management (PASM) switches
to ‘Sport ’ mode for harder damping
and more direct steering and therefore,
even more intensive road holding.
The trigger threshold for PSM is raised.
Agilit y is perceptibly enhanced when
braking for corners with PSM, allowing
even sportier braking and exit acceleration.
For even greater dexterit y, PSM can be set to standby while the car is still in
SPORT PLUS mode. For safet y, it is set
to intervene automatically only when ABS
assistance is required.
In conjunction with optional PDK, the Sport
Chrono Package comes with t wo additional
functions for a sport y drive that borders
on a motorsport experience. The first
is ‘Launch Control’, which is designed to
produce a racing start.
The second function is the involving

‘motorsport- derived gearshif t strategy’.
Using this, Porsche Doppelkupplung (PDK)

is geared up for the shortest possible
shift times and optimum shift points,
while torque boosts during gear changes
provide the maximum possible accelera -
tion. This involving experience is further
enhanced by overrun downshifts
and the
throttle-blip function for uncompromising
driving pleasure.
An additional display in the steering wheel
or either the instrument cluster indicates
whether the SPORT or SPORT PLUS
but -
tons and, with PDK, Launch Control have
been activated. In conjunction with the
optional Porsche Communication
Management (PCM), a special display
enables you to view, store and evaluate
lap times or other driving times. It shows
the total driving time, lap distance, lap
number and lap times recorded so far.

Performance is further intensified by
dynamic gearbox mounts. Read on to find

Dynamic gearbox mounts.
Dynamic gearbox mounts are included
as part of the optional Sport Chrono
Package. They are designed to enhance
both performance and comfort.
The electronically controlled system
minimises the oscillations and vibrations of the entire drive train, especially the
engine.
The gearbox is bolted to the body by t wo
mounts. Like any mass, it obeys the law

of inertia. This means that it will continue
moving in a uniformly straight line unless
some force causes it to change direction. Put more simply: when you are driving
into a bend, the vehicle will follow your
steering but, at first, the mass of the
drive train will not. This means that the
rear of the vehicle will ultimately be
pushed out wards as a result of the drive
train’s force of inertia.
Dynamic gearbox mounts minimise this
effect. Steering angle and both longitudi
-
nal and lateral acceleration are constantly
recorded by sensors. The stiffness and
damping performance of the gearbox
mounts adapt to changes in driving st yle
and road surface conditions, which is
achieved by use of a fluid with magnetic properties. This results in greater

traction, perceptibly more stable handling
under load change conditions and in
fast corners and, in conjunction with the
‘Launch Control’ function for example,
extremely fast acceleration. Using the SPORT or SPORT PLUS but ton
you can switch the dynamic gearbox
mounts from ‘Normal’ to ‘Sport ’ or

‘Per formance’ mode and intensif y your
driving pleasure. In conjunction with optional PCM, the
G -Force graphic on the TFT screen in

the right-hand circular instrument enables
you to view the lateral and longitudinal
forces as they act on the vehicle.
