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.

Boxster S
Why live life on standby?
Boxster S.Life cannot be lived too intensely. Driving
should be truly engaging. This is the core
message of the new Boxster S.
Producing 232 kW (315 hp) at 6,700 rpm,
its 3.4-litre flat-six engine with DFI and
VarioCam Plus delivers a might y 37 kW
(50 hp) and 80 Nm more than the engine
in the Boxster. Maximum torque of 360 Nm
is available from 4.500 rpm to 5.800 rpm. The sprint from 0 to 62 mph (0 to

100 km/ h) is completed in 5.1 seconds
and a top speed of 173 mph (279 km/ h)
can be achieved.
Nevertheless, the dynamic per formance
of the new Boxster S can be further
enhanced. With the optional Porsche
Doppelkupplung (PDK) transmission and
the optional Sport Chrono Package, the
0 to 62 mph (0 to 100 km/ h) acceleration
time drops to a mere 4.8 seconds. Option -
al
Porsche Torque Vectoring (PT V) offers
increased agilit y and driving pleas
ure at
the same time as improving traction and
handling. The Boxster S delivers excite -
ment at every t wist and turn. Extra horsepower demands a higher

level of safet y. The front brake discs are
15 mm larger in diameter than those on
the Boxster and the brake calipers are
finished in red. 19-inch Boxster S light-
alloy wheels with a double-spoke design
are fit ted as standard and create an
exceptionally powerful presence for
a roadster. The slats on the front air intakes are

finished in black. The Boxster S comes
with Bi-Xenon headlights as standard.

Resonance intake manifold.
The resonance effect, where the air
mass inside the intake manifold is
caused to oscillate is used to optimise
the induction process at all engine
speeds. The engine in the Boxster S is
additionally equipped with a switchable
resonance valve.
The results are high torque, a flat ter
torque curve and high power output.
The sound produced is characteristically
resonant and deep, as you would expect
of a Boxster.

Direct fuel injection (DFI).
Direct fuel injection (DFI) is featured
as standard in both Boxster models.
Multi-hole injectors deliver fuel directly
into the combustion chamber with milli -
second precision. The injection pattern
has been optimised for torque, power
output, fuel consumption and emissions.
With direct injection, the engine manage -
ment system regulates injection timing
individually for each cylinder, as well as
the injection rate for each cylinder bank.
This optimises the combustion process
and therefore fuel economy. Depending
on the engine operating conditions, multi -
ple fuel injections can take place on each operating cycle. This allows the cata
-
ly tic converter to reach normal operating
temperate sooner after a cold start and a
higher maximum torque to be achieved.
DFI improves the internal cooling of the
combustion chamber by having the
mixture prepared directly in the cylinder.
This allows for a higher compression ratio,
which helps to deliver higher power output
at the same time as enhanced engine
efficiency. Injection is regulated by the
electronic engine management system
and emissions are monitored by the stereo
Lambda sensors.

Engine management.
The electronic engine management
system ensures optimum engine perfor -
mance at all times. It regulates all
engine-related functions and assemblies.
The results are optimum power output
and torque with comparatively low fuel
consumption and emissions. Another function is the cylinder-specific
knock control. Since engine cylinders
never all work under exactly the same
conditions, the knock control function
monitors each one separately. The igni
-
tion point is shifted individually, as and
when necessary, to protect the cylinders
and pistons at high engine speeds and loads. For compliance with EU Stand
-
ards, the on-board diagnostics detect
any faults and defects that may occur in
the exhaust and fuel systems and then
notify the driver immediately. This also
prevents increased pollutant emissions
and unnecessary fuel consumption.
SPORT button.
The SPORT but ton on the centre console
is fit ted as standard. When selected,
Sport mode is activated to provide
greater response and enhanced driving
pleasure. Throttle response becomes
even more direct, the rev-limiter is
adjusted to a harder set ting and engine dynamics are tuned for performance

driving. The auto start/stop function is
also deactivated. With the optional Porsche Doppelkupplung
(PDK) transmission, the shift points are
reconfigured are reconfigured to operate at higher engine speeds. Shift times are
reduced and gearshifts become firmer
and more immediate, while throttle-blip
downshifts are accompanied by an
emotive engine sound. Coasting mode
(p. 44) is deactivated automatically.

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.

Coasting.
The coasting function available with
Porsche Doppelkupplung (PDK) enables
you to save even more fuel where the
situation allows. The engine is decoupled
from the transmission to prevent
deceleration caused by engine braking.
In this way, optimum use is made of
the vehicle’s momentum, allowing it to
coast for longer distances.
For example, you may want to slow down
from 60 mph to 40 mph in anticipation
of the change of speed limit ahead. As
you ease off the accelerator pedal, PDK
deselects the current gear automatically
and you begin to coast in neutral until
you have reached your desired speed. As
soon as you operate the accelerator or brake pedal, PDK re-engages the appro
-
priate gear within fractions of a second.
The process is smooth and seamless
thanks to the extremely fast clutch.
Another way to reduce fuel consumption
is to utilise the coasting function on
downhill gradients that are gentle enough
for you to maintain a constant speed.
Efficient on long journeys, such as on the
motorway, PDK remains ready to respond
as swiftly and precisely as you would
expect.
In short, driving in coasting mode makes
a real impact on fuel consumption with -
out any need for compromise on comfort
or sporty performance.
With the SPORT but ton selected, the full
advantages of the new version of PDK
are brought into play: a more immediate
response to throt tle inputs, even shorter
shift times and swift, throttle-blip down -
shifts on overrun and when braking –
always accompanied by an emotive engine
sound.
With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport- derived gearshif t strategy’
functions (p. 63) for even faster gear
changes and the best possible per formance
thanks to a boost in torque during upshift
phases. Overrun downshifts provide
extremely sport y braking and acceleration
for added excitement.

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.

Porsche Active Suspension
Management (PASM).
Optional PASM, the electronic damping
control system, suits the new Boxster
models down to the ground. PASM
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,

Chassis
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.

Chassis
In ‘Sport ’ mode, the suspension is set
to a harder damper rating. On uneven
roads, PASM immediately switches
to a softer rating, thereby improving
contact bet ween the t yres 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 switches to a

harder rating to increase driving stability
and road safet y. The results are tangible: increased driving
stability, enhanced driving pleasure and
improved performance.
Steering.
One definition of efficiency is a system

that works only when it is needed, and then
does so in a particularly effective way.
This was the guiding principle for our
engineers in the development of the new
electromechanical steering system.
Whereas a conventional hydraulically
assisted steering system draws engine
power continuously, the electric motor
in the electromechanical arrangement
uses energy only when the steering

wheel is actually turned. As a result, fuel
consumption is reduced and the absence of hydraulic fluid eliminates the need for
servicing, both of which also have benefits
for the environment.
The Boxster concept was designed to of fer
outstanding cornering performance. The
new steering system delivers and it even
improves the typical Porsche steering feel. It features a variable steering ratio and
responds precisely and directly as well as
providing customary agility, a high level of
comfort and plent y of direct feedback from
the road. Power steering Plus, the optional
speed -sensitive power-steering system, mini
