A higher form of intelligence.
A pure expression of independence.
Has it really been 15 years since the
debut of the original Boxster? An instant
design classic, a powerful mid-engined
sports car, a purebred roadster. It was
clear the Boxster did full justice to its
predecessors in the Porsche lineage.
As Porsche engineers planned the third-
generation Boxster, the question was,
how could it continue to do so in the
future? How could the Boxster evolve into
something even more evocative of the
essence of Porsche performance? The
answer was found where it always is at
Porsche: in the harmonious blending of
style, functionality, and innovation. The
new Boxster is nothing less than the total
refinement of Porsche’s belief of what a
roadster should be, honed and sharpened
to give it a completely new expression.
We achieved this with Intelligent
Performance. With increased power
that is delivered more efficiently.
With innovative technologies, the
strategic use of lightweight materials
in its construction, and with an
exterior and interior design that
puts aesthetically appealing lines
and curves in all the right places.
More independent of spirit than ever
before, the Boxster is now even more
powerful, visceral, and intense.

Design
Exterior
In elevating expectations of how the
Boxster should perform, Porsche has
once again succeeded in creating
an icon of automotive design. It
is a Porsche that continues to
epitomize the feeling of power in
its most efficient form, of pleasure
heightened by functional excellence.
The vertical contour of the headlights
was inherited from Porsche race cars
of the 1960s and 1970s. The new
Boxster may be infused with the genes
of past generations, but it ushers in a
new and forward-looking design ethos.
Large air intakes give the front a
powerful appearance, while the side
contour hints at the performance within.
The long wheelbase and low, raked
windshield are integral to forming the
stretched, wedge-shaped silhouette.
With the top up, this impression is
reinforced by the extreme roofline.
Large wheels, up to 20 inches in size,
emphasize the Boxster’s wide track
and help to achieve a completely
new level of athletic performance.
The distinctive shoulder lines give
further emphasis to the wheels,
which, in combination with the side
air intakes and the mid-engine layout,
are reminiscent of the 718 RS 60
Spyder, a lightweight mid-engined
Porsche from the 1960s that achieved
remarkable success in endurance racing
and hill-climbing championships.
The precise lines are more sharply
defined than on any previous Porsche
design, and run elegantly across the
fenders to the rear. It’s an imposing
look that makes the new Boxster
unique among other Porsche models.

In typical Porsche fashion, it has a
clear function. The dynamic contouring
improves airflow to the side air intakes.
Independence
| Design
At the top, it leads into a precise
longitudinal edge and, at the bottom, it
is underlined by the sculpted door-entry
guard. The exterior mirrors are mounted
directly on the doors to enhance
aerodynamic flow and reduce wind noise.
The rear spoiler is not only a visual
treat, but also deploys automatically
to reduce lift. Aerodynamics and
aesthetics are combined to superb
effect. Retracted, the spoiler separation
edge makes a seamless transition to
the LED taillights. The narrow direction
indicators appear to extend the rear
spoiler further. Each taillight sweeps
around the central brake light and
accentuates the contours of the entire
unit. For a striking effect, the reverse
and rear fog lights are arranged in the
middle underneath the rear wing. It’s a
lighting concept without precedent, the
result of Porsche’s modern use of form.
The diffuser with stainless steel tailpipe
(dual-tube on the Boxster S) integrated
into the center adds the finishing touch
to the powerfully designed rear end.
The new Boxster is clearly inspired
by Porsche history. But it is not a
mere exercise in retro styling. It is a
completely new interpretation of the
mid-engine Porsche roadster, with a clear
focus on what Porsche engineers believe
the future of the roadster should be.

Interior
The interior of the new Boxster
delivers exactly what the exterior
promises—a light, uncluttered, and
defined design, existing to fulfill
one single aim: the perfect drive.
The entire concept—from the power
and contour to the driver’s vision—are
all drawn in the direction of travel.
The Boxster driver’s concentration
is kept purely on the road, thanks
to the intelligent operating concept
and the logical arrangement of the

distance from the steering wheel to
the shift lever for fast and ergonomic
gearshifts. It’s just one of many ways
that Porsche transfers its experience
from the racetrack to the road.
The door styling is similarly dynamic.
The door pulls mirror the lines
of the center console and blend
seamlessly into the overall design.
The door storage compartments
are sweeping and practical.
The athletic proportions of the new
Boxster models make it possible to
introduce a new interior architecture. The
driver’s seating position is low, and from
that vantage point, there is a feeling of
space and light without compromising
the authentic roadster experience.
Ready to assert your independence?
You’ll find the ignition located to the
left of the steering column, reflecting
Porsche’s racing heritage. The three-
spoke sport steering wheel fits
perfectly in your hands. Facing the
driver is a cluster of three large circular
instruments. The instrument on the
right is now a 4.6-inch TFT screen that
shows information from the onboard
computer or information from the audio
system. An inconspicuous shroud shades
the instruments for optimal visibility.
The steering wheel rim, shifter lever/
gear selector, and door-pull inlays
are finished in tactile leather. Silver-
colored details add to the refined tone.
These include the instrument cluster
trim strip, the side and center air-vent
surrounds, and the center console.

Everything done to create the new
Boxster has a sole purpose: to bring
the driver closer to the road. Its 2.7-
liter flat-six engine with Direct Fuel
Injection (DFI) and VarioCam Plus
produces 265 horsepower at 6700
rpm, with a maximum torque of 206
lb.-ft. available from 4500–6500 rpm.
The top track speed is 164 mph. With
the precisely geared six-speed manual
transmission fitted as standard, the
Boxster accelerates from 0–60 mph
in just 5.5 seconds. With the optional
7-speed Porsche Doppelkupplung (PDK)
and the optional Sport Chrono Package
including dynamic gearbox mounts,
this time is cut to 5.2 seconds.
Power is transmitted to the road by
18-inch Boxster wheels. Their distinctive
five-spoke design affords an unobstructed
glimpse of the braking system’s black,
four-piston, aluminum monobloc fixed
calipers. The optional Porsche Ceramic
Composite Brakes (PCCB) provide
motorsport braking performance.
The slats on the front air intakes are
painted to match the exterior color. The
unmistakable Porsche sound is emitted
via a central exhaust tip in brushed
stainless steel.

| Boxster S
The engine is in the middle. But
everything else is in the extreme. The
Boxster S is an even more vehement
interpretation of the Porsche roadster.
It has been engineered to provide an
immediate, intense experience.
Producing 315 horsepower at 6700 rpm,
and a maximum torque of 266 lb.-ft.
at 4500–5800 rpm, the 3.4-liter flat-
six engine with DFI and VarioCam Plus
delivers an added 50 horsepower and 50
lb.-ft. of torque more than the engine in
the Boxster. The sprint from 0–60 mph is
completed in just 4.8 seconds, and a top
track speed of 173 mph can be achieved.
Yet even this exceptional level of
dynamic performance can be further
enhanced. With the optional Porsche
Doppelkupplung (PDK) transmission and
the optional Sport Chrono Package,
the new Boxster S is capable of a
0–60 sprint in a mere 4.5 seconds.
Optional Porsche Torque Vectoring
(PTV) offers increased agility and
driving pleasure at the same time as
improving traction and handling.
Extra horsepower demands extra
stopping power. The front brake discs
are 0.59 of an inch 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 create
an exceptionally powerful presence.
The slats on the front air intakes are
finished in black. The Boxster S comes
with Bi-Xenon™ headlights as standard.
The centrally positioned dual-tube
twin tailpipe in brushed stainless steel
sounds as impressive as it looks.
In the interior of the Boxster S, the
door panel armrests and the storage
compartment lid in the center
console are additionally upholstered
in leather. The rev counter has an

Porsche first explored the mid-mounted
engine in the 1950s, in sports cars such
as the 550 Spyder. The advantages were
obvious. The concentration of mass
close to the center of the vehicle and
the low center of gravity heightened the
car’s cornering dynamics. At the same
time, evenly distributing the engine’s
weight between the front and rear
axles created handling characteristics
that were equally well-balanced. The
driver of a mid-engine Porsche could
wring satisfaction from every corner.

Engine
Porsche’s mid-engined design proved
to be a key factor in countless racing
victories. On some of the world’s most
famous racing circuits, Porsche drivers
often found they could out-corner their
heavier, more powerful competition. In the
1960s, the 718 RS 60 Spyder solidified
the reputation of Porsche’s mid-engined
race cars as “giant killers,” with numerous
wins in hill-climbing and endurance events.
For us, there are many reasons to
remain faithful to the mid-mounted
engine concept, to keep transferring
performance from the racetrack
to the road, and to continue to
combine tradition with innovation.
How do we do it? Through Intelligent
Performance, our commitment to high
power with comparatively low fuel
consumption and emissions figures.
With this aim, we developed two
compact and lightweight boxer engines
able to deliver high levels of power and
efficiency simultaneously. Both engines
are equipped with efficient 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 button on the center console
makes engine performance even
more dynamic for driving pleasure
at the limits of performance. Let’s

Direct Fuel Injection (DFI)
Information Provided by:
Direct Fuel Injection (DFI) is featured as
standard in both Boxster engines. Multi-
hole injectors deliver fuel directly into the
combustion chamber with millisecond
precision. The injection pattern has been
optimized for torque, power output,
fuel consumption, and emissions.
With direct injection, the engine
management system regulates injection
timing individually for each cylinder,
as well as the injection rate for each
cylinder bank. This optimizes the
combustion process and enhances
fuel economy. Depending on the
engine operating conditions, multiple
fuel injections can take place on each
operating cycle. This allows the catalytic
converter to reach normal operating
temperature sooner after a cold start
and to achieve a higher maximum torque.
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 each stereo
lambda sensor monitors emissions.
24
VarioCam Plus
Information Provided by:
VarioCam Plus is a two-in-one
engine concept for adjusting the
intake camshafts and switching
the lift of the intake valves.
Performance
|
Engine
The system first differentiates between
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.
The result? Instant acceleration and
extremely smooth running.
Integrated Dry-Sump Lubrication
Integrated dry-sump lubrication
ensures a reliable supply of oil even
when a performance driving style is
adopted and the vehicle is experiencing
powerful lateral acceleration. It also
has additional cooling functions.
The oil tank is located in the engine,
eliminating the need for an external oil
tank, and saving both space and weight.
To help reduce power losses and increase
efficiency, an electronically controlled
oil pump supplies the lubricating points
inside the engine when required. This
results in an optimal supply of oil, lower
fuel consumption, and reduced emissions.
26
Thermal Management
Information Provided by:
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
consequent reduction in friction also
contributes to reducing fuel consumption*
and CO2 emissions. During performance
driving, thermal management also acts
to reduce temperatures so that a high
level of performance is maintained.
A cross-flow cooling system supplies
each engine cylinder uniformly with
coolant, which helps to protect the
valves against thermal overload
and premature wear. Keeping each
cylinder cool improves combustion and
keeps emissions, fuel consumption,
and noise comparatively low.
Performance
|
Engine
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 twin (Boxster S) tailpipe. The stereo
lambda control circuitry monitors each
cylinder bank separately. For each
exhaust tract, four corresponding
oxygen sensors regulate the composition
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 sport
exhaust system, including Sport
tailpipe. It produces an even more
resonant Porsche sound.
Sport Button
Select the Sport mode by pressing the
Sport button on the center console.
Throttle response becomes even more
direct, the rev limiter is adjusted to a
harder setting, and engine dynamics
are tuned for performance driving.
The Auto Start Stop function is
also deactivated. Coasting mode is
also deactivated automatically.
With the optional Porsche Doppelkupplung
(PDK) transmission, the shift points
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.
Auto Start Stop Function
This fuel-saving innovation is designed
primarily for use in congested
traffic. The Auto Start Stop function
switches off the engine when you
stop, select Neutral, and release the
clutch pedal. In cars with Porsche
Doppelkupplung (PDK), it is simply a
case of applying and holding the brake.
All audio and communication systems
remain switched on, as does the air-
conditioning system. The engine will
restart as soon as you operate the
clutch or, in cars with PDK, release
the brake. The Auto Start Stop
function can be deactivated and
reactivated using a separate button
on the center console. The function
may be deactivated automatically
under particular circumstances, such
as when the Sport button is selected
or there is low battery charge.
*Note: Please see fuel economy estimates on page 108.
Electrical System Recuperation
For enhanced efficiency, the new Boxster
models are equipped with intelligent
electrical system recuperation. The
vehicle battery is recharged by the
generator, predominantly under braking.
Thanks to this selective recharging,
when you require full driving power,
the maximum possible output can
be directed straight to the road.

Porsche Doppelkupplung (PDK)
Available as an option for the new Boxster
models is a completely re-tuned 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 consumption,
and a distinct increase in comfort.
In total, PDK has seven forward gears at its
disposal. Gears 1 to 6 have a sport 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
The design of PDK is similar to two
conventional transmissions 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
preselects 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 power.

of PDK are brought into play: a more
immediate response to throttle inputs;
even shorter shift times; and swif t,
throttle-blip downshifts on overrun
and when braking. Even the sound
you hear from the exhaust is altered
to elicit a more visceral response.
With the optional Sport Chrono Package,
PDK is enhanced by the Launch Control
and motorsport-derived gearshift strategy
functions, for even faster and firmer
gear changes and the best possible
performance, thanks to a boost in torque
during upshift phases. Overrun downshifts
provide extremely sporty braking and
acceleration for added excitement.
Coasting
A coasting function within the Porsche
Doppelkupplung (PDK) helps save even
more fuel when the situation allows.
The engine is decoupled from the
transmission to prevent deceleration
caused by engine braking. So the
vehicle’s momentum is allowed to carry
it for longer distances, conserving fuel.
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 appropriate
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 activate the coasting function
on downhill gradients that are gentle
enough for you to maintain a constant
speed. Efficient on long uninterrupted
drives such as an interstate journey,
PDK remains ready to respond as swiftly
and precisely as you would expect.
In short, driving in coasting
mode increases fuel efficiency
without any need for compromise
in comfort or performance.
