equipment
Are you ready to assert your independ -
ence? The ignition lock, as ever, is on the
lef t. The three -spoke sports steering
wheel falls perfectly to hand. As is t ypical
of a Boxster, there are three circular dash -
board instruments. The instrument on the
right is now a 4.6-inch TFT screen that
shows information from the on-board com -
puter or audio information from the
CDR
audio system, which is fit ted as stan dard.
An inconspicuous shroud shades the
instruments for optimum visibility.
The steering wheel rim, gear lever/selec -
tor and door pull inlays are finished in
tactile leather. Silver-coloured details add
to the refined tone; these include the
one of many principles that we’ve trans
-
ferred from the racetrack to the road.
The door st yling is similarly dynamic. The
door pulls mirror the lines of the centre
console and blend seamlessly into the
distinctive design. The door storage com -
partments are sweeping and practical.
As you would expect from a sports car,
the driver sits low down. Sports seats
are fit ted as standard. The athletic pro -
portions of the Boxster models made
it possible to introduce a new interior
architecture. The result is a feeling of
space and light without compromising
the authentic roadster experience.
How much independence do we really have?
It’s a question of inner attitude.
Design.
Interior.
The interior of the Boxster models delivers
exactly what the exterior promises. Light,
uncluttered and defined; every thing is
conceived with one goal in mind: the per -
fect drive.
The power, the contouring, the driver’s
vision, indeed the entire concept, are all
drawn in the direction of travel. The intelli -
gent operating concept and the logical
arrangement of the controls keep the driv -
er’s concentration purely on the road. The
ascending centre console cocoons the
driver perfectly and reduces the distance
from the steering wheel to the gear lever
for fast and ergonomic gearshifts. It ’s just

The hood on the 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 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.
Porsche Active Suspension Management
(PASM) offers continuous adjustment of
damping forces based on the selected
mode. Dynamic performance can be fur
-
ther improved with optional Porsche
Torque Vectoring (PTV).
The optional Sport Chrono Package
includes dynamic gearbox mounts. They
contain a fluid with magnetic properties,
which enables them to adapt instantly to
driving conditions and counteract the
effects of inertia. The results are percep -
tibly more stable handling during perfor
-
mance driving, as well as a higher level of
ride comfort.

Engineering.
A series of innovative technologies is
key to achieving exemplary efficiency.
As standard, these include the auto
start /stop function, electrical system
recuperation (p. 42), energy-saving
electrome chanical power steering, intelli -
gent thermal management and, in conjunc -
tion with PDK, the coasting function. The
result is a significant reduction in
fuel consumption and, therefore, a reduc -
tion in CO
2 emissions of up to 16 % com-
pared with the previous model (depending
on the equipment variant).

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
VarioCam 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).

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 millisec-
onds, delivering gear changes with no loss
of drive.

Porsche Doppelkupplung (PDK).
Available as an option for the Boxster
models is 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 man-
ual 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 sports
ratio and top speed is reached in 6th gear.

Six-speed manual gearbox.
Both 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 ascending 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. In con-

selected and the driver’s st yle becomes
more assertive, PASM switches to a
harder rating to increase driving stability
and road safet y.
In ‘Sport ’ mode, the suspension is set
to a harder damper rating. On uneven

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.
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. 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.
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.

of the entire drivetrain, especially the

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
