2013 PORSCHE BOXSTER S ESP

2021
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).

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.
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. And we do this always on the
proviso that high power is achieved 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
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 to fully enjoy every
corner and maintain excellent control
over the vehicle.
Always mid- engined.
Never middle ground.
Boxer engines.
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.

2 Boxster S t win tailpipemonitors 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 Boxster
models is the sports exhaust system
including sports tailpipe. It produces an
even more resonant Porsche sound.
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 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)

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

During sporty driving, thermal manage -
ment also acts to reduce temperatures
so that a high level of performance is
maintained.

loads. For compliance with EU Standards,
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.
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

The results are optimum power output
and torque with comparatively low fuel

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.
For fuel consumption, CO2 emissions and efficiency class please refer to page 131.
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-
junction with the optional Sport Chrono

accelerator or brake pedal, PDK re-en -
gages the appropriate gear within frac -
tions 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.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 100 km/ h to 80 km/ h in anticipa -
tion of the change of speed limit ahead.
As you ease off the accelerator pedal,
PDK deselects the current gear automa -
tically and you begin

With the optional Sport Chrono Package,
PDK is enhanced by the ‘Launch Control’
and ‘motorsport- derived gearshif t strat-
egy’ functions (p. 65) 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 sport y braking and
acceleration for added excitement.
