The new 911 Carrera GTS.
More power. Maximum torque is
reached earlier. An even faster
throt tle response and even
better acceleration. An even
sportier driving experience.
These are the most compelling
at tributes compared with the
911 Carrera S models.
The figures say it all. The upra
ted 3.8litre flat six engine with
direct fuel injection (DFI) now
delivers 300 kW (408 hp), 23 hp
more than the 911 Carrera S.
The Coupé model completes the
0 to 100 km/ h (62 mph) sprint
in 4.6 seconds, the Cabriolet in
4.8 seconds.
Yet, there has been no increase
in fuel consumption or emissions.
This is not a contradiction, but a
combination of dynamics and
efficiency, of sportiness and
ever yday practicalit y. In short, it
is our understanding of the
sportscar concept. We call it
Porsche Intelligent Per formance.
Increased per formance, with
ideas that drive us for ward –
a principle that also reflects
our approach to the chassis
and to safet y. Both models are
equipped as standard with
Porsche Active Suspension
Management (PASM) and
Porsche Stabilit y Management
(PSM). The optional Sport Chrono
Package Plus is the essence of
motorsport, of fering an even
more dynamic tuning of the
chassis and engine setup. In
conjunction with the optional
Porsche Doppelkupplung (PDK),
the Sport Chrono Package Plus
delivers a further improvement
in acceleration: 4.2 seconds
for the Coupé and 4.4 seconds
for the Cabriolet. Gear changes
take place in milliseconds,
with no interruption in the flow
of power. Together, this spells
911 Carrera GTS.
Design.
Three words are enough to
make a clear statement: athletic,
muscular, powerful. The look of
the new 911 Carrera GTS models
leaves no room for doubt. They
are models of clarit y.
Let ’s get straight to the detail,
beginning with the dynamically
accentuated cooling air intakes
in the front apron and the
additional spoiler lip with a
black painted finish. These are
distinctly sport y characteristics,
with components that have
been optimised in the Porsche
wind tunnel to improve aero
dynamic ef ficiency. On the sides
of the vehicle, black sideskirt
trims are a bold indication of
the performance in store. The rear end is just as expres
sive. Compared with the
911 Carrera S, the body is
44 mm wider at the rear axle
and the rear track has been
widened by 32 mm for greater
roll stabilit y and improved
turn in. The 911 Carrera GTS
models are fit ted with 19 inch
RS Spyder wheels featuring
a central locking device. Until
now, this racing wheel design
was exclusive to the 911 Turbo.
The black painted finish on
the centre spokes is also an
unmistakable reference to
motorsport, and a clear signal
of the driver’s racing mentalit y.

Engine.
The message is clear and
un mistakable: force, power
and dynamics. With direct fuel
injection (DFI) and VarioCam
Plus, the uprated 3.8litre six
cylinder rear engine of the
new 911 Carrera GTS models
generates 300 kW (408 hp) at
7,300 rpm.
Words aren’t that important
when something speaks to you from the soul.
Maximum torque is 420 Nm
and both models achieve a top
speed of 190 mph (306 km/ h).
The Coupé accelerates from
0 to 62 mph (100 km/ h) in
4.6 seconds, the Cabriolet in
4.8. The optional Porsche
Doppelkupplung (PDK) further
improves acceleration, reducing
these times to 4.4 and 4.6 sec
onds respectively. The throttle response is even
more direct and acceleration is
even sportier. The engine power
is 23 hp higher than that of the
911 Carrera S. This was made possible by the redesigned
intake manifold, the modified
cylinder heads and the opti
mised engine electronics.
‘ It has a truly insatiable urge for acceleration, but with 408 hp
at the rear axle and such a tremendous amount of grip, that’s
no surprise.’
August Achleitner, Director Product Line Carrera

Intake manifold.
Take a deep breath. The
911 Carrera GTS models are
fit ted with a variable resonance
intake system featuring six
switchable, vacuumcontrolled
valves. In the direct injection system,
the EMS SDI 3.1 engine manage
ment system adjusts the
injec
tion timing individually for
each
cylinder and the injection quanti
t y for each cylinder bank. This
optimises both the combustion
curve and fuel consumption.
A hot film air mass meter takes
care of the airflow, so that the
combustion chambers contain
exactly the right mixture at all
times.
Dual injection is implemented
at engine speeds of up to
3,200 rpm and triple injection
up to 2,500 rpm. The required
quantit y of fuel is distributed
to t wo or three successive
injection processes per cycle.
These valves enable the system
to switch bet ween power
and
torque optimised geometries
for all six air intake tracts to
produce even higher torque in
the mid rev range. The improved
charging of the combustion
chamber is made even more

possible to increase compres

Porsche Doppelkupplung
(PDK).
PDK is available as an option for
the new 911 Carrera GTS mod
els. Gear changes take place in
milliseconds, for vastly improved
acceleration and lower fuel con
sumption.
In total, PDK has seven gears at
its disposal. Gears 1 to 6 have a
sports ratio, with the top speed
being reached in 6th gear. The
7th gear has a long ratio and
Six-speed manual gearbox.
Accurate and involving: the six
speed manual gearbox is the
link to each and every gear.
The cable operated gearshif t
unit is designed for optimum
progression through the gears
and the gear lever is insulated
from the engine and gearbox.
With minimal resistance, the
gear lever throw is short and
precise, enabling a rapid gear
shif t action and positive
response. helps to reduce fuel consump
tion even further. PDK is essen
tially t wo half gearboxes in one
and thus requires t wo clutches –
designed here as a double wet
clutch transmission.
This double clutch provides an
alternating, non positive connec
tion bet ween the t wo half gear
boxes and the engine by means
of t wo separate input shaf ts (input shaf t 1 is nested inside
the hollowed
out input shaf t 2).
The flow of power from the
engine is only ever transmit ted
through one half gearbox and
one clutch at a time, while the
next gear is preselected in the
second half gearbox. During
a gear change, therefore, a
conventional shift no longer
takes place. Instead, one clutch
simply opens and the other
closes at the same time. PDK and the manual gearbox
deliver power directly to the
road. With the optional Sport
Chrono Package Plus (p. 26),
you can make it even more
direct, and even sportier. With a
rush of adrenaline and euphoria,
you are straight into the action.
Precise actions hit the mark sooner.
The same is true of our transmission concepts.

Key features include a digital
and analogue stopwatch, the
SPORT button, a performance
display, a personal memory
function in the Porsche Commu
nication Management (PCM),
and – in combination with
Porsche Doppelkupplung (PDK) –
the SPORT PLUS but ton, and an For maximum dexterit y, PSM
can be set to standby while
the car is still in ‘Sport ’ mode.
For safety, it is set to intervene
automatically only when ABS
assistance is required on both
of the front wheels.
In combination with PDK, the
Sport Chrono Package Plus has
two additional functions that
are activated by pressing the
SPORT PLUS button, for a
sport y drive that borders on
a motorsport experience.
The first function is ‘Launch
Control’ which, for example
when performing laps, helps you
achieve optimum acceleration
from a standing start – a racing

engine and chassis, and delivers
even greater driving pleasure as
a result.
A harder rev limiter is also
applied in the automatic mode
of the optional PDK, while the
gearshif t points are delayed
until the upper rev range. The
shif t times are shorter, the gear
changes sportier. Even at low
rates of deceleration and at high
revs, the system initiates a swift
er, brake induced downshift.
In manual mode, gear changes
are faster and more dynamic.
In ‘Sport ’ mode, the trigger
threshold for PSM is raised for
increased longitudinal and later
al dynamics. Agilit y is enhanced
when braking for corners with
PSM enabling greater manoeu
vrability under braking and exit

response to pedal input, a more
dynamic throt tle map opens the

be the case in Normal mode.
The throttle response is signifi
cantly more immediate and a
harder rev limiter is also applied
in the higher gears. The second function is the
‘motorsport
derived gearshif t
strategy’. Using this, Porsche
Doppelkupplung (PDK) is geared
up for extremely short shif t
times and optimum shift points
for the maximum acceleration
available to the 911 Carrera GTS.
This combination of uncompro
mising and involving perform

Another key component of the
Sport Chrono Package Plus is
the stopwatch mounted on the
dashboard. Porsche Communi

They are designed to cope with
extreme forces and of fer an

short and easy to control.
The brake discs have a diame
ter of 330 mm front and rear –
for formidable braking perform
ance. Their cross drilled design
improves behaviour in wet
conditions. The discs are also
internally vented for bet ter
heat dispersal. Other features
include a powerful nine inch vac
uum brake booster for reduc
ing pedal effort, and integral
air spoilers for enhanced air
flow in the brake cooling ducts.

Porsche Ceramic Composite
Brake (PCCB).
Motorsport is the ultimate test
of braking performance. On
request, we can provide you
with a brake system that has
already had to cope with the
harshest requirements of motor
racing – a brake system fit ted
in the cars competing in the
Porsche Mobil 1 Supercup, for
example: the Porsche Ceramic
Composite Brake (PCCB).
The ceramic discs have a dia
meter of 350 mm front and
rear. The discs are made from
a specially treated carbon fibre
compound that is silicated in four
piston units at the rear. The
resulting brake forces are both
extremely high and remarkably
consistent. The pedal response
is fast and precise with only
moderate input required.
PCCB enables shorter braking
distances in even the toughest
road and race conditions. Excel
lent fade resistance ensures
greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is
the total weight saving of
approximately 50 % over metal discs with similar construction
and dimensions. As well as
enhancing per formance and
fuel economy, this represents
a major reduction in both the
unsprung and rotating masses.
This, of course, offers major
benefits in terms of comfort
and road holding on uneven
road surfaces as well as general
handling and agilit y.
Please note that circuit racing,
trackday use and other forms
of per formance driving can
significantly reduce the service
life of even the most durable pads and discs. As with conven
tional high per formance braking
systems, we recommend that
all brake components be profes
sionally inspected and replaced
where necessary after every
track event.
