2013 PORSCHE 911 GT3 weight

The new 911 GT3 I 11
For the first time, 7­speed Porsche Dop ­
pelkupplung (PDK) is fit ted as standard,
with short ratios designed exclusively for
the 911 GT3. The shift throws of the
gearshift paddles on the steering wheel
are even shorter and gear changes are
even more dynamic so as to provide
even better acceleration.
The rear of the new 911 GT3 is 44 mm
wider than that of the previous model. In
addition, the track at the rear axle has
been widened by 31 mm, which improves
lateral dynamics. The addition of 100 mm
to the wheelbase has significantly
increased driving stabilit y. Fit ted as
standard, Porsche Torque Vectoring Plus (PT V Plus) helps to ensure even greater
stability when cornering, while rear
­axle
steering provides extraordinar y agilit y
and more dynamic overtaking manoeu ­
vres on the racetrack.
The new 911 GT3 explores the lower
limit in terms of fuel consumption
thanks to intelligent technologies such
as PDK, DFI and a low vehicle weight.
All in all, the new 911 GT3 is a precision
instrument, giving you everything you
could need to push your own boundaries.
Indeed, part of the brief for our engineers
was to build a manageable sports car
that feels at home on the racetrack, yet can be taken to brand new sport y
destinations by drivers who aren’t able

to tackle the Northern Loop of the
Nürburgring day in day out.
The new 911 GT3 preserves tradition for
the future – a principle that the 911 has
embodied for 50 years. It aims to push
the boundaries of what is possible, on
each new day.

Aerodynamics and design.
Clear rules apply at the limit. One of
them being that a sport y design alone is
not enough. Each detail must also serve
a particular function.
The new front end has further improved
the aerodynamics of the centre radiator.
This is revealed to the eye by the custom ­
ary 911 GT3 air outlet to the front of the
luggage compartment lid. Together with
the wider front spoiler lip, it provides
much more downforce at the front axle.
All cooling air openings are protected by
titanium ­coloured air intake grilles. These are an indication of what lies at the
centre of the concept: motorsport.
Bi
­Xenon headlights are fit ted as stand ­
ard. Their design is reminiscent of
Porsche motorsport classics. Sleek
direction indicators, daytime running
lights and position lights boasting LED
technology create that contemporary
contrast. LED headlights are also
available as an option.
The mirror base of the SportDesign
exterior mirrors reflects the v ­shaped
st yling of the wheel spokes and air
intake opening in the front end. Three words sum up the rear: wider,
sleeker, sharper. LED taillights emphasise
the horizontal contouring of the rear.

The central t win tailpipe of the sports
exhaust system is painted black.
From afar, the fixed rear wing visibly
distinguishes the 911 GT3 from a 911.
The wing, wing uprights and rear lid are
made of a light weight synthetic material.
The ram ­air collector intake is now a
single unit.
That ’s the downforce and engine air
induction prerequisites fulfilled. The
aerodynamics have also been enhanced by the new underbody panelling with
diffuser function at the rear. The result is
considerable downforce for considerable
driving stabilit y and a drag coefficient

of 0.33.
The new 911 GT3 has an even sturdier
and safer stance on the tarmac. Nowhere
does it feel more at home than at the
limit.

Engine.
Located just above the tarmac and posi­
tioned low down in the rear is the newly
developed water ­cooled six ­cylinder alu ­
minium engine with four valves per cylin ­
der, VarioCam and a separate engine
oil tank.
This high ­revving concept promises excep ­
tional
power. The engine has a maximum
speed of 9,000 rpm.
Maximum torque
of 440
Nm is available at 6,250 rpm and
maximum power output is
produced
at 8,250 rpm. Particularly light weight
Two hundredths of a second are worlds apart.
What are we waiting for?
titanium connecting rods facilitate the
unit’s impressive rpm capability.
The engine taps into its capacit y of
3.8 litres to generate a maximum power
output of 350 kW (475 hp). This corre ­
sponds to a power output per litre of
92 kW (125 hp). The new 911 GT3 tears
acceleration limits asunder: it sprints
from 0 to 100 km/ h in just 3.5 seconds –
0.6 seconds faster than its predecessor.
The 200 km/ h mark is also reached
0.9 seconds sooner, after precisely
11. 4 s e c o n d s .
How is that possible? Thanks to a weight
­
to ­power ratio of only 4.1 kg / kW
(3.0 kg / hp), a great deal of fine ­tuning
and the short transmission ratios of
Porsche Doppelkupplung (PDK). These
increase torque and acceleration potential
in all seven gears. Limits? The new
911 GT3 accepts that only the other side
of the 315 km/ h mark is beyond its reach.
Direct fuel injection (DFI), fitted in a
911 GT3 model for the first time, makes
a decisive contribution to the efficiency
of the engine – and its power output. It does it with millisecond precision and

a pressure of up to 200 bar for optimum
mixture formation and combustion in the
combustion chamber.

2 emissions and efficiency class, please refer to page 91.

Chassis.
The chassis of the new 911 GT3 has
been engineered to meet the challenging
demands of motorsport – and for this
reason it also provides extremely sport y
day ­to ­day driving. The ride height of the
new 911 GT3 is 30 mm lower than that
of the 911 Carrera. In conjunction with
a series of specifically tuned chassis
components, this offers extraordinary
agilit y, a high degree of driving safet y and
stable handling, particularly in corners.
The independent front suspension
combines McPherson ­type struts with

longitudinal and transverse links. The
rear axle has a multi ­link suspension,
following the LSA (Light weight, Stable,
Agile) concept. Height, camber, track
and the anti ­roll bars can be individually
adapted for use on the racetrack.
Additional ball joints on the front and
rear axles help to establish a particularly
firm connection between the chassis
and the body.
An optional lift system at the front axle
raises the front end by 30 mm. Operable
up to a speed of approximately 50 km/ h, it minimises the risk of grounding on
kerbs, ramps and car park entrances.
Rear-axle steering.
Fit ted as standard, the new rear
­axle
steering combines performance and
everyday practicality. An electromechani ­
cal adjustment system at each rear wheel
enables the steering angle to be adapted
based on the current driving situation,
steering input and vehicle speed.
The advantage for day ­to ­day driving:
during low ­speed manoeuvres, the

system steers the rear wheels in the
opposite direction to that of the front wheels. This has the virtual effect of
shortening the wheelbase. The turning
circle is reduced to make it easier to
park. The advantage for sport y driving:
during high
­speed manoeuvres, the sys ­
tem steers the rear wheels in the same
direction as that of the front wheels.
Driving stabilit y is increased by the virtual
extension of the wheelbase and agilit y
is enhanced by the simultaneous steering
of the front and rear axles, especially
during overtaking manoeuvres on the
racetrack.

Brakes.
At the limit, you need one thing above all:
reserves. Not only for power, but for
safet y, too. This is possible only with a
race­proven technology on which the
driver can depend at all times. Only this
can free up extra room for manoeuvre,
especially in the red zone.
The new 911 GT3 is therefore equipped
with a particularly powerful yet light ­
weight brake system with a specifically
Driving at the limit.
But never beyond.
matched brake booster. The red six ­piston
aluminium brake calipers on the front axle
and the four ­piston equivalents at the
rear are designed as monobloc units. This
makes them tougher and enables a more
rapid response and release of the brake,
even under heav y loads.
That’s not all. The brake dimensions on
the new 911 GT3 have been enlarged to
cope with the increase in engine power.
The brake discs are 380 mm in diameter not only at the front but now also at

the rear. Thanks to their t wo ­piece
construction with cast iron brake discs
and aluminium brake chambers, they
reduce weight and thus the unsprung
and rotating masses. The brake discs
are cross ­drilled and internally vented
for powerful braking even in adverse
weather conditions. Or when pitted
against the challenges of motorsport.

Porsche Ceramic Composite Brake
(PCCB).
From the start, Porsche has been synony­
mous with motorsport. Ever since 1948,
we have pushed the boundaries of
dynamic performance on the racetrack.
We have taken the experience we have
gained and applied it directly to the road.
The optional Porsche Ceramic Composite
Brake (PCCB) is a fine example. In numer ­
ous race series, including the Porsche
Mobil 1 Supercup, it has been proven to
withstand the harshest demands of the
track.
Nevertheless, resting on our laurels isn’t
our st yle. That ’s why we have also adapt ­
ed PCCB dimensions to match the perfor ­
mance capabilities of the new 911 GT3. The cross
­drilled ceramic brake discs are
now 410 mm in diameter at the front
and 390 mm at the rear for even more
formidable braking performance.
The use of six ­piston aluminium mono ­
bloc fixed brake calipers on the front
axle and four ­piston units at the rear –
all finished in yellow – ensures extremely
high brake forces which, crucially, are
exceptionally consistent.
PCCB enables shorter braking distances
in even the toughest road and race
conditions. Excellent fade resistance

provides greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately
50 % lighter than standard discs of a
similar design and size. As well as
enhancing performance and fuel econ­
omy, this represents a major reduction
in unsprung and rotating masses.
This results in bet ter road holding and
increased comfort, particularly on uneven
roads, as well as greater agilit y and
improved handling.
Please note that circuit racing, trackday
use and other forms of performance
driving can significantly reduce the
service life of even the most durable
pads and discs. As with conventional high
­performance braking systems, we
recommend that all brake components
be professionally inspected and replaced
where necessary after every track event.
Driver and passenger airbags.
We use advanced airbag technology in
the form of full ­size driver and front pas ­
senger airbags, which are inflated in t wo
stages depending on the severit y and
t ype of accident (e.g. frontal or offset
frontal). In less serious accidents, the air ­
bags are only partially inflated, thereby
minimising discomfort to the occupants.
Porsche Side Impact
Protection System (POSIP).
POSIP, fit ted as standard, consists of
side impact protection beams in the
doors and t wo side airbags on each side:
an integral thorax airbag is located in
each seat side bolster and an upwards ­
inflating head airbag is incorporated
within each door.
Additional safety features include the
headrests which form an integral part of
each seat, an energy ­absorbing steering
column, three ­point seat belts with pre ­
tensioners and force limiters and energy ­
absorbing elements in the dashboard.

Interior materials.
Durability, stability and resilience. These
are the essential ingredients for materials
in a sport y environment. It is an environ­
ment dominated by Alcantara, leather and
interior parts in Galvano Silver as well
as brushed aluminium. Here, materials
must be practical – and top qualit y. The
fact that they also have the motorsport
feel is a welcome bonus.
Alcantara is easy to grip and maintain.
For this reason, it is mainly found in
places where there is direct contact: on
the steering wheel rim and gear selector
as well as on the door handles, door
armrests and lid of the centre console
storage compartment. The rooflining
and C ­pillar trims are also finished in
A lcantara.
Steering wheel.
Change gear like a motorsport profes ­
sional with the GT3 SportDesign steering
wheel with gearshift paddles. In the new
911 GT3, the shift throw of the paddles
has been further reduced by 50 %.
Gearshifts become even more direct
and precise.
The GT3 SportDesign steering wheel
offers up to 40 mm of height and reach
adjustment. The steering wheel rim
in black Alcantara is easy to grip and
remains in firm hands, even on sport y
drives.
The top centre marking is another
characteristic feature.
Sports seats Plus.
Sports seats Plus are fit ted as standard
in the new 911 GT3 and come equipped
with elevated side bolsters, electric seat
height and backrest adjustment and
manual fore/aft adjustment. The seat
side bolsters are upholstered in leather
and the seat centres are lined in black
Alcantara. The headrests are embroi ­
dered with the ‘GT3’ logo.
The side bolsters on the seat squab and
backrest have a firm, sport y padding and
offer excellent lateral support. The back ­
rest shell is finished in Silver Grey.
Sports bucket seats.*
Available as an option are light weight
racing seats with folding backrest,
integrated thorax airbag and manual
fore/aft adjustment for driver and
passenger.
The carbon surface finish conceals
a seat shell in glass ­/carbon ­fibre
reinforced plastic. The backrest pivots
are positioned high in the side bolsters to
provide excellent lateral support to the
pelvic region. The seats are upholstered
in black leather as standard with seat
centres finished in Alcantara. The ‘GT3’
logo is embroidered on the headrests.
Adaptive Sports seats Plus.
Available on request, adaptive Sports
seats Plus blend sport with comfort and
are suitable for everyday driving or the
racetrack. They feature side bolsters
in leather, seat centres in black Alcantara
and an embroidered ‘GT3’ logo on the
headrests. Of fering 18 ­way electric
adjustment, the seats can be optimally
adapted to meet your needs in terms of
seat height, squab and backrest angle,
seat depth, fore/aft adjustment and four ­
way lumbar support. The side bolsters on
the seat surface and backrest can be
individually adjusted for precision lateral
support on winding roads and added
comfort on long journeys.

Environment.
We’ve already spoken about our contribu­
tion to motorsport. To be more precise,
about our responsibility for the future of
motorsport. We meet this responsibility
with intelligent technology, unconven ­
tional ideas and optimum performance.
Our approach to environmental protec ­
tion is no different. In an era of intensify ­
ing debate about global climate change
and CO
2 emissions, every automotive
manufacturer is asking what it has to
offer right now. Our answer has long
been the same: high power output
combined with high efficiency.
Porsche has managed to reduce fuel
consumption significantly across all
model ranges compared with the respec ­
tive previous model even though perfor ­
mance has been increased. This is made
possible by an efficient drive concept,
lightweight construction, optimised
aerodynamics and low rolling resistance.
The environmental management team
at the Porsche Development Centre in
Weissach aims to demonstrate a high
level of environmental responsibility. Here, technological developments are
carried out with environmental protection
in mind. The goal is to enhance perfor
­
mance – but preferably not at the expense
of the environment.
Fuel economy and recycling.
Intelligent lightweight construction has
been part of Porsche DNA since 1948 –
for both technological and ecological
reasons. And, of course, with competitive
advantages in mind. In motorsport, weight
is increasingly the number one factor
of success. Lightweight construction is
therefore the basis for low consumption
The true challenge:
not merely getting faster, but better.
values combined with outstanding
performance.
On the technical side, various compo ­
nents are made with a high proportion
of aluminium, magnesium, plastics and
super ­high ­strength sheet steel. The
materials used have been selected for
their abilit y to withstand load, yet they
are considerably lighter overall than
conventional steel.
