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.

GT racing.
‘Gran­Turismo’ or GT racing cars are
exclusively prepared for competition
use. However, regulations state that they
must be based on road ­legal cars, with
modifications restricted to a few specific
areas. In the early 1990s, Porsche was
the driving force behind the renaissance
of international GT motorsport. In the
meantime, Porsche has established suc ­
cessful collaborations with customer
teams. Porsche supplies the race ­ready
cars and supports private teams with
further development, technical services
and the provision of factory drivers.
Whether it ’s in the 24 Hours of Le Mans,
the ALMS, the International GT Open
or at national GT championships, Porsche
private teams are regular race and
championship winners.
GT3 Cup Challenges.
The gateway to semi ­professional motor ­
sport. Race locations include Australia,
Brazil, Central Europe, Great Britain,
Japan, Scandinavia, Switzerland, USA,
Canada and the Middle East. Races
are governed by the regulations of the
Porsche Carrera Cup Germany. The
prerequisite to participation is a national
licence.
Porsche Carrera Cups.
From the fastest one ­make championship
in Germany to the international top event.
The Porsche Carrera Cups play host in
many countries to first ­class motorsport
highlights, such as the German Touring
Car Masters (DTM) or, most recently, the
24 Hours Nürburgring. The tradition of
the Porsche Carrera Cup spans over 20 years. Since the first Porsche Carrera
Cup Germany was staged in 1990, a
further seven Porsche Carrera Cups have
become established in France, Great
Britain, Scandinavia, Italy, Japan, Asia
and Australia. Races are held on almost
every weekend of the motorsport season.
The passion to win fuels the fight for
ever y single millimetre: young upstarts
challenge old hands, amateurs compete
with professionals and rookies take on
experienced customer drivers.
Porsche Mobil 1 Supercup.
The pinnacle of the one
­make champion ­
ships. Since 1993, the Porsche Mobil 1
Supercup has been held as part of the
FIA Formula One World Championship –
and as the only Gran Turismo race series.
All cars are supported by professional racing teams, which use t wo to three
racing cars in the championship. The
events take place mainly as part of the
European Grand Prix, with a race dis
­
tance of approximately 70 kilometres.
The drivers, which include established
personalities alongside promising new
talent, give every thing they have from
start to finish. After all, another prize
might just be up for grabs: a career in
GT racing.

On the ecological side, all materials used
are meticulously selected. Each light­
weight material is easily recyclable
and all plastic components are labelled
to facilitate separation for recycling.
The
reduction in the number of plastic
variants helps to ensure more efficient
recycling. Recycled plastics are used
where they meet our exacting technical
requirements.
In short, the new 911 GT3 is around 95 %
recoverable. In addition, Porsche uses a
high proportion of environmentally friendly
water ­based paints. For us, environmental protection does not begin at the end of

a vehicle’s life. It starts at the planning
and development stage.
Emission control.
The new 911 GT3 meets the strict Euro 5
emission standard in the EU and LEV II
in the USA. Vehicles manufactured by
Porsche demonstrate that even high ­
performance sports cars can achieve
moderate emission values in their
respective category. This puts the new
911 GT3 among not only the most powerful sports cars of the future, but
also the cleanest.
This has been accomplished not least by
the t wo cataly tic converters and stereo
Lambda control circuits, which monitor
each cylinder bank separately. For each
exhaust tract, t wo Lambda sensors regu
­
late the composition of the exhaust gas.
Another Lambda sensor for each cylinder
bank monitors pollutant conversion in the
respective cataly tic converter.
Fuel.
All Porsche models – including the new
911 GT3 – are designed to operate on
fuels with an ethanol content of up to
10 %, e.g. ‘E10’. Ethanol has a positive
impact on the CO2 balance since the
plants grown for the production of
this biofuel also absorb CO
2 from the
atmosphere.
The release of hydrocarbons from the
fuel system has been minimised thanks
to the active carbon filter and the
multi ­layered material from which the
fuel tank is made. All fuel lines are
made from multi ­layered plastic, steel
or aluminium.
