2013 PORSCHE 911 GT3 torque

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.

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.

VarioCam.
The upgraded VarioCam system is an
engine timing concept that distinguishes
bet ween various engine speeds and
load states so that timing can be adapted
to suit the current power demand. It
regulates not only the adjustment of the
intake camshafts but also the exhaust
camshafts in order to deliver increased
power and torque.
Adjustments are controlled imperceptibly
by the new electronic engine manage ­
ment. The results are extremely smooth
running, better fuel economy, low emis ­
sions and, above all, high power and
torque across the entire engine speed
range.
Dry-sump lubrication.
The engine oil supply is vital at the limits
of sporty performance, especially
in the presence of the powerful lateral
and longitudinal forces that can be
experienced on the racetrack.
Two oil scavenge pumps per cylinder
head and t wo scavenge pumps in the
crankcase return the engine oil quickly
and efficiently to the external tank.
In conjunction with the electronically
controlled oil pressure pump, this means
that the engine has a reliable supply
of oil to the crankshaft drive and both
cylinder banks. The new 911
GT3 is factory ­filled with
Mobil 1 fully synthetic high ­performance
oil. The excellent lubrication properties of this oil ensure a reliable cold start, even
at ver y low temperatures, and contribute
not least to the durabilit y of the engine.

Intake manifold.
In interaction with the sports exhaust
system, the plastic variable intake manifold
helps to ensure efficient gas cycles and
high throughput.
To guarantee high torque and power
across a broad engine speed range,
the conventional distributor pipe in the
new 911 GT3 is supplemented by a
resonance pipe with resonance flap. This is opened or closed depending on
the engine speed. For optimum cylinder
charge.
This results in an impressive torque
curve, a high maximum torque and
ultimate power output across a broad
engine speed range.
Sports exhaust system.
The sports exhaust system of the new
911
GT3 has t wo front silencers, t wo
catalytic converters and one rear silencer,
which discharges into the central twin ­tract
tailpipes. The large volume of the exhaust
system reduces exhaust backpressure and
thus increases power output.
The t wo Lambda sensors of the stereo
Lambda control circuitry regulate the composition of the exhaust gas separately
in each exhaust tract, while another

pair monitors pollutant conversion in the
respective cataly tic converters.

Porsche Stability Management (PSM).
PSM is an automatic control system for
providing stabilit y at the limits of dyn­
amic driving performance. In addition to
the anti ­lock braking system, it includes
Electronic Stability Control (ESC) and
Traction Control (TC).
Sensors continuously monitor the direc ­
tion, speed, yaw velocit y and lateral
acceleration of the car. Using this infor ­
mation, PSM is able to calculate the
actual direction of travel at any given
moment. If the car begins to oversteer or
understeer, PSM applies selective braking
on individual wheels to restore stabilit y. What ’s special about PSM in the new
911
GT3? The systems intervene at the
limits of dynamic driving performance
with exceptional sensitivit y and precision.
In addition, the systems can be complete ­
ly deactivated in t wo stages for deliber ­
ately sporty handling.

Porsche Torque Vectoring Plus
(PTV Plus).
Porsche Torque Vectoring Plus is fit ted as
standard and has been specially adapted
to the new 911 GT3. It operates in con ­
junction with an electronically regulated
and fully variable rear differential lock.
Numerous driving parameter inputs are the basis for the system’s active control
outputs. The results are perceptible, par
­
ticularly at the limits of dynamic perfor ­
mance: greater traction, increased lateral
dynamics and a significant improvement
in driving stabilit y under the effects of
load changes in corners and when the car
changes lane. On surfaces with less grip,
such as in the wet, the system strategically
brakes the right or left rear wheel. This
means that, whenever the car enters a
corner, brake pressure is applied to the
inside rear wheel. Consequently, a greater
amount of drive force is distributed to the
outside rear wheel. This improves steering
behaviour and increases agility. In combination, both aspects of PT V Plus
offer tangible benefits, giving you
unrivalled pleasure at every t wist and
turn. It ’s just as well there happens

to be so many waiting on the racetrack.
