Introducing the New 911.
The New 911 | Introduction
Platzhalter 911 Carrera und 911 Carrera S
The Porsche 911 has always been
a study in contrasts. At its 1963
debut, it did more than delight
enthusiasts with its race-bred
technology—it astonished them with
its suitability for everyday driving.
Here was a car replete with track-
tested innovations—a six-cylinder boxer
engine, fully independent suspension,
and four-wheel disc brakes—that
offered a spacious cockpit, tractable
road manners, and ample room for
groceries and luggage. With this rare
balance, the new Porsche ushered
in a golden age of sports cars.
5 6
A New Golden Age
In the new 911, Porsche applies this
singular balance to the priorities of a new
era. Tradition dictates that a new 911 must
outperform its predecessors in driving
dynamics—no small feat considering the
30,000 racing victories won by the 911
over generations. At the same time, it must
prove its relevance to a new generation.
So the engineers at Weissach did more
than invest the next 911 with breathtaking
performance. They balanced it with
intelligent solutions for the 21st century:
engines that were more efficient and
generated greater power; safety systems
so advanced, they enhanced rather than
intruded on the driving experience; and
information and entertainment systems,
seamlessly integrated into the most
rewarding 911 interior yet created.
Icon and Iconoclast
Call it the 911 paradox: For nearly
50 years, no car has remained so
instantly recognizable; yet no car has
undergone such constant change.
Porsche’s most legendary model has
remained at the vanguard of sports
car performance, not because it is an
icon, but because it is an iconoclast.
The new 911 exemplifies this
apparent contradiction. Its identity
is unmistakable. Yet 90 percent of
its components are either new or
fundamentally revised. Its timeless
shape incorporates significant
dimensional changes that include a
longer wheelbase, wider front track,
lower roofline, and on the Cabriolet a
new top. The body is a composite of
aluminum and various types of steels
that increase torsional rigidity up to
25 percent over its predecessor.
The engines have been developed
with new, efficiency-enhancing
technologies—such as Auto Start Stop,
thermal management, and electrical
system recuperation—that reduce
fuel consumption while optimizing
performance. Porsche’s first-ever seven-
speed manual transmission allows for
precise control of engine power while
also improving fuel efficiency. The
optional 7-speed Porsche Doppelkupplung
(PDK) transmission provides even
greater fuel efficiency with its new
coasting feature, not to mention the
thrill of lightning-quick gearshifts.
Tradition Without Bounds
If there is one tradition we hold sacred,
it is our commitment to innovation. If
there is one car that crystallizes our
latest thinking, it is the 911. The ideals
embodied in every generation of this
legendary car—race-bred performance,
everyday practicality—have once
again been taken to the next level.

Exterior design.
The New 911 | Design
Not a single surface remains unaltered.
Yet, somehow, every enthusiast knows
it at a glance. What makes this new
design so emphatically a 911?
It’s what you see—and what you don’t.
In this and every 911, not a single line
is wasted. By shunning the superfluous,
its form invites the eye to slip over its
surface, just as the air slips over its
contours with a drag coefficient of just
0.29 for the Coupes and 0.30 for the
Cabriolets. It is by following function,
rather than fashion, that this legendary
sports car retains its timeless appeal.
In the new 911, its pure form also
speaks volumes about the car’s
balanced temperament, manifesting
7 8
an unprecedented balance of
athleticism and refinement.
New Dimensions
The tapering roofline has been lowered,
exposing less surface to the air. The
front track has been widened by 1.8
inches (46 mm) on the 911 Carrera
and just over 2 inches (52 mm) on the
911 Carrera S for improved cornering
stability. Together, these changes
accentuate the first impression
of sportiness and elegance when
viewing the car from the front.
A Distinctive Front View
New Bi-Xenon™ headlights are standard.
Their classic oval-shaped surrounds
reveal their technically impressive inner
workings. The Porsche Dynamic Light
System (PDLS), with dynamic cornering
lights and speed-sensitive headlight
range control, is available as an option.
The new direction indicators, daytime
running lights, and side marker lights
are all LEDs and are integrated into the
separate front-light units. Their slim,
linear design contrasts with that of the
rounded headlights. Together with the
two integral air intakes, they make the
front of the new 911 unmistakable.
Balance in Profile
Circling around to the side of the new
911, one can see that the exterior
mirrors are now mounted directly on
the doors. This results in improved
aerodynamics. A firmly planted stance is
also apparent—the result of a 3.9-inch
(100mm) longer wheelbase, and shorter
overhangs at both front and rear. These
alterations do more than please the
eye—they contribute to driving stability
while offering greater interior room.
New 19-inch and 20-inch wheels
are standard equipment on the new
911 Carrera and 911 Carrera S,
respectively. One inch larger than those
of the previous model, they enhance the
sporty presence of the new 911, and
their increased rolling circumference
improves both comfort and performance.
Increased agility is just one of the
results of all these refinements.
Lasting Impression
Drivers are accustomed to seeing
the 911 from behind, thanks to its
effortless passing ability. From this
perspective, the 911 makes a concise
statement of power in perfect balance.
This effect is accentuated by a new,
crisp trailing edge that travels without
interruption over the LED taillights and
across the rear deck. The wide track
is also accentuated by a defined edge
traveling over the repositioned rear
reflectors. Stainless steel tailpipes
feature a new ovoid cross section on the
911 Carrera, becoming the horizontal
contours above. On the 911 Carrera S,
twin tailpipes are fitted on both sides. In
all new 911 models, the characteristic
extendable rear spoiler has been
widened to increase downforce.
Finally, the Porsche badge returns
with fresh prominence, befitting the
place of the 911 as the most enduring
legend in the Porsche stable.
Comfort and performance in harmony.

The 911 interior.
The New 911 | Design
Since the introduction of that first
Porsche in 1948, we have demonstrated
that comfort is not only compatible with
driving performance—it is essential.
Harmony between man and machine is
especially evident in the new 911. The
layout of the instruments and controls,
the logic of their operation, even the
tactile sensation engineered into every
interior surface, are designed to relax
the senses while providing all the
information needed in a new generation
of highly advanced sports car.
9 10
Classic yet Modern
The classic five-gauge layout is still the
best way to provide essential driver
information. In keeping with Porsche
tradition, the tachometer is located
at the center of the display, easily
glimpsed through the sport steering
wheel. The refined steering wheel
features a high-grip smooth-leather rim.
Long-legged drivers now have even
more room to stretch out, thanks to
an additional inch (25 mm) of legroom.
Fitted as standard, the 911 has refined
sport seats that combine even greater
comfort with racing-style support and
now feature four-way power adjustment.
Advanced Technology
The new center console puts logically
organized controls at the fingertips of
the driver or front-seat passenger and
includes a high-resolution, 4.6-inch
full VGA TFT color display, for viewing
onboard computer, audio system,
or navigation information. The new
automatic climate control with zonal
temperature controls for the driver
and front passenger is standard.
Personalization
In the new 911, the traditional choice
of interior options includes innovative
additions. A new lighting design package
allows you to customize the level of
illumination in the footwells, ignition
lock, storage compartments, rear
compartment, and overhead console.
An extensive selection of interior colors
and materials—such as Carbon Fiber,
leather, wood, or Aluminum—allows
a high degree of personalization.
The acoustic sensations of driving
a 911 extend beyond the music of
the engine note. A nine-speaker,
235- watt audio system is standard,
and can be combined with the
optional HD Radio receiver or Bose
Surround Sound System. For the
ultimate sound experience, Porsche
offers the optional Burmester®
High-End Surround Sound System.

The New 911 | Engineering
Through its history, the 911 has served
as a summation of every thing we know.
Today, concepts proven over a half
century are enriched by groundbreaking
innovations, ideas that not only make
for a better sports car, but something
even more impressive: a bet ter 911.
Greater Power and Efficiency
The new engines follow the time-
honored 911 design: six horizontally
opposed cylinders provide a lower
center of gravity than do more
common configurations. Output has
been increased to 350 horsepower in
the new 911 Carrera models and 400
horsepower in the 911 Carrera S models.
*Please refer to 2012 U.S. EPA Fuel Economy Estimates on page 94.
11 12
Both models are equipped with Direct
Fuel Injection (DFI) and VarioCam Plus
for increased power and reduced fuel
consumption.* This power is transmitted
to the wheels by the introduction
of our first seven-speed manual
gearbox or, optionally, the Porsche
Doppelkupplung (PDK) transmission,
which offers gear changes with virtually
no interruption in the flow of power.
Despite this increased output, fuel
consumption efficiencies are the result
of several innovative technologies
that optimize engine performance
and reduce the load that’s placed on
the engine by peripheral systems.
New Composite Architecture
The unibody employs a combination
of aluminum and steel to reduce
weight while improving the already
remarkable rigidity of the 911 chassis.
This new architecture helps achieve an
impressive power-to-weight ratio of 7.6
lb./hp for the 911 Carrera S Coupe.
The chassis is also packed with forward-
looking technology. Now standard in
the 911 Carrera S models, Porsche
Torque Vectoring (PTV) increases
dynamic performance and control. Newly
available as an option for the S models,
Porsche Dynamic Chassis Control (PDCC)
improves dynamic performance further
still. Dynamic engine mounts, included
as part of the optional Sport Chrono
Package, are now available for the
911 Carrera models for the first time.
These provide perceptibly more stable
handling during aggressive cornering.
Through these advances, the new 911
satisfies the enthusiast’s desire for
even greater performance and the
world’s need for greater ef ficiency.
Passion meets practicality.

The new 911 Carrera.
The New 911 | The 911 Carrera
The new 911 Carrera was created to
redefine the everyday driving experience,
delivering exhilarating performance with
surprising practicality. Although its engine
displacement has been reduced to 3.4
liters, it generates more power and faster
acceleration than its celebrated 3.6-liter
predecessor, sprinting from 0–60 mph
in just 4.6 seconds—4.2 seconds when
equipped with the optional Porsche
Doppelkupplung (PDK) transmission
and the Sport Chrono Package.
Advanced Powertrain
How did Porsche engineers balance
the sensible with the sensational?
The new thermal management
technology manipulates heat flow
13 14
to bring engine and transmission to
optimal operation temperatures faster,
reducing fuel consumption. Electrical
system recuperation reduces the
alternator’s draw on engine power,
freeing it for pure exhilaration.
Other benefits come from a choice of
two advanced transmissions, including
a seven-speed manual gearbox. The
first six forward gears have a sport
ratio, while the seventh has a long
ratio that reduces fuel consumption
and engine noise at highway cruising
speeds. The optional PDK also employs
seven forward gears with a long-
ratio top gear for efficient cruising. A
new addition to PDK is the ingenious
coasting function, which eliminates
engine braking in certain conditions
for even greater fuel efficiency.
The Sport button, which is fitted as
standard in the 911 Carrera, makes
it possible to select an even more
responsive engine performance program.
In vehicles equipped with PDK, the Sport
button also selects more aggressive
shift points when in automatic mode.
Sportiness and Safety
The new 911 Carrera is fitted as
standard with 19-inch wheels,
which improve driving stability and
performance while enhancing the car’s
visual presence. Powerful braking is
provided by four-piston, aluminum
monobloc brakes with black calipers,
and optimized with ABS (Anti-lock
Brake System) and standard Porsche
Stability Management (PSM). In addition
to helping provide stabilty, PSM
improves braking response and braking
power in emergency conditions.
With its potent and efficient powertrain,
luxurious and purposeful interior,
and outstanding performance and
safety, the 911 Carrera delivers a
rare combination of driving passion
and everyday practicality.
The superlative form of Carrera.

The new 911 Carrera S.
The New 911 | The 911 Carrera S
One let ter can say quite a lot. For
Porsche, “S” designates the superlative
form of the 911 Carrera. In the new
Carrera S, track-ready performance
is taken to a new level through a host
of engine and chassis advancements.
Impressively, its improved power and
agility coexist with fuel efficiency.
400 Horsepower with Efficiency
The new Carrera S achieves 400
horsepower from a 3.8-liter boxer
engine. The engine benefits greatly
from Porsche’s ongoing development
of VarioCam Plus, which optimizes
power and torque at all engine
speeds, and Direct Fuel Injection
15 16
(DFI), which improves combustion.
A suite of innovations—including the
standard Auto Start Stop function, thermal
management, and electrical system
recuperation—provides even greater fuel
efficiency while freeing more power.
Commanding Acceleration
The new Carrera S accelerates from
0–60 mph in a breathtaking 4.3 seconds,
and achieves a top track speed of 188
mph. When equipped with the optional
PDK and Sport Chrono Package, it
sprints from 0–60 in just 3.9 seconds
.
Other Carrera S Sensations
Outstanding acceleration is just one
sensation that sets the Carrera S apart.
Visually, its standard 20-inch wheels make
a bold statement while also improving
stability. The resonant engine sound
is enhanced by two matched pairs of
brushed stainless steel tailpipes.
One also feels the superlative damping
control of Porsche Active Suspension
Management (PASM) and the increased
agility and steering precision of
Porsche Torque Vectoring (PTV),
both standard in the Carrera S.
Shorter Braking Distance
For the first time, the new 911 Carrera S
features front brakes with six (rather
than four) pistons in a solid monobloc
red caliper, resulting in even shorter
braking distance.
The 911 Carrera S has always been a bold
expression of the 911 Carrera character.
In the new Carrera S, the performance
envelope has expanded to embrace
greater efficiency for a new century.

The 911 engines.
The New 911 | Engine
Efficiency is not only compatible with
performance—it is essential. From the
“Giant Killer” Porsche 550 of the late
1950s to the hybrid-powered 911 GT3 R
of the 2010s, our racing history is
replete with examples of Porsche
engineers squeezing more performance
from every drop of fuel and every
cubic centimeter of displacement.
The engines powering the new 911
models bring this discipline once again
to daily driving—not just reducing fuel
consumption, but delivering higher
output across the power band.
Building on Excellence
Our engineers analyzed an extensive
series of engine components to
discover the best solutions for improved
efficiency. This effort uncovered new
possibilities, including the rapid heating
of the engine and gearbox to reach
optimal efficiency sooner after start-
up, tuning of air induction to optimize
flow at all engine speeds, and Direct
Fuel Injection (DFI) refinements to
enhance combustion efficiency.
The New 3.4-Liter Engine
Each of the new engines begins with
a strong foundation, retaining a light-
alloy construction to reduce weight
while assuring structural rigidity for

Auto Start Stop Function
The Auto Start Stop function is standard
in the new 911 models. In the 911
equipped with manual transmission, the
engine switches off automatically when
you come to a stop, select Neutral,
and release the clutch pedal. In cars
equipped with the optional Porsche
Doppelkupplung (PDK) transmission,
pedal. All audio and communication
systems remain switched on and the
climate control continues to maintain
your selected temperature. The only
differences you will notice are the
silence at the rear and the fuel savings.
As soon as you engage the clutch
or release the brake, the engine will
restart instantly and smoothly.
The Auto Start Stop function may remain
inactive under certain circumstances—
for example, during extreme outside
temperatures, if the battery charge is
low, or if the Sport button is selected.
It is also possible to deactivate the
function manually using a separate
button on the center console.
Thermal Management
The new thermal management system
regulates the temperature in the engine
and gearbox through the intelligent
manipulation of heat flow. In this way,
the engine and gearbox reach their
optimal operating temperature sooner,
reducing fuel consumption through
increased combustion efficiency
and lubrication performance.
Electrical System Recuperation
The new 911 models are also equipped
as standard with fuel-saving electrical
system recuperation technology. The
vehicle battery is recharged by the
alternator, predominantly under
braking. Under acceleration on the
other hand, the power draw of the
alternator is limited to increase the
engine output available for driving.
The electrical systems are supplied
by the electrical energy stored
during the recharging process.

Advancing the art of internal combustion.
Efficiencies for the future.
The recipe for internal combustion—
air, fuel, spark—has never changed. But
through over 60 years of engineering
advancement, Porsche has turned this
simple recipe into a work of art by fine-
tuning the precise timing, volume, and
movement of these ingredients to suit
the full range of driving demands.
Direct Fuel Injection (DFI)
DFI delivers fuel directly into the
combustion chamber. Injected under
pressure, the atomized fuel has a cooling
effect that allows for a higher compression
ratio, resulting in greater power output.
In the new 911 engines, the spray
and cone angles of the new multi-hole
injectors have been further optimized for
torque, power output, fuel consumption,
emissions, and combustion efficiency.
Depending on conditions, DFI performs
up to three injection pulses per
combustion cycle. These multiple pulses
generate greater torque in the upper
load range, and faster heating of the
catalytic converters after a cold start.
VarioCam Plus
The VarioCam Plus system adjusts
valve timing and valve lift on the inlet
side to provide optimal performance
under different driving conditions. The
system differentiates between driver
inputs that typify normal, everyday
motoring and those that demand
maximum engine response. Based on
these factors, it adapts valve operation
to the prevailing conditions. This
results in smooth running, responsive
acceleration, extraordinary power on
demand, and efficient fuel consumption.
Integrated Dry-Sump Lubrication
Integrated dry-sump lubrication ensures
steady lubrication, even under severe
and prolonged cornering, braking, and
accelerating forces. An electronically
controlled oil pump supplies the
lubricating points inside the engine
as required. In this way, the engine
operates at peak efficiency even under
extreme high-performance driving
conditions. The oil tank is located in
the engine, thereby eliminating the
need for an external oil tank, which
saves both space and weight.
Air-Intake System
This system adjusts the volume of air
entering the engine to suit changes in
engine speed. It does so by cleverly fine-
tuning the air’s vibration as it passes
through the intake manifold. Benefits
include higher torque at low engine
speeds, a flatter torque curve, and a
sporty sound at higher revolutions. The
Carrera S operates a two-stage system.
The entire intake system is made from a
durable, lightweight synthetic material.
Exhaust System
The exhaust system of the new 911
models has been completely redesigned.
The stainless steel system comprises
two fully independent exhaust tracts.
Each is served by its own cataly tic
converter, engineered to heat up rapidly
for effective emissions reduction. A
twin-tube sport exhaust is available as
an option. With the touch of a button, it
produces an exhaust note with an even
more aggressive sporting character.
