Standard on all new 911 Turbo models,
the Sport but ton enables you to select
a suspension setup to emphasize either
comfort or sport y performance. At
the push of a but ton, the electronic
engine management system switches
the engine mapping to offer an even
sharper response. In conjunction with
the Sport Chrono Package (standard
in the 911 Turbo S and the new
911 Turbo S Cabriolet), the overboost
function is then active and the dynamic
engine mounts become much firmer.
In Sport mode, PDK ensures that
upshifts take place at higher engine
speeds and downshifts happen sooner.
Coasting mode and the Auto Start
Stop function are deactivated.
Sport Chrono Package Including
Dynamic Engine Mounts
The Sport Chrono Package including
dynamic engine mounts is standard in
the 911 Turbo S models and available
as an option for the new 911 Turbo. This
integrated system provides simultaneous
enhancement for the chassis,
including rear-axle steering, engine,
transmission, and aerodynamics.
The main features include a digital
and analog stopwatch mounted on the
dashboard, a performance display in the
Porsche Communication Management
(PCM) system, the Sport Plus but ton,
and the overboost function.
Activate Sport Plus mode and here’s what
happens: Porsche Active Suspension
Management (PASM), the electronic
suspension management, becomes more responsive. PASM and Porsche Dynamic
Chassis Control (PDCC)—standard in the
new 911 Turbo S—switch to Sport Plus
mode for a firmer suspension set ting,
more direct steering while cornering, and
increased roll stabilization. The rear-axle
steering also reacts more directly—for
even more agile steering. As part of
Porsche Active Aerodynamics (PA A),
the automatic adjustment of the front
and rear spoilers is also impacted in
the performance setting in Sport Plus
mode. So you can make full use of the
performance potential of your 911 Turbo.
In Sport Plus mode, the trigger threshold
for PSM is raised. Agilit y is perceptibly
enhanced when braking for corners with
PSM, allowing sportier braking and exit
acceleration. For maximum dexterit y, PSM
can be set to standby while the car
i

s
still in Sport Plus mode. Although, for
safet y, it ’s still there in the background. With the Sport or Sport Plus but ton
active, under full acceleration, the
maximum boost pressure in the
lower and medium speed ranges
is now temporarily increased by
approximately
2 psi: the overboost.
Engine torque is also boosted
by 37 lb.-ft. for a short time—to
524 lb.-ft. in the 911 Turbo and the
911 Turbo Cabriolet. In the 911 Turbo S
models, it goes up to 553 lb.-ft.
The Sport Chrono Package has t wo
additional functions. The first is
Launch Control, which helps achieve
optimal acceleration from a standing
start. The second function is the
motorsport-derived gearshift strategy.
Using this, PDK optimizes shift
points to the shortest possible shift
times for maximum acceleration.

1 Dynamic engine mounts
With the dynamic engine mounts
that are part of the Sport Chrono
Package, Porsche engineers have
resolved this inherent conflict.
The mounts contain a fluid with
magnetic properties that interact Dynamic Engine Mounts
Engineers traditionally face a conflict
when designing the engine mounts
of a performance car. A hard engine
mounting delivers optimal performance
by offering a higher degree of handling precision. Soft engine mounts, on
the other hand, minimize oscillations
and vibrations. Comfort is improved
on uneven road surfaces, but at the
expense of razor-sharp performance.
with an electrically generated field.
Depending on the driving st yle and road
surface conditions, the electronically
controlled system automatically
adjusts the stiffness and damping
properties of the engine mounts.When the driving st yle is assertive, the
mounts become “hard,” and handling
is perceptibly more stable under load
change conditions and in fast corners.
Whenever a less assertive driving st yle
is adopted, the dynamic engine mounts “soften” to provide a more comfortable
feel. The dynamic mounts minimize the
oscillations and vibrations of the entire
drivetrain, especially the engine.
For the driver, the results are
tangible. A harder-edge handling
response when you demand it, a more
comfortable ride when you don’t.

2 Stabilizing effect of rear-axle steering
Power | Chassis
Rear-Axle Steering
Porsche engineers have always factored
in the positive effect of passive rear-
wheel steering—the slight articulation
of the rear wheels to “ toe in” or “ toe
out ” when cornering. Thanks to the new
rear-axle steering that ’s standard on all
new 911 Turbo models, that effect is no
longer passive. Two electromechanical
actuators located on the rear axle
steer the rear wheels of the new
911 Turbo models up to approximately
2.8 degrees in the same or opposite
direction as the steering angle on the
front axle, depending on speed. At speeds of up to 31 mph, 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, steering into corners
becomes much more dynamic, and
parking is noticeably easier.
At speeds above 50 mph, the system
steers the rear wheels in the same
direction as that of the front wheels.
The effect is a virtual extension of
the wheelbase for increased stability
during high-speed maneuvers—a
cruising-speed lane change on
the interstate, for example.Bet ween 31 and 50 mph, the
steering direction is constantly
changing, depending on the driving
conditions. Thanks to the excellent
stabilizing properties of rear-axle
steering, it has also been possible
to make the steering ratio on the
front axle more direct around the
central position. The advantage is
greater agilit y at higher speeds.
There is no contradiction between
stability and agility, performance,
and everyday practicalit y. The new
rear-axle steering results in greater
maneuverability in day-to-day
driving—and a clearly noticeable
increase in maximum performance.

Responsibility.
With great power comes great responsibility. To yourself, and to your
passengers. To those who share the road. To future generations and the
environment. At Porsche, we believe the actions we take must reflect
those responsibilities. And that our cars must turn engineering
challenges into opportunities, so Porsche and Porsche drivers can
contribute to a safer, more sustainable world.

Responsibility | Brakes
1 Standard brakes in the 911 Turbo
Why has Porsche always viewed braking
performance with the same enthusiasm
we share for our engines and chassis?
Perhaps it is because we think of braking
as negative acceleration. For us, braking
response and the stopping distances
achieved by the new 911 Turbo models
should be every bit as breathtaking as
our throt tle response and acceleration
times. A Porsche 911 Turbo model’s
goal is nothing less than to be the
new reference point for sports car
braking. The braking performance must
provide the driver ample reassurance
that when speed needs to be shed,
the brakes will respond accordingly. In the new 911 Turbo and the new
911 Turbo Cabriolet, the brake
specification is suited to the demands
of high performance. The brake disc
diameter is 380 mm front and rear.
Grabbing hold of the front discs are
powerful 6-piston, aluminum monobloc
fixed calipers finished in red. At the
rear, 4-piston, aluminum monobloc fixed
calipers press the pads to the disc.
The brake calipers have an enclosed
monobloc construction. This makes them
tougher but lighter and enables a more
rapid response and release of the brake,
even under extreme loads. The pedal
travel is short and the biting point precise. The brake discs are cross-drilled for
better performance in wet conditions.
Other benefits of the braking system
include the Anti-lock Brake System
(ABS), designed to minimize brake fade
and keep braking response constant.
Pedal effort is reduced and braking
response improved by a tandem
vacuum brake booster. Brake-disc
cooling is optimized by air spoilers.
Electric Parking Brake
The electric parking brake, which you
can activate and deactivate manually,
releases automatically as you pull away.
A performance isn’t finished until it comes to a complete stop.
Brakes.
With the hill-hold function, you can pull
away without ever rolling back. The
system automatically detects when the
vehicle has come to a halt on an uphill
gradient, requiring intervention. PSM
then maintains the brake pressure at
all four wheels to prevent the vehicle
from moving in the opposite direction.

Body
The innovative bodyshell of the new
911 Turbo models fulfills t wo structural
design requirements: first, excellent
driving dynamics due to the body’s
extremely high rigidit y. Second, a
savings in vehicle weight, primarily due
to its intelligent lightweight construction.
To meet the second requirement, we
employed state-of-the-art techniques
for combining various materials in order
to utilize specific material properties
exactly where they are needed.
Take the bodyshell, for example. It uses
very thin—but extremely rigid—sheets
of steel. Aluminum and magnesium
were utilized extensively in areas
including the roof, underbody, doors,
engine compartment, and luggage compartment lids. Magnesium, which
is a particularly lightweight material,
was also selected for the cockpit
and center console support beam.
Reducing the overall weight—i.e.,
improving the power-to-weight ratio—
translates directly into the aim of
increasing performance, whether
that ’s measured by the acceleration,
steering, or braking. And it ’s measurable
another way, too: at the fuel pump.
Reduced fuel consumption.
For the driver, reducing the weight
of the 911 Turbo results in a high
level of comfort as well. Vibration-
damping characteristics are
excellent and, compared to the
previous model, torsional stiffness
has increased up to 25 percent to
create even sportier handling.
Airbags and the Po
rsche Side Impact
Protection (POSIP) System
The airbag technology in the new 911 Turbo
models provides full-size driver and front-
passenger airbags, which are inflated in t wo
stages depending on the severit y and t ype
of accident. In less serious accidents, the
airbags are only partially inflated to help
minimize discomfort to the occupants.
Another standard feature is the Porsche
Side Impact Protection (POSIP) system.
This system comprises side impact
protection elements in the doors and t wo
airbags on each side, an integral thorax
airbag located in each seat side bolster,
and a head airbag contained in each of
the door panels. Knee airbags are also
standard on all 911 Turbo models.
Rollover Protection in the
Cabriolet Models
Despite their light weight, the 911 Turbo
Cabriolet models have exemplary
torsional rigidit y and flexural strength.
Body flexing is minimal, especially when
compared with driving most other open-
top sports cars on uneven road surfaces.
In the event of a 911 Turbo Cabriolet
model rolling over, additional protection
is provided by a supplemental safet y
roll bar protection system that deploys
automatically. The two spring-loaded
rollover bars are located behind
the back seats. The rollover sensor
continuously monitors the car’s pitch
and roll, lateral and longitudinal
acceleration, and contact with the road.
In an emergency, it deploys the rollover
bars within a fraction of a second.

6768 Responsibility | Environment
Porsche has increased efficiency in all
of its current series while at the same
time increasing performance. This is
achieved by an efficient drive, thanks
to Direct Fuel Injection (DFI), Porsche
Doppelkupplung (PDK), Variable Turbine
Geometry (V TG) and VarioCam Plus,
intelligent lightweight construction, active
aerodynamics, and low rolling resistance. A high level of environmental
responsibilit y is ensured not least
by Porsche’s own environmental
management teams in Weissach. They
ensure that all developments take
account of environmental compatibility.
The objective is to achieve pure
performance, but not at the expense
of the environment. This also applies
to the new 911 Turbo models.
All automotive manufacturers look
to the future. After all, the life-span
of an automobile from inception to
the end of its functional life can span
decades or even longer. So what
the world needs in 15 to 20 years,
Porsche engineers must address now.
Our focus is always on this: ultimate
performance with ultimate efficiency.

Environment.
Exhaust Emissions Control
At Porsche, our cars have long
demonstrated that even high-performance
sports cars can achieve moderate fuel
consumption and exhaust emissions
values in their respective category. The new 911 Turbo is no exception. It
uses technologies such as Auto Start
Stop, thermal management, electrical
system recuperation, Direct Fuel Injection
(DFI), VarioCam Plus, and coasting
to help optimize fuel efficiency.And the cataly tic converters provide
efficient emissions control.
The stereo lambda sensor controls
and monitors each cylinder bank
separately. For each exhaust tract, oxygen sensors regulate the composition
of the exhaust gas, while another
lambda sensor on each cylinder bank
monitors pollutant conversion in the
respective catalytic converter.
