Recuperation.
The electronic engine management
unit in the new Panamera S Hybrid
controls the braking process so
that, on activation of the brake
pedal, as much applied energy as
possible can be recovered via the
generator mode of the electric motor and returned to the 288-volt
nickel-metal hydride bat tery. This
process is known as recuperation.
Display concept.
The E-Power meter in the dashboard
s
hows the recuperation power and
drive power of the electric motor and the TFT colour display gives
real time information on the
energy flow.
The optional Porsche Communica-
tion Management (PCM) shows a
detailed diagram of the vehicle
with energy flow and statistics on
the amount of driving without the
combustion engine.
Additional electrical functions.
The systems which are normally
dependent on the drive power of
the combustion engine, such as
climate control, power steering
and braking, are powered
electrically in the new Panamera S
Hybrid. The functions remain
available for purely electric driving or when coasting with the combus-
tion engine switched of f.
Direct fuel injection (DFI).
With DFI, the fuel is injected directly
into the combustion chamber at
up
to 120 bar pressure with milli-
second
precision via electromag-
netically activated injector valves.
The spray and cone angles of the
injection are optimised for torque,
power, fuel consumption and emis-
sions by enabling a homogeneous
distribution of the air/fuel mixture
and, therefore, effective combus-
tion. DFI improves the internal
cooling of the combustion chamber
by forming the mixture directly
in the cylinder. The resulting higher
compression ratio delivers more
output at the same time as
enhanced engine efficiency, thus
helping to protect the environment.
Variable camshaft control.
In the V6 combustion engine of
the new Panamera S Hybrid, fully
variable camshaft control is used to
adjust the intake camshaf t timing.
This is ef fectively controlled by the
electronic engine management
system. The result is maximum
output and high torque – even at
low engine speeds – and above
all, reduced fuel consumption and
emissions.
In summary, thanks to Porsche
Intelligent Performance, the new
Panamera S Hybrid delivers the
performance of a sportscar, along
with the low fuel consumption and
emission values of a hybrid vehicle.

Porsche Stability Management
(PSM).
PSM is an automatic control system
for stabilit y even at the limits of
dynamic driving performance.
Sensors continuously monitor the
direction, speed, yaw velocit y and
lateral acceleration of the vehicle.
PSM uses these values to calculate
the actual direction of travel. If
the car begins to oversteer or
understeer, PSM applies selective
braking on individual wheels to
restore stability.
When accelerating on low-grip
road surfaces, PSM increases
traction using the automatic brake
dif ferential (ABD) and anti-slip
regulation (ASR). For a more active
driving experience, PSM can be
switched off but it remains active
in the background.
Two further functions of PSM
include precharging of the braking
system, to achieve maximum
braking force earlier, and brake
assist for maximum deceleration
in an emergency.
SPORT button.
The standard SPORT but ton is
used to switch bet ween comfort
and sport y setups. At the push of
a but ton, the electronic engine
management system makes the
engine more responsive so that the
engine dynamics become more
direct. The 8-speed Tiptronic S
gearbox shifts up later – and down
earlier. Porsche Active Suspension
Management (PASM) is set to
SPORT mode for harder damping
and more direct steering and,
therefore, greater agilit y on cor-
nering.
Even in SPORT mode, all driving
modes specific to the hybrid
engine are retained, such as elec-
tric driving or recuperation.
E-Power supports the combustion
engine at just 80 % accelerator
pedal position, instead of only on
kick-down as usual.
Sport Chrono Package Plus.
Sport Chrono Package Plus is
available as an option for the
Panamera S Hybrid (only in
conjunction with Porsche Commu-
nication Management – PCM) for an
even sportier vehicle setup.
This includes a digital and analogue
stopwatch, the SPORT PLUS button
and a performance display in the
PCM for lap times. When the
SPORT PLUS but ton in the centre
console activates SPORT PLUS
mode, the engine management
system makes the engine more
responsive, as in SPORT mode.
Porsche Active Suspension Manage-
ment (PASM) is set to SPORT PLUS
mode for harder damping. The
adaptive pneumatic suspension
lowers the vehicle and switches
to a harder spring rate.
Porsche Stabilit y Management
(PSM) intervenes later in SPORT
PLUS mode – for increased
longitudinal and lateral dynamics.
Agilit y is enhanced when braking
for corners with PSM enabling
greater manoeuvrabilit y under
braking and exit acceleration,
particularly at low speeds. SPORT PLUS mode of fers even
more agilit y when PSM is switched
off. However, for safet y, it is set to
intervene automatically only when
ABS assistance is required on both
of the front wheels.
A key component of the Sport
Chrono Package Plus is the
stopwatch mounted on the dash-
board. It displays, stores and
analyses lap times and times for alternative routes and Porsche
Communication Management
(PCM) is extended to include the
performance display.

The new Panamera S Hybrid | Balance
Brakes.
The braking system of the
Panamera S Hybrid is equipped
with six-piston aluminium mono-
bloc fixed calipers at the front and
four-piston aluminium monobloc
fixed calipers at the rear, with
brake disc diameters of 360 mm
and 330 mm, respectively. The
discs are internally vented for rapid
heat dispersal.
The manually activated electric
parking brake releases automati-
cally on pulling away. Using the
hill-hold function you can pull away without rolling back on the flat or
on an incline. Via PSM, even on a
hill, the system automatically main-
tains the brake pressure on all four
wheels for a brief period, and pre-
vents the vehicle from rolling away
in the opposite direction.
Porsche Ceramic Composite
Brake (PCCB).
The racetrack tested Porsche
Ceramic Composite Brake (PCCB)
is available as an option for 19-inch
wheels or larger. The cross-drilled
ceramic brake discs have a dia-
meter of 390 mm at the front and
350 mm at the rear. The key advantage of PCCB is its
total weight saving. Its brake discs
are approximately 50 % lighter than
standard brake discs of similar
design and size. As well as enhanc-
ing performance and fuel economy,
this large reduction in both
un sprung and rotating masses
ensures bet ter handling and road
holding, improved agilit y and
increased comfort, especially on
uneven road surfaces.
Environment.
Over the last 15 years, Porsche
has reduced the CO
2 emissions of
its vehicles by an average of 1.7 %*
per year. In relation to engine
power, Porsche is already among
those vehicle manufacturers with
the lowest CO
2 emissions – thanks
to efficient engine technology,
lightweight construction, optimised
aerodynamics and low rolling
resistance. Porsche proves that even high per-
formance sportscars can achieve
moderate consumption and emis-
sion values for their categories.
The Panamera S Hybrid meets the
requirements of the Euro 5 emis-
sions standards in Europe and
ULEV regulations in the USA.
How? By ef ficient use of fuel with
technologies such as parallel full
hybrid drive, Direct fuel injection
(DFI) and recuperation, when the bat tery is charged mainly during
the braking phases.
In addition, the body of the
Panamera S Hybrid consists of
around 23 % light weight alloy.
For example, the bonnet, doors,
front wings and tailgate are made
of aluminium which saves weight
and fuel.

CDR-31 audio system.
The CDR-31 audio system has a
7-inch colour touchscreen for
intuitive control of key functions
and menus. The integral CD radio,
including FM dual tuner and RDS
diversit y, 30 memory presets,
dynamic autostore and speed-
sensitive volume control, com-
prises a sound system with 10 loudspeakers and a total audio
output of 100 Wat ts. An optional
integrated six-disc CD/DVD auto -
changer is available. As an option,
CDR-31 can be combined with the
BOSE
® Surround Sound System.
Porsche Communication
Management (PCM) with
navigation module.
Porsche Communication Manage-
ment (PCM) is available as an
option on the new Panamera S
Hybrid. PCM is the central
information and communication
system. Powerful, versatile –
yet easy to operate.
The focal point is the 7-inch high-
resolution touchscreen. A maxi-
mum of five entries per page
ensures clarit y of presentation. In
specific situations, a help function
is displayed at the bot tom of the
screen.
A central function of the PCM in
the Panamera S Hybrid is the
graphic display of the hybrid drive
with its energy flow diagram, e. g.
for E-driving, E-Power, recuperation
or coasting. A statistical display
also shows the proportion of
driving that is emission-free, in
relation to the total driving time.
The radio has 42 memory presets,
an FM dual tuner with RDS diversit y which constantly scans in the back-
ground for the best signal, and a
dynamic autostore.
The CD/DVD drive plays CDs and
audio DVDs and is MP3-compatible.
Audio playback of video DVDs is
also supported. A six-disc CD/DVD
autochanger integrated in the PCM
is available as an option.
An optional universal audio interface
in the storage compartment of
the front centre console provides
a USB port for the connection and
charging of various iPod
® and
iPhone
® models, and for connect-
ing MP3 players or USB memory
sticks with MP3 music. It is oper-
ated
via the PCM, the optional
multifunction steering wheel or the
optional voice control. The USB port can also be used to download
the data on the electronic logbook.
The AUX interface is used to
connect an external audio source,
operated directly on the device
connected.
The navigation module with high-
speed hard drive, included with
PCM, gives you a choice bet ween
perspective or a t wo-dimensional
map view. You can also display
scenes and buildings in 3D in
some areas. The remaining route
is automatically adapted to the
maximum screen size. Split screen
mode enables you to view not only
the current map section but also
a list of symbols representing
your next driving manoeuvres.
Operation via the touchscreen is
quick and easy. Just touch the
TMC symbol in the map, for
example, and the dynamic route
guide via the TMC function
(Traffic Message Channel) is
immediately activated.
