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.

Steering and Servotronic.
Standard equipment on the
Panamera S Hybrid includes Servotronic, a highly precise,
speed-sensitive power-steering
system. At high speeds, the
steering is firm, while at low speeds Servotronic adjusts for
easy parking and manoeuvring.
Even during purely electric driving.

Wheels and Tyre Pressure
Monitoring System (TPM).
The new Panamera S Hybrid is
fit ted as standard with 18-inch
Panamera S alloy wheels in a
10-spoke light weight design with
245/50 ZR 18 front t yres and
275/45 ZR 18 rear t yres.
On request, other 18, 19 or
20-inch wheels are available from
our range. The optional 19-inch
All-season t yres are also available
in an optimum rolling resistance
design – for reduced fuel consump -
tion
with a simultaneous increase
in driving performance.
The standard Tyre Pressure
Monitoring System (TPM) gives a
warning in the on-board computer
display when a t yre pressure is
too low or if there is a gradual
or sudden loss of pressure. For
increased comfort and safet y.

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.
