Direct fuel injection (DFI).
With millisecond precision, DFI injects
fuel at up to 120 bar directly into the
combustion chamber by means of elec-
tromagnetically actuated injection valves,
thus ensuring homogeneous distribution
of the air/fuel mixture, and, therefore, effective combustion. As the mixture

is prepared directly in the cylinders,
DFI improves the internal cooling of
the combustion chambers compared
with that of a manifold injection system.
The achievable compression ratio of
12.5:1 helps to ensure a high level of
engine efficiency.
VarioCam Plus.
The Panamera GTS is also equipped
with VarioCam Plus which automatically
adjusts the intake camshafts and
switches the lift of the intake valves.
In the middle and low load ranges,
low valve lifts with advanced timing
reduce fuel consumption and exhaust
emissions and improve smooth
running. High torque and maximum
output are achieved through high
valve lifts and retarded timing.
How does this benefit you? Extra-
ordinary acceleration power with
comparatively low fuel consumption.
Auto start/stop function.
The auto start/stop function is also
standard in the Panamera GTS. If, for
example, you stop at traffic lights and
keep your foot on the brake pedal, the
system will automatically switch the
engine off. This fuel-saving system
restarts the engine as soon as you
release the brakes.
A key advantage is that there is no
need for you to change your driving
habits. You can simply carry on as
normal. All audio and communication
systems remain switched on and the
climate control continues to maintain
your selected temperature, despite the
engine being switched off. The engine
restarts if more power or extra cooling
output is required.
The auto start /stop function can be
activated and deactivated using a
separate button. The function may

cumstances, e.g. in very high outside
temperatures, on extreme uphill
gradients, or if bat tery charge is low,
and will be deactivated if SPORT or
SPORT PLUS mode is activated (p. 28).
Sports exhaust system.
The Panamera GTS is equipped as stand -
ard with the sports exhaust system
featuring tailpipes painted in matt black.
The exhaust system is made from
long-life stainless-steel alloys. The
powerful primary and main catalytic
converters heat up rapidly and help
to deliver ef fective emissions control.
When a separate control but ton is
pressed or SPORT or SPORT PLUS
mode is activated, the sports exhaust
system switches to a characteristic
motorsport sound, eclipsing even that
of the other Panamera models.

SPORT buttons and
Sport Chrono P ackage.
The Panamera GTS is more sport-oriented
than the other models in the Panamera
range. You can feel it and you
can hear
it the moment you start the engine and
depress the accelerator. With the SPORT
and SPORT PLUS
buttons, both of which
are available as standard, you have a
choice bet ween
t wo modes to make your
Panamera GTS
driving experience more and measure distances, it can also be
used as a conventional clock.
Another key component is the perfor
-
mance display in the standard Porsche
Communication Management (PCM, p. 36),
which enables you to view, store and
evaluate recorded times. It shows the
total driving time, current lap distance,
lap number and lap times recorded so
far. You can view the current fastest lap
and the remaining range until empt y.
Travelled distances can be recorded
and defined as benchmark distances.
direct and
dynamic. When the SPORT
button is selected, the electronic engine
management system adapts for sportier
performance driving. In response to
pedal input, a more dynamic throt tle
map opens the throt tle valve wider than
would be the case in Normal mode.

The throt tle response is significantly

more immediate and a harder rev-limiter
is applied. PDK shifts up later and shifts
down sooner. Porsche Active Suspension
Management (PASM) and the optional
Porsche Dynamic Chassis Control (PDDC)
also switch to SPORT mode to deliver
harder damping and more direct steering,
which provides greater agilit y through
corners.
The SPORT PLUS but ton activates
SPORT PLUS mode. The adaptive air
suspension of the Panamera GTS drops
the chassis to Low Level and hardens the spring rate. Offering involving perfor
-
mance, PDK is now geared for extremely
short shift times and optimum shift
points for the maximum acceleration
available. In automatic mode, PDK
responds to the slightest deceleration –
even at high engine speeds – with a
swifter brake-induced downshift. In
response to downshifts in manual mode,
the electronic engine management
system initiates a purposeful increase
in transmission speed to suppress
load- change reactions.
In SPORT PLUS mode, the trigger thresh -
old for PSM is raised for increased
longitudinal and lateral dynamics. Agility
is further enhanced when braking for
corners with PSM enabling greater
manoeuvrability under braking and exit
acceleration, especially at low speeds.
For even greater dexterit y, PSM can be set to standby while the car is still in
SPORT PLUS mode. For safet y, it
remains set to intervene automatically
only when ABS assistance is required

on both the front wheels.
Optimum acceleration from a standing
start is provided by the ‘Launch Control’
function. This function is operated via
the SPORT PLUS but ton with the ‘D’ or
‘M’ drive position selected. With the left
foot depressing the brake pedal, the
driver fully depresses the accelerator
for maximum throt tle. ‘Launch Control’
now appears in the SportDesign steering
wheel spoke display. Now simply release
the brake and feel the acceleration
power unleashed to the road.

board is a component of the Sport Chrono
Package. Designed to record lap times

Panamera Turbo. The brake disc dia-
meters are 390 mm and 350 mm at

the front and
rear respectively. The discs
are internally vented and slot ted for
improved heat dispersal and braking
even under extreme conditions.
The electric parking brake, which
can be activated manually, releases
automatically as you pull away.
Porsche Ceramic Composite Brake
(PCCB).
The track-tested Porsche Ceramic
Composite Brake (PCCB) is available
on request (only in conjunction with
20 -inch wheels). The diameters of the
cross- drilled ceramic discs are 410 mm and
350 mm at the front and

rear respectively.
PCCB is characterised by its low thermal
expansion, which prevents deformation
under heavy braking. Furthermore, the
ceramic brake discs are totally resistant to
corrosion and offer more favourable noise-
damping properties.
The key advantage of PCCB is the
extremely low weight of the ceramic
brake discs, which are approximately

50 % lighter than standard discs of similar
design and size. As well as enhancing
performance and fuel economy, this

represents a major reduction in unsprung
and rotating masses. The results are
improved handling, better road holding
and increased comfort, particularly on
uneven roads.
Brakes.
The brake system of the Panamera GTS,
which features six- piston monobloc
aluminium fixed brake calipers at the
front and four-piston units at the
rear, has been carried over from the

Environment.
Porsche has reduced the CO2 emissions
of its vehicles by an average of around
1.7 % every year for the past 15 years
and by 4.6 % from 2006 to 2010.*
As far as engine output is concerned,

we are already among those manufactur -
ers achieving the lowest CO
2 emissions.
This has been achieved through efficient
drive concepts, lightweight construction,
optimum aerodynamics and low rolling
resistance. In this way, Porsche demon -
strates that even high performance
sports cars can achieve moderate fuel
consumption and exhaust emission
values in their respective category.
How? Through the use of fuel-efficient
technologies such as direct fuel injection
(DFI), VarioCam Plus, auto start/stop and

electrical system recuperation, whereby
the vehicle bat tery is charged
predominantly under braking.
Furthermore, the bodyshell of the
Panamera GTS has an alloy content of
around 23 %. The bonnet, doors, front
wings and rear hatch, for example, are
made of aluminium, which saves weight
and reduces fuel consumption.
