For saloon drivers, it seems,
the interior is no place for engine
noise. But how important is the
engine to you? We thought so. Just
as important as it is to us. This is
why we – like you – are perfectly
happy with that seductive sound.
We – like you – want to hear that
the Panamera models are unmis -
takably Porsche.
When it comes to the environment,
the facts speak for themselves.
Engines with high ef ficiency and
low fuel consumption. High power
output with comparatively low CO
2
emissions per hp.
Low on weight, too. The light-alloy
engines have cast aluminium pis -
tons (Panamera and Panamera S
models) or forged pistons
(Panamera Turbo), aluminium
one-piece cylinder heads and an aluminium crankcase of closed-
deck construction. The casing
and cooling ducts around the

cylinders form a closed system.
The engines are therefore light-
weight for reduced fuel con-
sumption and have a long service
life.
The V6 engine, which is based on
the V8 engine, additionally fea -
tures a balance shaf t to minimise
vibrations and ensure smooth
running.
An integrated dry-sump lubrication
system guarantees a reliable sup -
ply of oil in all driving situations.
Instead of an external oil tank, the
oil reservoir is located directly
inside the engine, which saves on
space and weight.

system ensures optimum engine
performance at all times. In par -

Engines.ticular, it evaluates the signals of
the electronic accelerator pedal
(E- Gas) – a prerequisite for Porsche
Stabilit y Management (PSM, p. 72),
which is fit ted as standard. More -
over, it regulates all engine-related
functions and assemblies. The
results: optimum performance
and torque with reduced fuel
consumption and
emissions,
whatever your driving st yle. Another important function is the
cylinder-specific knock control,
which compensates for dif ferent
fuel grades added to the engine.
Since cylinders never all work
under exactly the same conditions,
the ignition point is shifted indi -
vidually, as and when necessary.
The on -board diagnostics ensure
timely detection of any faults and
defects that may occur in the
exhaust and fuel systems and
notif y the driver immediately. This
also prevents increased pollutant
emissions and unnecessary fuel
consumption.

SPORT button.
All Panamera models are
equipped with the SPORT but ton
as standard. This feature enables
the driver to vary the engine
characteristics and, in vehicles
with PASM, the suspension setup.
In vehicles with Porsche Doppel-
kupplung (PDK), the SPORT
but ton can be used to select a
sportier gearshif t strategy. For
more information, please refer
to page 74.
Auto start/stop function (only
in conjunction with Porsche
Doppelkupplung, PDK).
Silence: the t ypical stationary
noise. If, for example, you stop at
traf fic lights with your foot on
the brake pedal, the Auto start /
stop function will automatically
stop the engine. 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 of f. 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 but ton. The
function may remain inactive under
particular circumstances, e.g.
very high outside temperatures,
on extreme uphill gradients, or if
bat tery charge is low.
The starter has been modified to
meet the increased requirements
demanded by this function and the bat tery is continuously moni
-
tored for the level of charge and
condition. The bat tery and starter
are consumable components and
are subject to an increased rate
of wear in the event of frequent
engine stopping.
Fuel economy is further improved
by electrical system recuperation,
whereby the bat tery is charged
predominantly under braking.
Under acceleration, on the other
hand, the alternator’s charging
current is reduced so that the
engine does not need to work as
hard to charge the bat tery.
Performance | Engines
With millisecond precision, DFI
injects fuel at up to 120 bar di rect -
l y
into the combustion chamber
by means of electromagnetically
actuated injection valves.
The spray and cone angles have
been optimised for torque, power
output, fuel consumption and
emissions by enabling a homoge -
neous distribution of the air/fuel
mixture, and, therefore, ef fective combustion. At up to 3,500 rpm,
the engine operates with dual
injection for faster heating of the
cataly tic converters af ter a cold
start and for greater torque in the
upper load range.
DFI improves the internal cooling
of the combustion chamber by
having the mixture prepared
direct
ly in the cylinder. This allows
for a higher compression ratio, which helps to deliver more out
-
put at the same time as enhanced
engine ef ficiency. Injection is
regulated by the electronic engine
management system and emis-
sions are monitored by the stereo
Lambda sensors, thus helping to
protect the environment.
A sense of relaxation is felt especially
after a period of intense pressure.
Direct fuel injection (DFI).

VarioCam Plus.
VarioCam Plus is a t wo -in - one
engine concept for adjusting the
intake camshaf ts and switching
the lif t of the intake valves.
The system first dif ferentiates
bet ween driver inputs that t ypif y
normal, everyday driving and
those inputs that demand maxi -
mum performance. The electronic
engine management system then
seamlessly adapts valve operation
to the prevailing conditions. This
results in instant acceleration and
extremely smooth running. In the middle and low load ranges,
low valve lifts with advanced

timing reduce fuel consumption
and exhaust emissions and im -
prove smooth running. The i n -
crease in fuel economy is particu -
larly pronounced in the lower
engine speed range. High torque
and maximum output are achieved
through high valve lifts and ad -
vanced timing.
How does this benefit you?
Extraordinary power with
relatively low fuel consumption.
Exhaust turbocharging.
The Panamera Turbo has t wo
turbochargers arranged in parallel.
Intake air is compressed and then
fed to the engine via t wo charge-
air coolers, one for each cylinder
bank. Cooling of the compressed
air has t wo positive outcomes:
high cylinder charge and low com -
ponent temperatures. Under full
load, the boost pressure depends
on the current engine speed and
a maximum pressure of 0.85 bar is
achieved at 2,500 rpm at sea
level.
With the optional Sport Chrono
Package Turbo, the boost pressure
produced at full throt tle in the
2,000 rpm to 5,000 rpm range is
temporarily increased by up to
10 % by the ‘overboost ’ function.
VarioCam Plus
Lightweight exhaust system.
The exhaust system is made from
selected longlife stainless steel.
The powerful primary and main
cataly tic converters heat up
rapidly for ef fective emissions
control. As a result, all Panamera
models are equipped to meet
the Euro 5 emission standard in
Europe.
The exhaust system of the
Panamera Turbo switches bet ween
t wo configurations automatically:
low noise at low engine speeds,
and increased throughput at high
revs under maximum engine load.
Sports exhaust system.
An optional sports exhaust system
is available for the Panamera S
models and Panamera Turbo.
Acti
vated by a separate but ton, it
produces an even more authentic
sportscar sound.
