VarioCam Plus.
VarioCam Plus is a two-in-one
engine concept for adjusting the
intake camshafts and switching
the lift of the intake valves.
The system first differentiates
between driver inputs that typify
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 in -
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 two
turbochargers arranged in parallel.
Intake air is compressed and then
fed to the engine via two charge-
air coolers, one for each cylinder
bank. Cooling of the compressed
air has two 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 throttle in the
2,000 rpm to 5,000 rpm range is
temporarily increased by up to
10 % by the ‘overboost’ function.

Lightweight exhaust system.
The exhaust system is made from
selected longlife stainless steel.
The powerful primary and main
catalytic converters heat up
rapidly for effective 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 between
two 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.
Activated by a separate button, it
produces an even more authentic
sportscar sound.
