Suspension.
The front axle has a wide-spaced
aluminium double wishbone
arrangement with an aluminium
subframe. The wide spacing
between the wishbones keeps the
forces in the wheel suspension
low for precision wheel guidance
and excellent handling.
The rear axle is an aluminium mul-
ti-link setup. This axle design mini-
mises the pitching of the body
under acceleration and braking.
The high proportion of aluminium
used in the construction of the
axles reduces the weight of
the vehicle and of the unsprung
masses, helping to improve fuel
economy and increase agility.
Steering and Servotronic.
Precise and direct: describes a
typical Porsche steering system
– with variable steering ratio.
Around the straight ahead position,
such as during motorway driving,
the ratio is less direct with no loss
of agility or feedback from the
road. When the steering wheel is
turned further, the ratio becomes
more direct, allowing easier cor-
nering and parking.
Servotronic, a speed-sensitive
power-steering system, is available
as an option for all Panamera
models. At high speeds, the steer-
ing is firm and responds with
extreme precision while steering
comfort remains as high as you
would expect. At low speeds,
Servotronic’s ratio adjusts for
easy manoeuvring and parking.
Wheels and Tyre Pressure
Monitoring (TPM).
The new Panamera and Panamera 4
models are fitted as standard with
18-inch Panamera wheels, the
Panamera S and 4S with 18-inch
Panamera S wheels. All wheels
are lightweight alloys featuring a
classic sporty design. Tyre sizes
245/50 ZR 18 and 275/45 ZR 18
are fitted to the front and rear,
respectively.
The Panamera Turbo is equipped
with 19-inch Panamera Turbo alloy
wheels as standard. The tyres
are slightly wider to cope with the
increased power output of this
model: 255/45 ZR 19 at the front,
285/40 ZR 19 at the rear.
A selection of 18-inch to 20-inch
wheels is available from our range
of options (p. 147).
19-inch all-season tyres are
offered as an alternative at no
extra cost for all Panamera
models with standard or optional
19-inch wheels. A low-rolling
resistance version of these tyres
is available as an option*. The
three main components of the
Panamera Turbo front axle
Panamera Turbo rear axle
19-inch Panamera Turbo wheel 18-inch Panamera S wheel 18-inch Panamera wheel
tyre – the rubber compound, the
tread pattern and the architec-
ture of the tyre substructure –
have been optimised to minimise
roll resistance and thus improve
fuel economy, with no effect on
comfort or performance compared
with the regular 19-inch all-season
tyres.
For increased comfort and safety,
Tyre Pressure Monitoring (TPM)
sends warnings to the on-board
computer’s display screen in
the event of low tyre pressure as
well as in the event of a loss of
pressure. The system is available
as an option for the Panamera
and Panamera 4 and is standard
in all other models.
