Steering.
Sensitive and direct, the power-
assisted steering also of fers
accurate feedback from the road.
For a sportscar, driver effort is
minimal. In short: all the precision
of a race- designed system, yet
perfect for everyday road use.
One of the key features of the
steering system is the variable-
ratio gearing. Around the
straight-ahead position, the ratio
is less direct, enabling smoother
manoeuvres on the motorway. It
also reduces the risk of excessive
steering inputs which could
destabilise the car at high speed.
Agilit y and feedback, however,
are maintained.
Turn the wheel harder and the
ratio becomes more direct,
enabling bet ter control through
low-speed corners as well as
easier parking manoeuvres.
The turning circle is a modest
10.9 metres.
19-inch 911 Turbo II wheels.
Fit ted as standard to 911 Turbo
models, the 19 -inch 911 Turbo II
wheels seamlessly combine
function and design.
The car has 8.5 J x 19 wheels
at the front combined with
235/35 ZR 19 t yres. At the rear
are 11 J x 19 wheels with
305/30 ZR 19 t yres. The wheels
are forged, of course, to reduce
weight and unsprung masses.
The material is also very strong,
making it possible to achieve a
fine spoke wheel design which
provides bet ter ventilation of the
brakes.
The five-spoke design is st ylish
and distinctive. The linear
t win spokes have a high -sheen
surface finish, contrasting
with the titanium - coloured base
paint. Part of the wheel rim
also has a high -sheen finish.

Proof that dynamism can be
expressed visually.
19-inch RS Spyder wheels with
central locking device.
Reminiscent of the classic
RS Spyder design, these forged
aluminium wheels with a
motorsport-derived central locking
device are available on request
for the 911 Turbo models and are
fit ted as standard to the new
911 Turbo S models. By reducing
rotating masses, they deliver
an even more agile driving expe -
rience. Benefiting from innovative
ongoing developments to the
engineering conventionally used
only in a racing environment, the
striking central locking devices
of fer ef fective protection against
corrosion and are easy to clean.
Alternatively, the 19 -inch
911 Turbo II wheels are available
for the 911 Turbo S models at no
extra cost.
Tyre Pressure Monitoring
(TPM).
Tyre Pressure Monitoring,
included as standard equipment,
warns against t yre pressure
loss. The driver is informed via
the on -board computer display.
The driver can check the pres -
sures of all four t yres from the
instrument cluster. Each time
the t yres are re-inflated, or when -
ever a wheel has been changed,
the updated t yre pressures are
displayed quickly – for increased
comfort and safet y.
