are reduced thanks to lengthy
replacement intervals for both
the engine oil (18,000 miles) and
air filter unit (36,000 miles). The
spark plugs require changing after
36,000 miles or a maximum of
every four years. The generator,
power-steering pump and air-
conditioning compressor are all
driven by a single self-adjusting
belt with a service life of 54,000
miles. The hydraulic tappets
provide automatic adjustment of
all valve clearances, while the
drive chains on the camshafts
and auxiliary shafts will also last
the life of the car.
Basic servicing is required after
18,000 miles or a maximum of
two years on the road. The first
major service is due at 36,000
miles or every four years at the
latest. The results: lower running
costs and virtually uninterrupted
enjoyment from your Porsche.
Exhaust system.
The exhaust system on the
911 Turbo is made from highly
durable stainless steel. The
system consists of two separate
tracts, one for each bank of
cylinders. The catalytic converters
are extremely heat-resistant,
yet quick to reach temperature
(and thus optimum performance)
when the engine is started
from cold.Twin lambda sensors in each of
the exhausts enable continuous
monitoring of the combustion
process. An additional pair of
sensors* is used to measure
the efficiency of the catalytic
converters.
Servicing.
Another pleasant surprise on the
new 911 Turbo is the standard
service schedule. Running costs
The new six-speed manual
gearbox in the 911 Turbo is
specifically adapted to the car’s
high levels of engine torque.
Designed primarily for sports
driving, one immediate
characteristic is the perfectly
judged spread betweensuccessive ratios as you upshift
through the gears. The gearshift
throw is short and precise,
with only minimal force required.
Thanks to a dual-mass flywheel,
this uncompromising setup means
there’s never any compromise
in comfort. The linkage provides
a direct connection with the
gearbox while insulating
the lever from engine vibration.
One final detail – the new gear
lever design – is exclusive to
the 911 Turbo.

Complementing the front airbags
is the latest generation of Porsche
Side Impact Protection (POSIP).
This comprehensive package
includes two additional airbags for
each front seat: a thorax airbag
in the side of each backrest,
and a head airbag located in each
door. Each side airbag has anapproximate volume of 8 litres,
ensuring maximum protection
over the entire seat adjustment
range. Also incorporated within
the POSIP package are side-
impact protection beams in the
doors.Other standard features include
integral head restraints, an
energy-absorbing steering column,
height-adjustable three-point seat
belts with pre-tensioners and
force limiters, energy-absorbing
structures in the dashboard area
and flame-retardant materials
throughout the interior. The new 911 Turbo has a unique
passive protection system
featuring six separate airbags.
The full-size front airbags for
driver and front passenger have
a two-stage inflation capability.
With this technology, the
deployment of each airbag is
dependent on the force and
nature of the accident (e.g.,
frontal or diagonal impact). In
a low-speed crash, the airbag
is only partially inflated, thereby
minimising discomfort to the
occupants.
The airbag control unit is located
in the centre tunnel where it
receives additional information
from a pair of impact sensors near
the headlights. This arrangement
enables faster and more accurate
evaluation of impact forces in the
event of a crash.
