benefits, such as optimum econ-
omy, emissions and performance
in all driving scenarios.
One of the most important tasks
performed by the engine manage-
ment system is cylinder-specific
knock control. By preventing pre-
ignition at high engine speeds
and loads, this function can avert
costly damage to the pistons and
cylinders. Since temperatures
tend to vary across the engine,
each cylinder is monitoredseparately. If a risk is detected,
the individual ignition timing is
adjusted.
The on-board diagnostics system,
designed to European standard,
quickly detects any faults in the
exhaust and fuel system and
displays them during driving
via the car’s instruments. The
benefits include active prevention
of harmful emissions as well
as consistent rates of fuel con-
sumption.Input data Used to regulate /control

Engine management system.
The Motronic ME7.8.1 engine
management system facilitates
optimum performance at all
times. This high-precision ECU
controls all engine-related func-
tions and assemblies (see
dia-
gram), such as Variable Turbine
Geometry, VarioCam Plus and
the electronic throttle, one of the
key prerequisites for the standard

The 911 GT2 |Comfort
* Child restraint systems may not be used in conjunction with sport bucket seats.
Sport bucket seats.*
A car that is capable of such
extreme lateral loads requires a
seat with exceptional support. The
standard sport bucket seat has
manual fore/aft adjustment plus
two additional features rarely
encountered on comparable seat
designs: a folding backrest and
an integral thorax airbag in the
side support.The folding function enables easy
access to the rear luggage area.
The backrest pivots are positioned
high in the side bolsters, providing
optimum support for the torso,
pelvis and legs. This is the first
time ever that the lateral support
of a bucket seat has been com-
bined with a folding backrest.The backrest shell has a glass-fibre
reinforced plastic core and a
carbon-fibre surface with visible
weave pattern. This construction
provides excellent rigidity while
also reducing weight. The seat is
compatible with a six-point racing
harness.
The sport bucket seat features
black leather with Alcantara centre;
Dark Grey natural leather withAlcantara centre is also available
as an option. In conjunction with the
Clubsport package (see page 64),
it has a special flame-retardant
fabric finish for added safety.
Adaptive sports seats.
Adaptive sports seats in leather
with Alcantara centre are also
available as a no-cost option. This
alternative seat option combines
excellent comfort with first-rate
track performance. The compre-
hensive range of power adjustment
controls includes fore/aft position,
squab height, backrest angle and
lumbar support. The side bolsters
on the backrest and squab arepneumatically adjustable for the
perfect fit. This exceptional vari-
ability ensures generous comfort
on long-distance journeys or
precision support on the race-
track. A memory function includes
both exterior mirrors as well as all
seat settings on the driver’s side,
with the exception of the side bol-
sters. The adaptive sports seats
are also optionally available with
seat heating.
Storage compartments.
The everyday usability of the
911 GT2 is as important as its
performance, as evidenced by
the storage compartments in thecentre console and door panels.
Matching upholstered armrests
above the storage compart
ments
provide optimum driver comfort,
particularly on long-distance trips.
Twin cupholders for driver and
front passenger are neatly
concealed below the passenger
airbag. Underneath is a lockable
glove compartment with handy
CD storage.
Two 12-Volt sockets (including the
cigarette lighter) provide power
for all your accessories.
