VarioCam Plus.
VarioCam Plus is a two-in-one
engine concept which adapts to
the particular demand for power.
The system switches seamlessly
thanks to the engine management
system. The result is spontaneous
acceleration and smoother run-
ning.
At medium revs and low engine
loads, the system reduces fuel
consumption and emissions by
lowering the valve lift settings
and advancing the timing. Fuel
economy is especially noticeable
at lower revs. High torque values
and maximum power are achieved
with the high valve lift setting,
which results in exceptional engine
power with comparatively low fuel
consumption.
Expansion intake manifold.
Essentially, in all intake systems,
as well as flowing through, the
air also vibrates. These vibrations
consist of both a compression
phase in which the air is com-
pressed and also an expansion
phase in which the air expands.
Until now, more air has meant
more power. The compression
phase of the air vibrations in the
intake system is used to press
more air into the combustion
chamber. The disadvantage is
that, when it is compressed, the
air is also heated. It is therefore
impossible to achieve optimum
ignition of the fuel and air mixture
to maximise power.The expansion intake manifold
adjusts the air vibrations in a com-
pletely different way. It uses the
expansion phase because, when
it expands, the air cools. The mix-
ture in the combustion chamber
therefore becomes cooler – and
optimum ignition can be achieved.
In using the expansion phase,
less air gets into the cylinders.
However, a slight increase
in the charge pressure by the
turbocharger compensates for
this effect. The heating of the
air caused by the higher charge
pressure is in turn compensated
by the charged air cooler. The
result is much higher efficiency
for even greater engine power
and improved fuel consumption
at high loads and engine speeds.
In principle it is quite easy to be in
awe: just breath deeply.
Power transmission.
The light weight six-speed gearbox
in the 911 GT2 RS is designed
specifically for the large amount
of engine power. The gear lever
throw is short and precise – for
rapid and precise gear changes.
Instead of a dual-mass flywheel as
in the 911 GT2, the 911 GT2 RS
uses a single mass flywheel. This
is lighter and the engine can rev
more freely in the upper speed
ranges. Also, the gear ratios have
been readjusted specifically for
use on the racetrack.

Chassis.
Closer to the ground – yes. On its
knees – no. The requirements for
the new 911 GT2 RS chassis were
high: driving characteristics that
are typical of a race car, on both
the road and the racetrack.
This car is around 25 mm lower
than the 911 Carrera and its sys-
tematic lightweight construction
keeps the total weight and the
weight of unsprung masses low.
For extraordinary agility, excellent
driving safety and stability, espe-
cially when cornering.
Wider wings on the front axle enable
a 12 mm wider toe angle com-
pared to the 911 GT2 and the use
of wider tyres. For even more
grip, improved steering and higher
cornering speeds.
The front suspension with
enhanced hub carriers combines
McPherson-type struts with longi-
tudinal and transverse links. Each
front wheel is precisely located,
ensuring excellent directional
stability and superior handling in
every driving situation.
The rear axle has multi-link suspen-
sion featuring LSA construction –
light, stable and agile. The reduced
weight design of the rear axle’s
aluminium transverse arm and
diagonal struts ensures excellent
driving dynamics.
Ride height, camber, toe angle and
also the stabilisers on the chassis
can be adjusted on the front and
rear axles and therefore adapted
to the required driving behaviour. The rigid connection bet ween the
chassis and the body, e.g. metal
support bearings with ball joints
at the front and the rigid cross-
members at the rear, makes trans-
mission less elastic and ensures
more precise steering to enable
better handling.
Cooling air is delivered efficiently
to the front brakes thanks to
the brake air spoiler. In the new
911 GT2 RS there is additional
brake ventilation on the rear axle.
In short, the chassis exploits the
road to the full. Inspiring awe.
Wheels.
The link between the enormous
power of the new 911 GT2 RS and
the road: the white gold metallic
painted 19-inch GT2 RS wheels.
Their central locking device is
anodised and bears the ‘RS’ logo –
also in a white gold metallic finish.
The central locking device is
derived from motorsport. Its
advantages include bet ter driving
dynamics and performance thanks
to lower rotating masses. And,
of course, faster wheel changes.
An enormous advantage – espe-
cially on the racetrack.
The dimensions: on the front
axle 9 J x 19 with sports tyres
1)
245/35 ZR 19 and on the rear
axle 12 J x 19 with sports tyres
1)
325/30 ZR 19. Tyre Pressure
Monitoring (TPM) comes as stand-
ard and provides early warning
of any tyre pressure loss via a
display on the on-board computer.
You can still take off
without losing contact with the ground.
