(from Porsche Press
Release) The Specialist for Long-Distance Rallies: the Cayenne S
Porsche is adding yet another highlight to the Company's wide range
of customer sports activities: the Porsche Cayenne S Transsyberia
based on the new Porsche Cayenne S and serving as the perfect
vehicle especially for long-distance rallies.
This ultra-sporting offroader is making its debut in the
Transsyberia Rally taking contestants from Moscow all the way though
Siberia to Ulaanbaatar in Mongolia from 2-17 August.
The Porsche Cayenne is well-known and admired for its outstanding
onroad qualities in the SUV segment. Now the second generation,
which is making its debut at Porsche Centers the world over at this
very moment, moves up this benchmark to an even higher standard. The
new power units with direct gasoline injection, for example, provide
even more power and performance on less fuel, cutting fuel
consumption by up to 15 per cent versus the former models.
Another highlight is Porsche's new PDDC Dynamic Chassis Control
featuring two active anti-roll bars to almost completely eliminate
body sway in bends.
Off the beaten track, the new Cayennes are naturally also on home
ground, maximum axle articulation ensured by PDDC when driving
offroad serving to further improve the already superior traction
offered by the electronically controlled all-wheel drive.
Last year two private teams participated in the Transsyberia Rally
for the first time with the Porsche Cayenne S, finishing first and
second in their very first attempt. Attracted by the successful
participation of these two cars, Porsche has obviously become aware
of the event and, in response, now offers the dyed-in-the-wool
Cayenne driver the option to enter motorsport successfully with
this outstanding model.
To ensure such superiority in motorsport, Porsche has enhanced the
already very good offroad qualities of the Cayenne to an even
higher standard, developing a special model suited particularly for
successful participation in long-distance rallies. Precisely this is
why the new Cayenne S Transsyberia being built from the beginning in
a small series of just 26 units comes, inter alia, with extra-rough
special offroad tyres, a safety cage, a shorter final drive ratio, a
transverse lock, a reinforced, even larger underfloor cover, as well
as beefed-up track control arms on the front axle. At 385 bhp (283
kW), engine output of the eight-cylinder remains unchanged.
Now sporting, ambitious Porsche customers will be participating at
the wheel of a Cayenne S Transsyberia in one of the last adventures
in the world on four wheels – the Transsyberia Rally. From 2-17
August, they will be following the route of this very demanding
orientation rally from Moscow all the way through Siberia to the
finish line in Ulaanbaatar in Mongolia. In all, they will be
covering almost 6,200 kilometres or 3,850 miles on public roads,
gravel tracks and the toughest trial paths, even crossing rivers and
taking special tests in the Gobi Desert. And while navigation is
perhaps the biggest challenge on the long stages of the Rally, it is
particularly the driver's personal skill and, of course, the
qualities of the car that count in the special trials on tracks
closed to the public.
Twenty-Six Porsche Cayenne S Transsyberias for a Start
With its intelligent all-wheel drive, high-performance and efficient
V8 direct injection power unit, as well as height-adjustable air
suspension including Porsche Active Suspension Management (PASM),
the Porsche Cayenne S is perfectly prepared for even the toughest
roads and tracks.
Proceeding from the Cayenne S, Porsche's specialists have built a
small series of special models at the Company's Development Center
in Weissach near Stuttgart optimised especially for the demands of
even the toughest long-distance rally: the Cayenne S Transsyberia.
So following the outstanding success of the two Cayenne Teams last
year, no less than 26 customer teams from all over the world are now
entering the Rally with this special rallying version of the Cayenne
S. Clearly, this will give the Porsche Cayenne the opportunity under
extreme conditions to prove its supreme potential in driving
dynamics versus the keenest competition.
The Transsyberia Rally is split up into six categories of vehicles,
with the Cayenne S Transsyberia featuring a 4.8-litre V8 entering
the race in Class 1C for gasoline-powered passenger cars with
engine capacity of more than four litres.
Porsche Customer Sport
This long-distance rally racing activity with the Porsche Cayenne S
Transsyberia forms an additional highlight in the wide range of
customer sport. The broad foundation in this area is provided by
Porsche's Sports Driving Schools, Porsche Clubsport, as well as
popular brand racing series such as the Porsche Sports Cup in
Germany where various versions of the 911 Carrera, mainly top sports
performers such as the 911 GT3 and 911 GT3 RS, prove their sporting
Moving up a level, Porsche offers ambitious amateurs entering the
GT3 Cup Challenges in the USA, Brazil and New Zealand the
opportunity to enjoy the thrill of motorsport in a racing car
closely related to its production counterpart, the 911 GT3 Cup.
The next step is the Carrera Cups in Asia, Australia, Germany,
France, Great Britain, Italy, Japan and Scandinavia, where
semi-professional and professional teams and drivers show their
skills, again driving the 400-bhp Porsche 911 GT3 Cup.
The top series and, at the same time, the fastest brand trophy in
the world is the Porsche Mobil1 Supercup, the only Gran Turismo
racing series to be held exclusively on the occasion of various
races for the FIA Formula 1 World Championship. Again, the exclusive
model raced at these events is the Porsche 911 GT3 Cup.
For years, many customers have placed their confidence in the both
fast and reliable Porsche 911 GT3 Cup and 911 GT3 RSR when
participating in internationally renowned long-distance races such
as the 24 Hours of Le Mans or the 24 Hours of the Nürburgring, the
various races in the American Le Mans Series, as well as the Le Mans
Series or the FIA GT Series.
The RS Spyder sports prototype comes right at the top of Porsche's
customer sports programme, with three teams scheduled to enter the
current season in the middle of the year, racing a total of six of
these 1.25 million-Euro expensive high-tech prototypes in the LM P2
class of the American Le Mans Series.
Porsche Cayenne S Transsyberia
The Sporting All-Round Performer
The Porsche Cayenne S Transsyberia is a typical Porsche through and
through, tailored precisely to the needs and requirements of the
sporting, ambitious customer – which in this case means a car
tailored specifically to the requirements of long-distance rally
Compared with the “regular" version of the Cayenne S, the Porsche
Cayenne S Transsyberia as a special rally version has been modified
on a number of points serving first and foremost to enhance safety
and the car's racing performance.
Production Engine, Shorter Transmission Ratio
The power unit of the Porsche Cayenne S Transsyberia has been
carried over from the regular road version of the Cayenne S with
hardly any changes: Output of this 4.8-litre natural-aspiration V8
with direct gasoline injection remains 385 bhp (283 kW) at 6200 rpm.
Maximum torque of 500 Newton-metres or 369 lb-ft, in turn, comes at
just 3500 rpm.
VarioCam Plus valve management ensures a smooth and consistent surge
of power throughout the entire speed range, with engine management
varying valve lift on the intake side between 3.6 and 10 millimetres
as a function of engine speed. And with the intake manifold also
being variable in length, the engine provides muscular torque right
from the start even at low engine speeds.
Despite the increase in power over the previous engine, the new
4.8-litre reduces fuel consumption by approximately 15 per cent,
giving the Cayenne S a significantly longer cruising range than
before – obviously a big advantage particularly in a long-distance
Automatically detecting the quality of the fuel it is running on,
the engine is also able to run on regular fuel with an octane rating
of 91 or more, even though this will reduce both engine output and
torque. In fact, the engine is also able to run on a mixture of
gasoline and ethanol, with up to 25 per cent of the latter.
A sports exhaust system reduced for minimum weight gives the Cayenne
S Transsyberia a particularly powerful and muscular sound, while
Tiptronic S transmission with a shorter final drive ratio helps to
ensure even better acceleration both from the start and in gears.
And last but not least, the transmission management has been
optimised for offroad use of the vehicle.
Even Better off the Beaten Track
Like all other models in the Cayenne range, the Cayenne S
Transsyberia also comes with Porsche Traction Management (PTM)
permanent all-wheel drive.
In its basic mode, PTM feeds 62 per cent of the engine's torque to
the rear wheels and 38 per cent to the front. Then a multiple-plate
clutch operated by an electric motor and controlled electronically
is able to vary the distribution of power as a function of driving
conditions, if necessary feeding as much as 100 per cent of the
engine's power completely to the front or rear.
The map-controlled longitudinal lock and the differential lock on
the rear axle respond not only to lack of traction on the front or
rear wheels, but also benefit from sensors measuring the speed of
the vehicle, its lateral acceleration, the steering angle and the
position of the accelerator pedal. Using this information, PTM is
able to consistently calculate the degree of lock required on the
two axles and feed precisely the power required to the axle at the
front and rear.
A transverse lock fitted additionally in the Cayenne S Transsyberia
serves to enhance offroad driving qualities to an even higher
standard (and is also available in the regular production model as
part of the optional Offroad Technology Package).
Particularly in heavy terrain, PDDC Porsche Dynamic Chassis Control,
interacting with air suspension and PASM Porsche Active Suspension
Management, enhances traction to an even higher standard. And should
the driver activate the low-range mode on the six-speed automatic
transmission by means of the control paddle, PDCC will automatically
switch over to the offroad mode, the system thus allowing maximum
articulation of the axles.
In the Special Offroad Mode provided by the air suspension, the
maximum depth when crossing rivers and streams, etc, is
approximately 75 centimetres or almost 30". To make such an extreme
depth possible, both the body and the doors are sealed off against
the penetration of water all the way up to the side windows. And
using a flexible air filter snorkel, the air intake has been moved
up even further to the roof of the vehicle, ensuring that the front
wave typical when crossing water is not able to reach, let alone
enter, the intake manifold.
The wheels and suspension of the Cayenne have naturally also been
modified for the most extreme, long-term demands of rough tracks and
rocky surfaces. As an example, the double-arm front axle comes with
reinforced track control arms, with track itself being increased by
34 millimetres or 1.34" for extra stability.
The usual high-speed tyres fitted on the regular model are replaced
by special offroad tyres measuring 255/55 R 18 T and homologated for
speeds of up to 190 km/h or 118 mph. The tyres themselves are fitted
on 18-inch, 15-spoke Cayenne S II light-alloy wheels and the rim
hubs are finished in orange, like on the Porsche GT3RS.
Massive Safety Cell within the Interior
It is already well known that the Porsche Cayenne ranks right at the
top in the offroader market also in terms of body stiffness and
passive safety – which is no surprise, considering that more than 60
per cent of the body-in-white is made of high-strength steel. Forces
generated in an accident are absorbed by three load levels above one
another and fed into the stiff longitudinal floor support, the
side-sills and tunnel areas. The reinforcements in the A- and
B-pillars, in turn, are made of ultra-high-strength steel to improve
safety in a rollover. And to offer both the driver and passenger
even better protection from the consequences of a collision or
rollover under racing conditions, the Cayenne S Transsyberia comes
with a safety cage bolted on to the passenger cell. Indeed, this
cage even follows the rules and requirements of the FIA Motorsport
Authority, with the driver also being protected by an airbag for
Optimised for Minimum Weight All Round
To set off the extra weight of the safety cage and rally equipment,
and to further lower the vehicle's centre of gravity, the rear seat
bench, interior body panels and sound-proofing material have all
been removed from the car. Central locking, in turn, is replaced by
a manual door opening mechanism on the front doors with orange-coloured
opening and closing loops.
Both the rear window and the side windows at the rear are made of
light polycarbonate, while the side windows at the front, as on all
Cayenne models, feature special hydrophobic treatment at the
outside to make water run off more quickly and smoothly and ensuring
that the glass remains far cleaner for far longer than with
As another important advantage, both the driver and front passenger
enjoy the benefits of lightweight sports seats with a leatherette/Alcantara
The new models in the Cayenne range are even more sporting and
dynamic also in their looks than their predecessors. And so it is no
surprise that the Cayenne S Transsyberia comes with the same
brand-new front end as well as the dynamic rear-end design of the
new model enhanced to an even higher standard, extra-large air
intake scoops bearing clear testimony to the car's superior power
On the tailgate the Cayenne S Transsyberia boasts a roof spoiler
with a double-wing profile fitted in position to provide even
greater stability at high speeds. The front and rear air dams, in
turn, are finished in stainless steel, and orange-coloured wheels
give the Cayenne S Transsyberia a sporting look, making the vehicle
easily recognisable at very first sight.
At the side this special rally model proudly boasts orange-coloured
stripes bearing the name “Cayenne S Transsyberia 2007" in a look
similar to that of the Porsche Carrera GT3 RS.
The Cayenne S Transsyberia is available exclusively in two special
colour schemes – either Basalt Black Metallic or Crystal Silver
Metallic. And matching the model designation at the sides as well as
the wheel rims, contrasting elements such as the exterior mirrors,
the rear wing, the additional headlights and crossbars on the
cooling air intakes are all finished in orange.
Wide Range of Rally Equipment
All 26 units of the Cayenne S Transsyberia come as standard with a
navigation unit enabling the team to plan their routes also off the
beaten track, with the navigation system naturally being
masterminded by the passenger for optimum efficiency.
The glove compartment is replaced on this special model by a
Tripmaster computer enabling the co-pilot to exactly scrutinize the
route between individual navigation points on the way.
Most of the control units are fitted within the interior, and all
electric lines and wires have been installed at new points and in
Using a central switch at the right beneath the driver's seat, the
man at the wheel or the co-driver are able to switch the on-board
electrics on and off in one quick and convenient operation, thus
re-setting the electronic system if necessary even while driving.
Air for the engine is drawn in through a special opening above the
engine compartment lid, a snorkel serving to move the air intake up
even higher all the way to roof level, thus ensuring that the front
wave generated when crossing rivers or streams, etc, is not able to
enter the intake manifold.
Reinforced and extra-large underfloor protection panels made of
aluminium and an additional cover made of stainless steel for the
exhaust tailpipes protect the Cayenne S Transsyberia from the
particular damage and exposure easily encountered on a rally with
its extremely tough conditions.
The regular foot-operated parking brake is replaced by a handbrake
enabling the driver to oversteer the vehicle intentionally in a
tight bend. Four additional headlights are fitted on the roof, and
to successfully master particularly difficult and demanding terrain,
as well as to salvage other vehicles, the Cayenne S Transsyberia
comes with a winch easy to fit when necessary and stored for
convenient use in the luggage compartment.
The luggage compartment also comes with two 20-litre reserve cans, a
hydraulic offroad car jack, two fire extinguishers, two sand boards,
two full-size spare wheels, and two transport boxes for tools.
Further features included as standard are two two-man tents, two
heat-insulated mats, four lashing belts, a nine-metre-long salvage
belt complete with tackle, a folding spade, a folding saw, an axe, a
manually operated and adjustable headlight, four towing bar
openings and a complete Hazet toolkit.
