THE PORSCHE PROGRAM
Our intention right from the outset with the Porsche 911
was to build a sports car which can be entered in competitions straight
off the production line!
But which is so rugged and comfortable that it has all
the good qualities of a sedan in everyday traffic.
And finally, an automobile styled in such a way that it remains
unaffected by fashion influences.
The perfection of the Porsche 911 results
from many years of experience with the vehicle,
observing it in everyday situations and
constantly subjecting the design and details to
critical tests in racing situations.
Before changes are made in the standard production models,
they undergo rigorous testing on the track.
However, it has never been necessary to change the basic
Thus, the 2.4 liter engine does not make it a new Porsche
but rather a better Porsche.
Today, years after the first Porsche 911 made its debut,
we still maintain the same approach to sports car
construction: confront our designers with ever newer
problems in racing sports.
In order to make what's good better.
The result: The Porsche 911 has become the most successful sports car in the world.
Its 6-cylinder high performance engine now has
a displacement of 2.4 liters.
And it is more flexible and stronger.
While the 2.2 liter engines performed very well,
the 2.4 liter engines have increased flexibility and
torque versatility. This means the Porsche 911 is a
better city car and has added sprint for passing.
No changes have been made in the technical details
which arc essentially the same for all three
engines. The six air-cooled cylinders are horizontally
opposed (three to the left and three to the right of
the crankcase) and are covered with light alloy deep ribbed
cylinder heads to reduce thermal stress.
The V-pattern overhead valves are controlled via
rockers by overhead camshafts for each cylinder
bank. The forged, eight-point bearing crankshaft provides
for absolutely vibration-free operation. A dry sump
lubrication system guarantees uniform oil supply
total lubrication points,even when taking curvesat high speeds.
The Porsche 911 series has three different engines.
The 130 DIN HP (147 SAE HP) T model is equipped
with two 3-barrel carburetors - one carburetor
per cylinder. The fuel-air mixture is fed into the
combustion chambers through short manifolds.
The 911 E and 911 S engines are fed by a mechanical
manifold fuel injection. In addition to the
increased power of 165 DIN HP (185 SAE HP) and
190 DIN HP (210 SAE HP) respectively, the Bosch
injection system also has the following advantages:
the fuel-air mixture greatly reduces the output of
unburned hydrocarbons and carbon monoxide. We
at Porsche are very concerned about detoxifying exhaust
gases. This was one of the main reasons for
lowering the compression ratio in the 2.4 liter engine
so that the Porsche can now be driven with lead-free
regular gasoline (91 octane).
All Porsche engines are highly tested, rugged components
which combine high torque reserves with
low piston speed. These engines love nothing better
than to run for hours at high speeds or drive the gears
full out. The engine speed governor makes it impossible
to overspeed a Porsche engine while accelerating.
The Porsche 911 S has an additional oil cooler.
Everyday driving and racing successes are proof
of the high capacity and long service life of Porsche
The Porsche baulk synchromesh transmission
comes in three different versions.
With the higher engine speed and greater flexibility
of the 2.4 l engine, we were able to make a
new reinforced 4-speed transmission standard equipment
on all Porsche 911 's. The transmission and
engine form a single unit providing optimum power
load tothedrive gears.The synchronization is very fast only
short, precise shifting motions are necessary to
find the different gears. The ranges of the various
gears have been precisely tuned to the engine characteristics
and the individual vehicle types. This means
that the top engine capacity is available for every
driving situation. Quick shifting of the Porsche baulk
synchromesh transmission transfers the acceleration
power to the wheels with minimum delay.
As an option, you can have your Porsche equipped
with a 5-speed transmission. Or, with the "Sportomatic" - the automatic transmission for sports drivers.
It combines the advantages of the Porsche 4-speed
transmission with a hydraulic torque converter.
With the Sportomatic you no longer have to shift
but you can when you want to. When driving in
heavy city traffic or in a column on the road you
simply remain in the selected gear. But on the open
road and in sport driving situations you can shift it
like a normal transmission. But without having to
clutch! When you shift gears the Sportomatic clutches
automatically. Thus, the Sportomatic not only saves
your nerves but also all the elements in the drive
train of your Porsche.
It combines the comfort of an automatic transmission
with the sportiness of a standard transmission.
By the way, a Porsche equipped with the Sportomatic
won the 84-hour "Marathon de la Route" -
proof enough of its sporty acceleration.

The chassis - an optimum combination of sporting safety
and driving comfort.
The Porsche chassis clearly shows there is no contradiction
between suspension/ damping comfort and
The independently suspended front wheels are
stabilized by wishbones, in combination with torsion bar
springs and shock absorbers. This means the
wheels maintain independent contact with the road.
More precisely: potholes and rough spots which
affect one wheel have no influence on the smooth
running of the other wheel.
Also the rear wheels are independently suspended.
They are stabilized by semi-trailing arms and
sprung with longitudinal torsion bars and double-
action hydraulic shock absorbers. Anti,roll stabilizers
(standard equipment on the 911 S) are available as
options); they provide for even better roadholding
The wide-rim wheels and tires also contribute to
Porsche's high-speed curving abilities. They reinforce
the braking effect of the chassis substantially, absorb
lateral forces and enable increased lateral acceleration.
In addition, these wheels (15 inches on all Porsches)
have a greater circumference. The advantage
here is a smoother ride on rough roads and longer
life for tires.
The Porsche 911 -
outstanding performance matched with outstanding safety.
With a stronger engine it is easier to avoid critical
traffic situations. The Porsche 911 S accelerates
from 0 to 100 in 7 seconds and insures you of greater
safety when passing. Even at speeds of 200 km/ h
(125 mph) you still have a power reserve if you
For safety, the braking time from 100 to 0 is just
as important as the acceleration from 0 to 100: it
takes exactly 3.2 seconds to come to a complete stop.
Safety here is a dual-circuit braking system with 4
large-dimension disc brakes.
The ventilated discs insure optimum brake cooling.
Even after repeated full-stop braking, they engage
with the same force to stop you in the same
The front apron of the Porsche 911 S functions
as a spoiler. It reduces the up-lift of the front end at
high speeds and increases stable roadholding.
In addition the safe-track and smooth, direct rackand-
pinion steering allows you to react to sudden
obstacles with a quick steering maneuver without
fear of swerving.
Even on inclines and winter ice the optimum
power transfer from the rear engine to the drive
wheels gives the Porsche outstanding roadability.
Passive safety details to reduce danger of accident
were equally as important as active safety in designing
the Porsche 911: a large share of the impact force
is absorbed by the self-supporting all-steel body.
It surrounds a torsionally-rigid passenger compartment.
The front section is a deformable force absorbing
impact zone. The safety roll bar of the
targa version has all the stability and safety of a
For added driver safety, the 911 has a three-piece
offset steering column. In a front-end collision, the
upper and lower shafts bypass one another; the
steering column is not forced into the passenger
Additional passenger safety is provided by the recessed
steering wheel and the padded horn ring as
well as the padded instrument panel with the deep recessed,
non-glare instruments, smooth, padded or
flexible control knobs and the laminated safety glass
All of these factors taken together make it obvious
why, for many drivers, the Porsche 911 offers
the greatest measure of safety, even in racing situations.
Comfort is not an "extra" in a Porsche.
With all the Porsche racing victories it is easy to
forget that the vast majority of Porsches are driven
in normal, everyday traffic, on business and weekend
trips. Therefore we have designed the Porsche
to offer at least as much comfort as an expensive
sedan. And, with much more than one expects from
a sports car.
The interior design and instruments are clean and
functional. This means that you can reach all control
elements quickly and effortlessly. For example -
without taking your hands off the steering wheel or
your eyes from the road - you can operate either of
the two combi-switches on the steering column to
control the three-stage windshield wipers, the windshield
washing unit, the directional indicators, the
headlight flasher and the dimmer switch. The glare free
control gauges lie in the driver's field of vision:
tachometer, speedometer with trip odometer, oil temperature
and oil pressure gauge, oil reserve gauge and
fuel gauge constantly report on the operational condition
of your Porsche.
The Porsche 911 also offers many other details
to make driving pleasant for you. There is the draft free
ventilation unit with forced exhaust, the separate
(for driver and passenger) ventilation and heating
systems with a three-stage blower, the electrically
heated rear window, an electric windshield
washing unit, halogen headlights, back-up lights and
an electric clock with elapsed time indicator.
The width and depth of the Porsche interior have
been designed to give the driver and passenger unencumbered
free movement. The two anatomically-contoured
front seats lie around the car's center of gravity.
The shell form of the seats provides you with
lateral holding so that you do not have to hang on to
the steering wheel for support in sports car curves.
Longer stretches of highway driving will show you
just how comfortable the reclined seats are.
The 200 lifer (7.1 cu. ft.) luggage compartment
can be more than doubled.
The space-saving front axle design takes up so
little room in front that a wide 200 l (7 .1 cu. ft.)
luggage compartment is possible.
It is completely lined with needle felt carpeting
to prevent your luggage from slipping, sliding or becoming
damaged on the edges.
The rear engine of the Porsche 911 leaves ample
room for two jump seats in back. And if the front
luggage compartment is not sufficient, you need only
reach behind you and fold the jump seats down. You
now have a rear luggage compartment with approx.
235 1 ( cu. ft.).
All told, as much luggage space as a middle class
sedan. Very unusual for a sports car.
A Porsche is not new until it is 35 km old.
The more technically sophisticated a car is, the
more carefully it must be tested. The Porsche has to
pass a whole series of demanding tests before it is
released for delivery.
We test the engine first. Before it is assembled,
each individual part is carefully checked for quality.
For example, the valves and camshafts are checked
for weight, imbalance and tensile strength.
The reassembled engine is checked on the testing
stand for power output, spark adjustment and fuel
consumption. After all these tests comes the final and
deciding test for the finished vehicle: by the Porsche
Everything in the car is systematically checked for
functional reliability on driving test stands and finally
over a 35 km test course: engine performance, power
transmission, chassis adaptation, steering precision,
braking capacity, tire quality, et cetera.
But, Porsches already have the best test run behind
them before they are even built - the race track.
There are many more people who can
afford a Porsche 911
than have the spirit for one.
If the acquisition of a Porsche were merely a question
of money, many more drivers would be buying
The reason they do not is that this car requires
something more special than the multi-digit bank
The sports car spirit!
For anyone who does not have the spirit, Porsche
is still a beautiful car which leaves everything else on
the road behind .. . but nothing more.
That the Porsche is more - perhaps a motoring
world of its own - is shown by its technology,
its performance data and its external appearance, all
of which are perfected down to the seemingly least
But, you don't really know a Porsche until you

The Porsche outdoes the average automobile not only
in terms of performance, sportiness and technical perfection
but, of course, also in price.
This is the reason why many people who dream
of owning one must· dream a long time before they get
their first factory-new Porsche.
However, why not shorten the waiting by starting with
a second-hand Porsche? The risk involved with a used
Porsche is often much less than with other used cars.
Also, through our world-wide service organization,
we make sure all Porsches are maintained and repaired
with the same perfection that is built into them.
Porsches are and remain rugged and reliable to an extent
that can be expected from very few other vehicles.
Let alone from any other sports car.
