Sept. 1963, 901
With the introduction of the Type 901, the Porsche Company has added another car
to round off the upper end of their current program of fast and economical automobiles.
The new model was designed in the best of Porsche tradition, combining the virtues
of the well proven Type 356 models with ideas and experience gathered by the technical
staff of designers and development engineers over a period of many years. Being
equal to the Carrera 2000 GS in weight and temperament, and even excelling it in top
speed, the Type 901 will again demonstrate that in a Porsche driving is at its best.
This car will provide unequalled driving comfort, handling, and safety - qualities
which the demanding Porsche owner has enjoyed ever since the introduction of the
The engine is an air cooled, opposed six cylinder unit with one camshaft for each
bank of cylinders (ohc). Applied in this design are concepts conceived and proven
in the course of development of Grand Prix engines and high performance sports car
engines. The crankshaft is mounted in eight main bearings. Component parts are, to a large degree, of light alloy. This engine was designed with due consideration
towards its adaptability for competition use in appropriate stages of development.
The two camshafts are chain-driven, a feature applied in Porsches for the first time.
A new transmission has been designed for this car. Although similar to the previous
units in mechanical operation, the new transmission has five forward speeds to cope
with the extended speed range.
The front wheel suspension consists of the shock absorbers and low positioned transverse
control arms, with springing effected by longitudinal torsion bars. Suspension
of the rear wheels is by longitudinal control arms with transverse torsion bars. Power
is transmitted to the rear wheels by twin-joint half-axles.
The rack-and-pinion steering is positioned in the forward center of the vehicle. Owing
to this arrangement, which necessitated the utilization of relay shafts in place of a
solid steering rod, the aspect of interior safety has been greatly enhanced. The car
is equipped with disc brakes on all four wheels.
In view of considerations given to body dimensions, it became necessary to consolidate
the new components into a compact unit. The inside space has been enlarged
while keeping the outside dimensions down - here exceeding the overall length of the
Type 356 by only 120 mm, yet reducing the overall width by 70 mm. At the same time
larger window areas have been provided, to satisfy the demands of today.
Despite of the reduced overall width, it was possible to widen the forward passenger
space. Retained basically unchanged is the seating arrangement which provides
utmost comfort on long distance trips. Leg room behind the forward seats has been
extended by approximately 6 cm. Both front fenders have been made detachable to
A special effort was made to provide an adequate solution to interior ventilation. The
spacious luggage compartment under the front hood of the car provides adequate
space for the accomodation of suitcases and other luggage.
