success which is
a brilliant triumph for its
basic principle.
The motoring public
has itself written the account
of that success in
the form of sales records.
For Cadillac sales have
exceeded the total volume
of all other cars of the
same price or higher. And
the public has invested
in motor cars powered
with the famous Cadillac
V-type eight, a total of more than one and a half billion dollars—
an imposing total, of which approximately one-third was attained
in the past four years.
A second achievement came when Cadillac engineers developed
for this engine the compensated crankshaft. This step was one of the
most important developments in the history of automotive engineering.
The engine was completely redesigned so that it became,
in effect, four V-type engines of two cylinders each, working on a
crankshaft that had been compensated so as to produce perfect
balance. Vibration was further reduced. Power and smoothness
were greatly increased. This change released the full potential energies
of the V-type, eight-cylinder principle, and resulted in an
amazing smoothness of operation.
Today, this engine continues to stand pre-eminent in the fine
car field, and is the newest, most modern power plant in the industry.
It possesses superior performance characteristics which no
other type of engine can deliver. It is inherently balanced, inherently
smooth-running, inherently efficient. And as built by Cadillac
for these newest style creations, it attains utmost performance.
SEVEN SUPERIORITIES
The fundamental advantages of Cadillac engine design may be
summarized by the following unquestioned facts, every one a clearcut
advantage to the Cadillac owner.
1, The Cadillac engine is short.
The crankshaft of an automobile engine is subjecLed to extreme
twisting strains. These cannot be avoided; they arise inevitably
from the process of translating
the up-and-down
motion of the pistons into
the rotating motion of
the shaft. Obviously, the
longer the shaft, the more
readily it responds to
these strains; the shorter
it is, the less it is affected
by them.
In precisely the same
way, a short crankcase has
more inherent strength
and stiffness than a long
