Comments from engineers. distribut-
ors and owners indicate that of all the
pioneering achievements of the Cadil-
lac Motor Car company during the last
q years, none has contributed more
to riding comfort than the creation of
the new "6S"- inherently balanced and
harmonized engine, according to Frank
johnson. assistant chief engieer of
the company, who assisted in design
ing the first one-cylinder Cadillac en-
CINE and who has had an important
part in the designing of nearly every
new Cadillac since that time. accord
ing to the Mahford Cadillac company
local distributor.
"During the month of March, :"
states Mr.. johnson, We are celebrating
the sixteenth anniversary of the award
to Cadillac of the Dewar trophy by
the Royal Automobile Club OF Eng
land for the most significant develop
ment during the preceding year.
Introduces V-Type Here.
Since that time our company has
also pioneered in such fundamental

ing electrical ignition; introducing a
complete electrical system of cranking,
lighting and ignition; developing and
using thermostatic control of the cir
culating cooling medium and of cur
buretion; and introducing V-type, high
speed automobile engines in the
United States.
yet, from the standpoint Of per-
formance," Mr.. johnson continues,
"the creation of our new engine an
nounced in the fall of 1923 is now
generally accepted as our most funda-
mental achievement since introducing
into this country the V-type, eight
cylinder engine in 1915.
"The principle involved. giving to
the V-type, 90-degree engine, an abb
solute equilibrium of all moving parts.
which renders it entirely smooth in OPP
Grafton, is a new principle. Both in de-
velopment and application it is orig
inal with the Cadillac organization.
Power Increased Greatly.
@The history of the development of
that new principle would in itself
make an interesting story as 1t COW
ers long period Of close application
and many experiments by both our
own and General Motors Research
Laboratory engineers
"The external. appearance OF this
new engine is quite similar to that OF
previous Cadillac types. For that rea-
son many have not realized until they
have ridden in one of the new cars
that we have an entirely new power
unit.
"From the outset we have always
held to the inherent advantages of the
V-type engine. 1t has a short. rigid
crankshaft. 1t is compact. 1t leaves
more room on the chassis for the body.
"For many years past Cadillac has
been able to produce smoothly-per
forming engine by the most careful
machining of all moving parts to the
closest limits of precision, and by
carefully balancing the rotating and
the reciprpcating parts. !,
"Over period of ten years We had
developed a clientele educated to ex-
Meeting unusually smooth perform
ance. Many of them had been driving
Cadillac cars since we first introduced
the V-type engine back in 1919. 10
give this discriminating clientele ao-
solutely the best in performance we
started out several years ago with re-
newed energy to solve a problem in en-
eine balance which had long been con-
sidered commercially unsolvabieT
Engine Same Size.
1--WE realized that the successful ap-
plication of this principle was the
greatest accomplishment in V.type en-,
zine design since its introduction: and
our slogan, "expect great things" had
really been the keynote of a certain
norton of our engineering endeavor
over a period Of years.
ain addition to this great forward
step in smoothness of operation: refine
ments of the engine since 1915 have
added greatly to its power. The engine
is exactly the same size. as IN ioIo.
No fundamental dimension has been
changed. The bore and stroke are the
same. Yet we have increased the en-
zine power 20 per cent. besides get,
ting a performance which has proved
a revelation to those who have ridden
