              Illustrating What High werReayMeans
Few things are more confusing to the motor car buyer than
the term "horse-power." The confusion is due to the fact that
there are two common ways of figuring it.
The method used for license purposes is the S. A. E. rating
and consists of multiplying the cylinder diameter first by itself,
and then by the number of cylinders. The
SAc l product is divided by two and one-half to
Horse- get the so-called S. A.E.horse-power rating,
P o er On this basis the "horse-power" of the
-Re - Reo-and of practically all six-cylinder
cars- is about 25. This figure has no
meaning whatever to the car owner as far
-S.A.E as actual motor power is concerned.
Horse In fact, the work of power engineers at oe Ppresent is focussed on diminishing the
of S. A. E. rating of motors while increasing
the actual horse-power.
This is true not only of automobile
motors for the public, but of special rac-ing
motors as well.
The Real Horse-Power

speeds, and widely varying power for
motors of similar size but different con-struction.
The real horse-power of the
Reo at the customary touring speed is
more than twice its S. A. E. rating.
Special Reo engineering features, such
as the giant intake valves, make its power
much higher than its size would indicate.

They are in-head valves, so
large that they give their cylin-ders
a full draught of gas prac-tically
instantaneously.

As a rule, six-cylinder motors have

to have the carbon cleaned out and the
valves ground every 4,000 miles. The average Reo owner
seldom has to do anything at all about carbon short of 10,000
or 12,000 miles. And even then there is very little to do.
Service costs of $25 fot 25,000 miles
Service costs of $25 for 25,000 miles are commonly reported
by,Reo owners in Chicago. This condition bears a direct rela-tion
to the high resale price of Reo used cars.
Reo owners are so well satisfied with their purchases that
very few used Reo cars are ever offered for sale. When they
are offered, they command an exceptionally high price.
A few days ago a Reo owner asked us to sell for him his Reo
Coupe which he had run 19,000 miles, because he wanted a
Reo Sedan. It was sold in a day for only 15% less than he paid
for it. The total depreciation for him amounted to less than is
generally figured on the average new
car that has been run 500 miles.

ANewWinter and Summer Model
for I535
The 1924 Coach.Touring Reo with
its enclosed body, as illustrated, built
by a Chicago maker of fine coach
bodies, provides four-door conven-ience,
thoroughly balanced closed
car construction, and the rigidity es-sential
to luxurious silence-for$1535.
The problems that have troubled
other coach-makers have been solved
in the Coach-Touring Reo by design-ing
the frame members on exception.

new knowledge of wood that airplane
construction has made available.
The top rails and back supports of
the coach unit must have unusual
strength and rigidity-they are there-fore
made of cabinet ash. The bows

are therefore made of kiln-cured pop-lar.
The liner ribs must stay as true
and flat as steel bands and yet be
lighter than any metal; they are there-fore
made of thoroughly-seasoned
and flaw-free white pine.
The acoustic lining of the top
must be sound-absorbing and rum-ble-

and unalterably smooth base for the
outer fabric; it is therefore made of

The outer fabric must withstand

The Reo Safety Creed
We believe that driving an automobile in the streets of
Chicago is a privilege and not a right.
We believe that like any other privilege it should be for-feited
if it is abused.
We believe that everyone, whether car owner or hired
driver, who repeatedly drives at dangerous speeds should
have his privilege forfeited.
We believe that everyone, whether car owner or hired
driver, who passes street cars in defiance of the lav should
have his privilege forfeited.
We believe that everyone, whether car owner or hired
driver, who drives an automobile while intoxicated should
have his privilege irrevocably forfeited.
We believe that if these manifest things are done, the num.
ber of automobile accidents in Chicago will be swiftly and
radically reduced.
