BIC FACTOR

Modern European engineering, as
introduced to America In the Over
land Whippet. will work a change
in the general acceptance Of motor
power. Already the term activity
factor" Is being used by engineers
to describe the performance posi-
bility of the new type motor cars.
With the older type Of engineer
ing the rated horsepower was &C.
copied as the basis for comparison.
In the Whippet the developed horse.
power il 100 per cent greater than
the rated horsepower.
Such a difference in the indicated
power as compared with the realized
power has never before been shown
in the light car. field in this coun-
try. It has been common in Eng.
land and on the Continent for sew.
eral years.
Innovations in the four-cylinder
motor as built for light cars, and
shown in the Overland Whippet. in.
ciude such features as extra long
cylinder walls to keep the pistons
from sliding below the lower edge
Of the walls at the bottom Of tho
down stroke, the use OF full bond
bearings which eliminate the use
Of shims. extra heavy construction
in the crank shaft and in the cam
shaft. four-point suspension in the
motor and equally distinctive ele-
ments Of design in other parts.
The same excess of developed
power over rated power is brought
ABOUT by European principles in the
IlNra ~ lN~Ia
car which develops a full SO horse
power from motor dimensions which
are usually associated with consid.
erably less power than this. It
presents the best achievements in
modern engineering as worked out
Tor the Knight sleeve-valve motor.
The Overland Six and the WHY'S
knight Cheat Six show equivalent
advantages in engineering through
the use OF modern engineering. In
actual results so far as owaerg ars
concerned. greater mileage to the
gallon of fuel, greater acce,eration,
faster speed over the road, longer
life to the motor parts. are the dis.
tinguishirR features Of modern en-
Rineering
In the chassis. the strength Of
the reinforcing members. the depth
OF the channel in the frame, the
efficiency Of the four-wheel brakes.
and the carrying Of the weight OF
the car close to the ground are
prominent features Of modern en-.
cheering
None Of the features Of design
which ara included in the modern.
iZtng Of motor car construction are
nntried. They have all been proved
in the hardest kind of usage.
Tho high developed horsepower
In relation to the rated power has
been proved in the racing cars
which. with 91.5 cubic inches of pis,
ton disbursement, have achieved
speed. 1t Is demonstrated every day
fhour. It has been proved in the
Tiny italian motor which turns over
at 1oO0 revolutions per minute and
envelopes enormous power at this
epeed. It is demonstrated every day
in the English cars which, with r.
rated power Of from ZIP. to Is HIP.
show q develoned power of from
16 HIP. to 80 HIP.
The en-. ire trend among motor
car manufacturers is along the lines
OF modern engineering. A study Of
the cars which are popular today
indicates modern engineering to q
certain degree. The products of
WHY'S Overland, which have beer
completely designed along the lines
Q: modern engineering constitute
the first complete line Of thorough
~ modernized cars yet to be pro.
