that Of q new car even when the
vehicle may register an aggregate
mileage of more than $4,000.
Is it because of the care these
vehicles have had that this appealing
virtue endures?
It is not. Rather it is because even
the least expensive cars today are so
designed and so built that far beyond
what formerly was the limits OF their
smoothly and quietly.
To the welding process, technical
and dull sounding though it may be,
the motoring public is indebted to
FARCE extent for this particular quality
in its latest automobiles Instead of
the erstWhile arrangement of innu-
merable bolts, nuts, screws and rivets
to hold various parts together, the
factory now resorts to Welding.
Just how extensively this process is
used is illustrated in some figures re-
Gently announced by one of the larg-
est passenger car manufacturers. In
the company's two-door sedan model,
q total of 3,415 YIELDS are utilized in
the process Of producing the complete
body and chassis of the car.
Such is the intensity with which
this process is being developed that
tomorrow the number may be even
greater.
Engineers point out that four ma
3or purposes are served by the prac-
tice:
First, welding makes the Joined
parts into one solid whole, obviating
the chance Of loosening or separating
with accompanying squeaks, rattles
and rapid wear-the latter invariably
productive Of still greater noise.
Second, Welding permits Of a ma
terial reduction in weight-a very
considerable element in the modern
cars performance, since any cars
speed, aceeleration and climbing
ability are the product of its weight
power ratio.
Third, production costs are reduced.
Fourth, there is an assurance of
uniformity of workmanship since the
machinery used in welding Is entirely
automatic in operation.
Looking at the new cars, have you
been struck with the fact that the
coach model, or tyo-door sedan, ap-
pears to be waking a comeback?
That is precisely what is happening.
This former Leaders in popularity
which a few years ago surrendered
% Eyo-
passenger closed model is showing
definite signs of challenging again for
supremacy.
It is not just a matter Of economy,
either. Even in the upper price
classes where the relatively small
price differential is less Of factor,
the two-door, e-paSsenger car is
increasing in popularity. To be sure,
it is not called a coach in every case
these days, but don't be misled by the
new designation, touring sedan" now
generally used.
It's the old coach and one of the
industry's greatest style enthusiasts
thus explains the revival in its popu-
larity:
"It goes without saying that people
feel safer at high speeds in two-door
sedan than they do in any other five
passenger type, especially if there are
children in the back seat There al
ways is the possibility that they will
tamper with the rear door handles
and locks and cause the doors to fly
open, which, of course, is extremely
dangerous at almost any speed
LAS far as all-around convenience
goes, the two-door body type fills the
bill better than most other types.
However, until the present series of
cars came along there were always
certain drawbacks from the stand
point of appearance and interior ar
rangement.
Nov, streamlining has given to
these cars an overall appearance that
could not be achieved in the older
body designs. Many discriminating
motorists contend that the two-door
touring sedan is the best-looking car
IN the entire line.
Then, too, the more comfortable
arrangement and the improved ap-
verified many to this body style.
"One thing that has struck the
popular fancy in the two-door touring
sedan model as much as anything, no
doubt, is the manner In which the
body designers have provided for a
large, commodious trunk without sac
rificing room or comfort in the rear
seat"
Automobile engineers and technical
experts OF the oil companies cannot
agree on what constitutes real oiliness
in automobile engine lubricants.
Recently summary of the points
at issue was made by B. e. Sibley, q
member of the Contest Board of the
American Automobile Association, and
also chief technologist for one Of the
large oil companies. Sibley has made
q study of the oiliness problem, with
particular reference to relationship to
rev types Of bearings with which au-
tomobile power plants have been
equipped during the past year.
Engines of today, he points out,
are capable Of much higher perform
ance than those manufactured a few
years ago. In the case Of the auto
mobile engine. much more is de-
manded than in the past. This in
wolves both design features and lubri-
cants used in the machine. Added
70 that are the factors of improve
xnent in roads and the increase in
continuous motor operation or longer
operation at higher speeds.
In the past. bearing dimensions
we're larger. Engine speed and &C
celeration features also have changed,
hence bearing pressure has increased
considerably. The ever-present de-
mand for more power, better accel-
Grafton and improved performance
provides a problem for the designers,
who have to get more power from
the same overall dimensions or even
less space, hence they have to fight
