Pobeda poses beside a 1956 American car.
Body workmanship on Pobeda was rougher
than that on the American car, with signs
of handwork. But Pobeda's chrome grille
work trim appeared to be of better quality.
qem ae RUSSIAN.Pobeda
Compares with American Cars
and What It Reveals About Russian Know-How
ANY attempt to measure the strength of
Russia's red heart should start with an
examination of the sinews-the products
which reveal Russia's ability to compete as an
industrial-nation.
This Pobeda, is one such product. Not a "show-
piece" jet plane or secret missile, it's true. It is,
however, a piece of everyday transportation that
Russia has manufactured for years in some
quantity. As such, it should show us whether
the Russians really know how to design and
build a good automobile.
When compared with current American auto-
motive standards, this 1956 car leaves a lot to be
desired. By Russian standards, however, the Po-
bedn does a job, and does it well.
ted Copycats. Is that a credit to the designing
ability of Russian engineers? Well, they seem to
know how to copy what they want. From its
styling skin to its mechanical core, the Pobeda

~a 10'to"15 year old Plymouth, Ford, Chevrolet,
and Nash, blend them together in your mind's
eye, and you'll have something that looks like
a Pobeda. -
Or dig a bit deeper. Open the hood or put this
Pobeda up on a lift rack, and you'll find: a Jeep-
like engine turned end for end with the car-
buretor on the right side; a rear end similar to
that on a Model A Ford; a front end that also
looks like a Jeep's; a transmission that might be
a modified copy of a 1932 Model B Ford trans-
mission. With enough time (and enough junk-
yards) you could probably locate the original
versions from which Soviet engineers copied all

Frozen Models. Nor did the Russians, once they
decided to copy our immediate pre- and post-
war cars, bother with a yearly model change.
The 1946 Pobeda is almost a twin brother to the
1956 Pobeda, not only in styling, but also in en-
gine and body specifications.

Russians obtain from this sampling of old de-
signs. You'll note that the Pobeda is a placid
plodder with very little get-up-and-go, yet with
somewhat better fuel mileage than our 1957
models.
Clearly, this middle-price range Russian car,

ing customers in the free American
market. But for the Russian market
(and those captive . satellite markets
tied to Russia with apron strings of
steel), the Pobeda is just what the
Kremlin ordered. It is a sturdy piece

speed operation over rough roads.

this particular problem. (But they
would have others, as we shall see.)
There is a remarkably elaborate

vented into the carburetor intake

real justification for such an elaborate system
would be the dusty roads of Russia. By venting
the oil filler pipe and tappet cover plate back
into the carb intake, crankcase breathing is es-
sentially sealed off from incoming dust and dirt
that would increase engine wear.

it also shortens warm-up time. The fact
is, a lot of U.S. car owners might like
to see this old idea make a comeback
on American cars. .
The short two-member frame under
the engine has three cross members,
with an all steel, semi-unit type body
serving as a carrier with several cross
panels beneath it. Additional enclosing
panels are used around such compo-,
nents as the parking brake system. You
don't get much racking with such
body construction, but the sympathetic
vibrations of 'all these panels at speeds of 37
mph (60 KPH) and up, is enough to give anyone
a headache. Drive slowly, though, and you'll find
the ride relatively serene, no matter how rough
the road surface.
Springing is rugged, too, with heavy coils in
front and massive, but flexible, rear leaf springs
covered with rubberized fabric boots (Fig. 3).

ties (service stations are 70 to 100 miles apart in
most of Russia, and the scarce replacement parts
can only be obtained with official permission).
Mud Hooks.- The Pobeda has two frame-
mounted towing rings for hauling you out of the
mud (Fig. 6). Behind the grille and-in front of
the radiator are louvers -(like the old Pines Win-
terfront!), which can be opened or shut from the
driver's seat. Not only should that help the Po-
beda stand off the severe Russian winters, but
