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 -is Iargel i "patter`"n'ed after=not so mtich ' our preserit?da'y cars=bu parts aril p"feces of cars we ma a years ago:If you want to compare styling; go to the nearest junkyard, search out ~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 but a of w parts of`this car and its accessories 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. Table A 9550 's the kind of performance the 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.

That's not very far from some of ga` s-ol n? the ratios our cars have in second gear, which TIis low octane requirement might indicate is a good ,gear to use on heavily rutted roads or that Russian oil refineries are geared to produce hills at slow speeds. The small size of the engine jet fuels for fighter and bomber aircraft, rather in relation to the car's weight also accounts for than high octane gasoline for high performance the high axle ratio used. automobiles (see the discussion on this point in There are other clues which confirm the fact the Tech Talk accompanying. this article). that this car is intended for operation under In contrast, most fuel production in the United States is high octane gasoline, produced in a cracking process. And this fuel cannot be used in our jet aircraft. In other words, the major effort of our refineries is geared for automobile, not jet air- craft production, and any sudden conversion to major wartime de- mands might take time that we could ill afford. If their fuel production effort is indeed geared for jet air- craft, the Russians would not have this particular problem. (But they would have others, as we shall see.) There is a remarkably elaborate crankcase scavenging system on the Pobeda, with both the sturdy oil filler pipe and the tappet cover plate vented into the carburetor intake (Fig. 2). This means that gas getting FUEL ECONOMY POBEDA HIfANt run AMERICAN CARS?

But the 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.

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). The Jeep-like front.end uses no spacers or shims, while we are doing more and more shimming on American models, to reduce initial produc- rugged conditions with few maintenance .facili- 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 American values.
