During the 1930s, the Rüsselsheim plant was never given a major role in Germany's war preparations. Neither was Ford's plant in Cologne considered trustworthy enough for a big assignment, such as tank manufacture, in view of their earlier foreign associations. Initially, of course, the war was thought to be a short one settled in Germany's favour. Auto plants were shut down, to conserve resources, but not converted to other jobs. As was common with much of the production in Nazi Germany during the war, slave labor of deported civilians and Soviet POWs was utilized in the Opel factories.
The Kadett A (above) finally appeared in 1962, and was a classic GM/Opel effort: highly pragmatic, conventional in every respect, reasonably stylish for its time, and designed to deliver a good bang for the buck. In just about every way possible, it was the antithesis of the VW: front-engine rwd, a rather tinny but roomy body, highly tossable but with a primitive suspension and ride, a very roomy trunk, and excellent visibility as well as economy. Oh, and a proper heater even! Its little 987 cc OHV four made 40 net/46 gross hp, six more than the VW 1200. Its trim fighting weight of 1475 lbs (670 kg), some two hundred pounds less than the VW, showed in both its acceleration and body integrity.
