One resource that did not appear on the books of General Motors or on the rolls of the occupying authorities was most responsible for the recovery of Opel in 1945, the collaborative nature of its workers. They were not itinerant hires who had looked on their work at Rüsselsheim as just another job. They were men and women who had, for the most part, come from that immediate area, many from the country, and had literally grown up with the Adam Opel AG. The fate of Opel was important to its workers, for its collapse would mean the loss of the most important employer for the people of Rüsselsheim, who were finding their way home from the chaos of war.
Historically, Opel vehicles have also been sold at various times in the North American market as either heavily modified, or "badge-engineered" models under the Chevrolet, Buick, Pontiac, Saturn, and Cadillac brands - for instance the J-body platform, which was largely developed by Opel - was the basis of North American models such as the Chevrolet Cavalier and Cadillac Cimarron. Below is a list of current or recent Opel models which are sold under GM's North American brands.
The Corsa C was introduced with a 1.7 L DTI Ecotec turbodiesel engine supplied by Isuzu (Circle L) with 75 hp (55 kW). This was later joined by the 1.7 L DI Ecotec turbodiesel engine also supplied by Isuzu. The 1.7 L DI Ecotec did not include an intercooler and this reduced power to 65 PS (48 kW). From 2003, a new 1.3 L CDTI Ecotec turbodiesel engine was supplied by Fiat (MultiJet) which produced 70 PS (51 kW) and a 1.7 L CDTI Ecotec turbodiesel was supplied by Isuzu which produced 100 PS (74 kW). This new 1.7 L CDTI Ecotec featured a variable geometry turbocharger.
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.
