The car was roughly the same size as the dreaded Audi V8, but lacked the power and four wheel drive traction to keep up. Owing to Group A’s strict homologation rules, Opel had no way of bringing the car up to speed without building a dramatically expensive road car as well. In the much looser environment offered by FIA Class 1 however, this was no longer an issue.
In 1957 Opel Product Director Karl Stief wis mandatit bi General Motors headquarters in Detroit tae develop "the perfect Anti-Volkswagen" ("einen perfekten Anti-VW"). The development team wis heidit up bi Stief, supportit bi Hans Mersheimer (caur-body) an Werner K. Strobel (ingine an runnin gear), unner conditions o sic secrecy that even nou vera little is kent o the development history o the 1962 Kadett. 649,512 o caurs haed been biggit at the company's new Bochum factory bi the time it wis replaced in Julie 1965.
While the Ipanema clearly succeeded the Marajó, production of the Chevette (by now in sedan form only, the hatchback having been discontinued after the 1987 model year) and of the Kadett noticeably overlapped; the newer model was placed above the old one in Chevrolet's lineup. While Chevrolet entertained the possibility of a pick-up version of the Kadett E, it never materialized.
In the early 1920s, Opel became the first German car manufacturer to incorporate a mass-production assembly line in the building of their automobiles. In 1924, they used their assembly line to produce a new open two-seater called the Laubfrosch (Tree frog). The Laubfrosch was finished exclusively in green lacquer. The car sold for an expensive 3,900 marks (expensive considering the less expensive manufacturing process), but by the 1930s, this type of vehicle would cost a mere 1,930 marks – due in part to the assembly line, but also due to the skyrocketing demand for cars. Adam Opel led the way for motorised transportation to become not just a means for the rich, but also a reliable way for people of all classes to travel.
By the 1970s, Opel had emerged as the stronger of GM's two European brands; Vauxhall was the third-best selling brand in Great Britain after the British Motor Corporation (later British Leyland) but made only a modest impact elsewhere. The two companies were direct competitors outside of each other's respective home markets, but mirroring Ford's decision to merge its British and German subsidiaries in the late 1960s, GM followed the same precedent. Opel and Vauxhall had loosely collaborated before, but serious efforts to merge the two companies' operations and product families into one did not start until the 1970s - which had Vauxhall's complete product line replaced by vehicles built on Opel-based platforms - the only exception to the rule being the Bedford CF panel van, the only solely Vauxhall design which was marketed as an Opel on the Continent. By the turn of the 1980s, the two brands were in effect, one and the same.
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.
