In 1935 the time was ripe for the people’s car – from Opel, mind you. The P4 presented in November rolled of the assembly line soon thereafter. The four-seater with four-cylinder four-stroke engine – according to the P4 brochure “like the most expensive cars in the world” – cost only 1,450 Marks in the standard version. “How is this possible? To offer so much value, a real full-out automobile that even exceeds expectations for so little money?” The answer was clear: thanks to state-of-the-art mass production. This also came into play shortly thereafter with the Kadett 1, which also took over the design of the Opel Olympia. This made it one of the first German cars to feature a self-supporting all-steel body, which was more comfortable, safer and more durable than the conventional frame structures.
The Kadett B wis sauld in the Unitit States throu Buick dealers frae 1967 till 1972 simply as the Opel. U.S. models wur later grantit the front end an trim o the new Opel Olympia, introduced in 1966 as an upmarket version o the Kadett. The caur teuk pairt in the Trans-Am Series durin its commercial life. Kadett A an B wur technically semple caurs whose task wis tae compete wi the mercat leader, the Volkswagen Beetle.
A mark of General Motors' confidence in their plans for the small car sector, and something that the Opel Kadett and the Vauxhall Viva had in common, was that the manufacturer built for each new model a completely new car plant in a region characterized by relatively high unemployment and the availability of a skilled workforce, but with no strong tradition of volume auto-making. The Vauxhall Viva was the first car built at Vauxhall's Ellesmere Port plant while the Kadett A was the first product of Opel's new purpose built Bochum plant. Ellesmere Port and Bochum would effectively become sister plants, producing subsequent generations of Kadett as well as their Vauxhall badged sisters (the Chevette and Astra) for the next fifty years.
A third body was also produced for use in flexibility tests. In the summer of 1994, the Calibra received a light facelift. Most noticeably, the manufacturer badge migrated from its place atop the leading edge of the bonnet into the front grille. Throughout the production run, several special models were launched. In the United Kingdom, this began with the 'Tickford' conversion in October 1991, however only 26 Calibra's were ever converted.
Using a gear-driven system, power was taken from the 6-speed sequential gearbox forward to the half-shafts, which appeared to embrace the raucous 54 degree V6. By doing this Opel had cleverly avoided a nose-heavy car, giving them a significant handling advantage. Weighing in at 1040 kg (2292 lbs)m the car looked like a serious challenger for Alfa Romeo.
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.
