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.
Opel also produced the first mass-production vehicle in Germany with a self-supporting ("unibody") all-steel body, closely following the 1934 Citroën Traction Avant. This was one of the most important innovations in automotive history. They called the car, launched in 1935, the Olympia. With its small weight and aerodynamics came an improvement in both performance and fuel consumption. Opel received a patent on this technology.

The Kadett E has been seen as a grey import in the United Kingdom, but it is quite rare compared to its badge engineered sister, the Vauxhall Astra Mk II. It was never officially sold in Britain, and by 1989, General Motors was only marketing the Vauxhall brand in the United Kingdom, although Astras assembled at Vauxhall's Ellesmere Port plant were exported to the rest of Europe badged as Opel Kadetts. There was also a van version with a raised roof, called the Opel Kadett Combo.
In 2007, Opel introduced sport version of Corsa tuned by Opel Performance Center (OPC) – Corsa OPC. Corsa have 1.6 litre I4 turbo engine with 141 kW (192 PS; 189 hp) at 5.850 rpm and 230 N⋅m (170 lb⋅ft) of torque at 1,980 to 5,850 rpm, with overboost function which boost up torque figure to 266 N⋅m (196 lb⋅ft). 0 to 100 km/h (62 mph) time is 7.2 s and top speed is 225 km/h (140 mph). Differences with standard Corsa in interior are sporty Recaro seats, OPC steering wheel and gear knob, instrument dials with OPC background.
The basic trim level was called just the Corsa, which was followed by the Corsa Luxus, Corsa Berlina and the sporty Corsa SR. The SR receives a spoiler which surrounds the rear window, alloy wheels, checkered sport seats, and a somewhat more powerful 70 PS (51 kW) engine. Six years later, the Corsa received a facelift, which included a new front fascia and some other minor changes. The models were called LS, GL, GLS and GT.
Production started on December 4, 1946. The Moskvitch 400/420 continued to be made in Moscow with some minor changes until 1956, when it was replaced by the Moskvitch 402. The latter was an all-new design apart from the engine, for which Moskvitch continued to use the Kadett side-valve engine until 1958, when it was replaced with a domestically designed OHV engine.
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.
