The Opel Kadett was a small family car produced by the German automobile manufacturer Opel between 1937 and 1940, and then again from 1962 until 1991 (Cabrio 1993), when it was replaced by the Opel Astra, (branded in the UK as the Vauxhall Astra MK3).
In 1992, GM Europe decided to standardise model names across its two brands, and Opel adopted Vauxhall's name for the Kadett, Astra, for the replacement car for Europe which debuted that year. Only in South Africa, the Kadett name continued on the first Opel Astra hatchback until 1999, when all models took the Astra name.
However, under Opel's internal naming convention, successive generations of the Astra platform are treated as a logical continuation of the Kadett lineage - hence the original 1992 Astra was designated Astra F in relation to the previous Kadett E - this convention has continued through to the current (2009) Astra J.
The new Kadett followed the innovative Opel Olympia in adopting a chassis-less monocoque construction, suggesting that like the Vauxhall 10 introduced in 1937 by Opel's English sister-company, the Opel Kadett was designed for high volume low cost production. Competitive pricing led to commercial success, and Kadetts continued to be produced during the early months of the war: by the time production was interrupted in 1940 following intensification of hostilities, 107,608 of these Opel Kadetts had come off the assembly line at Opel's Rüsselsheim plant, which had been the first major car plant in Germany to apply the assembly-line production techniques pioneered by Henry Ford.
