Opel Kadett

The Opel Kadett is a small family car produced by the German automobile manufacturer Opel from 1936 until 1940 and then from 1962 until 1991 (the Cabrio continued until 1993), when it was succeeded by the Opel Astra.

Originally, the Kadett was Opel's smallest model; however, as it grew in size with each generation (ultimately competing in the European C-segment), the Opel Corsa became GM/Opel's entry-level model.

The first Opel car to carry the Kadett name was presented to the public in December 1936 by Opel's commercial-technical director, Heinrich Nordhoff, who would in later decades become known for his leadership role in building up the Volkswagen company. Production was interrupted in 1940 by World War II.

The new Kadett followed the innovative Opel Olympia in adopting a chassis-less unibody 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.

For 1937 the Kadett was offered as a small and unpretentious two door "Limousine" (saloon) or, at the same list price of 2,100 ℛ︁ℳ︁, as a soft top "Cabrio-Limousine". The body resembled that of the existing larger Opel Olympia and its silhouette reflected the "streamlining" tendencies of the time. The 1,074 cc side-valve engine came from the 1935 Opel P4 and came with the same listed maximum power output of 23 PS (17 kW) at 3,400 rpm. The wheelbase, at 234 cm (92 in), was right between the little P4 and the larger Olympia. The "11234" nomenclature stands for the engine's displacement in deciliters (11) followed by the wheelbase in centimeters (234).

The brakes were now controlled using a hydraulic mechanism. The suspension featured synchronous springing, a suspension configuration already seen on the manufacturer's larger models and based on the Dubonnet system for which General Motors in France had purchased the license. The General Motors version, which had been further developed by Opel's North American parent, was intended to provide a soft ride, but there was some criticism that handling and road-holding were compromised, especially when the system was applied to small lightweight cars such as the Kadett. By the end of 1937 33,402 of these first-generation Kadetts had been produced.

From December 1937 a modified front grill identified an upgrade. The 1,074 cc Opel 23 PS (17 kW) engine and the 2,337 mm (92.0 in) wheelbase were unchanged, with few differences between the cars for 1937 and those for 1938.

The manufacturer now offered two versions of the Kadett, designated the "Kadett KJ38 and the "Kadett K38" the latter also being sold as the "Kadett Spezial". Mechanically and in terms of published performance there was little to differentiate the two, but the "Spezial" had a chrome stripe below the window line and extra external body trim in other areas such as on the front grill. The interior of the "Spezial" was also better equipped. To the extent that the 300 Mark saving for buyers of the car reflected reduced production costs, the major difference was that the more basic "KJ38" lost the synchromous springing with which the car had been launched, and which continued to be fitted on the "Spezial". The base car instead reverted to traditional rigid axle based suspension similar to that fitted on the old Opel P4.
