Other events which would powerfully affect Opel's future were taking place in 1948. In February and March, a GM study group came to Germany to investigate every aspect of Europe's economic situation and Opel's special problems. On their return, they submitted a report on 26 March recommending that General Motors resume control of Opel. On 5 April, however, GM's financial policy committee concluded, "in view of the many uncertainties surrounding the operation of this property, the Corporation is not justified in resuming the responsibility for its operation at this time..." GM, it seemed, did not want Opel.
Throughout the production run, several special edition models were launched. Customers who chose a Calibra Cliff Motorsport Edition in May 1996 were way ahead of the game. Its paintwork was the same as the Class 1 racing car in which Manuel Reuter would win the ITC championship for Opel at the end of the season. The street-legal Cliff racer had a 20 mm lower sports chassis and BBS light alloy wheels (7J x 16).
Launched in 1962, GM Europe's small car for the 1960s, the Opel Kadett, looked like a shrunk Chevy Nova, and hid a 1.0-liter water-cooled overhead-valve four-cylinder up its nose. While this motor had pre-War origins, it was a good one. It weighed just 211 lbs, revved beyond 6000 rpm, and made 54 horsepower in the high-compression 'S' version, as long as you used premium fuel.
The brakes were now controlled using a hydraulic mechanism. The suspension featured synchromous 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 light-weight cars such as the Kadett. By the end of 1937 33,402 of these first generation Kadetts had been produced.
The Opel Kadett D was also built in South Africa by General Motors South African (Pty) Ltd. The South African range was made up of four-door fastback sedans, five-door hatchbacks, and a five-door estate model called the Voyage. The engines used are Opel's 1.2 litre overhead valve inline-four (L models only), or the OHC 1.3 liter (GL, GLS, and Voyage). Power is 60 PS (44 kW) and 75 PS (55 kW) respectively. Later a 1.6 liter was added and also a 1.8 in the GTE performance model.
1 = Optional on SC / SE - late 2017. Automatic Emergency Braking with Pedestrian Detection works automatically at speeds between 5 and 140km/h. For speeds between 5 and 30km/h a 0.9g deceleration is applied to reduce the impact speed of the collision. For speeds of 30 to 140km/h the system reduces the speed by up to 50km/h. To reduce speed by over 50km/h the driver needs to provide additional braking. The operational speed range depends on the type of obstacle detected:

The Opel Kadett was reintroduced by Opel in 1962, with deliveries beginning on 2 October, a little more than 22 years after the original model was discontinued in May 1940. Like the original Kadett, the new car (designated the "Kadett A") was a small family car, although it was now available in 2-door saloon, 3-door Car-A-Van (estate) and coupé versions.
