The Corsa D was created using a new version of the SCCS platform, which was co developed by General Motors/Opel and Fiat, and is also employed by the 2006 Fiat Grande Punto. The first official pictures of the Corsa D, were released by Opel in May 2006. In the United Kingdom, What Car? awarded it 2007 Car of the Year. The Corsa D placed second in the European Car of the Year for 2006, only behind the Ford S-Max.
In March 2017, Groupe PSA agreed to buy Opel, its British sister brand Vauxhall and their European auto lending business from General Motors for US$2.2 billion. In return, General Motors will pay PSA US$3.2 billion for future European pension obligations and keep managing US$9.8 billion worth of plans for existing retirees. Furthermore, GM is responsible for paying about US$400 million annually for 15 years to fund the existing Great Britain and Germany pension plans.
In marketing terms the "Kadett KJ38" was intended to fill the niche that Opel had recently vacated with the departure of the Opel P4, but the KJ38, priced at 1,800 Marks, was more expensive than the P4 and its reduced specification left it with the image of a car for poor people (..Image des Arme-Leute-Autos..) at a time when economic growth in Germany was finally fostering a less minimalist approach to car buying. The "Kadett K38 Spezial" fared better in the market place: in 1938 and again in 1939 it was Germany's top selling small car. By May 1941 the company had produced 17,871 "Kadett KJ38"s and 56,335 "Kadett K38 Spezial"s.
As the war progressed, military authorities placed greater stress on the development of air-cooled engines, which they felt had more immunity to damage from weather, shellfire, and misuse. To meet this demand, Opel engineers developed an unusual variation on normal cooling for the 3.6 L truck engine. It was called "air-oil cooling", and used engine oil to take heat away from the jackets around the cylinder barrels. The heads were directly cooled by air, there being three separate aluminium finned heads, each serving two cylinders. Of this interesting engine, which developed 72 hp (54 kW; 73 PS) at 3,000 rpm on 74-octane fuel, only three examples were built.
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
