The Calibra, styled by the American head of GM design Europe, Wayne Cherry (retired), is considered by some the most stylish Vauxhall/Opel ever, but being based on the Vectra chassis its ride and handling were not significantly better than that of the family car from which it grew. It was, however, the most aerodynamically efficient Opel everwith a drag coefficient (Cd) of 0.26. It remained the most aerodynamic mass production car for the next 10 years, until the Honda Insight was launched in 1999 with a Cd of 0.25.
Opel (German pronunciation: [ˈoːpl̩]) is a German automobile manufacturer, a subsidiary of French automaker Groupe PSA since August 2017. From 1929 until 2017, Opel was owned by American automaker General Motors. Opel vehicles are sold in the United Kingdom under the Vauxhall brand. Some Opel vehicles are badge-engineered in Australasia under the Holden brand, and in North America and China under the Buick brand.
Within Opel the Calibra was a car with potential but sadly much of it was unrealised. Valmet Automotive in Finland, who had a manufacturing facility that build Calibras alongside the German plant, produced two handsome convertible prototypes that never saw production. A Saab coupe based on the Calibra was also rumoured but, again, never saw the light of day.
In addition to its West German home market, the Kadett A sold strongly in what were becoming the manufacturer's traditional export strongholds (notably in Benelux, Scandinavia, Austria and Switzerland). Between February 1964 and the Autumn/Fall of 1965 the cars were also exported to the United States where they were sold through approximately 500 Buick dealers. The same 993 cc engine was fitted and it is not clear whether it was differently tuned for North America: horsepower ratings were differently computed in the USA, following locally devised "SAE" rules: for American market purposes the maximum outputs for the engines were quoted as 46 hp (34 kW; 47 PS) and 54 hp (40 kW; 55 PS).
While the Ipanema clearly succeeded the Marajó, production of the Chevette (by now in sedan form only, the hatchback having been discontinued after the 1987 model year) and of the Kadett noticeably overlapped; the newer model was placed above the old one in Chevrolet's lineup. While Chevrolet entertained the possibility of a pick-up version of the Kadett E, it never materialized.
