In the US, some 500 Buick dealers started carrying the Kadett in 1964, after their previous sole product, the larger Rekord, was knocked out of the ring by GM’s own 1960/1961 compacts. I strongly suspect the Buick dealers (and their ad agency) who hadn’t yet taken down their Opel signs were not really very committed or motivated, and all of 17k ’64s and 14k ’65 Kadett A were sold. Meanwhile, VW was moving some 400k Beetles in America.
Many Opel models or models based on Opel architectures have been sold in Australia and New Zealand under the Holden marque, such as the Holden Barina (1994-2005), which were rebadged versions of the Opel Corsa, the Holden Astra. a version of the Opel Astra, and the Captiva 5, a version of the Opel Antara. In New Zealand, the Opel Kadett and Ascona were sold as niche models by General Motors New Zealand in the 1980s, while the Opel brand was used on the Opel Vectra until 1994.
The Corsa C was introduced with a 1.7 L DTI Ecotec turbodiesel engine supplied by Isuzu (Circle L) with 75 hp (55 kW). This was later joined by the 1.7 L DI Ecotec turbodiesel engine also supplied by Isuzu. The 1.7 L DI Ecotec did not include an intercooler and this reduced power to 65 PS (48 kW). From 2003, a new 1.3 L CDTI Ecotec turbodiesel engine was supplied by Fiat (MultiJet) which produced 70 PS (51 kW) and a 1.7 L CDTI Ecotec turbodiesel was supplied by Isuzu which produced 100 PS (74 kW). This new 1.7 L CDTI Ecotec featured a variable geometry turbocharger.
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).
Later, an 1800 cc version wis introduced for the Kadett/Astra GTE model. This range o ingines wis an aa uised for later models o the Corsa/Nova, an the mid-sized Cavalier/Ascona. The Kadett D wis an' a' equipped wi a 1600 cc diesel ingine that wis possible tae drive as cheap as 5.0 L/100 km, an a cairy-ower 1196cc OHV ingine. It wis an aa produced as IDA Kadett in Kikinda, Yugoslavie.
