All Mexican previous versions were known as the Chevy, with the names Monza used on the saloon, and Swing (five-door) and Joy (three-door) for the hatchbacks, all with a 1.6-liter 78 PS (57 kW) four-cylinder. There was also a low-end three-door model called the Chevy Popular, which was equipped with a 52 PS (38 kW) 1.4-liter engine. The latter 2004 and 2008 redesigns were simply named Chevy and Chevy Sedán. The Chevy was a favourite among taxicab drivers and one of the best selling cars in the country.
In the US, the 1968 Kadett took on the Olympia’s grille and there were other changes too. The Olympia and the US Kadett now were available with the bigger “high-cam” four, in 1.5, 1.7 and 1.9 liter versions (no 1.7 for the US). This changed the performance equation considerably, especially in the new Rally 1900, which had a new fastback to go along with its big jump in power. The 1.9 was rated at 102 (gross) and 90 (DIN-net) hp, and there was nothing that could touch it in its class. This was the equivalent of dropping the big block V8s in the GM midsize cars, the German Chevelle SS 396.
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.
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.
The Kadett A (above) finally appeared in 1962, and was a classic GM/Opel effort: highly pragmatic, conventional in every respect, reasonably stylish for its time, and designed to deliver a good bang for the buck. In just about every way possible, it was the antithesis of the VW: front-engine rwd, a rather tinny but roomy body, highly tossable but with a primitive suspension and ride, a very roomy trunk, and excellent visibility as well as economy. Oh, and a proper heater even! Its little 987 cc OHV four made 40 net/46 gross hp, six more than the VW 1200. Its trim fighting weight of 1475 lbs (670 kg), some two hundred pounds less than the VW, showed in both its acceleration and body integrity.
