A convertible version was also available, for the first time in 1987, built by Bertone of Torino/Italy, bringing it to line with competitors, such as the Ford Escort and Volkswagen Golf. For the 1988 model, capacities were raised from 1.3 to 1.4 litres. In the fall of 1986 a new 1,998 cc engine replaced the 1.8 hitherto used on the GSi and Vauxhall Astra GTE in many markets, although the 1.8 continued to be sold in some places. In 1988, a 16-valve twin-cam version was developed for a high-performance GSi/GTE model, yielding 156 PS (115 kW) in non-catalyzed form, six less horsepower with a catalytic converter fitted. While criticized for a lack of refinement, the GSi 16V was also lauded as the most powerful car available in its class at the time. Aside from the "16V" badging, it could be told from an eight-valve GSi by its twin rectangular exhaust pipes.
Announced in November 1947, production of the postwar Olympia, with austere painted hubcaps, began in December 1948 and allowed a modest return to export sales in that year. In October 1948, the Kapitän came back to the Opel line-up, unchanged except for such details as the shape of the headlights and improvements in the leaf springs and dampers. Prices in 1948 were 9950 DM for the Kapitän and 6,785 DM for the Olympia (the Deutschmark having replaced the Reichsmark on 20 June 1948).
Technically, Calibra was closely related to the first generation Opel Vectra. It was styled by General Motor's designer Wayne Cherry and German designer Erhard Schnell. The Calibra united exciting design with optimized aerodynamics and everyday practicality. The wide-opening tailgate gave easy access to a versatile, 980-liter luggage compartment. Generous standard equipment included power steering, a five-speed close-ration gearbox, a six-speaker audio system and tinted windows. Air conditioning, a four-speed automatic transmission and an electric tilt/slide sunroof were among the options.
The Kadett C was introduced in Brazil as the Chevrolet Chevette. The three-door station wagon was called the Chevrolet Marajó, and a pick-up was named Chevy 500. Brazilian production commenced in 1973, with the Marajó being added in 1980 and the Chevy 500 in 1983, shortly after a significant facelift affected the entire line. Brazilian cars had engines in various combinations of size - 1.0 (1992-1993), 1.4 (1973-1982), or 1.6 (1982-1995) liters - and fuels (gasoline or ethanol), though not all combinations were available for all body configurations. The last Marajó was built in 1989, the last Chevette in 1993, and the last Chevy 500 in 1995.
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.
