This range of engines was also used for later models of the Corsa/Nova, and the mid-sized Cavalier/Ascona. From May 1981, the 1.3 was also available with a three-speed automatic. The automatic was made available to the diesel in September 1982. One interesting version which first appeared in mid-1982 was the Kadett Pirsch, (for deer stalking, a stealthy form of hunting). In non-German-speaking countries it was generally marketed as the Kadett Off Road. This was a station wagon with rustic trim, fitted with a differential brake, reinforced suspension and more suitable tires, increased ground clearance, a skid plate, and shortened front fenders. In Sweden, a special postal Kadett ("Opel Kadett Post") was offered, fitted with a high roof (necessitating a unique and much taller windshield) and a sliding right-hand door, RHD, and the automatic transmission. This version was converted by Karosseriefabrik Voll (in German) in Würzburg, Germany. Voll also made a postal version of the Kadett E.
As such, the car’s 2.5L C25XE V6 was turned around 90 degrees to assume a longitudinal position. Keeping only the most essential bits, British engineering firm Cosworth turned the 170 horsepower engine into a large bore, short stroke masterpiece. Using design principles akin to those used in Formula One, the unit belted out 420 horsepower at 11,650 rpm.

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.
