This new category, Group A, featured very stringent homologation requirements. In order to qualify for competition, the competing model needed to be produced at least 25,000 times. Furthermore, the FIA required ten percent of these cars to be a specialty model, with another 500 allowed as “Evolution” models. If the 25,000 car limit had not yet been met, the new model had to attain a production number of at least 5000 units a year.
Not only was the body a bit bigger, but the Kadett B also had a slightly enlarged 1100 cc engine. This was externally a very compact motor indeed, and looked rather lost in the Kadett’s Kavernous engine bay. Power output increased correspondingly; there were 45 and 55 DIN hp (high compression) versions for Europe; the weaker on was sent stateside with a 54 (gross) hp rating.
The Opel Eye front camera processes diverse data, thus forming the basis for the driver assistance systems such as Speed Sign Recognition and Lane Departure Warning. If the system registers that the lane is being left unintentionally it warns the driver by emitting audible and visible signals. Cruise control with speed limiter also makes driving more pleasant. Forward collision alert with pedestrian detection and Automatic Emergency Braking helps avoid accidents, and it is combined with a special Driver Drowsiness Alert.
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.
