The manufacturer now offered two versions of the Kadett, designated the "Kadett KJ38 and the "Kadett K38" the latter also being sold as the "Kadett Spezial". Mechanically and in terms of published performance there was little to differentiate the two, but the "Spezial" had a chrome stripe below the window line, and extra external body trim in other areas such as on the front grill. The interior of the "Spezial" was also better equipped. To the extent that the 300 Mark saving for buyers of the car reflected reduced production costs, the major difference was that the more basic "KJ38" lost the synchromous springing with which the car had been launched, and which continued to be fitted on the "Spezial". The base car instead reverted to traditional rigid axle based suspension similar to that fitted on the old Opel P4.
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.
The parent company PSA is also preparing the transition to the electric age: By 2025, the carmaker intends to offer offshoots with electric or hybrid drive for all 40 models of its brands. It will start in 2019 with all-electric versions of the Peugeot 208 (reservations opened in the UK last month) and the DS3 Crossback. An electric version of the Peugeot 2008 will follow in 2020. PSA’s plug-in hybrid offensive starts in 2019 with a corresponding offshoot of the DS7 Crossback, the PHEV versions of the Peugeot models 3008 and 5008, the Citroën C5 Aircross and the Grandland X mentioned above.
1 = Optional on SC / SE - late 2017. Automatic Emergency Braking with Pedestrian Detection works automatically at speeds between 5 and 140km/h. For speeds between 5 and 30km/h a 0.9g deceleration is applied to reduce the impact speed of the collision. For speeds of 30 to 140km/h the system reduces the speed by up to 50km/h. To reduce speed by over 50km/h the driver needs to provide additional braking. The operational speed range depends on the type of obstacle detected:
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.
