The Insignia flagship followed exactly the same initiative as the Astra. Once again the Opel engineers’ main objective was efficiency. Thanks to optimized packaging and lightweight materials they could save up to 175kg on the Insignia Grand Sport compared with its predecessor – much to the benefit of dynamics and fuel consumption. Depending on powertrain and equipment, the current Insignia Sports Tourer even weighs up to 200kg less than the similar model variant from the first generation.
The Kadett D wis introduced in November 1979, goin on sale in the UK some five months afore the Breetish version, the Vauxhall Astra Mark 1, wis launcht in Aprile 1980. Aw models wur designed as three- or five-door hatchbacks an estates or station wagons. Thare wur an aa twa- an fower-door sedans, which uised the same bodyshells as the hatchbacks, but thir wur suin dropped. An aa dropt, in comparison tae the C Modell wis the Coupé.
That makes it a similar size and weight to the outgoing Corsa, at a whiff over four metres long and 1177kg. Beyond that, new means new. Every panel on the mildly Adam-ised, slightly more butch exterior is different. Every component forward of the A-pillars is new. Every suspension component, too, as are the pick-up points for the front MacPherson struts and the rear torsion beam.
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.
