The 5-door Corsa was essentially the same car as the 3-door version with little differences to tell the two apart, except the extra set of doors, of course. Powered by an almost identical range of engines, the 5-door Corsas had a large wheelbase which lead to a trunk volume increase from 9.2 (for the 3-door) to 10 cubic feet. The GSi was not a level equipment to be found among the engine-milder ...
The Kadett C appeared in August 1973 and was Opel's version of the General Motors' "T-Car". It was the last small Opel to feature rear-wheel drive, and remained in production at Opel's Bochum plant until July 1979, by which time Opel had produced 1,701,076. Of these, 52% had been exported outside West Germany, most of them to markets in other parts of western Europe.
The Kadett’s role in facilitating that is a major piece of automotive history I’ve been wanting to tell for years, but finding a Kadett in this country has been impossible, despite Opel having dumped almost half a million on our shores. It took my son’s recent trip to the old country to find one, sitting on the street in Innsbruck, no less. Maybe folks back there have a greater appreciation for Kadetts and the role they played; Americans’ fling with the Kadett was a very fleeting one, and perhaps many would just as soon forget it. Not me.
The extra-light, all-aluminium engines, together with optimization of the front and rear axles, also contribute to the low total weight. The particularly compact three-cylinder petrol engines weigh around 15kg less than the previous generation of similarly powerful four-cylinder units. Highly unusual in the small-car-sector is the new Corsa’s aluminium engine bonnet, which although longer, saves 2.4kg in comparison to the previous model’s bonnet made of steel. The Insignia flagship was previously the only model in the Opel range with an aluminium bonnet. The seats also have been put on a diet. The new optimized seat structure saves a total of 10kg – 5.5kg at the front, 4.5kg at the rear. New lighter insulating material was used for fine tuning. Altogether the measures result in a weight reduction that, in combination with optimum aerodynamics and the efficient powertrains, will lead to a considerable reduction in fuel consumption and CO2 emissions.
