1966 wis the year that Opel opened thair new plant at Bochum, devotit exclusively tae Kadett production. Atween 1965 an 1973 Opel produced 2,691,300 Kadett Bs which maks this model ane o the maist successfu Opels tae date in terms o sales volume. The Kadett benefittit on the domestic mercat frae a progressive slowin o demand for the auld Volkswagen Beetle, while the Ford Escort an Volkswagen Golf which wad compete for sales mair effectively against the Kadett C baith got aff tae a relatively slow stairt respectively in 1968 an 1974.
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.
While critics raved about the Calibra's looks and performance, they were less keen on the interior which, despite sporty looking seats and some nice detailing, used a dash lifted straight from the Vectra. The Vectra also donated most of its chassis, which led to some less than flattering road tests at the time. The critics were especially harsh about the gearchange, vague steering and low-speed ride quality, although praise was heaped on the car for overall refinement, keen prices, practicality and performance.
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 Kadett A (above) finally appeared in 1962, and was a classic GM/Opel effort: highly pragmatic, conventional in every respect, reasonably stylish for its time, and designed to deliver a good bang for the buck. In just about every way possible, it was the antithesis of the VW: front-engine rwd, a rather tinny but roomy body, highly tossable but with a primitive suspension and ride, a very roomy trunk, and excellent visibility as well as economy. Oh, and a proper heater even! Its little 987 cc OHV four made 40 net/46 gross hp, six more than the VW 1200. Its trim fighting weight of 1475 lbs (670 kg), some two hundred pounds less than the VW, showed in both its acceleration and body integrity.
