In 2012, Opel announced the closure of the Bochum plant (now known as Plant Bochum II), effective 2016, with the loss of approximately 3,000 jobs, in response to the manufacturer's longstanding over capacity and loss of market share in key western European markets. Ellesmere Port in England became Opel's lead plant for the Astra/Kadett platform for subsequent generations.
I join in the question: “Where did they all go?” These were pretty common in the upper midwest (as imports went) in the late 60s-mid 70s. I knew a Lutheran minister who owned one (maybe a 69 or so?) in the mid 70s, and got to ride in it once. He seemed pretty proud of the fact that he had put about 80K on it and it seemed to be running strongly. Although it was starting to look a little worn, it seemed to hold up a lot better than my Scoutmaster’s 69 Cortina.
My brother’s best friend’s family traded in the “kids’ car”, a much abused ’55 Chevy six two door on a new ’67 Kadett B, like this one, and every bit a stripper like the Chevy 150 had been. Geoffrey was a capable driver, and some of my more memorable mind-expanding experiences in the year 1967 – 1969 came about thanks to their willingness to let younger brother tag along. That often involved sitting in the back seat of the Kadett, hanging on for dear life as every effort to catch air on the winding back roads was exploited. Perpetual caning was SOP, and I have doubts whether their Kadett lasted as long as the old ’55 Chevy six. My father’s Kadett A needed a valve job at 40k, probably precipitated by my brother’s similar abuse. He traded it in on a ’68 Dart; that tells you all you need to know.
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.
