Opel also produced the first mass-production vehicle in Germany with a self-supporting ("unibody") all-steel body, closely following the 1934 Citroën Traction Avant. This was one of the most important innovations in automotive history. They called the car, launched in 1935, the Olympia. With its small weight and aerodynamics came an improvement in both performance and fuel consumption. Opel received a patent on this technology.
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.
At the first round of the season held at the former Grand Prix track of Zolder in Belgium, Opel Team Joest’s misfortunes continued. Manuel Reuter retired in the early stages, with both John Winter (16th) and Keke Rosberg finishing a lap down on winner Alessandro Nannini (ITA) in the Alfa. Race 2 was more positive however, with only John Winter dropping early on. Reuter lead the Opel charge in 7th, with Rosberg in 10th.
the Chevy Chevette, while a MUCH better car than the Vega was at the time, and even now, that’s not saying a whole lot, other than it WAS infinitely more durable and longer lasting and reliable than the Vega, though by ’76, the Vega was decent enough, but the damage was done. I know as my Mom drove a ’76 Vega from roughly 78-83 with the only major thing being the carb being rebuilt around 1980. The Chevette was basically a redesigned Kadett/Vauxhaul Chevette.
