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.

As the war progressed, military authorities placed greater stress on the development of air-cooled engines, which they felt had more immunity to damage from weather, shellfire, and misuse. To meet this demand, Opel engineers developed an unusual variation on normal cooling for the 3.6 L truck engine. It was called "air-oil cooling", and used engine oil to take heat away from the jackets around the cylinder barrels. The heads were directly cooled by air, there being three separate aluminium finned heads, each serving two cylinders. Of this interesting engine, which developed 72 hp (54 kW; 73 PS) at 3,000 rpm on 74-octane fuel, only three examples were built.
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.
