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.
The parent company PSA is also preparing the transition to the electric age: By 2025, the carmaker intends to offer offshoots with electric or hybrid drive for all 40 models of its brands. It will start in 2019 with all-electric versions of the Peugeot 208 (reservations opened in the UK last month) and the DS3 Crossback. An electric version of the Peugeot 2008 will follow in 2020. PSA’s plug-in hybrid offensive starts in 2019 with a corresponding offshoot of the DS7 Crossback, the PHEV versions of the Peugeot models 3008 and 5008, the Citroën C5 Aircross and the Grandland X mentioned above.
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.
