But how was Opel/PSA able to shave off so much fat from the hatchback? For starters, all engines will be made from aluminum (-15 kg / 33 lbs), much like the hood (-2.4 kg / 5.3 lbs). The optimized seats (-5.5 kg / 12.1 lbs front and -4.5 kg / 10 lbs rear) contribute to this significant weight loss, while the insulating material used throughout the cabin is also a new weight-saving development. The most important diet is found in the body-in-white, which is a term referring to the body panels being joined together before adding the engine, sub-assemblies, and trim. The new BIW is an impressive 40 kg (88 lbs) lighter than the old one.
All Mexican previous versions were known as the Chevy, with the names Monza used on the saloon, and Swing (five-door) and Joy (three-door) for the hatchbacks, all with a 1.6-liter 78 PS (57 kW) four-cylinder. There was also a low-end three-door model called the Chevy Popular, which was equipped with a 52 PS (38 kW) 1.4-liter engine. The latter 2004 and 2008 redesigns were simply named Chevy and Chevy Sedán. The Chevy was a favourite among taxicab drivers and one of the best selling cars in the country.
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.
Not only was the body a bit bigger, but the Kadett B also had a slightly enlarged 1100 cc engine. This was externally a very compact motor indeed, and looked rather lost in the Kadett’s Kavernous engine bay. Power output increased correspondingly; there were 45 and 55 DIN hp (high compression) versions for Europe; the weaker on was sent stateside with a 54 (gross) hp rating.
Later, an 1800 cc version wis introduced for the Kadett/Astra GTE model. This range o ingines wis an aa uised for later models o the Corsa/Nova, an the mid-sized Cavalier/Ascona. The Kadett D wis an' a' equipped wi a 1600 cc diesel ingine that wis possible tae drive as cheap as 5.0 L/100 km, an a cairy-ower 1196cc OHV ingine. It wis an aa produced as IDA Kadett in Kikinda, Yugoslavie.
