Furthermore, the front end was completely stripped of any superfluous sheet metal, and was clad in a composite one-piece clamshell to reduce weight and increase rigidity. The changes were complemented by lighter multi-spoke BBS wheels, and an evolved aerodynamics package, which further distanced the car from the production model. Meanwhile, Cosworth managed to extract some more revs (up to 12,800) to fire 457 horsepower at all four wheels.
¹Opțional. Funcționează automat între 5 km/h și 85 km/h. Între 5 și 30 km/h, decelerarea pentru reducerea vitezei de impact este de 0,9 g. Într 30 și 85 km/h, sistemul reduce viteza cu maxim 22 km/h. După acest prag, șoferul trebuie să frâneze singur pentru a reduce și mai mult viteza. Gama de viteze de funcționare a AEBPD depinde de obstacolul detectat (mobil: între 5 și 85 km/h; fix: între 5 și 80 km/h; pietoni: între 5 și 60 km/h). Sistemele Opel de asistență pentru șofer au rolul de a asista șoferul în cadrul limitărilor imanente ale sistemului. Șoferul rămâne responsabil pentru sarcinile conducerii. Se preconizează că va fi disponibil din toamna anului 2017.
Sistem automatskog kočenja u hitnim situacijama1 prepoznaje pešake i druga vozila koja ste možda prevideli. Pri brzinama između 5 i 85 km/h, sistem konstantno meri razdaljinu do drugih vozila i upozorava vas ako vam prilaze prevelikom brzinom / ako je razdaljina prekratka. Ako ne reagujete, sistem automatski započinje kočenje u slučaju opasnosti i smanjuje brzinu vozila. Pri brzinama ispod 30 km/h, automobil će kočiti do potpunog zaustavljanja.
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.
In 1982 Opel once again accomplished a great feat with a small car: the Corsa A joined the range below the Kadett, which by now was becoming a compact model. Designed by Chief Designer Erhard Schnell, who also penned the legendary Opel GT, the only 3.62m-long Corsa was notable for its prominent rally-car wheel arches and a drag coefficient of 0.36. Offered initially as a two-door hatchback and sedan, and a five-door as of 1985, the Corsa again demonstrated how masterfully Opel can generate space on a small platform. The 100hp GSi also combined frugality with fun. Originally conceived as an entry-level model for those on a tight budget, the Corsa A had become a bestseller by 1993 with a total of 3.1 million units sold.
The Corsa is a supermini introduced by General Motors’ European subsidiary Opel in 1983 and produced until today. It has also been sold under a variety of other brands (most notably Vauxhall, Chevrolet and Holden) and names and spawned various derivatives in different markets, all of which are listed in appropriate sections below.Despite its global presence, it has never been sold in the United States or Canada.
The new four-cylinder, oversquare one-litre water-cooled Opel OHV engine weighed only 96 kg and was the first all-new engine developed by Opel since before the war. The side-mounted camshaft was driven not through gear-cogs but using a single chain with a hydraulic tensioner, the valve train employing rocker-arms and light-weight hollow rods. The arrangement was low on weight and on friction, permitting engine speeds above 6,000 rpm. The pistons were formed from an aluminium-alloy and incorporated a bimetal expansion strip to ensure uniform thermal expansion. The three-bearing forged crankshaft was of more traditional construction. The carefully designed aluminium inlet manifold provided for efficient feed of the fuel-mixture to the cylinders and helped provide the engine with good fuel economy characteristics.
The Kadett A (above) finally appeared in 1962, and was a classic GM/Opel effort: highly pragmatic, conventional in every respect, reasonably stylish for its time, and designed to deliver a good bang for the buck. In just about every way possible, it was the antithesis of the VW: front-engine rwd, a rather tinny but roomy body, highly tossable but with a primitive suspension and ride, a very roomy trunk, and excellent visibility as well as economy. Oh, and a proper heater even! Its little 987 cc OHV four made 40 net/46 gross hp, six more than the VW 1200. Its trim fighting weight of 1475 lbs (670 kg), some two hundred pounds less than the VW, showed in both its acceleration and body integrity.
