In 1909, the Opel 4/8 hp pioneered the introduction of affordable mobility. It was modern with solid technology, easy to operate and manoeuvrable, enabling ambitious car owners to drive it themselves instead of relying on a chauffeur – considerably reducing the overall cost of ownership. And the quality of materials and workmanship created confidence. The first officially designated “small car” in automotive history was considered fully suitable for everyday use. The vehicle ideal for “doctors, veterinarians and lawyers” according to the adverts was available at prices from 4,000 to 5,000 Marks, while models from other manufacturers cost around 20,000 Marks. Thus the means of transport for the upper class became a vehicle for the middle class - thanks to the “Doctor's car”.
Typically, although a far better car, like the Chevette all Kadett models have been the butt of jokes in Europe, particularly for being very common (the quintessential middle-class car in Germany and the Netherlands), very prone to rust and very easy to steal. While essentially good cars, and always praised as such by contemporary press, these gave Opel its commoner reputation it is still struggling to shake off.
Technologically, the Kadett D was a departure, as it was Opel and Vauxhall's first front-wheel-drive car. It was also the first application of the Family II engine design, with a single overhead camshaft, aluminium-alloy cylinder head, hydraulic valve lifters, with capacities of 1297 cc (producing 60 PS and 75 PS) and had a transaxle design that allowed the clutch to be replaced without removing the transmission unit. A carry-over 1196 cc Opel OHV engine from previous generations of the Kadett producing 53 hp and a top speed of 87 mph was also offered on entry level models from launch, and a new 1600 cc engine was offered after Frankfurt 1981, followed by an 1800 cc version introduced for the Kadett GSE/Astra GTE model. The Kadett D was also equipped with a 1600 cc diesel engine, an option which was first presented at the Brussels Motor Show in 1982. Another frugal model, mostly sold in Italy, was the 1.0 liter model with 50 PS (37 kW).
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.
1 = Optional on SC / SE - late 2017. Automatic Emergency Braking with Pedestrian Detection works automatically at speeds between 5 and 140km/h. For speeds between 5 and 30km/h a 0.9g deceleration is applied to reduce the impact speed of the collision. For speeds of 30 to 140km/h the system reduces the speed by up to 50km/h. To reduce speed by over 50km/h the driver needs to provide additional braking. The operational speed range depends on the type of obstacle detected:
While the Ipanema clearly succeeded the Marajó, production of the Chevette (by now in sedan form only, the hatchback having been discontinued after the 1987 model year) and of the Kadett noticeably overlapped; the newer model was placed above the old one in Chevrolet's lineup. While Chevrolet entertained the possibility of a pick-up version of the Kadett E, it never materialized.
