The Calibra holds the title of having been the most aerodynamic car in the world at its 1990 launch, with a drag coefficient of just 0.26. With engines ranging in displacement from 1998 cc to 2498 cc, the car reigned supreme over other makes at the time. Its privileged position as the most aerodynamically efficient car would be held until the end of the 90's when the Calibra was overthrown by new Audi and Honda releases, the A2 and Insight respectively.
My parents bought a brand new ’67 Opel Kadett Rallye, was red/white from our local Buick dealer. I believe the price was under $2K back then. Pretty unusual around the neighborhood, as most back then drove Caddy’s, big Chryslers and V-8 Station Wagons. It had a manual stick and a am radio and bucket seats. Got pretty good mileage and our dog liked to ride around in the back window. Learned to drive in it and after awhile was quite comfortable to drive around..wished now I had it..pretty rare now..even back then.
Rüsselsheim. The sixth-generation Opel Corsa is based on a completely new design, which is the basis for an increase in efficiency. The Corsa will celebrate its premiere before the end of this year. Whether diesel, petrol or – for the first time – electrically powered, every new Corsa benefits from the lower weight: the driving dynamics improve, the fuel consumption falls. The lightest version of the next generation even undercuts the magical 1,000-kilogramme mark – excluding driver, the five-door will weigh only 980kg. Compared with its predecessor, this model variant is a useful 108kg lighter. This is a weight-saving of around 10 per cent, although the new model has a similar length of 4.06 metres. Reducing so much weight while retaining similar dimensions is a remarkable development achievement that directly benefits the customer.
Opel also produced the first mass-production vehicle in Germany with a self-supporting ("unibody") all-steel body, closely following the 1934 Citroën Traction Avant. This was one of the most important innovations in automotive history. They called the car, launched in 1935, the Olympia. With its small weight and aerodynamics came an improvement in both performance and fuel consumption. Opel received a patent on this technology.
Chevrolet has only released a teaser photo of the redesigned 2016 Spark minicar so far, but the final product has been hiding in plain sight as the Opel Karl that debuted at the Geneva auto show. The Chevrolet version will have a slightly different look with its brand-specific fascias, but the European-market Karl otherwise provides a good preview of the U.S.-market Spark we’ll see at the New York auto show in a few weeks.
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.
