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.
As the war progressed, military authorities placed greater stress on the development of air-cooled engines, which they felt had more immunity to damage from weather, shellfire, and misuse. To meet this demand, Opel engineers developed an unusual variation on normal cooling for the 3.6 L truck engine. It was called "air-oil cooling", and used engine oil to take heat away from the jackets around the cylinder barrels. The heads were directly cooled by air, there being three separate aluminium finned heads, each serving two cylinders. Of this interesting engine, which developed 72 hp (54 kW; 73 PS) at 3,000 rpm on 74-octane fuel, only three examples were built.
Opel operates 10 vehicle, powertrain, and component plants and four development and test centres in six countries, and employs around 30,000 people in Europe. The brand sells vehicles in more than 60 markets worldwide. Other plants are in Eisenach and Kaiserslautern, Germany; Szentgotthárd, Hungary; Zaragoza, Spain; Gliwice, and Tychy, Poland; Aspern, Austria; Ellesmere Port, and Luton, Great Britain.[37] The Dudenhofen Test Center is located near the company's headquarters and is responsible for all technical testing and vehicle validations.
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.
