Like many long-time Saab enthusiasts I'm not happy with the way GM is handling its Swedish partner. Saab was a truly individualistic automaker that based its designs on aircraft practise, featured two-stroke engines, showed the world how a hatchback should be designed, and later developed an advanced turbocharger to offer startling performance. For several years it also built a limited-production sports car, the Sonnett. And so, on Sunday, October 15, Saab fans will be gathering on the Swedish Car Day at the Larz Anderson Museum in Brookline, Massachusetts to celebrate the Sonnett's 50th anniversary. Among the participating cars will be several key members of the Saab Automobile USA heritage collection, including Sonetts of each generation. The first Sonnett was actually a race car created for a series in 1956 that never materialised. The second version appeared in 1967, first with a 3-cylinder two-stroke engine, then with a more powerful V-4 four-stroke. The final version (the coupe in our photo), with updates by Italian designer Sergio Coggiola, appeared in 1970. Total production since inception was 10,236 cars.
