The Saab 92 was the first production car from Saab. The design was very aerodynamic for its time, with a drag coefficient (cx or cw) of 0.30. The entire body was stamped out of one piece of sheet metal and then cut to accommodate doors and windows. Full-scale production started December 12, 1949, based on the prototype Ursaab. All of them were of the Deluxe version. A standard version was advertised, but nobody was interested in buying it so no standard versions were produced. The engine was a transversely-mounted, water-cooled two-cylinder, two-stroke 764 cc displacement, 25 hp (19 kW) engine based on a DKW design, giving a top speed of . The transmission had three gears, the first unsynchronised. In order to overcome the problems of oil starvation during overrun (engine braking) for the two-stroke engine, a freewheel device was fitted. The suspension was by torsion bars. All early Saab 92s were painted in a dark green colour similar to British racing green. According to some sources, Saab had a surplus of green paint from wartime production of airplanes; "All the cars were painted bottle green, a colour that became something of a trade mark for Saab cars. The underlying reason was that the armed forces had bought large quantities of a green cellulose paint for camouflage painting. However, the paint did not suit the terrain and the entire consignment of paint was sold off. Saab bought it and that was why both the aircraft and cars ended up green." Saab's rally history already started two weeks after the 92 was released, when Saab's head engineer Rolf Mellde entered the Swedish Rally and came second in his class. Only 700 1950 models were made. In 1951, the German VDO instruments were replaced by American Stewart-Warner components. In 1952 Greta Molander won the 'Coupe des Dames' of the 0 in a 92, tuned to 35 hp (26 kW). In 1953, the 92B arrived with a much larger rear window and larger luggage space (with an opening lid). It was now available in grey, blue-grey, black and green. In 1954 the Saab 92 got the new Solex 32BI carburetor and a new ignition coil giving 28 hp (21 kW). The US headlights were replaced with Hella units. Another novelty was that a textile roof (semi-cab or cabrio coach) was offered as an option. The colour maroon was also introduced this year. In
