Why it matters
The Sonett Super Sport, unofficially the Saab 94, was Saab's first sports car, built outside normal company channels by engineers in their spare time. Racing rule changes ended plans for series production.
How rare is it?
Six separate kinds of rarity – never combined into one number.
Each kind of rarity is rated separately and never combined.
02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionSonetts built | 61,2 | Factory production | Factory reported |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
Engine designer Rolf Mellde began sketching a two-seater in 1954. With little support from management he and colleagues built the car from early 1955 in a rented barn at Asaka, with Sixten Sason making the model from which the fibreglass body was moulded. The car was ready on 14 October 1955 and was shown at the Stockholm Motor Show in 1956 with 57.5 hp and a stated top speed of 210 km/h. It went to the US for the introduction of Saab there in April 1956.
In November 1956 five further cars were ordered, built by the ASJ railway works with bodies from Katrineholm; Silodrome says two were for exhibition and three for competition. Series production, considered at Jensen in Britain and then at ASJ for 2,000 cars a year, was dropped because competition rules from 1958 allowed modified production cars.
