The year of 1967 would be an auspicious one for for the Trollhättan-based carmaker. The start of the year witnessed the maiden flight of the aircraft division’s advanced new Viggen jet fighter aircraft, while that Autumn, the first completely new Saab motor car since the marque’s inception would make its press debut. The 99 model (and its derivatives) would go on to Continue reading “Nordstjärna (Part Four)”
The early 1960s had been good years at Trollhättan. Saab sales had risen exponentially, the export performance of the 96 showed considerable promise, and its rally exploits further bolstered its appeal. But it was clear that to consolidate upon this success, a more modern, more adaptable Saab motorcar was required. In April 1964 management initiated Project Gudmund which would culminate in the 99 model, unveiled to the press in November 1967.
But meanwhile sales of the two-stroke 96 were stalling, and technical chief, Rolf Mellde recognised the need to act. Not that his engineers had exactly been warming their hands in the interim. Between 1960 and 1964, a number of four-stroke engines were evaluated in Saab bodyshells. Initially three powertrains were selected, a longitudinal 897 cc four cylinder Lloyd Arabella unit, a transversely mounted 848 cc BMC A-Series (à la Mini) and a 1089 cc V4 Lancia Appia unit.
