The FA1B, second Osella F1 car, was the further development of 1980’ FA1. Although the design and construction were very much the same as the original FA1, the new “interim” FA1B was both narrower and lighter. In 1981 Osella expanded to a two-car team with the wealthy Italian F2 driver Beppe Gabbiani in the lead car. The second was driven by Argentinian Miguel Ángel Guerra in first four rounds of the season, then Piercarlo Ghinzani and Giorgio Francia took the car for a couple of races, and finally arrival of experienced Jean-Pierre Jarier put some stability to the team. Denim remained as main sponsor but Monopolio Tabacchi, the Italian state-owned tobacco company, withdrew their MS funding. Jarier, who joined the team at German GP, was regular starter and more or less regular finisher, while Gabbiani mostly has been stopped by qualifying barrier. The Italian failed to qualify in 12 out of 15 races of the season, and retired in all 3 rounds when he did participate. In 1982 he went back to Formula 2 when he achieved 3 wins and 3rd place in the European Championship in 1983. In the 1990s Gabbiani raced a lot in Italian national sports car events and as well as in the International Sports Racing Series.
