For the 1991 Formula One season, Osella Squadra Corse was gone; the team re-appeared as Fondmetal Corse. Initially, Fondmetal entered the FA1M-E car which was a mere carry-over from the previous year (and, in fact, from 1989 as Osella had not been able to construct a new car in 1990). Driven by Olivier Grouillard, the blue and grey coloured machine was uncompetitive by any means. Although Fondmetal was able to use Cosworth engines prepared by Brian Hart for the previous years' Tyrrell, even Pedro Chaves in his Coloni was ahead of the Fondmetal car. In that hostile atmosphere, pre-qualification turned out to be impossible. But Rumi had high hopes for the European season. By the San Marino Grand Prix, a new car appeared, called the Fomet-1. It was conceived by a newly founded think-tank in the UK called Fomet. The Bicester-based design office was headed by Tino Belli and founded by Rumi who thought that British input was necessary for gaining success. The Fomet-1 featured new aerodynamics, a new suspension and some other improvements, but apart from this, the new car obviously preserved its Osella roots. Finally, things improved a little, but not significantly. With the new car, Grouillard managed to be faster than the Coloni machine, but that does not mean that Fondmetal was able to pass pre-qualifying regularly. Only a handful of race participations were possible, but results were poor, although Grouillard did qualify 10th for the 1991 Mexican Grand Prix, ahead of Andrea de Cesaris in the Jordan, who eventually finished 4th. In the end, Grouillard was replaced by former AGS man Gabriele Tarquini who finished twice (from three attempts), although he also failed to pre-qualify once; but no points were scored in the end.
