For 1990, the new-look Subaru Coloni team slimmed down to a single-car effort, driven by Bertrand Gachot. Things started inauspiciously for the team, when Gachot pre-qualified dead-last for the 1990 United States Grand Prix. In fact, Gachot failed to pre-qualify in each and every race that he drove the Subaru-powered C3B, and also the 1990 German Grand Prix and 1990 Hungarian Grand Prix in the new Cosworth-powered C3C. By the 1990 Belgian Grand Prix, however, things had improved marginally; Gachot pre-qualified a Coloni for the first time in a year, but was still 30th and last in qualifying proper. From then onwards, Gachot would regularly pre-qualify his C3C, but never once managed to get through qualifying proper, and Coloni finished the season without ever actually competing in a race.
