For 1991, Brunner and Chris Murphy designed the CG911 chassis, while the team switched from the Judd V8 engine to the new Ilmor V10. As in 1990, the team struggled early on in the season: Capelli retired from the first nine races despite running in the top six in San Marino and Canada; Gugelmin also struggled to finish during this period but did manage seventh in France. A steady drive in Hungary brought Capelli and the team a point for sixth; the Italian driver then ran in the top six again in Portugal before spinning off. Gugelmin, meanwhile, finished the last five races, recording two more seventh places in Portugal and Spain.
