[2] After two more races with double retirements,[2] the CG911's best result of the season came at the 1991 Hungarian Grand Prix; not only did both cars finish, but Capelli was able to take sixth place, one lap behind the leader.

[12][13] However, Akagi was arrested in connection with the Fuji Bank scandal,[14] and, needing the funds to keep going, Leyton House replaced Capelli with Karl Wendlinger for the 1991 Japanese Grand Prix, who brought backing from Mercedes-Benz.

[12][15] Although Wendlinger had an unsuccessful debut for the team, as he was taken out by Andrea de Cesaris's Jordan (as were both the Dallaras of JJ Lehto and Emanuele Pirro), Gugelmin continued his run of finishes with an eighth place.

[17] For the 1992 season, Leyton House were rebranded as March F1, after they were sold to a consortium led by Ken Marrable, John Byfield, Tony Birchfield, Gustav Brunner and Henny Vollenberg.

[18] However, the 1992 season did not start well for March, as Wendlinger retired from the 1992 South African Grand Prix with an overheating engine after 13 laps, and Belmondo failed to qualify.

[20] The 1992 Monaco Grand Prix was one to forget for the team; not only did Belmondo fail to qualify, but Wendlinger retired due to gearbox failure on the first lap.

[27] This was Wendlinger's last race for the team; he was replaced by veteran racer Jan Lammers for the 1992 Japanese Grand Prix, where Naspetti finished 13th.

[32] They entered the 1993 South African Grand Prix with Lammers and Jean-Marc Gounon, but did not compete; although their cars arrived at the Kyalami circuit, the engines did not.
