Leyton House Racing competed as a constructor in the 1990 and 1991 seasons. In fact it was a rebranding of the March team which had returned to F1 in 1987, backed by Japanese Leyton House real rstate Company. For the 1990 season, the team used the CG901 chassis, designed by Adrian Newey and powered by a Judd V8 engine. For 1991, Brunner and Chris Murphy designed the CG911 chassis, while the team switched from the Judd V8 engine to the new Ilmor V10. Lined up to drive the CG911 were Ivan Capelli and Mauricio Gugelmin, who drove for Leyton House / March since 1987 and 1988, respectively. The season was definitely a step down for the team. The car lacked pace and both Gugelmin and Capelli struggled. The only point was scored for Capelli’s sixth place at Hungary. Gugelmin’s best result amounted to three seventh-place finishes, although he retired from eight of the season’s sixteen races. In September, the team’s principal, Akira Akagi, was implicated in a financial scandal involving the Fuji Bank and was arrested. Akagi’s associate Ken Marrable took over the running of the team, but money was now short. After the season the team was sold to a consortium including Marrable, Brunner, lawyer John Byfield and Dutch motorsport businessman Henny Vollenberg. For the 1992 season it reverted to the March name. For 1992, Capelli would sign for Ferrari while Gugelmin left for Jordan.
