The March CG891 was introduced at the Monaco Grand Prix, the March 881 having served duty for the March Racing Team in the first two races of the year. Gugelmin qualified in 14th while Capelli was 22nd on the grid. He had to revert to the 881 for part of qualifying as his CG891 developed electrical problems. Both drivers failed to finish although Capelli was still classified in 11th. This was the Italian's first of only two classified finishes all year, the other coming in Belgium, where he placed 12th. Gugelmin's best finish was seventh, achieved three times; in Belgium, Japan and Australia.
