March Engineering was a Formula One constructor and customer car supplier from the United Kingdom. Founded in 1969, the team started racing in 1970. In 1977 the team's assets and FOCA membership were sold to ATS. An ill-fated return in 1981 was made that only lasted two years. The team shifted its intentions across the Atlantic for a while before beginning a new F1 project in 1987 with Leyton House. This team was taken over fully by Leyton House in the middle of 1989, but was sold back for 1992. At the season's end, the funds dried up and despite making an entry to the 1993 South African Grand Prix, the team's F1 career was finished.
