March's attention in the early 1980s was mainly split between F2 and breaking into the IndyCar market. It is a curious irony that although March's FW07 copy bombed in Formula One, when developed into the 81C Indycar it was instantly successful (largely down to George Bignotti's direct involvement in developing the car). Cosworth-powered Marches won the Indianapolis 500 five straight times between 1983 and 1987. The March 86C actually won the race twice in a row, 1986-1987. On the other hand, when Williams directly licensed the FW07 design to Bobby Hillin, the resultant Longhorn cars were a failure.
