March Engineering was a Formula One constructor and manufacturer of customer racing cars from the United Kingdom. Although only moderately successful in Grand Prix competition, March racing cars enjoyed much better success in other categories of competition, including Formula Two, Formula Three, IndyCar and IMSA GTP sportscar racing. 1970s March Engineering began operations in 1969. Its four founders were Max Mosley, Alan Rees, Graham Coaker and Robin Herd. The company name is an acronym of their initials. They each had a specific area of expertise: Mosley looked after the commercial side, Rees managed the racing team, Coaker oversaw production at the factory in Bicester, Oxfordshire, and Herd was the designer. The history of March is dominated by the conflict between the need for constant development and testing to remain at the peak of competitiveness in F1 and the need to build simple, reliable cars for customers in order to make a profit. Herd's original F1 plan was to build a single-car team around Jochen Rindt, but Rindt became dismayed at the size of the March programme and elected to continue at Team Lotus. March's launch was unprecedented in its breadth and impact. After building a single Formula Three car in 1969, March announced that they would be introducing customer cars for F1, F2, F3, Formula Ford and Can-Am in 1970, as well as running works F1, F2 and F3 teams. The Formula One effort initially looked promising, with March supplying its 701 chassis to Tyrrell for Jackie Stewart. These cars were merely a stopgap for Tyrrell, who no longer had the use of Matra chassis and were in the process of constructing their own car; March was the only option available given clashing fuel contracts. In addition, the factory ran two team cars for Jo Siffert (Porsche were paying for his drive) and Chris Amon sponsored by STP. A third STP car, entered by Andy Granatelli for Mario Andretti, appeared on several occasions. Ronnie Peterson appeared in a semi-works car for Colin Crabbe when his works Formula Two commitments allowed; various other 701s went to privateers. The team constructed ten Formula One chassis that year, in addition to Formula Two, Formula Three, Formula Ford and Can-Am chassis. Stewart gave the March its first Formula One victory, at the 1970 Spanish Grand Prix, and both Amon and Stewart took a non-championship race victory, but the works team did not win a
