March 75A
Racing car model
From Wikipedia, the free encyclopedia
The March 75A was an open-wheel formula racing car, designed, developed and built by British manufacturer and constructor, March Engineering, for Formula 5000 racing, in 1975. It was based on the March 761 Formula One car. Unlike most other F5000 cars of the time, which used 5.0 L (310 cu in) V8 engines, the 75A used a smaller 3.4 L (210 cu in) Ford-Cosworth GAA V6 engine (which was still allowed; and permitted with F5000 regulations), which produced between 420–470 hp (310–350 kW) @ 9,000 rpm, depending on tuning and spec. Engines up to 5,000 cc (310 cu in) could be used, so this was still perfectly in line with the regulations.[1][2][3][4]
