March 74S

The March 74S was a sports prototype racing car built by March Engineering in 1974. It was designed to compete in the FIA World Championship for Makes and other sports car racing series. The "S" designation stood for "Sports."

The 74S was a successor to the earlier March sports prototypes, such as the 73S. It featured an open-cockpit design and was typically powered by a Cosworth DFV 3.0-liter V8 engine, although some examples were fitted with other engines. The chassis was a lightweight aluminum monocoque, and the car incorporated advanced aerodynamics for the period.

Several privateer teams and occasionally the factory-supported March team campaigned the 74S in various racing events throughout the 1974 season and beyond. While not always a dominant force, the March 74S proved to be a competitive and reliable car, achieving some notable results in the hands of experienced drivers. Its performance contributed to March's reputation as a versatile constructor capable of producing competitive cars across various racing disciplines, including Formula One, Formula Two, and sports car racing.

The car played a significant role in the history of sports car racing during the 1970s, highlighting the engineering innovation and design trends of the era. The March 74S, along with other similar sports prototypes, helped to define the competitive landscape of the FIA World Championship for Makes.
