The Argo JM19, and its derivatives/evolutions, the Argo JM19C, and the Argo JM19D, are a series of IMSA GTP Lights/Group C2 sports prototype, designed, developed, and built by British constructor Argo Racing Cars, for the IMSA GT Championship, introduced in 1985.[2] Its use in sports car racing continued into the early 1990s. It won a total of 7 races, and scored a total of 21 podium finishes. It was powered by a number of different engines, including a Mazda 13B rotary engine, a Buick V6 turbo engine,[3] a Ferrari V8 engine, and even a Ford-Cosworth DFL V8 Formula One-derived engine.[4] It did, however, find most of its success when equipped with the Mazda-powered Wankel rotary engines.[5][6][7][8][9]
