The Mazda RX-792P was a racing car built for the IMSA GT Championship's GTP category for Mazda. Its career was short lived, with only two cars running in 1992 before the project was abandoned.

The car's name would be a combination of Mazda's RX-7 road car, the year the car raced, and the fact that it was a prototype.


Following many successful years running the RX-7 in IMSA's GTO class and MX-6 in the GTU class, Mazda chose to take on a new challenge. Although Mazda has supported the use of their rotary engines in GTP prototypes in the past, Mazda wished to compete with the likes of Porsche, Nissan, Jaguar, and Toyota with a full factory effort. This would coincide with Mazda's continued running of the World Sportscar Championship in Europe, as well as the All Japan Sports Prototype Championship at home.

After Mazda's success in winning the 1991 24 Hours of Le Mans, a change in engine rules by the FIA would force Mazda to abandon their R26B 4-rotor in the World Sportscar Championship. However IMSA rules continued to allow the use of rotaries, which led Mazda to bring the R26B to North America, with refinements to better suit the shorter races and circuits.

For a chassis, Mazda would use the expertise of Crawford Composites to construct their tub, while Fabcar would assist in the project. Due to the different style of racing, the new car would not share much from Mazda's previous effort, the 787B and its predecessors. The tub would be built from carbon fiber, while the bodywork designed by Lee Dykstra would feature new sweeping lines, including a large exposed vent flowing out from the front wheel well.

A total of three RX-792Ps would be built by Crawford for Mazda before the project was cancelled.
