Main Article: Mazda RT24-P
A variation of the prototype, the Mazda RT24-P, was created for the IMSA's WeatherTech SportsCar Championship Prototype class under the DPi regulations. The car was developed in partnership with Mazda Motorsports, and initially SpeedSource Race Engineering, as well as Multimatic. In place of a Gibson V8, a Mazda MZ-2.0T 2.0 L Turbo I4 sits in its place. Other alterations from the Mk30 include a revised sidepod, as well as nose. The cars made their debut at the 2017 Rolex 24 Hours with the SpeedSource Team, before the cars were withdrawn from competition for redevelopment following the Mobil1 Sportscar Grand Prix, held at the Canadian Tire Motorsports Park. Two prototypes are currently running in the WeatherTech SportsCar Championship, with Mazda Team Joest.
