IMSA Prototype Challenge (formerly IMSA Prototype Lites) was a racing series featuring two classes of single-seat prototype cars racing simultaneously. The series was sanctioned by the International Motor Sports Association (IMSA). Most races were held in support of the WeatherTech SportsCar Championship.[1] The series raced LMP3 class prototype sportscars. The cars have grown in size and speed since its 2006 introduction, starting from four-cylinder and motorcycle powered race cars to large V8 powered cars. Each race was 1 hour and 45 minutes long apart from the season opening 3 hour race at Daytona International Speedway.

The series' final season was in 2022. For 2023, the series was replaced with the IMSA VP Racing SportsCar Challenge.[2]
