The International Motor Sports Association (IMSA) announced the 2019 schedule for the IMSA Prototype Challenge, its longtime prototype-only series that serves as a platform for aspiring future IMSA WeatherTech SportsCar Championship drivers and veteran drivers alike. The series enters its 14th season under IMSA sanction in 2019.
Among the enhancements made to the IMSA Prototype Challenge schedule is the evolution of the endurance racing format that debuted in 2018. One year after shifting from two 45-minute sprint races per weekend to a single one-hour, 45-minute endurance race, the series will extend to a three-hour race format for select events in 2019.
The six-race schedule will feature three-hour endurance races at Daytona International Speedway in early January – run during the Roar Before the Rolex 24 weekend – and Canadian Tire Motorsport Park. The three-hour races will have a minimum of two drivers per car and a maximum of three. All other events will remain one-hour, 45 minutes in length.
“There is no shortage of momentum behind the IMSA Prototype Challenge. We believe three-hour races at Daytona and Canadian Tire Motorsport Park will be another attractive opportunity, not only for our current competitors and stakeholders but also those interested in the rapidly growing LMP3 platform,” IMSA President Scott Atherton said.
All six races on the IMSA Prototype Challenge calendar will be run in conjunction with the WeatherTech Championship.
