An evolved endurance format and the addition of Mid-Ohio are the main features of IMSA’s 2019 schedule for its Prototype Challenge class, which will feature an all-LMP3 lineup next year.
A 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. All other events will remain one-hour, 45 minutes in length. 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.
“We received positive feedback from our IMSA Prototype Challenge competitors on the debut of the endurance format this season,” said IMSA President Scott Atherton. “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.”
