A new, multi-class, sprint-race series will make its debut in 2023 as IMSA officials today unveiled the IMSA VP Racing SportsCar Challenge, with entitlement sponsorship from longtime partner VP Racing Fuels.

As revealed by Sportcar365 last month, the series, which will replace IMSA Prototype Challenge, will be open to LMP3 and GT4 cars, in 45-minute sprint races with one driver per car.

The new series class names will be LMP3 and GSX respectively.

To be eligible to drive in either class, all drivers must have an FIA driver categorization of either Bronze or Silver. A five-event, ten-race schedule is planned for the series.

IMSA Michelin Pilot Challenge will continue in its traditional endurance format, featuring the GS and TCR classes competing across a ten-race schedule.

“We are grateful to our longstanding partners at VP Racing Fuels for expanding their relationship with us to bring a new and different brand of excitement for IMSA race fans,” said IMSA President John Doonan.

“LMP3 and GT4 cars, drivers and teams have delivered fantastic competition over the years. Putting them together in a sprint format is a fresh and differentiated approach that we expect will be popular with fans and competitors alike.”

Each VP Racing SportsCar Challenge event weekend will include a qualifying session in which the fastest timed lap will set the field for the first race.

The second fastest qualifying lap by each car will determine the starting grid for the second race of the weekend.

There will be no pit stops during the races, and all race cars will ride on Michelin tires.

The series further expands a robust partnership between IMSA and VP Racing Fuels.

Since 2014, VP has supplied the Official Fuel of IMSA, and in 2020, the company added the distinction of Official Performance Coolant of IMSA with its “Stay Frosty” line of automotive coolants.

Last year, the partnership expanded again, becoming the Official Performance Additive of IMSA with VP’s “Madditives” line of fuel treatments and octane boosters.

“VP Racing and IMSA have enjoyed a nearly decade-long partnership, bringing world-class racing to racers and fans around the globe,” said Bruce Hendel, Senior Vice President of Global Sales for VP Racing.

“We are proud to enhance our relationship as the entitlement sponsor of the IMSA VP Racing SportsCar Challenge, an appropriate entitlement, signifying our continued commitment to IMSA.”

All series races will be streamed live in the U.S. on Peacock, with television coverage airing post-event on USA Network. Live race streaming for international audiences will be available on
