The new IMSA VP Racing SportsCar Challenge will debut with a six-event calendar for the new sprint series comprising currently homologated LMP3 and GT4 race cars.
Each event will include two classes – LMP3 and GSX (GT4) – with 45-minute sprint races and no pit stops.
To be eligible, drivers must be either Bronze- or Silver-rated and all cars will ride on Michelin tires.
The first confirmed event for 2023 will be at Sebring International Raceway on the weekend of March 11-12 as part of the FIA World Endurance Championship Prologue test.
Four additional events will run as a companion to the WeatherTech Championship at WeatherTech Raceway Laguna Seca, Canadian Tire Motorsport Park, Virginia International Raceway and Michelin Raceway Road Atlanta.
A sixth event remains to be confirmed.
Of note, IMSA did not confirm the series that will join the NASCAR Cup Series on the streets of Chicago on July 1.
