ELKHART LAKE, Wis. – The 2018 IMSA WeatherTech SportsCar Championship schedule has been revealed on Friday, with only a couple changes from this year.
As announced last week, the series’ return to the Mid-Ohio Sports Car Course takes place May 4-6, replacing Circuit of The Americas on the calendar.
The other change sees the GT Daytona class drop a round of the season, going from 12 races to 11, and drops the Long Beach race from the calendar. That reverts the race back to just the Prototype and GT Le Mans classes.
With just three classes in 2018, the Prototype Challenge class set to come to an end in two races, most WeatherTech Championship events will have all classes in action. The GT-only races at Lime Rock Park and VIRginia International Raceway continue and the Detroit street race will be just Prototype and GT Daytona.
“The 2018 WeatherTech Championship schedule again showcases the stability of our platform, while at the same time reaffirming our commitment to the best road racing venues and events in North America. And this time offering a few surprises for our fans,” said IMSA President Scott Atherton. “Each race on our 2018 calendar has a rich history of sports car competition, which we expect to be at an all-time high next season across all three classes.”
All four Tequila Patron North American Endurance Cup races continue as well.
The WeatherTech Championship schedule is below:
The 2018 season will kick off with the annual three-day Roar Before the Rolex 24 At Daytona test session on Jan. 5-7. The test is mandatory for all Rolex 24 participants.
