The last race of the year generally presents a number of “lasts.” This year’s Motul Petit Le Mans is no different.

FOX Sports, Patron and Continental are among those signing off from IMSA after this year’s season finale. NBC Sports takes over as the television broadcast partner in 2019.

As part of Michelin’s increased effort to become the Official Tire of IMSA in 2019, Michelin takes over sponsorship of the renamed Michelin Endurance Cup and MICHELIN Pilot Challenge.

Within the WeatherTech Championship, Michelin will add the Prototype and GT Daytona classes to its lineup. It also takes over as tire partner for the IMSA Prototype Challenge series.

Both existing IMSA Challenge series – Continental and Prototype – also wrap up their 2018 campaigns this weekend in Atlanta. Those races are both on Friday (Prototype at 8 a.m., Continental at 1:25 p.m.).
