The 2026 IMSA SportsCar Championship (known for sponsorship reasons as the 2026 IMSA WeatherTech SportsCar Championship) is a motor racing championship, which will be the 56th racing season sanctioned by the International Motor Sports Association and traces its lineage back to the 1971 IMSA GT Championship. It will also be the thirteenth season of the IMSA SportsCar Championship since the merger between the American Le Mans Series and the Rolex Sports Car Series in 2014, and the eleventh under the sponsorship of WeatherTech.
The provisional schedule was released on March 13, 2025, and features 11 rounds. The calendar remains the same as the previous season, but the Battle on the Bricks will revert to a 2-hour, 40-minute race as it was in 2023 while the Motul SportsCar Grand Prix event at Road America will be the first in IMSA sports car racing history to run a 6-hour endurance race at that venue.
In accordance with the 2017 LMP2 regulations, all cars in the LMP2 class use the Gibson GK428 V8 engine.

Championship points are awarded in each class at the finish of each event. Points are awarded based on finishing positions in qualifying and the race as shown in the chart below.
Points are awarded in each class at the finish of each event.
Team points are calculated in exactly the same way as driver points, using the point distribution chart. Each car entered is considered its own "team" regardless if it is a single entry or part of a two-car team.
There are also a number of manufacturer championships which utilize the same season-long point distribution chart. The manufacturer championships recognized by IMSA are as follows:
Each manufacturer receives finishing points for its <u>highest finishing car in each class</u>. The positions of subsequent finishing cars from the same manufacturer are not taken into consideration, and all other manufacturers move up in the order.
The points system for the Michelin Endurance Cup is different from the normal points system. Points are awarded on a 5âÂÂ4âÂÂ3âÂÂ2 basis for drivers, teams and manufacturers. The first finishing position at each interval earns five points, four points for second position, three points for third, with two points awarded for fourth and each subsequent finishing position.
At the Rolex 24 at Daytona, points are awarded at 6 hours, 12 hours, 18 hours and at the finish. At the Sebring 12 hours, points are awarded at 4 hours, 8 hours and at the finish. At the Watkins Glen 6 hours and Road America 6 hours, points are awarded at 3 hours and at the finish. At the Petit Le Mans (10 hours), points are awarded at 4 hours, 8 hours and at the finish.
Like the season-long team championship, Michelin Endurance Cup team points are awarded for each car and drivers get points in any car that they drive, in which they are entered for points. The manufacturer points go to the highest placed car from that manufacturer (the others from that manufacturer not being counted), just like the season-long manufacturer championship.
For example: in any particular segment manufacturer A finishes 1st and 2nd and manufacturer B finishes 3rd. Manufacturer A only receives first-place points for that segment. Manufacturer B receives the second-place points.
