2024 IMSA SportsCar Championship

The 2024 IMSA SportsCar Championship was a motor racing championship, which was the 54th racing season sanctioned by the International [Motor Sports Association] and traces its lineage back to the 1971 [IMSA GT Championship]. It was also the eleventh 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 ninth under the sponsorship of WeatherTech. Following a change in class structure for the 2024 season, the IMSA SportsCar Championship saw a major expansion of its full-time grid across all of its classes.

Classes

At the end of the 2023 season, IMSA discontinued the involvement of the Le Mans Prototype 3 class from the main championship. The class was originally introduced in 2021 as a means of bolstering the overall grid size, which had seen a record-low 38 starting cars in the 2020 24 Hours of Daytona. IMSA cited the growth of the GTP class as a contributing factor to dropping LMP3 for 2024 onwards, in addition to growth in other classes.
GTP is the flagship class of the championship, and consists of two sister technical regulations: Le Mans Daytona h, and Le Mans Hypercar. The former regulation allows developing a bespoke design from a base chassis with a specification hybrid system on all cars, with freedom on aerodynamics and engine configuration. The latter regulation allows bespoke hybrid designs, and offers more design freedom in exchange for elevated development costs.
The GTP class is made of the same framework that comprises the Hypercar class of the FIA World Endurance Championship, in accordance with the collaborative alliance between IMSA and the French racing organizers ACO, which resulted in the convergence of the two organizer's top class regulations.
Unlike the other classes, LMP2 remained without BoP, even though there were two separate chassis in the class for the first time since 2021.

The provisional schedule was released on August 4, 2023, and featured 11 rounds.

Calendar changes

Lime Rock Park was dropped from the calendar. The track had been a part of the championship since 2015.
The Michelin Endurance Cup expanded to 5 rounds, with the event at Indianapolis Motor Speedway transforming from a sprint race in 2023 to a six-hour endurance race for 2024.
After a 1-year hiatus, Detroit returned to the IMSA calendar, with a sprint race on the Streets of Detroit.
On September 7, 2023, the Watkins Glen date was moved one week earlier than originally announced, to avoid a clash with the 24 Hours of Spa.
Canadian Tire Motorsport Park lost their GTP entries from previous seasons, with the LMP2 category becoming the headline category.

Points systems

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.

Position	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26	27	28	29	30+

; Drivers points
Points are awarded in each class at the finish of each event.
; Team points
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.
; Manufacturer points
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 highest finishing car in each class. The positions of subsequent finishing cars from the same manufacturer are not taken into consideration, and all other manufacturers move up in the order.
; Michelin Endurance Cup
The points system for the Michelin Endurance Cup is different from the normal points system. Points are awarded on a 5–4–3–2 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.

Position	1	2	3	Other Classified
Race	5	4	3	2

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 Indianapolis 6 hours, points are awarded at 3 hours and at the finish. At the Petit Le Mans, 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, 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.
