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.
At the end of the 2023 season, IMSA discontinued the involvement of the Le Mans Prototype 3 (LMP3) 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.
[1] GTP is the flagship class of the championship, and consists of two sister technical regulations: Le Mans Daytona h (LMDh), and Le Mans Hypercar (LMH).
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.
Points are awarded based on finishing positions in qualifying and the race as shown in the chart below.
There are also a number of manufacturer championships which utilize the same season-long point distribution chart.
