IMSA - GTD PRO Class Lightbox

The IMSA WeatherTech SportsCar Championship features two styles of cars – Prototype, which showcases the latest automotive technology and are uniquely designed for the racetrack, and GT, which is based on road-going production models. These two styles of cars make up the series’ four classes – Grand Touring Prototype (GTP), Le Mans Prototype 2 (LMP2), GT Daytona Pro (GTD PRO) and GT Daytona (GTD).

To help fans follow the on-track action, the WeatherTech Championship uses a Leader Light System. It allows fans to easily identify the position of each car in its respective class. The position of the car is displayed on an LED panel mounted on the side of the car and the color of the LED number corresponds with the class. For instance, an illuminated LED red number 5 on a GTD PRO style car means that car is in 5th position in the GTD PRO class.

GT Daytona Pro (GTD PRO)
GTD PRO, which debuted in 2022, include race cars built to FIA GT3 technical regulations and offers the opportunity for factory teams and driver lineups to compete in the class. Manufacturers competing in this class in 2025 include Aston Martin, BMW, Chevrolet, Ferrari, Ford, Lamborghini, Lexus, Mercedes-AMG and Porsche.
