Class Markings & Specifications

Class Markings & Specifications

   
The TUDOR United SportsCar Championship features two (2) styles of cars, Prototype and GT (Grand Touring). Each style of car has two (2) classes, Pro and Pro-Am, meaning there are four (4) classes of racing on track together, each with their own battle for the lead.
 
Pro (Red) & Pro-Am (Blue)  

The Pro classes typically feature a professional driver line up while the Pro-Am classes pair a professional driver and amateur driver.

To help fans easily identify a class of car, the TUDOR United SportsCar Championship implemented a new color system for 2014. A Pro class is designated by RED markings on the number panel, mirror, windscreen banner, rear wing end plate, class decal, and leader light.

A Pro-Am class is designated by BLUE markings on the number panel, mirror, windscreen banner, rear wing end plate, class decal, and leader light.

Leader Light System  

To help fans follow the on track action, the TUDOR United SportsCar Championship has introduced a revolutionary and state-of-the-art Leader Light System for the 2014 season. 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 near the rear.

The color of the LED number corresponds with the red (Pro) and blue (Pro-Am) colors utilized in both the Prototype and GT style of cars. For instance, a red No. 5 LED number on a GT style car means that car is in 5th position in the GTLM class.
