IMSA WeatherTech SportsCar Championship
GT Daytona (GTD) Class involves production models that are enhanced, but not defined technology. Featuring by pro-am drivers, these cars don’t feature the same level of aerodynamics and power as the GTLM class.
The IMSA WeatherTech SportsCar Championship is a result of a merger between two existing North American sports car racing series, the American Le Mans Series and Rolex Sports Car Series. The initial United SportsCar Championship name of the series was announced on March 14, 2013, while Rolex SA signed their Tudor brand to a title sponsorship deal. WeatherTech later signed a deal to take over title sponsorship of the series starting in 2016, rebranding the series. The inaugural 2014 season began with the Rolex 24 Hours of Daytona on January 25–26 and ended with the Petit Le Mans on October 4.
The IMSA WeatherTech SportsCar Championship features sports cars modified and built by worldwide manufacturers as real racing cars. The WeatherTech Championship has three different classes, two being based on road-going super cars (GTLM, GTD) and one being entirely a prototype car (P), demonstrating the latest automotive technology.
Utilizing the same technical regulations as the 24 Hours of Le Mans, the GTLM/GTD cars are the most elite and fastest GT cars on the track. Based on production models, they are engineered to extract the maximum performance possible. The class serves as a true proving ground for leading manufacturers such as BMW, Corvette, Ferrari, Ford and Porsche.
