Concept ADAC GT Masters:
Fascination on four wheels
The ADAC GT Masters is a grand tourer-based auto racing series founded by the international Stéphane Ratel Organisation (SRO) and supported by the German ADAC automotive club. Similar to an earlier ADAC GT Cup series in the 1990s, the new GT Masters ran their first season in 2007. Although the series is based in Germany, select events are run elsewhere in Europe.
Concept IMSA WeatherTech SportsCar Championship
The WeatherTech SportsCar Championship is a sports car racing series based in the United States and Canada and organized by the International Motor Sports Association (IMSA). It 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. At its inception, the name was United SportsCar Championship, which subsequently changed to the Tudor United SportsCar Championship when Rolex SA signed their Tudor brand to a title sponsorship deal.
