Endurance racing is widely regarded as the toughest, most tiring and most grueling type of motorsport of them all. Drivers and teams must cooperate for up to 24-hours to ensure victory and success. Teams must make sure their cars are capable of lasting throughout the rough time period while ensuring they perform as well. The same applies to the strength of the drivers. The 24H series consists of a range of racing classes: it features GT3 cars, GT4 cars, sports cars, touring cars and 24H specials. The series is approved by the F.I.A and endurance races take place on worldwide racing circuits including the Nurburgring, Le Mans, Silverstone and many more.
