Endurance racing stands out from any other forms of motorsport, in that it tests not only the skill and stamina of the driver, but the reliability of the car, whether its at 24 hours of Le Man’s, 24 hours of Daytona or 12 hours of Sebring.

Car manufacturers boast and take pride in their cars winning but its not just open to the elite manufacturers (Ferrari, Toyota, Porsche, Aston Martin, Peugeot) private and independent teams (privateers) can take part, and there are several classes, for example WEC (World Endurance Championship) has 4 classes Hypercar (New for 2021 was LMP1), LMP2 and LMPGTE with 2 classes PRO & AM.
