The second race of the IMSA WeatherTech SportsCar Championship season (second round of the North American Endurance Cup) extended a 66-year tradition as Sebring International Raceway played host for the annual 12 Hours of Sebring. Perfect conditions saw the race run at a frantic pace in the opening stages before being slowed by a series of caution periods in the second half of the event. As darkness fell, the final two hours of the race featured a sprint to the finish with Ferrari once again well figuring in the final results.
