Track Facts

1

Sebring was built on a WWII Army Air Corps training base — parts of the original concrete runways are still used as the track surface today, making it one of the bumpiest circuits in motorsport.

2

The 12 Hours of Sebring is the oldest sports car endurance race in America, first held in 1952.

3

The unique surface makes tire and brake management absolutely critical — teams spend hours studying data to predict degradation.

4

Ferrari, Porsche, Jaguar, and Ford have all built legendary rivalries across Sebring's decades of history.

5

Night racing at Sebring is iconic — the combination of darkness, bumps, and dust makes it one of the most challenging stretches in endurance racing.
