Sebring International Raceway is a road course auto racing facility located in Sebring, Florida.
Sebring (pronounced "sea bring") Raceway is one of the oldest continuously-operating race tracks in the United States, its first race being run in 1950. Many consider Sebring to be one of the classic race tracks in North American sports car racing, and the 12 Hours of Sebring, 24 Hours of Daytona, and 24 Hours of Le Mans to be the trifecta of endurance racing.
The raceway occupies a portion of Sebring Regional Airport, an active airport for private and commercial traffic that was originally built as a WWII Army Air Forces training base called Hendricks Field.
Sebring started life as a United States Army Air Forces training base. From 1941 to 1946, pilots learned to fly the B-17 Flying Fortress. This lineage was commemorated by a special livery on Gunnar Racing's Panoz in the 2002 12 Hours of Sebring resembling a World War II-era B-17.<ref>Gunnar Racing</ref>
After the war, aeronautical engineer Alec Ullmann, seeking sites to restore military aircraft for civilian use, saw potential in Hendricks' runways to stage a sports car endurance race, similar to the 24 Hours of Le Mans. Sebring's first race was held on New Year's Eve of 1950. The Sam Collier 6 Hour Memorial race was won by Fritz Koster and Ralph Deshon in a Crosley Hot Shot that had been driven to the track by Victor Sharpe. This first race attracted thirty racecars from across North America.<ref>http://www.ggw.org/~cac/Sebring/Sebring.html</ref>
The first 12 Hours of Sebring was held on March 15, 1952, and would grow to be a major international race. In 1959, the racetrack hosted the first Formula One Grand Prix in the United States. Due to the poor attendance and high costs, the next United States Grand Prix was held at Riverside.<ref>The United States Grand Prix</ref>
For much of Sebring's history, the track followed a 5.2 miles (8.4 km) layout. In 1967, the Webster Turn right between the hairpin and the top of the track was removed and replaced with the faster Green Park Chicane, which was closer to the hairpin and allowed a flat-out run through a very fast corner to the top of the track and the runway, which made the circuit 50 yards longer. In 1983, the track was changed to allow simultaneous use of the track and one of the runways. In 1987, more changes allowed use of another runway. Further changes in 1991 accommodated expansion of the airport's facilities, and brought the track close to its current configuration. The entire track could now be used without interfering with normal airport operations. In 1997, the hairpin was removed due to a lack of run-off, and replaced with what became known as the "safety pin". Gendebien Bend was also re-profiled to slow the cars' entry to the Ullman straight.<ref>12 Hours of Sebring</ref>
The track now is leased by the Panoz Motor Sports Group, who acquired the facility from Andy Evans in 1997.<ref>The TACH Report: USRRC Announces '98 Sched, Panoz Buys Sebring From Andy Evans, GM Has New Longer Range Battery For EVs</ref>
The track will often be recognized for its famous, high-speed "Turn 17", a long, bumpy, fast right hander that can make or break a car's speed down the front straight. The corner can fit up to 3 cars wide.
Skip Barber Racing School holds numerous programs at the facility, including a Scholarship opportunity for young racers.
The course of the track is 3.7 miles (6.0 km) long. It is a seventeen-turn road course with long straights, several high-speed corners, and very technical slower corners. Many of the turns and points along the track are named for the early teams and drivers. There is very little elevation change around the track and little camber on the surface, providing a challenging track for drivers, especially when it rains.
Sebring is renowned for its rough surface. The course still runs on old sections of World War II-era landing fields that were constructed of concrete sections with large seams. The transitions between sections are quite rough and often, sparks fly from the undercarriages of the cars as they traverse them. Much of the track has intentionally been left with its original concrete runway surface. The track surface has 3.0 miles (4.8 km) of asphalt and 0.7 miles (1.1 km) of concrete. Mario Andretti, a 3-time 12 Hours winner, said that one of the hardest parts about the original Sebring track was finding the track to begin with! There had been many accounts of drivers retiring due to accidents at night, quite simply because they got lost on the runway sections and couldn't find the track again. <ref>About Sebring Raceway</ref>
Sebring is most notable for hosting the 12 Hours of Sebring, sanctioned at various times by the FIA, IMSA, and now, the ALMS. The track also hosts the Historic Sportscar Racing series, and is the winter home of the Skip Barber Racing School. Many IndyCar, sports prototype, and Grand Touring teams use Sebring for winter testing due to the warm climate.
