Sebring International Raceway

Located in central Florida, Sebring International Raceway is one of the most iconic and historic circuits in North American motorsports. Originally a World War II bomber airfield known as Hendricks Army Airfield, it was converted into a race track in 1950. Since then, Sebring has become world-renowned for hosting the 12 Hours of Sebring, a grueling endurance race that attracts top international teams and drivers every year. Its unique layout, which still uses portions of the original airfield's concrete runways, has made it a proving ground for cars, teams, and endurance racers alike.

The Driving Line

Sebring is famous for being rough, technical, and brutally honest. It’s a track that puts both driver skill and car reliability to the test. The mix of old concrete and modern asphalt creates constantly changing grip levels, and the bumpy surface forces drivers to stay focused every lap. A smooth, adaptable driving style and strong endurance mindset are essential here.

• Track Length: 3.741 miles (6.021 km)
• Number of Turns: 17
• Elevation Change: Minimal (approximately 10 feet / 3 meters), but surface undulation is constant

Key Challenges & Driving Notes

• Turn 1: A flat-out left-hander over rough concrete—easy to upset the car if the line or balance is off.
• Turns 3–5: A technical, flowing section that requires precision to carry speed into the short straights.
• Hairpin (Turn 7): One of the best overtaking zones, but heavy braking over uneven surfaces makes it tricky.
• Le Mans Curve (Turn 16): A fast right-hand sweep that sets up the back straight—vital for lap time.
• Turn 17 (Sunset Bend): The final corner is wide, fast, and extremely bumpy—perfect for last-lap drama and testing car control.
