Superspeedway
Track Terminology
A Superspeedway is an oval racing track that is 2 miles (3.2 km) or longer, designed for high-speed motorsport competition.
These massive tracks are primarily found in NASCAR and IndyCar racing, with famous examples including Daytona International Speedway (2.5 miles), Talladega Superspeedway (2.66 miles), and Indianapolis Motor Speedway (2.5 miles). Due to their length and banking, cars can reach extreme speeds exceeding 200 mph.
Superspeedways create unique racing conditions where aerodynamic drafting becomes crucial, often resulting in "pack racing" where large groups of cars run closely together. For safety reasons, NASCAR implements speed-reducing devices like restrictor plates or tapered spacers at these venues.
