The Korea International Circuit is a 3.49-mile (5.61-km) racing facility designed by the famous German track architect Hermann Tilke and paved in Yeongam, South Korea, along the shore of the Yellow Sea. The FIA Grade 1 Korea International Circuit hosted the Formula 1 Korean Grand Prix four times, from 2010 to 2013, and regularly hosts GT1 World Championship and GT Asia Series competitions. The design of the circuit allows spectators from the beach and adjacent hotels to see the races, and the pit lanes go through a part of the street public roads. There are four distinct seasons in Yeongam, with lots of rainfall, especially in summer.
The Korea International Circuit has two possible configurations for racing, both of them running in the counterclockwise direction. The Grand Prix Course includes the whole 3.49-mile (5.61-km) trajectory of the race track. Local motorsport events use the shorter National Circuit, which only covers the northern part of the track. Some of the most remarkable features of the raceway include its 1.16-km (0.72-mile) long back straightaway, its sharp multi-apex turn number three, and the highly technical sneaking stretch from turn six into turn eighteen. The average speed is 81 mph (130 km/h), with a top speed of 149 mph (240 km/h).
The National Raceway of the Korean International Circuit is a 10-turn, 1.89-mile (3.04-km) configuration traveling through the northern part of the track. Most of the grandstands for the 135,000 spectators gathered for high-profile motorsports events are around this layout. The average speed on this variation is 81 mph (130 km/h), with an average lap time of 1:24.3.
