Istanbul Park (Turkish: İstanbul Park), also known as the Istanbul Racing Circuit or initially Istanbul Otodrom, is a motor sports race track in Akfırat village east of Istanbul, Turkey. It was inaugurated on 21 August 2005. It has been called "the best race track in the world" by Formula One supremo Bernie Ecclestone.
The venue of the Turkish Grand Prix is located in crossing of boundaries of Pendik and Tuzla districts on the Asian side of Istanbul, close to the junction of Kurtköy on the north side of the Otoyol 4, linking Istanbul to Ankara. It is adjacent to the newly constructed Sabiha Gökçen International Airport and is surrounded by forests and fields.
The Istanbul Park racing circuit was one of only five circuits running anticlockwise in the 2011 Formula One season, the others being Autódromo José Carlos Pace (used for the Brazilian Grand Prix), the Marina Bay Street Circuit (used for the Singapore Grand Prix), the Korea International Circuit (used for the Korean Grand Prix) and the Yas Marina Circuit (used for the Abu Dhabi Grand Prix). The circuit is 5.338 km (3.317 mi) long, with an average width of 15 m (49 ft) ranging from 14 to 21.5 m (46 to 70.5 ft), and covers over 2.215 million square metres (547 acres). With a total of 14 corners, the sharpest with a radius of merely 15 m (49 ft), the circuit runs over four different ground levels with a start/finish straight over 650 m (2,133 ft) in length
