The Istanbul Racing Circuit (Turkish: İstanbul Otodrom) is located on the Asian side of Istanbul, Turkey, close to the junction of Kurtkoy on the north side of TEM Motorway, linking Istanbul to Ankara; it is adjacent to the newly constructed Sabiha Gökçen International Airport. Surrounded by pristine forest and green, cultivated fields, the circuit will be the venue of the Turkish Grand Prix from August 21, 2005.

The circuit, covering over 2.215 million m², runs counter-clockwise at 5,340 m long, with an average width of 15 m ranging between 12.5 and 21.5 m. There are a total of 14 curves (six right turns and eight left), the sharpest having a radius of merely 15 m. With a start/finish straight over 650 m in length, the circuit runs over four level sections, with rising and descending grades. The maximum attainable speed is expected to be 320.5 km/h (199.2 mph) by modern F1 cars. The total race distance will be 309.720 km by 57 laps.

The main grandstand will have a seating capacity of 30,000 spectators. In addition, natural ground stands and temporary stands will provide a total capacity of over 155,000. The paddock buildings are two-level structures; the ground floor reserved for F1 teams, the upper floor serving as hospitality areas, with an additional viewing capacity of 5,000 seats. At each end of the paddock, there are two 7-story VIP towers.

The design of the circuit and the complexes has been made by the famous racetrack architect Hermann Tilke.
