Istanbul Park (Turkish:İstanbul Park), also known as theTOSFED İstanbul Park, is amotor sportsrace track in theTuzla district ofIstanbul,Turkey. Designed byHermann Tilke, it opened on 19–21 August 2005. It has been called "the best race track in the world" by formerFormula One Chief ExecutiveBernie Ecclestone, who held the managing rights of the circuit between 2007 and 2011.[5][6][7] The circuit was then managed by the Turkish company Intercity since October 2012 to March 2024.[8] After Intercity, the operator was firstly changed as Can Bilim Eğitim Kurumları A.Ş. in April 2024 for 30 years, however its tender rights was cancelled in December 2024 by the administrative court.[9][10] In June 2025, it was announced that the operating rights of this circuit was given toTurkish Automobile Sports Federation [tr] for at least 10 years, and the name was changed as TOSFED İstanbul Park.[11]
The venue of theTurkish Grand Prix is located in the crossing of boundaries of Pendik and Tuzla districts on theAsian side of Istanbul, close to the junction of Kurtköy on the north side of theO–4 motorway, linking Istanbul toAnkara; and close to the junction of Istanbul Park on the south side of theO–7 motorway. It is nearSabiha Gökçen International Airport and is surrounded by forests and fields.
The circuit is 5.338 km (3.317 mi) long, with an average width of 15 m (16 yd) ranging from 14 to 21.5 m (15.3 to 23.5 yd), 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 (16 yd), the circuit runs over four different ground levels with a start/finish straight over 650 m (710 yd) in length.
The track can hold about 125,000 spectators. The main grandstand has aseating capacity of 25,000 spectators, with natural ground stands and temporary stands allowing for around 100,000 more. The paddock buildings are two-level structures; the ground floor reserved for racing teams, the upper floor serving as hospitality areas with 5,000 seats. At each end of the paddock, there are two 7-storyVIP towers.
Turn 8 (nicknamed "Diabolica" by some in reference toMonza'sCurva Parabolica) particularly caught the imagination. The corner is a fast, sweeping corner with four apexes, similar to one of the multi-apex sections of the oldNürburgring. Spectators and drivers alike raved about Turn 8, comparing it to legendary corners such asEau Rouge and130R. The corner eventually became the basis of some of Tilke's newer track turns, such as turns 17 and 18 at theCircuit of the Americas, turn 3 at theSochi Autodrom, andBuddh International Circuit's turns 10 to 11. The high loads exerted through this corner contribute to the circuit's reputation for rapid tyre wear.[13]
Another notable corner is Turn 1, a sharp downhill left-hander immediately after the front straight. This corner has been nicknamed by some as the "Turkish Corkscrew" in reference to the famousCorkscrew atWeatherTech Raceway Laguna Seca. Both the 2006 F1 and MotoGP races at the circuit featured multiple incidents at this corner. A third noteworthy area is the uphill kink in the middle of the back straight; due to its similarity to Eau Rouge, it has been jokingly referred to as "Faux Rouge".
The circuit is not, however, without its critics. After qualifying,Jenson Button claimed that the track was getting bumpier as the weekend went on, particularly at Turn 8, which was what caused so many drivers to spin off. This harks back to another circuit designed by Hermann Tilke,Shanghai International Circuit, which is said to be sinking in places because it was built on the site of a formerswamp.Jarno Trulli was notable for his lukewarm feeling towards the circuit, saying that he felt the circuit was easy to learn, and that good performance was down more to the car than the driver.[14]
The first Grand Prix of Turkey took place in 2005.[15] Due to financial disagreement, the last Turkish Grand Prix took place in 2011, despite earlier reports that the event would take place until at least 2021.[5] The top speed measured of anF1 car by the speed trap was 329.5 km/h (204.7 mph) in 2005. F1 cars equipped with the smaller 2.4-litre V8 engines (instead of the 3.0-litre V10s of previous years) reached 320 km/h (200 mph) in 2006.Felipe Massa has an affinity with this circuit, with the Brazilian winning three of the nine Grands Prix held at Istanbul Park withLewis Hamilton winning two andSebastian Vettel,Jenson Button,Kimi Räikkönen andValtteri Bottas having won one race each.
Istanbul Park was due to replace the cancelledCanadian Grand Prix for the2021 Formula One World Championship.[17] Then it was postponed indefinitely due to COVID-19 travel restrictions imposed on the country by the UK government and was replaced by theStyrian Grand Prix.[18] It was later re-added to the 2021 calendar in place of the cancelled Singapore Grand Prix.
In 2006, the winner of theGP2 race wasNelson Piquet Jr., however the real battle was withLewis Hamilton who, at the beginning of the race, spun off and dropped right down the field from 2nd to 16th.[19] However he raced his way back through the pack with some spectacular overtaking moves to finish in second.
MotoGP raced at Istanbul Park for three years between 2005 and 2007.Marco Melandri won the races in 2005 and 2006 with the 2007 race being won byCasey Stoner. After the venue was taken over by now ex-Formula One chief executiveBernie Ecclestone in 2007, the venue was dropped from the 2008 calendar.
The official lap record for the current circuit layout is 1:24.770, set by Juan Pablo Montoya during the2005 Turkish Grand Prix. While the unofficial all-time track record is 1:22.868, set by Lewis Hamilton in the qualifying of the2021 Turkish Grand Prix.[21] As of August 2025, the fastest official race lap records at the Istanbul Park are listed as:
