TheSirius Autodrom (Russian:Сириус Автодром,romanized: Sirius Avtodrom), known before 2024 asSochi Autodrom (Russian:Сочи Автодром,romanized: Sochi Avtodrom)[2] and originally as theSochi International Street Circuit[3] and theSochi Olympic Park Circuit, is a 5.848 km (3.634 mi) permanent race track in the settlement ofSirius next to theBlack Sea resort city ofSochi inKrasnodar Krai, Russia.[4][5]
Earlier theInternational Olympic Committee was given the power to delay the race until2015 if preparations for the race interfered with the Winter Olympics,[6] though the Games started without interruption. In October 2011, the Russian government set aside US$195.4 million for the construction of the circuit.[7]
The construction of the Sochi Olympic Park Circuit marked the end of a thirty-year campaign for a Russian Grand Prix, with plans for a "Grand Prix of the Soviet Union" originating as early as1983 before being abandoned for "bureaucratic reasons"[8] and several failed attempts[9][10][11] in the intervening years. The circuit received its final approval from the FIA in August 2014.[12]

The 5.848 km (3.634 mi) circuit was the fifth-longest circuit on the 2021 Formula One calendar, behindSpa-Francorchamps in Belgium,Jeddah Corniche Circuit in Saudi Arabia,Baku City Circuit in Azerbaijan andSilverstone in the UK.[13] The circuit is built around the Sochi Olympic Park, that is the coastal cluster of Olympic venues built for the2014 Winter Olympics that have hosted competitions in ice hockey, speed skating, curling, figure skating, short track etc., andFisht Olympic Stadium where Opening and Closing ceremonies were held.

The circuit, designed by German architectHermann Tilke, has the start grid on the northern edge of the Olympic Park next to therailway station, heading southwest towards theBlack Sea coast. Then it runs along the outer edge of the centralSochi Medals Plaza, that is the podium for Olympic medal ceremonies. The long Turn 3 has been compared to Turn 8 inIstanbul Park.[15] Then, the track circles the plaza counterclockwise and makes three turns around theBolshoy Ice Dome. Then follow series of tight corners before turning north where the track skirts the edge of the Olympic Park, above the main Olympic Village and theAdler Arena Skating Center. Then it passes theskating andcurling centres, before funneling up behind the pit paddock toward the train station, and completing a circuit with two ninety-degree right turns.[citation needed] The circuit held the Russian Grand Prix from 2014 to 2021.[16]
The circuit was initially planned to be included in the 2022 Formula One calendar, but the Russian Grand Prix was suspended on 24 February 2022, then it was cancelled on 1 March 2022, due to theRussian invasion of Ukraine.[17][18][19]
With international championships leaving Russia it was decided to dismantle the big circuit, leaving only the short layout where turn 1 is connected to turn 13. The last race at the old layout, which was the Russian Endurance Cup, took place 4 November 2023; the grand prix circuit was closed 6 November and the shorter layout was started to be primarily used from 15 December.[20]
On 1 April 2024, the Sochi Autodrom was renamed to Sirius Autodrom, after theSirius urban-type settlement which was built near the Olympic Park back in 2020.[21]
The official lap record for the current circuit layout is 1:35.761, set by Lewis Hamilton during the 2019 Russian Grand Prix. As of November 2025, the fastest official race lap records at the Sirius Autodrom are listed as:
