# Sochi Autodrom

The Sirius Autodrom (Russian: Сириус Автодром, romanized: Sirius Avtodrom), known before 2024 as Sochi Autodrom (Russian: Сочи Автодром, romanized: Sochi Avtodrom) and originally as the Sochi International Street Circuit and the Sochi Olympic Park Circuit, is a 5.848 km (3.634 mi) permanent race track in the settlement of Sirius next to the Black Sea resort city of Sochi in Krasnodar Krai, Russia.
The circuit runs around a former Olympic complex, the Sochi Olympic Park site, scene of the 2014 Winter Olympic Games. The TCR International Series raced at Sochi in 2015 and 2016.
The inaugural World Championship Russian Grand Prix took place in 2014, with the circuit hosting the Grand Prix up to 2021. The contract was terminated before the 2022 edition due to the Russian invasion of Ukraine.

## Development

Earlier the International Olympic Committee was given the power to delay the race until 2015 if preparations for the race interfered with the Winter Olympics, though the Games started without interruption. In October 2011, the Russian government set aside US$195.4 million for the construction of the circuit.
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 as 1983 before being abandoned for "bureaucratic reasons" and several failed attempts in the intervening years. The circuit received its final approval from the FIA in August 2014.

## The circuit

The 5.848 km (3.634 mi) circuit was the fifth-longest circuit on the 2021 Formula One calendar, behind Spa-Francorchamps in Belgium, Jeddah Street Circuit in Saudi Arabia, Baku City Circuit in Azerbaijan and Silverstone in the UK. The circuit is built around the Sochi Olympic Park, that is the coastal cluster of Olympic venues built for the 2014 Winter Olympics that have hosted competitions in ice hockey, speed skating, curling, figure skating, short track etc., and Fisht Olympic Stadium where Opening and Closing ceremonies were held. The surface was not laid until after the Closing Ceremony of the Olympics.
The circuit, designed by German architect Hermann Tilke, has the start grid on the northern edge of the Olympic Park next to the railway station, heading southwest towards the Black Sea coast. Then it runs along the outer edge of the central Sochi Medals Plaza, that is the podium for Olympic medal ceremonies. The long Turn 3 has been compared to Turn 8 in Istanbul Park. Then, the track circles the plaza counterclockwise and makes three turns around the Bolshoy 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 the Adler Arena Skating Center. Then it passes the skating and curling centres, before funneling up behind the pit paddock toward the train station, and completing a circuit with two ninety-degree right turns. The circuit held the Russian Grand Prix from 2014 to 2021.
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 the Russian invasion of Ukraine.
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 circuit was closed 6 November and the shorter layout was started to be primarily used from 15 December.
On 1 April 2024 the Sochi Autodrom was renamed to Sirius Autodrom, after the Sirius urban-type settlement which was built near the Olympic Park back in 2020.
