Sergio Sette Camera was seen as a substitute driver for both Red Bull Racing and Alpha Tauri earlier this year. However, the situation is complicated by Brazil’s commitment to attend the Super Formula in Japan and the restriction of travel may prevent him from participating in the race at the weekend. Since then, the reserve role has been for Sebastien Buemi, who recently raced in F1 with Toro Rosso in 2011. In case Red Bull / AlphaTauri needs a racer, they can pick up Pierre Gasly or Daniil Kvyat and The position of these riders will be reserved.
Alfa Romeo’s driver Antonio Giovinazzi has become the official reserve driver for Ferrari, and the Italians will be ready if needed. The team also had Pascal Wehrlein on the reserve list though the last time the German racer ran in F1 was with Sauber in 2017.
Woking-based racing team had Serge Sirotkin on standby last year. However, after signing an engine supply contract with Mercedes in 2021, they agreed to use Brackley riders. So Vandoorne and Gutierrez are both available. Racing Point also has a similar agreement. And also do not forget that Alonso still kept in touch with McLaren despite playing in the Indy 500 and therefore, the presence of the Spaniard can not be ruled out.
The reserve list is dominated by young and test runners, notably with Guanyu Zhou and Christian Lundgaard. Therefore, Hulkenberg is clearly a better option for Renault, while Sirotkin has also had ties with Renault in the past.
Silverstone-based racing teams do not have their own riders and for several years, they had an agreement with Mercedes. In addition, the team is still in good relationship with Hulkenberg to see him as a reserve rider if needed.
Robert Kubica is the official reserve for the Hinwil-based racing team, and the Polish driver will also be summoned if Giovinazzi takes over the position at Ferrari. Last year, IndyCar racer Marcus Ericsson was considered a substitute last year and tested the team in Austria.
Louis Deletraz and Pietro Fittipaldi are reserve riders to be considered.
In recent times, Grove-based racing teams have approached Mercedes drivers like Esteban Ocon and George Russell. However, earlier this year, they officially announced F2 star Jack Aitken on the reserve list.
