Nyck de Vries, Jack Doohan and Antonio Giovinazzi are all being given tests by Alpine as the French side aim to find a team-mate for Esteban Ocon next year.
Alpine started the season with Ocon and Fernando Alonso as their main drivers, and Oscar Piastri as a reserve, but the Spaniard was out of contract at the end of the season.
Team principal, Otmar Szafnauer, could not decide whether he wanted Alonso or Piastri to be their driver of choice going forward, and both became tired of the situation.
Alonso opted to join Aston Martin in place of the retiring Aston Martin, while the Australian made a deal with Zak Brown to join McLaren, replacing the struggling Daniel Ricciardo.
Thus far, Alpine have not been able to secure a replacement, but they have a list of 14 drivers who could take Alonso’s place.
Ocon has made it clear that he wants Haas’ Mick Schumacher alongside him in 2023, and the German has not yet secured a deal with Guenther Steiner to stay on board beyond the end of this year.
De Vries made an extremely impressive stand-in appearance in place of Alex Albon with Williams in Monza, so he too is being considered, although he has also been holding talks with Red Bull about a seat with AlphaTauri.
Were the Red Bull junior team to acquire him, it would likely be in place of Pierre Gasly, who is under contract until the end of 2023.
If Alpine do go for the 26-year-old, de Vries would likely be Dr Helmut Marko’s driver of choice to slot in alongside Yuki Tsunoda.
Jack Doohan has impressed in Formula 2 this year, and he is part of the Alpine driver academy, while Antonio Giovinazzi had previously been linked with a move to Haas in place of Schumacher.
That signature may yet transpire for the Italian, but he is being given a run-out by Alpine to assess his suitability.
Giovinazzi previously raced for Alfa Romeo between 2019 and 2021, and he took a year out to compete in Formula E with Penske.
Alpine will run their programme in Budapest and, if they have not yet signed anyone by the end of the year, they will have a test in Abu Dhabi after the season finale to further scout out talent.
