Christian Horner, Red Bull's team principal, has officially confirmed that Yuki Tsunoda will drive the RB20 in F1's post-season test.

Although Tsunoda has only experienced Red Bull cars in demonstration events, he previously drove the RB18 at the Goodwood Festival of Speed, wearing an open-face helmet and goggles.

Honda has actively advocated for Tsunoda to test a Red Bull in a more realistic setting, and Koji Watanabe, president of Honda’s racing division, recently shared publicly that Honda had strongly requested Tsunoda be given the chance to test in a Red Bull car.

Horner said that Tsunoda’s test drive had been planned for some time and expressed interest in seeing how Tsunoda performs in a top-tier car.

"Yuki is part of the junior team, and we’ve discussed this with Honda," Horner stated. "He will test the car during the post-season tire test, and this has been arranged for quite a while. It will be valuable for him to have this experience and work with Red Bull Racing engineers in a Red Bull car."

The test comes as Tsunoda’s future with Red Bull looks uncertain. His teammate, Liam Lawson, has already driven the RB20 in a tire test earlier this year and has been linked as a possible replacement for Sergio Perez, whose recent performance has been under scrutiny.

When Horner was asked if a decision would be made about drivers at the season’s end, potentially with Lawson stepping up to Red Bull, he said that Perez remains under contract for next season.

"As I mentioned before, Checo is contracted through 2025," Horner confirmed. "We also have a seat open at VCARB, but all of these drivers are Red Bull Racing team members on loan. We have the time to sit down with Laurent [Mekies, RB team principal] and Peter [Bayer, RB CEO] to consider all options."
