Zhou Guanyu, China's first Formula One driver, released a statement on his personal social media account on Wednesday officially announcing his impending departure from Sauber at the end of the 2024 season.

In the statement, Zhou emphasized his unwavering focus and desire to continue driving in Formula One.

"This has been a difficult season, but I am still putting all my effort into the remaining races. I care about my future and want to stay here as long as possible, so I am fighting for it. The opportunity is still there," the 25-year-old wrote.

"I am delighted with the achievements I have made amid the fierce competition of F1, including scoring points on my debut, setting the fastest lap in treacherous conditions at the Suzuka Circuit and executing some exciting offensive and defensive maneuvers on the track.

"I am full of confidence in the future, and focused on truly showcasing my abilities."

Looking back at Zhou's highlights in F1, he made his debut in Bahrain in 2022 as a rookie driver for Alfa Romeo, finishing 10th and becoming the 66th driver in the history of F1 to score points on his debut.

Zhou has since brought a legion of new fans to Formula 1 — and, together with Valtteri Bottas, played a key role in Sauber-run Alfa Romeo securing a top six finish in the constructors' championship in 2022.

The last two seasons, however, have been difficult, and he's struggled to consistently match his teammate — though it should be noted mechanical issues on his side of the garage have hampered his progress.

Sauber also confirmed the departures of Bottas and Zhou on Wednesday, at the same time announcing next season's arrival of Brazilian rookie Gabriel Bortoleto to the team.

Twenty-year-old Bortoleto will team up with the more experienced 37-year-old Nico Hulkenberg in 2025.

The McLaren junior Bortoleto currently tops the F2 standings.

"This is one of the exciting projects in motor sport, if not in all sports," Sauber, which will become the Audi entry in 2026, quoted him as saying.

"Joining a team that combines the rich motor sport history of Sauber and Audi is a true honor."

Bottas and Zhou are set to depart at the end of the season after both failing to register a point in this season's driver's championship so far.

"After open and constructive discussions with Valtteri Bottas and Zhou Guanyu, we mutually concluded that conditions to continue together could not be met, so we agreed that it is time to part ways," Sauber said.

"We would like to thank both for the contribution they have made to the team in the last three years.

"They have been the embodiment of professionalism, using their experience and enthusiasm to support our growth."

Last month, Bottas said he would consider returning to Mercedes next year as a reserve driver if he was not retained by Sauber.

Zhou will be leaving the team that made him China's first F1 driver, but remains positive that his journey at the top of the sport will continue.

"Sadly, the last two seasons have been challenging for all, but I want to look forward," Zhou said in his statement, adding: "I am now discussing a number of options to stay in the Formula One paddock."
