Daniel Ricciardo has confirmed his return to Red Bull as their reserve driver for 2023.
The Australian left McLaren at the end of the F1 season in Abu Dhabi with his contract terminated a year early following a two-year stint.
Ricciardo raced for Red Bull from 2014 to 2018 and won seven Grand Prix races with the team before a brief spell with Renault ahead of his two years with McLaren.
He is hoping to be back in F1 as a full-time driver in 2024 but will be in reserve for world champion Max Verstappen and Sergio Perez next year.
“The smile says it all, I’m truly excited to be coming back home to Oracle Red Bull Racing as their Third Driver in 2023,” Ricciardo said.
“I already have so many fond memories of my time here, but the welcome from Christian, Dr Marko and the entire team is something I’m sincerely appreciative of.
“For me personally, the ability to contribute to and be surrounded by the best team in F1 is hugely appealing, whilst also giving me some time to recharge and refocus. I can’t wait to be with the team and support with simulator work, testing sessions and commercial activities. Let’s go!”
Ricciardo finished 11th in the driver's standings in 2022, largely down to much-improved performances in the second half of the season. He was publicly criticised by McLaren chief Zak Brown after the Spanish Grand Prix for his 'below-par' displays.
Red Bull boss Christian Horner added: "It is great to bring Daniel back into the Red Bull family. He has enormous talent and such a brilliant character; I know the whole factory is excited to be welcoming him home.
“In his role as test and third driver, Daniel will give us the chance to diversify, assisting in the development of the car, aiding the team with his experience and knowledge of what it takes to succeed in F1."
