Mercedes has announced that Technical Director James Allison has extended his contract with the team in a new multi-year deal.
Allison originally joined Mercedes in 2017 and won several World Championships with the Brackley-based squad.
In 2021, Allison transitioned to the Chief Technical Officer role within the organisation and was responsible for INEOS Britannia America's Cup project before returning to the Technical Director role last year.
Mercedes has endured a challenging two seasons in F1 as it slipped back in the pecking order following the introduction of new regulations in 2022.
Allison's extension follows the news that Mercedes' Team Principal Toto Wolff has also committed to the team after the Austrian penned a new three-year deal earlier this week.
Mercedes outlined that Allison's extension “reinforces the technical leadership of the team during a period of renewal ahead of the major rule changes for 2026.”

Speaking about the extension, Allison stated: “F1 has brought me a lot of good fortune, but none greater than answering Toto's call to join Mercedes in 2017.
“It is a great privilege to continue this adventure, working alongside brilliant colleagues and fighting together for championship success."
Wolff and Allison have joined its drivers Lewis Hamilton and George Russell in committing their futures to the team, with the drivers locked down until at least the end of 2025 after signing new deals last year.
"I am thrilled that James has committed his long-term future to the team,” added Wolff.
“Put simply, he is the most impressive technical leader in our sport. His gladiator spirit, along with his knowledge, experience, and determination, make him second-to-none. His influence and impact, however, goes so much further than that.
“Since joining in 2017, he has been a key ally and sparring partner for me personally. We can challenge each other openly and honestly; an embodiment of the 'tough love' culture of the team that is vital in helping us all perform at our very best.
“Most importantly though, James is a true friend you can rely on, not only in times of success but in difficult moments too. It has been a pleasure to work with him over the past seven years and I look forward to doing so for many more to come."
