Williams has confirmed that its Formula 1 technical chief, Pat Symonds, will leave at the end of the month following three seasons with the team.
Symonds, 63, has enjoyed a career in F1 spanning four decades, including stints with Toleman, Benetton, Renault and Manor.
Symonds left Manor for Williams midway through 2013, and helped to lead the team to successive top-three finishes in the constructors’ championship in 2014 and 2015.
Williams confirmed on Tuesday that Symonds would be leaving the team on December 31 upon the expiration of his three-year contract.
“Pat has been a tremendous asset to this team over the past three years,” deputy team principal Claire Williams said.
“Pat’s appointment was the start of a major restructuring exercise, and he has been pivotal in reshaping Williams into what is a much stronger racing team today.
“I would like to thank him for all of his hard work and commitment during that time. We now look to the future and will be announcing details regarding the team’s technical leadership in due course.”
Williams is rumored to be on the verge of signing Mercedes technical chief Paddy Lowe, with a move possible ahead of the start of the 2017 season in March.
