The Williams team announced Saturday that Patrick Head, the director of engineering and a founder of the team with Frank Williams in 1977, was leaving its board.
For most of the time, Mr. Williams had served as the business and sporting brains behind the team while Mr. Head was the technical mastermind. During Mr. Head’s tenure, the team won 113 races, nine constructors’ titles and seven drivers’ titles. But the team has not won a race since 2004, and Mr. Head had already taken a step back from the technical director’s role as he groomed Sam Michael for the past several years to take over his role.
This season was the team’s worst — it finished eighth in the series — and Mr. Michael left the team early in the season.
Mr. Head, 65, will no longer work at the team, but he will remain involved in Mr. Williams’s Hybrid Power company as a director.
“Patrick and I have been in partnership for 34 years,” Mr. Williams said. “During that time, he has been the leader of the technical team that has won the majority of our race wins and championships. This is a remarkable legacy, and one which will be treasured and definitely not forgotten.”
