The struggling Williams team has appointed co-founder Patrick Head as a consultant to assist its engineering department.
Head, 72, founded the team with Frank Williams in 1977 and played a key role in spearheading its car design department. In that role he helped guide the team's success in the 1980s and 1990s, when it claimed all of its seven drivers' and nine constructors' championship trophies -- only Ferrari has won more of the latter.
Head stepped away from an active role with the team in 2011. His return was confirmed by the team in a story on the official F1 website on Friday.
