Former Formula One champions Williams have been sold to U.S.-based private investment firm Dorilton Capital, they announced on Friday with a statement that marked the end of an era for the family-owned team.
They will continue to race under the Williams brand and remain at their Grove headquarters in England, the statement added.
It said the deal for Williams Racing was supported unanimously by the board, including 78-year-old founder Frank Williams, and would secure the long-term success of the struggling team.
"This may be the end of an era for Williams as a family owned team, but we know it is in good hands," deputy principal Claire Williams said.
