Lewis Hamilton's long-time race engineer, Peter 'Bono' Bonnington, will not follow him to Ferrari in 2025, as Bonnington has been promoted to head of race engineering at Mercedes. Despite speculation, a 'non-poaching' clause in Hamilton's contract prevented him from recruiting Bonnington to Ferrari. Bonnington's new role takes effect immediately, though he will continue to work with Hamilton for the remainder of the 2024 season. Andrea Kimi Antonelli is expected to replace Bonnington at Mercedes, while Ferrari's engineering lineup for Hamilton remains undetermined. This marks the end of an iconic partnership that saw Hamilton win six world championships with Bonnington's support.
