The new General Motors-backed Cadillac Formula 1 team, set to debut in 2026, will enter the sport powered by Ferrari engines.
Initially, the Andretti-Cadillac F1 bid had secured a handshake agreement for Renault-Alpine to supply its engines. However, with Renault's exit from F1 engine production at the end of 2025, Cadillac was forced to consider alternatives. Talks reportedly narrowed the choice to Ferrari and Honda.
"Choosing the right power unit partner is crucial, and we trust in Ferrari's passion, excellence, and the exceptional capabilities of their people," said Graeme Lowdon, the team's new boss and former Marussia chief.
Ferrari confirmed the partnership, revealing that the agreement includes both power units and gearboxes supplied by Maranello.
"It means we will continue to have two customer teams in the championship with all the benefits this brings in terms of technical development within Ferrari," team principal Frederic Vasseur said, referring to the fact that Sauber will switch to works Audi engines in 2026.
However, Ferrari noted that the agreement is contingent upon Formula 1 granting final approval for Cadillac's new team.
In separate developments, the ownership structure of McLaren has undergone a significant change. Previously fully owned by Bahrain, McLaren will now see part of its group - including the Woking based F1 team - acquired by the government of Abu Dhabi.
The deal, signed this week by Crown Princes Salman bin Hamad Al Khalifa of Bahrain and Sheikh Khaled bin Mohamed bin Zayed Al Nahyan of Abu Dhabi, includes Abu Dhabi taking full ownership of McLaren's road car business.
