The US car maker will use Ferrari engines when it lines up on the 2026 starting grid.
Ferrari engines will be used to power Cadillac’s F1 team in a supply deal starting in 2026, when the US car maker will make its debut.
Luxury brand Cadillac – owned by US car giant General Motors – was confirmed as a new entry from the 2026 Formula One (F1) season, making it the 11th team, growing the number of cars competing to 22.
Officially a “multi-year agreement” with no specific dates, Ferrari is expected to power the Cadillac entries its first two seasons only – meaning 2026 and 2027 – but may be used until 2030.
Using a ‘customer engine’ is common in F1, with Ferrari engines powering six cars across three teams in 2024 – the Sauber F1 team, Haas F1 Team as well as Scuderia Ferrari itself.
The move gives Cadillac time to develop its own power units which it said in a statement it plans to move to “by the end of the decade”.
It means from 2030 Cadillac will be responsible for its own chassis as well as its engines – an expensive and daunting challenge only two F1 teams currently racing manage.
Scuderia Ferrari makes both its chassis and engine – the complete car – with Mercedes-Benz the only other team doing so.
Mercedes-Benz also powered McLaren in 2024 – which included Australian driver Oscar Piastri’s first two Grand Prix wins on the way to winning the constructors title – as well as the Williams and Aston Martin teams.
A sweeping regulation change in 2026 has enticed new entries such as Cadillac onto the grid, given the significant time and cost required to develop a competitive F1 car for a given rule set.
German manufacturer Audi will also officially be on the 2026 grid, too, having bought Sauber in preparation in 2022.
The world’s largest car maker, Toyota, became a technical partner with Haas F1 Team in late 2024, giving the Japanese brand – hugely successful in sports car racing – a presence in F1 for the first time since 2009.
