Cadillac commits to F1 engine supply from 2028 with Andretti

General Motors has announced plans for its Cadillac brand to design and build engines for Formula 1 racing from the 2028 season onwards.

The commitment represents a significant boost for Michael Andretti's bid to enter a new team, in partnership with Cadillac, on the F1 grid in the coming years.

The American automotive giant revealed Cadillac's future F1 involvement ahead of this weekend's Las Vegas Grand Prix, marking another milestone for the championship's expansion in the United States.

While no firm entry date has been set, Andretti is pushing for a 2025 start, which could potentially be pushed back to 2026.

Either way, Cadillac becoming an F1 power unit supplier in 2028 would necessitate Andretti source interim engine supply from 2025-2027 if accepted onto the grid.

Renault is the most likely candidate, with Andretti having already initiated discussions last year before the French marque's management change.

Per F1's regulations, Renault would be obligated to supply Andretti as the manufacturer with the fewest existing customer teams.

Come 2026, Renault, Honda and Audi would each supply one works squad, opening the door for Andretti to negotiate with any of them until Cadillac comes on board.

The Cadillac announcement strengthens Andretti's bid credibility after receiving approval from F1's governing FIA, but still awaiting consent from F1's commercial rights holders.

Michael Andretti formed a partnership with General Motors and the Cadillac brand in 2022 to enhance the viability of his entry proposal.

Cadillac will join existing 2026 F1 power unit suppliers Mercedes, Ferrari and Red Bull Powertrains, plus new entrant Audi, in developing Electrical Power Units comprising 50% electrical energy under new engine regulations.

Andretti aims to bring a truly competitive American team to F1's expanding US footprint.

The confirmation of Cadillac as a future engine supplier adds important manufacturer backing and technical firepower to achieve that vision.

With the FIA onboard and now concrete confirmation of Cadillac's long-term F1 participation, Andretti's bid to shake up the grid continues gathering momentum.

The prospect of Andretti-Cadillac competing in F1 fast approaches reality.
