Cadillac F1 factory opening date reported

Autosport reported Cadillac plans to open its F1 engine factory on 18 December, ahead of the team’s 2026 debut and GM’s 2029 power unit entry.

Autosport reported that Cadillac plans to open its Formula 1 engine factory on 18 December. With the date not confirmed in the supplied material, it remains a reported timeline as the new team continues preparations for its 2026 entry.

The same report said the facility is being built at General Motors’ base in Charlotte, North Carolina. Autosport also reported that the FIA approved General Motors in 2025 as a Formula 1 power unit supplier from the 2029 season, tying the project to the manufacturer’s longer-term engine programme.

Cadillac F1 Team is due to begin its first Formula 1 season in 2026. Before that debut, the team has no race wins and no constructors’ titles, so the reported factory opening would be another step in building its F1 operation ahead of both its arrival on the grid and General Motors’ planned 2029 engine entry.
