Cadillac Formula 1 Team has confirmed that a new factory in Silverstone is open as the team develops a broader operating footprint on both sides of the Atlantic.
Speaking in the official FIA team representatives’ press conference at the 2026 Spanish Grand Prix, team principal Marcin Budkowski said the Silverstone site had opened and was not a temporary facility. He also said Cadillac was building facilities in the United States and would develop its presence there progressively.
Cadillac has not disclosed the new factory’s size, capital cost, staffing level, commissioning date or a detailed breakdown of the functions located there. The team’s official recruitment material separately describes current technical roles as being based at its new Silverstone facility.
A permanent UK base for the F1 operation
Budkowski said Valtteri Bottas and Sergio Perez visited the facility on the Tuesday before the Madrid race for technical meetings. His comments establish that the site is operational and being used by the race team, rather than remaining at the planning or construction stage.
Silverstone is listed as Cadillac’s Formula 1 base by the championship, and the team continues to recruit engineering, electronics, manufacturing and operational staff in the area. The new facility gives that workforce a permanent UK operating centre close to the cluster of Formula 1 suppliers and specialist engineering businesses around Silverstone and Northamptonshire.
The disclosure did not identify which departments have already moved into the building, whether all UK functions are now consolidated there or when the site reached full operational status. MRI is therefore treating the confirmed development narrowly: Cadillac says the factory is open and has hosted technical meetings, but has not published a complete facility specification.
US footprint will develop progressively
Cadillac is backed by General Motors and TWG Motorsports and entered Formula 1 in 2026. The programme combines a UK race-team base with engineering and organisational activity in the United States, while GM Performance Power Units is developing a works Formula 1 engine for planned use from 2029.
Budkowski said the team was effectively building facilities in the US and would develop that footprint over time. He did not name the locations in this update, state how many sites are involved or give construction and opening dates.
That distinction matters because the Formula 1 team and GM’s future power-unit business are related but separate operations. The FIA previously said GM Performance Power Units planned a dedicated facility near GM’s Charlotte Technical Center. Cadillac’s latest comments did not say that every US facility under development belongs to the power-unit company, so MRI has not combined the programmes into a single project.
The confirmed Silverstone opening marks a tangible step in Cadillac’s first Formula 1 season. It also reinforces the team’s intended transatlantic structure: an operational base in the UK motorsport cluster, supported by a growing US presence and a longer-term American works-engine programme.
No financial terms, floor area, equipment inventory, headcount target or construction partners were announced. Those details remain undisclosed pending a fuller facility statement from the team.
