General Motors (GM) to Join F1 with Cadillac Brand in 2026

General Motors (GM) has reached an agreement in principle to enter Formula 1 in 2026 under its Cadillac brand. GM in partnership with US group TWG Global will field a new team named after Cadillac and plans to develop its own engine, although it will not be ready until 2028. In the meantime, the team will likely source an engine from an existing supplier, with Ferrari currently the favored option. F1’s commercial rights holder, Liberty Media expressed excitement about GM and Cadillac’s entry, noting that it would boost the sport’s growth in the US.

F1 CEO Greg Maffei emphasized GM’s potential as both a team owner and future power unit supplier, believing that it would bring additional value to F1. FIA President Mohammed Ben Sulayem also supported the move, highlighting the importance of collaboration to ensure the entry’s success. GM’s entry involves an anti-dilution fee of $450 million which the existing F1 teams will share as compensation for the prize money they will lose by splitting F1’s income between 11 teams instead of 10.

This fee exceeds the typical $200 million anti-dilution fee, reflecting the new contract negotiations for 2026. The Cadillac team will replace the previously rejected Andretti bid with General Motors (GM) now entering as the team owner. Dan Towriss and TWG’s Mark Walter are key investors in the project with Michael Andretti, who stepped down from Andretti Global, no longer involved.

GM’s entry will increase the number of manufacturers building F1 engines to six alongside Mercedes, Ferrari, Ford, Honda and Audi. With the new hybrid engine regulations set for 2026, GM, Ford, Audi and Honda will join F1 as new entrants contributing to an exciting future for the sport.
