General Motors Engine Officially Approved By The FIA Ahead Of 2029 Formula 1 Entry

American car manufacturer General Motors has been officially accepted as an F1 engine supplier ahead of the 2029 season.

In a t announcement between Formula 1 governing body the FIA and General Motors, a specific year for the team’s entry has been confirmed for the first time.

The new GM team will race under the Cadillac brand, with approval for the team entry being given last month.

Cadillac will debut on the grid next year, using Ferrari engines until their own GM engine is ready in 2029.

At first, the GM entry was rejected by commercial rights holder F1 in 2024, but it has since been approved after being repackaged as Cadillac, rather than Andretti as originally planned.

In order to design and build its own new power unit, GM has set up a new engine company.

A GM spokesperson told BBC Sport that the F1 engine would be ready “by the end of the decade”.

Meanwhile, FIA president Mohammed Ben Sulayem said: “Although the process was at times challenging, the progress we see today affirms the journey has been worthwhile.

“Welcoming GM Performance Power Units LLC. as an approved power unit supplier for the championship starting in 2029 marks another step in the global expansion of Formula 1 and highlights the growing interest from world-class automotive manufacturers like General Motors.”

General Motors F1 Entry Comes As Engine Regulations Debated

The General Motors F1 engine will be designed under the new power unit regulations being introduced from next season.

Running until the end of 2030, the updates specifications will see a new version of the current 1.6-litre turbo hybrid engines.

The turbo hybrids have been in use since 2014, but the new rules will see a simplification of the technology, while upping the proportion of power generated electronically.

This means the battery will create 50% of the engine’s power output, up from the 20% currently produced.

Two weeks ago, F1 engine manufacturers rejected a proposal by Ben Sulayem to bring back the much-loved V10 engines used before 2014.

The idea would have been to reintroduce the V10 naturally aspirated engines, but run them on renewable fuel in order to maintain F1’s commitment to achieving net carbon-neutral status.

While the suggestion was rejected, teams have agreed to continue discussions around future engine rule revisions.

This could see a move back to simpler, cheaper engines before 2029, such as switching to V8s.

But with the new 2026 rules around turbo-hybrid power being a major draw for investment by engine suppliers – including newcomers Audi and GM – any move away from those plans is likely to cause issues among some teams.
