The discussion about the Formula 1 engines for 2027 has gained a new chapter, with Cadillac ready to follow Ferrari’s position in a possible vote on regulation changes. The decision could be decisive for the future of power units and for the implementation of changes already discussed between the FIA and manufacturers.

The topic involves the power distribution between the combustion engine and the electric part. Currently, there is a principle agreement to change the planned 50% split for each system, moving to a ratio of approximately 60% for the combustion engine and 40% for electric energy from 2027 onwards.
The proposal aims to reduce the need for excessive energy management during races. The expectation is that drivers will need to ease off the throttle less to recharge the batteries throughout the lap, favoring more aggressive battles and placing greater emphasis on the combustion engine’s performance.
However, Ferrari and Audi surprised some involved by advocating that this change be postponed to 2028. The two manufacturers do not oppose the change but consider that an additional year of preparation would be the most appropriate scenario before the definitive implementation of the new concept.

Cadillac’s position was unknown until then. According to the information released, the American manufacturer will follow Ferrari’s vote as it is currently a customer of the Italian team’s engines. Thus, if Ferrari approves the change for 2027, Cadillac will also support the proposal. If the Italians reject the early implementation, the American brand will adopt the same stance.
On the other side of the debate, Mercedes, Red Bull Powertrains-Ford, and Honda support the introduction of the new power split already in the next season. Honda, in fact, has shown no resistance to the change to the 60% combustion engine and 40% electric energy ratio, aligning with the interests defended by other manufacturers and also by several drivers.
For the change to be approved, a supermajority among those involved is required. This means that five of the six manufacturers, in addition to the FIA and Formula One Management (FOM), need to agree with the proposal. With Audi maintaining its preference for 2028, Ferrari’s decision has become a central piece of the process. Still, negotiations continue, and there is the possibility of a compromise capable of gathering enough support to enable the changes already in 2027.
