F1 2027: Engine Power Split to Shift Dramatically
14 May
Summary
- Formula 1 plans to alter engine hardware for 2027.
- ICE power will increase to 60%, reducing electrical systems to 40%.
- Manufacturers face redesign costs under existing budget caps.
Formula 1's stakeholders are nearing an agreement for substantial engine hardware changes set to take effect in the 2027 season. The proposal involves altering the power delivery split, moving from the current near 50-50 balance between the internal combustion engine (ICE) and electrical systems to approximately 60-40, with the ICE gaining prominence. This will be achieved by increasing the permitted engine fuel flow and lowering the electrical energy output. Manufacturers like Audi, Ferrari, Honda, Mercedes, and Red Bull-Ford will need to adapt their designs, presenting a potential cost challenge under the current $190 million budget cap for 2026. Teams are considering chassis redesigns to accommodate these altered engine parts. The potential for increased cost caps for manufacturers and teams is being debated to facilitate these significant changes and address driver criticisms of the current 'anti-racing' engines. Discussions are also ongoing regarding the Additional Development and Upgrade Opportunities (ADUO) system, which aims to equalize engine performance across the grid, as manufacturers await formal decisions by June 23.
