Formula 1 has finalized a two-stage plan to recalibrate its engine regulations, shifting the power balance toward internal combustion engines (ICE) to resolve driver complaints regarding energy management. According to the FIA, the move will adjust the power split to 58-42 in 2027 and reach a 60-40 ratio by 2028, effectively ending the current near-equal power distribution that forced drivers to coast during qualifying laps.
Why are Formula 1 engines changing?
Drivers criticized the current power unit regulations for being overly reliant on electrical energy, which resulted in “energy-starved” cars. According to reports from the FIA, the reliance on harvesting energy meant that drivers were lifting off the throttle during qualifying to manage power reserves. Four-time champion Max Verstappen expressed significant frustration with the current state of the engines, while other drivers reached a consensus that the “flat-out” nature of qualifying had been compromised. By increasing the fuel-flow to the ICE by 5% in 2027 and 13% by 2028, the governing body aims to restore the traditional racing feel without sacrificing the excitement generated by the current technical era.
How does the power output shift work?
The transition involves a calculated reduction in electrical power alongside a boost in combustion output. Current internal combustion engines produce approximately 400kW (536bhp), a figure set to rise to 420kW (563bhp) in 2027 and 450kW (603bhp) by 2028. Conversely, electrical power will drop from the current 350kW (470bhp) to 300kW (402bhp) starting next year. According to technical documentation, while the maximum “overtake mode” power remains constant, the maximum harvesting power will increase to 400kW by 2028, allowing teams to recover energy more efficiently and reduce the time spent in energy-recovery phases.
Fernando Alonso described the current generation of F1 cars as having fast corners that effectively act as “charging stations” rather than traditional racing turns, highlighting the extreme focus on energy recovery over pure speed.
What is the current hierarchy of engine performance?
The FIA has established a ranking of power unit performance to allow manufacturers to close gaps of more than 2%. While the governing body has not released an official public list, sources indicate that Red Bull currently leads the field in ICE power. Under the new rules, manufacturers are permitted to spend additional funds under the engine budget cap to implement upgrades. Mercedes has been granted one upgrade for the current season and one for next year, while Ferrari, Audi, and Honda are permitted two upgrades in both 2027 and the current season. Notably, Honda was categorized as the furthest behind, falling into the 8-10% deficit bracket, which excluded them from a potential $19 million (£14 million) funding injection reserved for those more than 10% off the pace.
How does this affect the future of F1 racing?
The compromise, reached after a month of negotiations involving Ferrari and Audi, prioritizes technical stability. Manufacturers had pushed back against a single-step transition for 2027, favoring the two-stage approach to manage development costs and engineering complexity. This regulatory shift represents a move to balance sustainable technology with the demands of drivers who want to push their cars to the limit for the duration of a qualifying session. The success of this change will be measured by whether the “lift-and-coast” behavior observed in the early races of this season is eliminated in the coming years.
Frequently Asked Questions
- Why were drivers unhappy with the engines? Drivers felt the 50-50 power split forced them to coast and manage energy during qualifying rather than driving at full speed.
- When will the power split change? The ratio will move to 58-42 in 2027 and reach 60-40 in favor of the internal combustion engine by 2028.
- Can engine manufacturers upgrade their power units? Yes, the FIA allows manufacturers to implement performance upgrades if they are more than 2% behind the most powerful engine, provided they stay within the engine budget cap.
- Who has the most powerful engine currently? While the FIA does not publish official rankings, sources report that Red Bull is currently considered to have the most powerful internal combustion engine.
