Formula One engines set to undergo another change in 2027.

Formula One officials have addressed criticism of this season’s power unit changes by committing to “further evolutionary adjustments” ahead of a full overhaul planned for the 2027 season, the FIA confirmed on Friday.

Motorsport’s governing body announced that the 11 team bosses and five power unit manufacturers have reached an agreement in principle to bring back the dominance of combustion power over electric power as soon as 2027.

The FIA announced that, starting in 2027, internal combustion engine power will get a nominal boost of 50 kilowatts alongside an increase in fuel flow, while the energy recovery system’s deployment power will be reduced by 50 kilowatts.

This decision, which still has to be discussed in detail let alone approved, would in effect put an end to the 50/50 parity in hybrid engines —- half electric, half combustion — introduced this season by the FIA.

The new regulations have made racing more thrilling for fans, but drivers have had mixed reactions. Four-time champion Max Verstappen even called it “Formula E on steroids” and hinted he might leave Formula One if things don’t change.

The 50/50 system involves a complex management of the battery during overtakes and then during the necessary recharging of electrical energy when slowing down and braking.

This has triggered safety concerns, notably when Oliver Bearman had a dramatic crash at the Japan GP as he closed on Alpine’s Franco Colapinto.

The significant difference in speed between the two cars as a result of their contrasting states of energy deployment led to Bearman taking evasive action and hitting the wall.

Last month, the FIA announced a new “adjusted” version of the regulation which came into play at last weekend’s Miami GP.

Friday’s meeting gave the thumbs up to the modifications, saying they had improved competition and were a “step in the right direction”.

The FIA said they would look at “further adjustments at future events”, possibly as soon as the next grand prix in Canada on May 24.
