Cars racing in the 2027 and 2028 Formula 1 seasons will be getting more combustion power after the series recently agreed on a revised set of power regulations. In the current season, F1 cars use hybrid systems that split power delivery by 53% and 47%, respectively, between the internal combustion engine (ICE) and the kinetic motor generator unit (MGU-K).
Four-time champion Max Verstappen has consistently expressed his disdain for these powertrains, recently calling the current format “Formula E on steroids.” Those big words seem to echoe the sentiments of other teams, as F1 will be allowing more combustion power in the next two seasons.
Specifically, the 2027 season will see a 58% and 42% split between ICE power and the MGU-K, while the 2028 tournament will go even further with a 60% and 40% split. Naturally, this means less output from the electric units and more horsepower from the engines.

Right now, the combustion engines in F1 cars are limited to 536hp, but in 2027, that will be increased to 563hp, and then to 603hp in 2028. On the electric side, maximum power in 2027 and 2028 will be lowered to 402hp, dropping from the current 469hp.
In overtake mode, peak output will remain at 469hp; however, harvesting power will gradually increase throughout the next two seasons. Harvesting refers to the regeneration or recovery of energy to the MGU-K, which should help in acceleration at a later time. Currently, it is limited to 469hp, but it will increase to 503hp in 2027, and then 536hp in 2028.
While F1 has agreed to the new amendments, these are still up for approval by the World Motor Sport Council. On June 23, these will be submitted to the council, but it is unclear when exactly a decision will be published.
