F1 set for engine changes in 2027 as debate over V8s returns

Formula 1's stakeholders are moving to address problems that emerged with the new V6 hybrid power units introduced for 2026. A small set of tweaks in Miami already restored some of the qualifying spectacle, and further changes are being planned for 2027 to rebalance the power split between the internal combustion engine and the hybrid system.

Agreed in principle for next year is a 50 kW (67 hp) increase to the V6, with the electric motor able to deploy 50 kW less, shifting the balance to 450 kW from the V6 and 300 kW from the motor-generator unit. The extra V6 output will come via higher fuel flow, which should keep the battery at a higher state of charge around the lap and reduce the speed differentials created when the system resorts to super clipping.

Further items still under discussion include raising the amount the electric motor can harvest from the V6 above 350 kW and increasing battery capacity from 4 MJ to 5 MJ. Those changes carry trade-offs.
