Formula 1 made a series of changes to the regulations governing power units for last weekend's Miami Grand Prix
Formula 1 bosses have agreed a change to engine design for the 2027 season in response to criticisms of the new power units introduced this year.
Drivers have complained that the near 50-50 split between internal combustion and electrical power and need for energy management has diminished the challenge in qualifying.
It was agreed in principle in a meeting of teams, commercial rights holder F1 and governing body the FIA on Friday to increase the proportion of total power coming from the internal combustion engine by 50kW (67bhp) and reduce the electrical power by the same amount.
This effect of this should be for drivers to be able to drive in a more conventional way in qualifying.
