Allison says FIA aims to return 2027 F1 downforce to early-2026 levels

Formula 1 teams have only just got to grips with their 2026 cars, but another significant technical change is due in 2027. Mercedes technical director James Allison says the FIA has worked to reduce downforce to the level seen at the start of 2026.

The power-unit split between the combustion engine and electric motor is also set to change, from 53/47 in 2026 to 58/42 in 2027 and 60/40 in 2028. The chassis will be revised too, and Allison describes the changes as far more than a minor adjustment.

Whether teams accept the downforce reduction or manage to recover it fully remains to be seen, Allison said.
