Formula 1’s governing body the FIA say they have reached a “settlement” with Ferrari following a long-running analysis into the Italian team’s 2019-spec power unit.

Ferrari’s power unit emerged as the class of the field in 2019, the red cars of Sebastian Vettel and Charles Leclerc displaying a power advantage over their rivals and enjoying impressive straight line speed.

Their rivals had theories about how they were gaining that advantage – but never launched a formal protest. A series of technical directives were issued clarifying the situation and a new double fuel sensor regulation put in place.

Ferrari’s team boss Mattia Binotto consistently denied any wrongdoing and the team were not found to have broken the regulations.

“After thorough technical investigations, it [the FIA] has concluded its analysis of the operation of the Scuderia Ferrari Formula 1 Power Unit and reached a settlement with the team,” read the statement. “The specifics of the agreement will remain between the parties.
