Since 2018, teams have been raising questions about Ferrari’s power unit, looking for FIA clarifications on whether it could be in breach of the rules in its use of a twin battery; by burning excessive oil; or by interfering with the standard fuel flow meter.
Suspicions intensified when Charles Leclerc’s car was checked before the end-of-season Abu Dhabi Grand Prix, and found to have 4.88kg more fuel than the team had declared. Ferrari incurred a €50,000 fine.
The settlement immediately drew speculation over what prompted Ferrari to make its additional commitments to the FIA.
This year’s engine does not have an obvious power advantage over the rest of the field, based on the results of six days of testing.
