Ferrari already brought a new software for the energy management system in Monaco, after some suspects surfaced from Mercedes and other teams.
The irregularity was suspected to consist in a sudden increase of speed in Baku’s Qualifying (read more about it here). Thanks to the conformation of the battery, a two segments system that only Ferrari uses, it would be possible to avoid the measurement of the energy supplied in certain moments.
After a request from both Mercedes and Renault, the FIA then checked the system in Baku and Barcelona, but no irregularity was found, and the Federation gave the team the greenlight.
Anyway, Ferrari came in Monaco with a new version of the software, giving some hints that maybe there were some irregularity. The suspicious, though, will never find an answer: if the FIA couldn’t find anything on the actual software, it would be even more difficult from other teams from the outside to make officials accusation to FIA’s International Court of Appeals and prove them.
The fact that everyone looks at what Ferrari does and how they do it, means that the Italian team, regular or not, has some big chances by its side for the championship. Anyway, things like this should not happen, as recalled by Renault’s Team Principal Cyril Abiteboul: “We need a simpler technique in Formula One. If even the FIA has trouble finding the mistake, we are on the wrong track.”
The only way this case can go on is submitted to FIA President Jean Todt will, or if another team asks him to do it, but again, it would be very hard to prove it.
