Ferrari's strong form at Silverstone a fortnight ago renewed focus on the progress the team has made with its car, and even prompted extra intrigue about a potential 'free' energy trick it has up its sleeve.
But rather than this being the start of a fresh cheating controversy, it instead appears that the boffins at Maranello may be doing something very clever to exploit a freedom in the rule book.
Ferrari was certainly in a gloating mood after Sebastian Vettel's victory in the British Grand Prix. On Lewis Hamilton and Mercedes' home soil, and at a Silverstone track that had previously favoured the Silver Arrows, Vettel and Ferrari wasted little time in rubbing salt into their rivals' wounds.
