Thꩲe FIA has ended its investigation into Ferrari’s use of its energy recovery⭕ system (ERS) on its SF71H Formula 1 car after being “satisfied” by its findings over the Monaco Grand Prix weekend.

It emerged on Thur💜sday that the FIA had fitted a new piece of hardware to Ferrari’s ERS during practice in Monaco following questions raised about its usage amid suggestions the Italian team had found a way to excܫeed the maximum permitted energy usage.

Bosses from rival teams Red Bu🍨ll a𓆉nd Mercedes welcomed the investigation, but FIA race dir💛ector Charlie Whiting confirmed on Saturday that F1’s governing body had been “satisfied” by its findings, bringing🅠 its investigation to a close.

“We had some concerns in Baku that were difficult to explain and we worked through it with them,” Whiting said in a media briefin🎉g attended by both and  in ꦍMonaco.

“In Spain, Ferrari showed us things that helped satisfy us that they wꦛere insideꦇ the rules. We first looked at data, digging quite deep. We had to understand whether Ferrari’s explanations were valid.

“We were never in doubt that things were above board, but by Friday night weꦇ were convinced. We have some pretty clever guys working for us now to spot thi🍌s kind of thing.

“It is the duty of t📖he competitor to satisfy the FIA that their car complies at all times and they were having difficulty satisfying us. Here, we are now satisfied.”

Whiting went on to explaiꦗn how the issue had escalated following speculation through the F1 paddock, but called the allegations against Ferrari “unsubstantiated”.

“It came from a Ferrari engine man n🦄ow at Mercedes, but his information would be the length of his gardening leave old,” Whiting said.

🐷Vettel will start Sunday’s Monaco Grand Prix from P2 on the grid behind Red Bull’s Daniel Ricciardo, with Mercedes’ Lewis Hamilton set to line up third.
