In an effort to make F1 more open to the media and fans, the FIA introduced new procedures last year to increase the transparency of the latest developments brought to each race.

As part of revised sporting regulations, teams now have to notify the FIA in advance of each grand prix weekend about any new "major aerodynamic and bodywork components and assemblies" that are intended to be run.

But as well as having to explain in writing what they have done, the regulations also force teams to display these parts prior to the start of first free practice for what has become known as a 'show and tell' session.

During a designated window ahead of FP1 on Friday, teams are supposed to make their cars available outside the designated garage area, where the media can get up close to see the new parts.

However, there were times during 2022 when teams pulled off a sly trick in trying to hold back showing off too much of their designs.

If the parts were fitted only to one car for first practice, then occasionally some squads would keep that car in the garage where items could not be spotted, and roll out the more standard version for public display.

Such a practice went against the intention of the regulations in getting the latest tech more on show, and the FIA has duly responded for the 2023 season.

In revised regulations published ahead of the first race in Bahrain, the FIA has made it clear that teams must display the latest parts on the car that is rolled out of the garage.

The new rules state: "If only one car will carry the major aerodynamic and bodywork components and assemblies that have not been run at a previous Competition or TCC [testing of current cars] and are intended to be run at the Competition, this car must be the one displayed to media."

As well as the teams having to explain the developments on their cars, the FIA has also moved to ensure more visibility in terms of engine progress.

The sporting regulations now demand that each car manufacturer must hold a briefing once per year to talk about their engine.

"Each registered Power Unit Manufacturer must be available at one (1) Competition during the season to give a media presentation for a duration of at least 30 minutes," states the rules.

Lewis Hamilton says Mercedes didn’t listen to his feedback about what he needed from the 2023 car and has to take responsibility for its lack of performance this season.

Mercedes was nearly a second per lap off the pace of Red Bull in race trim on Sunday in the Bahrain Grand Prix, with Hamilton finishing fifth behind Max Verstappen, Sergio Perez, Fernando Alonso and Carlos Sainz. With Mercedes arguably the fourth-fastest team despite sticking with its zero sidepod car concept, Hamilton says his comments were not taken on board.

“Last year, there were things I told them,” Hamilton told the BBC. “I said the issues that are with the car. I’ve driven so many cars in my life so I know what a car needs, I know what a car doesn’t need. I think it’s really about accountability.

“It’s about owning up and saying, ‘Yeah, you know what? We didn’t listen to you. It’s not where it needs to be and we’ve got to work.’ We’ve got to look into the balance through the corners, look at all the weak points, and just huddle up as a team. That’s what we do.

“We’re still multi world champions, you know? Just haven’t got it right this time. Didn’t get it right last year. But that doesn’t mean we can’t get it right moving forwards.”

After just a single grand prix in 2023, Ferrari appears to be in turmoil.

La Gazzetta dello Sport reports that Charles Leclerc asked for a face-to-face meeting with the Italian company's executive chairman John Elkann after the disappointing Bahrain GP.

At the same time, rumours of conflict between Ferrari's new team boss Frederic Vasseur and CEO Benedetto Vigna have emerged.

Corriere dello Sport claims Frenchman Vasseur is alarmed to find that Vigna has taken on some of the responsibilities of the axed Mattia Binotto.

For instance, Vasseur is apparently finding that he has little control over personnel decisions or dealings with team sponsors.

"Vasseur wanted to sign a new sponsor, but he was stopped by the leadership at Ferrari," a source said.

It could be why he chose not to travel to Bahrain with other Ferrari team members, but instead with his friend Toto Wolff.

La Gazzetta dello Sport also reports that Ferrari's sporting director Laurent Mekies is keen to join the team exodus, after it emerged last week that aerodynamics chief David Sanchez is heading to another team.

Frenchman Mekies' destination could be the Stefano Domenicali-led Formula 1 organisation - but it is believed Vasseur has stepped in to veto the move.

"Vasseur has used his right of veto and now there is an impasse," the report read.

La Gazzetta dello Sport also claims that Ferrari's executive race manager Jonathan Giacobazzi and long-time familiar face Gino Rosato have departed - together with strategy boss Inaki Rueda.

Corriere della Sera claims that more departures may be imminent.

"Several contracts will expire soon, including that of Enrico Cardile, who acts as technical director," the newspaper said.

"No one is in a safe place."

Ralf Schumacher, whose brother Michael is the most successful Ferrari driver in history, thinks the team's current problems can be dated back to the Sergio Marchionne era.

"There's just a certain legacy at Ferrari and it's not the current president's fault," he told formel1.de. "It goes back to the former boss, who also brought Alfa Romeo back.

"It was his idea to make Ferrari an all-Italian team again and go back to that DNA. But I think they overlooked a lot of things in that process."
