F1 fans spot key detail in first footage of Lewis Hamilton's Ferrari testing as Frederic Vasseur speaks out

F1 fans have spotted an interesting detail after watching Lewis Hamilton and Charles Leclerc's first laps in the Ferrari SF-25.

The Scuderia unveiled their 2025 car, alongside all other nine teams, during the F175 launch event at London's O2 Arena on Tuesday.

Leclerc and Hamilton have already completed testing programmes in previous cars as part of F1's Testing Previous Cars (TPC) regulations, but drove their new Ferrari on track for the first time in Maranello on Wednesday.

Leclerc completed 100km of testing in the morning, with Hamilton taking over driving duties in the afternoon.

Gazzetta dello Sport claim that Leclerc had a minor problem with his car in the morning, but was able to continue his session quickly after his team identified the issue in the garage.

Official pre-season testing takes place in Bahrain next week over three days, but the first run at the team's own test track will allow them to iron out any early issues before then.

Now, footage of the test session has emerged on social media.

Fans have already spotted one notable difference between Hamilton and Leclerc's laps, noticing that the Monegasque driver took corners slightly differently.

In Leclerc's footage, he eased the car more slowly away from the inside curb, whereas Hamilton was quicker to move to the outside curb on corner exit.

While only a minor difference, it will provide Ferrari with an early indication of how to set up both cars in their own individual way to suit each driver at the season-opening Australian Grand Prix next month.

Speaking to Sky Sports, Ferrari team principal Frederic Vasseur expressed his optimism over the Scuderia's early progress.

He said: "From a technical point of view, the on-track testing was good.

"The battle was tough last year, and there was no need for a revolution [to the car].

"Hamilton was excited yesterday in London, but he has been for a while.

"On paper, we are [one of] four teams capable of fighting for the title, then after the first Grands Prix we will see how things are."
