How Leclerc blew another wet tyre call while Sainz nailed it · RaceFans

The British Grand Prix was the most recent in a collection of rain-affected occasions the place one Ferrari driver known as the situations appropriately and the opposite blew it.

Charles Leclerc was left to depend the price of a hasty swap to intermediate tyres when rain started to fall at Silverstone.

His workforce mate Carlos Sainz Jnr, in the meantime not solely averted that mistake however selected arguably the proper lap to change to intermediates, taking round two seconds out of eventual winner Lewis Hamilton consequently.

That is the most recent in a collection of expensive errors Leclerc and his race engineer have made in unpredictable moist climate situations. It’s the first since Bryan Bozzi changed Xavier Marcos Padros because the voice in Leclerc’s ear.

In Sochi three years in the past Leclerc, having made up 15 locations to run fourth when rain arrived, dedicated the identical error as race chief Lando Norris by staying out on slicks tyres too lengthy when rain arrived. That duff name left him out of the factors on the finish of the race, whereas Sainz got here in for intermediates earlier and bagged a podium end consequently.

The next 12 months Leclerc threw away a possible win in Monaco with an pointless tyre change on a slowly drying monitor. Ferrari needed each drivers to switch their worn intermediate tyres with recent units, however Sainz overruled them and remained on-track till the situations had been dry sufficient for slicks, transferring him forward of his workforce mate. Leclerc’s plight worsened when he misplaced extra time pitting behind Sainz later within the race, however the preliminary name had already set him on track to lose victory.

Related calls have caught Leclerc out in qualifying classes. Later in 2022, as rain threatened at Interlagos throughout Q3, the Ferrari drivers once more opted for various tyres. Leclerc was the one driver within the session to move out on intermediates and missed his alternative to set a time on slicks when the monitor was dry sufficient. The same state of affairs occured throughout Q2 in Canada final 12 months.

At Silverstone final weekend the distinction between the data the Ferrari drivers obtained was stark. Sainz was given detailed steerage on the degrees of rain at completely different components of the circuit, whereas Leclerc’s info was much less frequent and detailed. This led him to a different expensive tyre selection error.
