The Ferrari reserve driver was promoted to the F1 earlier in March to deputise for Carlos Sainz.

Bearman put in an impressive drive in the Australian sprint race, rising from starting 16th to cross the line in eighth.
However, after the race, the teenager was docked with a brutal ten-second penalty.
That is because Bearman forced rival Joshua Durksen off the track at turn four, sending the Paraguayan-German driver into the gravel.
And that saw the Brit plummet down to 14th, wiping out Bearman’s first F2 point of the season as he remains on zero – alongside three other of the 22 drivers – as he eyes a seat in F1 for 2025.
He was also hit with two penalty points on his super licence.
