Lewis Hamilton stepped into Ferrari’s iconic red for the first time at a private test in Fiorano on Wednesday.

According to reports from Italian outlet Corriere Della Sera, Hamilton “called Vettel on the phone in recent weeks to prepare for his first day” at Ferrari.

Vettel, a former Ferrari driver, was Hamilton's rival throughout his Red Bull Racing years and later during his time in Rosso Corsa.

Although the two multiple world champions were rivals across different eras, the pair became friends, with Hamilton recently calling him his greatest “ally” and “the best world champion” he knows.
