When the lights go out Sunday in Melbourne to start the Australian Grand Prix, the Formula 1 season will begin in earnest. The grid will look vastly different from a year ago, with several new faces in new places. However, none of those changes are bigger than Lewis Hamilton’s move to Ferrari.

After an off-season of several driver changes, the 2025 F1 season begins Down Under with Mr. Hamilton wearing new colors. He had previously driven for Mercedes for 12 seasons, during which time he won six of his seven world championships, making him the most decorated driver in Formula 1’s history.
