Antonelli then went on to complete sessions at the Mexico City Grand Prix and in the Abu Dhabi post-season test as the Italian took every opportunity to acclimatise to his Mercedes.

Antonelli shows skills in “crazy” Mercedes outing
With the 2025 season fast approaching, Antonelli blew off the cobwebs in Stuttgart by putting the G 580 and GT 63 Pro through their paces.
Mercedes tagged the video, quipping: “Things you don't learn at driving school.”
Antonelli was shocked by the Mercedes 'power'
Clearly loving the experience, the beaming teenager is heard saying: “That’s a lot of power” and "that’s crazy” as he got acquainted with the throttle on both cars.
Antonelli will be present alongside team-mate George Russell for the official F1 launch at The O2 on February 18 before pre-season testing in Bahrain eight days later.
He will make his official debut at Australia’s Albert Park circuit from March 14.
