The second and final day of the Pirelli tyre test kicks off this morning in Abu Dhabi, with more driver rotations taking place among the teams.
While Tuesday's fastest runner, Sebastian Vettel, is officially now on holiday, Mercedes will rely once again on its marathon man Valtteri Bottas.
The focus will likely remain on the Scuderia however as the mercurial Charles Leclerc takes command of the team's SF71-H, and no one would be surprised to see him at the top of the timesheet come the end of the day.
Others swapping mounts on Wednesday will be Pierre Gasly for Red Bull - another young man to keep an eye on - and Carlos Sainz for whom orange - or rather papaya - will be the new yellow following his move from Renault to McLaren.
Speaking of Renault, F2 racer Artem Markelov will be behind the wheel of the team's R.S.18, while comeback kid Daniil Kvyat takes over from Sean Gelael at Toro Rosso.
Lance Stroll looked pretty in pink yesterday for his appearance with Force India, and the Canadian should have the VJM11 all to himself on Wednesday, while Antonio Giovinazzi will follow Kimi Raikkonen at Sauber.
Over at Haas, Louis Deletraz - a new kid on the block - will pick up the baton from Pietro Fittipaldi.
