9 of the 10 teams have confirmed their driver line-ups for the three days of testing to come in Bahrain from Friday to Sunday. 

World Champions Mercedes have decided to give Valtteri Bottas the first run in the W12 tomorrow morning, with seven-time World Champion Lewis Hamilton getting his first taste of the new car in the PM session. 

Max Verstappen, Daniel Ricciardo, Sebastian Vettel, Esteban Ocon, Charles Leclerc, Pierre Gasly, Kimi Raikkonen and Mick Schumacher are the other drivers on the 2021 grid who’ll join Bottas on the circuit tomorrow morning.  

Lando Norris, Lance Stroll, Carlos Sainz, Yuki Tsunoda, Antonio Giovinazzi and Nikita Mazepin jump into their respective cars for the PM session.  

Williams’ test driver and DAMS Formula 2 driver Roy Nissany gets a full day of running tomorrow, along with Verstappen and Ocon. He’s the only reserve or test driver to get the opportunity to complete some laps in winter testing.  

Sergio Perez's first appearance for Red Bull in front of the world comes on Day 2 of the test.

With just three days of testing before the season-opener in just over two weeks, every team on the grid bar Williams has decided to split the running on at least one of the days to come. Reliability is going to be even more critical because of the testing reduction.
