Formula 1 cars will return to the track this week for the first of two pre-season tests ahead of the 2022 season.
All 10 teams will be at Spain's Circuit de Barcelona-Catalunya for what is being billed as a behind-closed-doors test.
There will be no race-style coverage or live timings provided from the event by F1, the FIA or Liberty Media – although RacingNews365.com will be in Barcelona to keep you informed of the events in Spain via our live blog.
The three-day test will comprise six four-hour-long sessions, designed to allow the teams and drivers the chance to shake down their new machines and get an early feel for their cars.
Which teams have already confirmed their Barcelona testing line-up?
So far, eight of F1's 10 teams have - at least partly - confirmed their driver line-ups for this week's first pre-season test of 2022.
Max Verstappen and Sergio Perez will spend one day each behind the wheel of Red Bull's new RB18, with the pair then likely to share track time on Friday.
Mercedes, meanwhile, have opted to keep fans waiting for their Thursday and Friday plans, only confirming that both George Russell and Lewis Hamilton will share track time on Wednesday.
Alfa Romeo are the only team to hand valuable track time to a non-race driver, with Robert Kubica kicking off proceedings on Wednesday morning.
