The 2022 Formula 1 season is not yet underway, yet there are quite a few experienced drivers fighting for their future.
Perez set the fastest time on Pirelli's C4 compound tyres, as Red Bull appeared to shift its focus to performance ahead of next week's race.
Gasly set a time of 1:33.902, replacing Ferrari's Charles Leclerc at the top who went fastest in the first session.
The Frenchman believes that 2023 might be his last chance to reach the front of the grid with Red Bull.
The AlphaTauri F1 team managed to put up a respectable 308 laps during the three-day testing session at Barcelona.
Yuki Tsunoda often struggled during his rookie season in 2021 and was easily outpaced by AlphaTauri teammate Pierre Gasly.
Tost is of the opinion that the new set rules introduced by the FIA will restrain the cars from producing high-speed in the 2022 season.
Pierre Gasly was arguably one of the most consistent driver's in Formula 1's crowded midfield in the 2021 season.
AlphaTauri driver Pierre Gasly believes whatever he chooses to do in the 2023 F1 season will be a 'key move' for his career.
Tsunoda's highest finish in F1 was P5 in Abu Dhabi, but he only outqualified Gasly once all season and was frequently far behind in races.
