Many F1 teams are taking part in track days as the new season draws nearer, as they get back into a rhythm and practice new safety protocols implemented amid the ongoing coronavirus pandemic.
Renault concluded a two-day test at the Red Bull Ring on Wednesday, while Mercedes was at Silverstone last week - both teams ran with their 2018 cars, as the regulations stipulate a car that's at least two years old must be used when testing outside of official F1 sessions.
Despite the restrictions, Sainz and Norris have managed to go testing in F3 cars run by Carlin at a very wet Silverstone Circuit on Thursday.
McLaren is aiming to retain its position as the leading midfield team this year, having ended the 2019 campaign in fourth place.
