A change in Formula 1 regulations this year has seen the sport move from 13-inch wheels to 18-inch ones.
This has made the tyres heavier and thus more difficult for mechanics to change all four of them quickly and safely during pit-stops.
A rule change halfway through 2021 changed the pit-stop procedure, making it even more difficult for mechanics to complete a lightning fast stop.
However, at the Mexico City Grand Prix, McLaren became the first team to complete a sub-two second pit-stop since the introduction of the new regulations, changing all four tyres on Daniel Ricciardo's car in 1.98 seconds.
So how did McLaren manage to do this? In our latest video, RacingNews365.com takes a look at the changes that have been made to F1's pit-stop procedure in the last couple of years.
