Nothing in sport is quite like an F1 pit stop: a stationary car, twenty people, four wheels, and it is all over before you have finished reading this sentence. Two seconds is now routine; the very best stops dip under that. But the stop itself is only the visible tip of a process that involves choreography, engineering and a surprising amount of rulebook. Here is how it all works.

Who does what in the crew

A modern pit crew involves around 20 people, each with a single job:

  • Wheel gunners (four): one per corner, operating the pneumatic gun that removes and re-fits the single central wheel nut.
  • Wheel-off and wheel-on mechanics (eight): one pulls the old wheel away, one fits the new wheel — two people per corner.
  • Front and rear jack operators: lift the car within a fraction of a second of it stopping. Rear jacks are often lever-operated; front jacks swing aside to let the car go.
  • Stabilisers: steady the car on its jacks so the gunners get a clean shot at the nut.
  • Front-wing adjusters: if the driver needs a change in front-wing angle, mechanics wind it while the tyres are changed.
  • The crew chief: controls the release, confirming all four corners are done before the car is dropped and the light goes green.

The sequence, second by second

The driver stops on precise marks painted in the pit box. Front and rear jacks go on immediately. The four wheel guns fire, four wheels come off, four go on, the guns fire again. Each gunner signals completion — in modern systems, sensors in the gun register the nut’s torque and trigger the release automatically — and the car is dropped. The driver watches a traffic-light gantry: red while the work continues, green when it is safe to leave. The whole choreography is rehearsed hundreds of times over a season, including at the factory in the winter, with crews timed to the hundredth of a second.

Where the 20 seconds actually go

Although the tyre change takes two seconds, a pit stop “costs” a driver 20 to 25 seconds compared with a rival who stays out on track. The rest is the pit lane itself: entering, driving its length at the speed limit, and rejoining. That total pit loss is the number strategists work with — and it varies by circuit, which is why some tracks favour one-stop races and others invite two or three. Our strategy guide shows how the undercut exploits that pit loss.

The rules

  • Refuelling is banned and has been since 2010. Cars carry all their race fuel from the start.
  • Pit lane speed limit: 80km/h at most circuits, 60km/h at tighter ones such as Monaco. Speeding brings a fine in practice and a time penalty in the race.
  • Unsafe release: releasing a car into the path of another in the pit lane is a penalty offence, typically five or ten seconds.
  • Loose wheels: a car released with a wheel not properly attached brings a heavy fine for the team and usually a grid penalty for the driver at the next race.
  • Working under the safety car: pit stops are allowed during safety car and virtual safety car periods, and are cheaper because the rest of the field is slowed — a rule that decides races, as our VSC explainer shows.

What goes wrong

Cross-threaded wheel nuts, a gun that fails to fire, a jack that slips, a driver who overshoots the marks by a metre: any of them can turn a two-second stop into a ten-second one. The double-stack — pitting both cars on consecutive laps or, in emergencies, the same lap — is the hardest thing a crew does, because the second car arrives while the first is still being serviced and the crew must reset in seconds. Teams also lose time deliberately when they choose to: a “slow” stop to change a damaged front wing, or a stop timed to release the driver into a gap in traffic rather than the fastest possible moment.

The record

McLaren set the current record of 1.80 seconds at the 2023 Qatar Grand Prix, beating the 1.82 seconds Red Bull managed at the 2019 Brazilian Grand Prix. Sub-two-second stops were once remarkable; now every front-running team can produce them, and the difference between teams is measured in average consistency across a season rather than a single headline number.

Frequently asked questions

How long does an F1 pit stop take?

Around two seconds for the tyre change; the record is 1.80 seconds (McLaren, Qatar 2023). Total time lost including the pit lane is typically 20 to 25 seconds.

How many people are involved?

Around 20 — three per wheel plus jack operators, stabilisers and a crew chief.

Do F1 cars refuel during pit stops?

No. Refuelling has been banned since 2010.

What is the pit lane speed limit?

80km/h at most circuits, 60km/h at tighter venues such as Monaco.
