Twenty-two people, four wheels and about two seconds. Here is the stop as a clock — jack engaged at 0.3s, wheels off at 0.6s, car dropped at 2.1s — plus the sixteen years of refuelling that made it slow, the helium guns that were too expens
What you’ll learn
- The stop begins before the car arrivesExplain how the strategy call, the driver’s accuracy and the FIA’s rules set up the two seconds you actually see.By the time the car turns into the pit lane, the crew has been standing in the box for fifteen seconds, the marks are already painted on the ground, and a rulebook has decided how much of the job a machine is allowed to do.
- Four corners, one movementTrace who does what during the stop, and why the jobs overlap instead of queueing.Twenty-two people, twelve of them on the tyres, run on separate clocks timed to collide in the right order — and every number in the sequence is a fraction of a second.
- How the seconds were taken outFollow the equipment, the rules and the one long detour that produced a sub-two-second stop.The modern stop is not a single invention. It is a refuelling ban, a captive nut, a swivelling jack, a banned gas and a great many arguments about screw threads.
- Practice, and the right to stop everythingExplain why rehearsal, feedback and a deliberate release gate are what make extreme speed repeatable.Crews practise about sixty stops a weekend, including the ones that go wrong, and then give several people the power to stop the car leaving at all.
Questions this course answers
Roughly how long before the car arrives does the pit crew come out into the box?
Formula 1 puts it at ideally 15–20 seconds, which is when the crew get the wheels out and check the prime and spare guns.
Why can a Formula 1 car not be lifted by a powered jack in the pit lane?
The FIA sporting regulations list it among the things competitors may not do, so the jacks are worked by hand.
What are the painted numbers on the ground in a pit box for?
The scale lets the crew measure the driver’s accuracy in practice and feed it back before the race.
How does Mercedes divide the twelve crew members who handle the tyres?
One mechanic works the gun, one pulls the old tyre away and one fits the new one, at each of the four corners.
Why must the rear wheel gunners wait for the car to be completely stationary?
Front gunners can lead onto their wheel as the car arrives; the recessed rear nut means the rear gunners cannot.
Why did pit stop times balloon to eight or twelve seconds after 1994?
With a fuel hose in the car the gunners had time to spare, so the equipment was built for robustness rather than speed.
