When Red Bull's pit crew changed all four tyres on Max Verstappen's car in 1.80 seconds at the 2019 Brazilian Grand Prix, it was faster than the human blink reflex. The record still stands. But what makes that number extraordinary is not the time itself — it is the fact that twenty people, each with a single specialized task, executed in perfect synchronization without a single mistake.
In Formula 1, pit stops are one of the few moments where the team can directly gain or lose positions for the driver. A fast stop can complete an undercut. A slow one can trap a car behind a rival for an entire stint. A botched one can end a race.
Each crew member's role
A modern F1 pit stop involves approximately twenty people, each with a precisely defined job:
Front jack: Lifts the front of the car. Must be in position before the car stops and release the moment the new wheels are secure.
Rear jack: Lifts the rear. Same timing demands as the front jack, but must also avoid the exhaust heat.
Wheel gun operators (4): One per wheel. The gun removes the central wheel nut in a fraction of a second. The operator must then guide the new wheel onto the hub.
Wheel removal and fitting (4): One per wheel. Removes the old wheel and positions the new one for the gun operator to secure.
Wheel carriers (4): Bring the new tyres to the car from the garage and take the old ones away. Must arrive at the exact moment the old wheel is removed — too early and they block the gun operator, too late and the stop loses time.
Stabilizers (2): Hold the car steady from the sides during the stop, preventing it from rolling or shifting on the jacks.
Front wing adjusters (2): If a front wing adjustment is needed, these crew members make the change while the tyres are being swapped.
Lollipop/traffic light controller (1): Historically a person with a lollipop flag, now usually an automated traffic light system. The controller signals when the car can safely leave the pit box, checking that all wheels are secure and that no car is approaching in the fast lane.
Every person must execute at exactly the right moment. One person who is half a second slow turns a 2.0-second stop into a 2.5-second stop. In F1, that difference can cost a position.
How a sub-two-second pit stop works
The sequence from car arrival to car departure:
- Approach: The driver hits the pit limiter button and decelerates to the 80 km/h pit lane speed limit. The crew is already in position, crouched and ready.
- Stop: The car stops on its marks. The front and rear jacks engage simultaneously.
- Wheel change: The gun operators remove the central nuts (0.3-0.5 seconds each), the old wheels come off, the new wheels go on, and the nuts are re-tightened. This is the critical phase — all four wheels must be changed in parallel.
- Release: The traffic light system confirms all wheels are secure (the guns have torque sensors that verify nut tightness). The front jack drops, and the car accelerates away.
The entire sequence from stop to release can take under 2.0 seconds. Red Bull's record of 1.80 seconds means the car was stationary for less time than it takes most people to react to a visual stimulus.
How teams train for pit stops
Pit crew members are not dedicated specialists hired only for race weekends. They are mechanics, engineers, and support staff who work for the team year-round and train for pit stops in addition to their regular responsibilities.
Teams practice pit stops dozens of times over a race weekend, often in the early morning before sessions begin. They use reaction-time drills, video analysis, and physical conditioning. Dedicated pit stop coaches study every frame of every stop, looking for milliseconds that can be saved.
The training intensity reflects the stakes. A championship can be lost by a single slow pit stop. Red Bull's pit crew advantage in 2021 was widely credited as a factor in Verstappen's title win — their consistently faster stops gave him track position in crucial moments.
What can go wrong
Pit stop errors fall into several categories:
Wheel nut cross-threading: The nut does not engage properly on the hub thread. The gun operator must reposition and try again, costing several seconds. If the nut appears tight but is not, the wheel can detach on track — a dangerous and potentially race-ending failure.
Jack release failure: If the jack operator drops the car before all wheels are secure, the car leaves the pit box with a loose wheel. This triggers an unsafe release penalty and requires the driver to stop again.
Traffic light malfunction: The automated release system relies on sensors confirming wheel security. If the system incorrectly shows green before a wheel is tight, the car leaves with a dangerous condition. If it shows red after all wheels are secure, time is lost.
Pit crew contact: A crew member touching a car in the fast lane, or a car leaving its pit box into the path of another car, triggers an unsafe release investigation.
Famous pit stop moments that changed races
Hamilton's pit stop error, Monaco 2015: Mercedes called Hamilton in for a stop but the right-rear tyre was not ready. He sat stationary for several seconds while the crew scrambled, losing the lead and eventually finishing third. The error was traced to a miscommunication between the pit wall and the tyre crew.
Ferrari's double-stack failure, Brazil 2019: Ferrari attempted to double-stack both cars in the same pit stop window, but the second car (Vettel) had to wait while Leclerc's stop was completed. The delay cost Vettel positions and contributed to an intra-team dispute.
Red Bull's loose wheel, Germany 2013: Webber's right-rear wheel was not properly secured during a stop. The wheel detached in the pit lane and struck a cameraman, leading to new safety measures including mandatory helmets for pit lane personnel.
Why pit stops shape championships
Over a season, the difference between the fastest and slowest pit crews compounds. Two-tenths of a second per stop, across 20+ races with multiple stops each, adds up to several seconds of cumulative advantage. In a sport where championship margins are sometimes decided by single points, those seconds matter.
Pit stops are also strategic weapons. The undercut — pitting before a rival to use fresh tyre pace in clean air — depends entirely on the crew executing a fast stop. If the stop is slow, the undercut fails, and the driver emerges behind the rival they were trying to pass.
The pit crew may be unsung, but they are not unimportant. Every time a driver gains a position through the pit lane, they owe it to twenty people who practiced that exact moment hundreds of times.
