Understanding F1 Pit Stops
The art and science behind Formula 1's lightning-fast tire changes and race-winning strategies.
What Happens During a Pit Stop?
A modern F1 pit stop involves a team of approximately 20 crew members working in perfect synchronization to change four tires and make any necessary adjustments in under 2.5 seconds.
The Pit Crew Roles
Per Wheel (3 people):
- Gunner - operates the wheel gun
- Wheel Off - removes the old tire
- Wheel On - fits the new tire
Other Positions:
- Front jack operator
- Rear jack operator
- Front wing adjusters (2)
- Steadiers/stabilizers (2)
- Fire extinguisher ready
Pit Stop Strategy
Pit stop timing can make or break a race. Teams use sophisticated simulations to determine optimal pit windows based on tire degradation, track position, and competitor strategies.
The Undercut
Pitting before a competitor to gain track position. The driver on fresh tires posts faster lap times, and when the competitor finally pits, the undercutting driver emerges ahead.
Best used when: Tire degradation is high and there's a large pace advantage on fresh tires.
The Overcut
Staying out longer than a competitor. This works when the track is improving (track evolution) or when maintaining track position is more valuable than fresh tires.
Best used when: Track position is premium (like Monaco) or when you can maintain pace on older tires.
Common Pit Stop Strategies
One-Stop Strategy
Single tire change during the race. Minimizes time lost in pit lane but requires careful tire management.
Two-Stop Strategy
Two tire changes. Allows more aggressive driving and fresh tires, but costs more time overall.
Offset Strategy
Starting on different tires than competitors to create strategic flexibility later in the race.
Pit Stop Records
The fastest pit stop in F1 history was achieved by Red Bull Racing at the 2019 Brazilian Grand Prix, completing a tire change in just 1.82 seconds on Max Verstappen's car.
Modern F1 pit stops are so fast that the car spends more time decelerating into and accelerating out of the pit box than actually stationary for the tire change.
The Pit Lane
Drivers must adhere to strict speed limits in the pit lane - typically 80 km/h (50 mph) during races and 60 km/h during practice. Speeding results in time penalties.
- Pit lane entry: Usually marked by a white line that drivers must stay to the right of
- Pit lane exit: Drivers cannot cross the blend line when rejoining the track
- Unsafe release: Releasing a car into the path of another results in a penalty
Frequently Asked Questions
How fast are F1 pit stops?+
Modern F1 pit stops take approximately 2-3 seconds for a tyre change. The world record is 1.80 seconds, set by Red Bull Racing. A pit stop crew of around 20 mechanics works simultaneously — three per wheel plus jack operators — to change all four tyres as quickly as possible.
What is an undercut in F1?+
An undercut is a strategy where a driver pits before their rival to get fresh tyres. With faster new rubber, the driver can lap quicker and effectively overtake the rival while they are still on old tyres. This works when track position is less important than tyre performance delta.
What is an overcut in F1?+
The overcut is the opposite of an undercut: a driver stays out longer than their rival before pitting. This works when the track is slow for overtaking (like Monaco), when the driver can maintain competitive lap times on older tyres, or when staying out on a circuit with high fuel load disadvantage for the rival.
What happens during an F1 pit stop?+
During a pit stop, a team of ~20 mechanics changes all four tyres simultaneously. Three mechanics per wheel (one to remove the wheel nut, one to take off the tyre, one to fit the new tyre) plus front and rear jack operators, a lollipop/lights operator, and additional mechanics to adjust the front wing or add fuel (in older regulations).
