Pit stop timing in Formula 1 is often decided by two competing strategic concepts known as the undercut and the overcut, both aimed at gaining track position without actually passing on track.
What the Undercut Is
An undercut happens when a driver pits before a rival, fits fresh tires, and uses the extra grip to set faster lap times while the rival is still out on older, worn rubber. By the time the rival pits a lap or two later, the undercutting driver may already have built enough of a gap to emerge ahead.
What the Overcut Is
The overcut is the opposite approach: staying out longer than a rival, banking lap time on a track that’s temporarily clear of pit stop traffic, and hoping that advantage outweighs the tire wear penalty of running longer than planned.
Track Position vs. Tire Life
Both strategies exist because track position is often more valuable than tire freshness in modern F1, since passing on track can be extremely difficult at many circuits. Teams model these tradeoffs extensively before a race, similar to how championship battles like the one detailed in Max vs 100 often come down to strategic calls as much as outright pace.
Why It Doesn’t Always Work
Undercuts and overcuts aren’t guaranteed to succeed. Traffic, safety cars, or a driver simply not producing the expected pace on new tires can turn a promising strategic gamble into a costly mistake that drops a car several positions instead of gaining them.
Watching for It During a Race
Once you know to look for it, you’ll notice broadcasters and teams constantly discussing pit windows in exactly these terms, and understanding the undercut and overcut makes it much easier to follow why a driver pitted when they did, rather than a lap earlier or later.
