Charles Leclerc’s best chance to gain time with an undercut at Austin may arrive before anyone sees a pass. The Ferrari dives into the pit lane, Leclerc hits his marks, and four fresh tires go on. Seconds later, he fires back toward Turn 1 with open asphalt ahead and a rival still circulating on worn rubber. That is where the move lives.
At the Circuit of The Americas, a successful undercut demands more than a quick stop. Ferrari must recognize fading tires early, find a clean rejoin window, and give Leclerc enough grip to attack immediately. One mistimed lap can erase the whole advantage.
The stakes feel sharper in 2026. Leclerc sits fourth in the championship with 138 points, while teammate Lewis Hamilton has 169. Their internal battle remains just as tight on track: Leclerc leads their qualifying head-to-head 6-5, while Hamilton owns the same 6-5 advantage on Sundays.
That margin leaves little room for wasted opportunities. If Ferrari cannot always beat its rivals with raw pace, the pit wall has to manufacture positions another way. Austin gives it that chance.
Austin Rewards the Team Willing to Move First
COTA can trap a fast car behind a slower one for longer than expected. The rapid sweepers from Turns 3 through 6 punish anyone following closely because dirty air takes load away from the front tires. The driver behind starts fighting understeer instead of attacking, and by the time the circuit opens toward the back straight, those tires may already have taken a beating.
Passing remains possible, particularly under braking for Turn 12. Still, a clean overtake can require several laps of preparation. The undercut offers another route.
Ferrari already knows how effective that route can be in Texas. During the 2024 United States Grand Prix, Carlos Sainz jumped Max Verstappen through the pit sequence and secured second place behind Leclerc. Rather than asking Sainz to defeat the Red Bull wheel-to-wheel, Ferrari used fresh rubber and clear track to do the work.
Leclerc found a similar value one year later. During the 2025 race, Lando Norris passed him for second on Lap 21 before Ferrari brought Leclerc in two laps later. Once Norris made his own stop, the Ferrari had regained the position through the undercut.
Two laps changed the order, and that history gives Ferrari more than a theoretical strategy model. The team has watched COTA reward an early move in consecutive seasons.
Ferrari Cannot Pick the Pit Lap Before the Race
The temptation will be to identify a target window before Sunday: perhaps Lap 18, maybe Lap 20, or somewhere in the low 20s if degradation develops as expected.
Ferrari should resist that thinking.
Leclerc reached his first stop in the low 20s during the 2025 race, but the 2026 strategy cannot revolve around copying an old lap number. Tire behavior, fuel loads, track temperature, and traffic will reshape the calculation.
Fred Vasseur highlighted the scale of that sensitivity after Ferrari’s difficult Friday at Austin in 2025. He explained that missing the correct tire operating window could cost roughly five or six tenths of a second per lap in performance. Half a second changes everything when two cars are separated by only a few seconds on the road.
If the car ahead begins bleeding that amount while Leclerc can switch onto fresh rubber, Ferrari may need only a couple of strong sectors to create the margin. Wait another lap, however, and the rival gets the chance to cover.
The tires should trigger the decision. Leclerc’s lap time gives engineers one signal, while his steering inputs provide another. A growing correction through the esses, poor rotation into the slower corners, or traction loss onto the back straight can reveal that the current stint has reached its useful limit.
Ferrari may not need absolute certainty at that point. It simply needs to recognize the decline before the pit wall ahead does.
The 2026 Tire Choice Still Matters
One major variable remains unresolved: Pirelli has not yet announced its compound allocation for the 2026 United States Grand Prix. That prevents Ferrari from building the final strategy picture months in advance.
The 2025 race also showed why assuming a conventional allocation would be dangerous. Pirelli brought the C1 hard, C3 medium, and C4 soft, deliberately skipping the C2. The unusual selection increased the performance difference between available compounds and widened the strategic possibilities.
This October could look different, but the basic equation will remain the same. Ferrari must identify the crossover between protecting tire life and gaining immediate lap time.
A fresh set only creates an undercut if Leclerc can extract enough performance before his rival pits. Stop too early, and he may pay for that decision late in the stint; leave him out too long, and the opening disappears.
That narrow strip between patience and aggression is where Ferrari has to operate.
Leclerc’s Out-Lap Must Feel Like Qualifying
The pit wall can create the opportunity. Leclerc has to cash it in.
His first lap after the stop cannot be a gentle warm-up exercise. Fresh tires mean little if he spends half the lap bringing them to life while the rival ahead continues at full speed. Instead, Leclerc needs commitment almost immediately.
Through the climb to Turn 1, he can load the front axle under braking and begin generating temperature. The fast opening then asks for precision rather than wild aggression. Sliding the tire across the surface may create heat, but it also damages the grip he needs later in the stint.
A stronger opportunity arrives under the heavy braking for Turn 12. From there, traction through the final sector can determine whether the undercut gains three-tenths of them.
One lock-up can ruin the calculation, so Leclerc has to drive close to qualifying intensity without treating the lap like qualifying. He still needs those tires after the stopwatch has delivered the position.
That balance suits his skill set. Few drivers attack a low-grip lap with more confidence, and his 6-5 qualifying edge over Hamilton this season reinforces the point. Sunday, though, has demanded more. Hamilton leads their race head-to-head by the same margin and carries the championship advantage.
Strategic execution can help Leclerc close that gap.
Traffic Is the Part Ferrari Cannot Control
The fastest out-lap in the world becomes useless behind two cars fighting for 12th. Ferrari therefore has to map the road before Leclerc reaches pit entry, knowing where he will rejoin, how quickly the traffic ahead is moving, and whether those cars will interfere with his strongest sectors.
Catching a Haas or Alpine side byside-by-sideurn 1 could immediately cost several tenths. Meeting the same fight through the esses may hurt even more because Leclerc would lose clean air while trying to bring his fresh tires into their operating window.
Clear track therefore becomes part of the pit-stop calculation rather than a bonus.
A rival can also wreck the plan without appearing anywhere near Leclerc. An unexpected stop changes the rejoin order, while a driver stretching a stint can occupy space Ferrari expected to use. A sudden yellow flag can turn an aggressive call into a costly one within seconds.
That uncertainty explains why the best strategy teams think several laps ahead. Ferrari cannot simply ask where Leclerc will rejoin. The better question is where everyone else will be when he gets there.
Staying Close Creates Pressure Before the Stop
Leclerc can help Ferrari long before the mechanics leave the garage. He needs to remain close enough to make the undercut believable without destroying his own tires in the process.
If the gap stretches to four or five seconds, the driver ahead gains breathing room. That team can extend the stint, react later, and protect track position without panic. A smaller gap changes the conversation because every Ferrari lap suddenly carries a threat.
The rival then faces an uncomfortable choice: pit first and surrender useful tire life, or stay out and risk losing the position.
Leclerc does not need to throw the car into every braking zone to create that pressure. Controlled pace may work better. Protect the tires, remain inside the strategic window, then attack when Ferrari makes the call.
In Austin, patience can create aggression.
Ferrari Gets More Time to Solve the Puzzle in 2026
The 2026 United States Grand Prix runs from October 23 to 25, and this year’s event returns to a conventional weekend format with three practice sessions before qualifying. Ferrari should welcome that extra mileage.
Long runs can reveal how quickly each compound fades and how the car behaves as the fuel burns away. Engineers can also study warm-up, track evolution, and the likely time loss through the pit lane, building a clearer picture of where Leclerc might rejoin under different scenarios.
None of that guarantees the right decision on Sunday because race conditions can destroy a carefully prepared strategy within minutes. A hotter track may accelerate degradation, an early safety car can tear apart the planned stint lengths, and traffic can appear where simulations predicted open asphalt.
Ferrari therefore needs preparation without becoming trapped by it. The numbers should guide the call, not make it automatic.
One Perfect Lap Can Steal the Position
For Leclerc, the undercut only works if Ferrari treats the move as a chain rather than a single pit stop.
First, he has to stay within striking distance. The pit wall must then spot the tire drop before the rival does, while a clean piece of track needs to appear behind him. His mechanics cannot surrender precious tenths during the stop.
Then Leclerc has to attack.
Austin has already shown Ferrari what that sequence can produce. Sainz used it to beat Verstappen to second place in 2024, while Leclerc used it to regain track position over Norris during the 2025 race. Those examples matter because neither position required a desperate lunge into a braking zone.
The next version may look almost uneventful.
A rival crosses the timing line ahead as Leclerc disappears into the pit lane. Twenty seconds dissolve in noise, wheel guns, and motion. The Ferrari then emerges onto an empty stretch of COTA, fresh tires digging into the asphalt while the stopwatch begins cutting into the gap.
No dive into Turn 1. No last-second attack at Turn 12.
Just one hard out-lap, one sharp strategy call, and the timing screen quietly flipping the order. That may be the cleanest pass Leclerc makes all afternoon.
