During his final pit stop, Lewis Hamilton (Mercedes-AMG Petronas F1 Team) was told, “It will all comes down to the final three laps" by team principle Toto Wolff.
And how right he was.
With three laps to go, Hamilton trailed race leader Max Verstappen (Red Bull Racing Honda) by less than 2 seconds. Hamilton had the newer tires and the DRS advantage, but Verstappen held on due in part to precision driving and the fortunate ability to use the DRS himself as a result of a lapped driver in front of him on the final lap.

With just six races left in the 2021 Formula 1 season, the United States Grand Prix was a critical race in the scuffle between reigning champ Hamilton and Verstappen.
Some F1 tracks almost guarantee a win for the pole-sitter, as they may not have enough straightaways (and/or DRS zones) or passable corners. But COTA is different, as the 20-turn, counterclockwise circuit features undulating surfaces that can rapidly shift weight distribution in the racecar, or damage it, and a 133 foot climb to the left turn on corner one from the main straight. COTA’s long main straight allows for high speed DRS passes, and enough corners for wily racers like Hamilton and Verstappen to be in contention for the win no matter the starting position.Race start was a superb reflex show by Hamilton, who got the jump on Verstappen and bolted into the lead from P2 to P1.
It was game on from there.
Verstappen then radioed in that his rear was sliding through turns. That, combined with turbulent and dirty air from Hamilton, the task of regaining the lead would be more difficult for the charging bull.Strategy and pit lane timing proved to be the winner for Red Bull Racing Honda as twice they used the undercut strategy, to force Hamilton back in between Verstappen and Perez.
Undercutting involves a driver making a pit stop a few laps earlier than the car ahead of you.
This ensures the driver has a fresher set of tires, which can help him overtake the worn-out tires of his opponent. The lap times are quicker, and once he gets within 1 second of the opponent ahead, the DRS (Drag Reduction System) can help in overtaking.
Once this happens, one could naturally expect the opponent to go for a pit-stop of his own. The opponent would go for a fresher set of tires too, but if the gap is big enough by then, he could end up behind the undercutting driver. It’s a very tricky maneuver, but if done well, can yield the driver the crucial track positions.
