Lawson’s RB teammate Yuki Tsunoda was the clear winner among Red Bull’s four cars, putting together a lap of 1m 17.787s to be third in the day’s second practice.
World champion Max Verstappen managed 1m 18.839s for fourth place in practice one but was forced to sit out of the second session after an issue with his car.
Mercedes’ George Russell topped practice one after clocking 1m 17.998s, while Ferrari’s Carlos Sainz was quickest in practice two with 1m 17.699s.
While admittedly only in practice, where teams look for more than just lap times, Lawson getting the better of Perez is significant in the race for a seat in 2025.
Entering the Mexican Grand Prix weekend, Perez is 204 points behind Verstappen in the drivers’ championship. Meanwhile, Red Bull’s lead in the constructors championship has been reeled in by McLaren, who hold a 40-point advantage at the top.
Despite Perez re-signing with Red Bull earlier this year on a contract for 2025 with a further option for 2026, the Mexican is by no means safe, especially if he proves to be the difference to McLaren at the top of the constructors’ standings.
It is widely understood Lawson’s initial confirmation of six races in 2024 is an audition to succeed Perez in the Red Bull car next year, otherwise, he will stay with RB to gain experience until a seat in the senior team becomes available.
While Perez finished seventh to Lawson’s ninth in Texas, he did so in a car that has scored 508 more points than the RB over the course of the season.
It is also understood that despite scoring the majority of RB’s points this season, Tsunoda is unlikely to be promoted into Red Bull’s senior ranks.
Tsunoda’s place in the team is widely tied to his links to Honda, Red Bull’s engine supplier across its two teams.
However, Honda will leave Red Bull after 2025 to join Aston Martin, which could see Tsunoda follow if a seat opens up in the team that is bankrolled by Canadian billionaire Lawrence Stroll.
Drivers will complete a third practice session and qualifying on Sunday, before the Grand Prix on Monday (NZ time).
