United States Grand Prix preview: Antonelli closes on title maths, McLaren brings upgrades, softer tyres set to shape Austin strategy

Austin opens the American swing as Round 18

Formula 1 heads to the Circuit of the Americas this week for the United States Grand Prix, Round 18 of the 2026 season and the start of a triple-header that continues in Mexico and Brazil. Free practice runs on Friday 23 October, followed by practice and qualifying on Saturday 24 October, with the 56-lap grand prix scheduled for Sunday afternoon, 25 October. The 5.513-kilometre circuit covers a race distance of 308.405 km and has hosted the event since 2012, when Lewis Hamilton won the inaugural Austin race for McLaren after a decisive pass on Sebastian Vettel at Turn 12. ¹²⁵

The track remains one of the most physically and technically demanding venues on the calendar. McLaren chief technical officer Rob Marshall describes the series of high-speed corners with tempting kerbs as generating high loads that can unsettle drivers and cause damage, while the enormous 41-metre climb into the blind, windy and bumpy Turn 1 hairpin makes hitting the braking point critical. Pirelli notes in its weekend preview, cited by Formula1.com, that tyre wear rather than graining could prove a key factor, with several tyres reaching very high wear values at last year's event. ¹²

The circuit has also been revised for 2026. GrandPrix247 reports that the section between Turns 9 and 11 has been resurfaced, bumps approaching Turns 12 and 19 have been smoothed, and new blue track-limit lines have been introduced at most corners following numerous lap-time deletions in previous years. ²⁴

Antonelli's first mathematical shot at the title

The championship picture gives Austin added weight. As has been the case since Round 3 in Japan, Kimi Antonelli sits on top of the drivers' standings, but this weekend marks the first in which the Italian has a mathematical chance of sealing his maiden title. Formula1.com details the requirement: Antonelli must win the race with Mercedes teammate George Russell finishing ninth or lower and Ferrari's Lewis Hamilton placing no higher than fifth. Were he to do so, the 20-year-old would become the youngest-ever Formula 1 World Champion. ²

While Antonelli and Mercedes lead the standings, Red Bull has been the form team on track at the last two rounds, with Max Verstappen scoring back-to-back victories in Malaysia and Singapore. Verstappen also holds a formidable record at COTA, having won four of Formula 1's last five visits, and he claimed both pole position and victory there in 2025. The last five Austin polesitters read Verstappen (2025, 2021), Norris (2024), Leclerc (2023) and Sainz (2022). ²

In the midfield, Formula1.com reports Racing Bulls have strengthened their hold on fifth, now holding an advantage of 32 points over sixth-placed Alpine, while Haas arrive in Austin days after confirming rookie Rafael Camara will join the team in 2027. ²

A grid penalty story also looms over the weekend: Formula1.com's coverage flags that Arvid Lindblad, Franco Colapinto and Gabriel Bortoleto are set to take penalties for the United States Grand Prix. The exact grid positions affected were not detailed in the linked summary, so the size of each driver's drop remains to be confirmed in the official classifications. ²

McLaren seeks a reset with modest upgrades

McLaren arrives in Austin hoping to rebound from a difficult stretch. The team's official preview states that the Azerbaijan, Bahrain and Singapore triple-header yielded just 33 points between Lando Norris and Oscar Piastri, leaving McLaren third in the Constructors' Championship with 339 points, 105 adrift of second. Norris sits sixth in the Drivers' Championship with 201 points, 14 off fifth, with Piastri seventh on 138. During the break between races, both drivers returned to the factory to work through data and simulator running. ¹

Chief technical officer Rob Marshall says the team is bringing a modest selection of upgrades aimed at improving some braking reliability and performance issues, along with small floor changes to test. He adds that practice will be important for correlating simulation and tunnel work with the track, and that Austin is probably a better circuit for the MCL40. The preview also notes the 2027 regulation changes are quite modest, so the parts and philosophies on this car remain relevant to next year's direction. ¹

Piastri addressed his form at the FIA's Thursday press conference, saying the last triple-header was more back to where he wanted to be, though not at the level he aspires to. He told reporters the high-speed corners are where the car has been stronger this year and low speeds where it has struggled, and confirmed the car carries a few new bits for the weekend. On the Singapore Sprint contact with Norris, Piastri said he had been happy with how the team handled the situation; the FIA transcript records the questioner, Sky Sports' Craig Slater, expressing the understanding that there were no racing repercussions. ³

Softer tyres and energy management shape the strategic picture

Pirelli has nominated the C2 as hard, C3 as medium and C4 as soft for Austin, moving one step softer than the C1, C2 and C3 allocation used in 2025. In its preview, quoted by Formula1.com, Pirelli explains that the C2 as the hard could favour long stints and a likely one-stop race, but warns the typically high Texan temperatures could increase degradation and open the door to alternative strategies. ²

Williams chief trackside engineer Paul Williams expects a close strategic choice between one-stop and two-stop races, telling GrandPrix247 that teams may favour the softer compounds and potentially avoid the hard tyre altogether. He expects degradation to be driven initially by rear-tyre overheating, then rear wear, then front-left wear, and cautions that the soft compound can be difficult to bring into its operating window before Turn 1 in qualifying, with the strong race performance expected from the soft possibly encouraging teams to preserve fresh sets. ⁴

Under the 2026 regulations, energy deployment and active aerodynamics add a further layer. GrandPrix247 reports Williams identified the Turns 4 to 8 sequence as especially demanding due to its sensitivity to wind and the consequences for energy consumption, with COTA's two active aerodynamic zones on the approaches to Turns 1 and 12 particularly sensitive to deployment. By the team's analysis, race pace is 30 per cent more rewarding than qualifying pace at Austin, predicted to be the easiest circuit for overtaking on the 2026 calendar, while the probability of a full Safety Car is estimated at 30 per cent and a Virtual Safety Car at 50 per cent, above the seasonal average. ⁴

Paddock moves: Raptor makeovers, Cognizant livery and padel

Red Bull has gone all-American for Austin. GPblog reports Max Verstappen and Isack Hadjar will race in specially designed suits inspired by the Ford Raptor, with the garage transformed in Ford Raptor branding and Verstappen's helmet adding a cowboy hat graphic alongside his familiar lion motif. A Castore replica collection goes on sale through the team's store, and the celebrations began with 'The Pull Up' on Wednesday 21 October, an event dedicated to American car culture featuring customised Ford vehicles, a Red Bull show car, live music and Texas barbecue, with Red Bull Austin Race Nights running at Big Texas in East Austin from Thursday through Sunday. ⁶

Aston Martin Aramco is marking the event from several angles. The team's race page confirms a special livery celebrating five years of its partnership with Cognizant, and announces a collaboration with Padeltek launching ahead of the grand prix, including an exclusive I / AM fan event at the new Padel Society venue in Austin on Thursday 22 October. The first collection features three Padeltek padel rackets and three cover bags designed with the team in mind, with pickleball rackets and accessories to follow in 2027. The team also notes technical partner Honda has reached the milestone of 500 Formula One races, and that F1 ACADEMY driver Mathilda Paatz is back in action in Austin. ⁵⁷

On the driver front, Carlos Sainz told the FIA's Thursday press conference that COTA is one of his favourite tracks, though he does not expect a podium this year, describing the upgraded FW48 as good enough to reach Q2 and fight for points only if others err. At Aston Martin, both cars started from the pit lane in Singapore, with the team hoping for better things at COTA, while third driver Jak Crawford is set to drive in FP1 at next weekend's Mexico City Grand Prix. ³⁵
