Quick Hits

• Title math in Texas. Mercedes arrives at COTA in a one-off blue livery with a very deliberate hope: that Kimi Antonelli clinches the world championship on Sunday. Christian Horner says the 20-year-old has "earned" outright number-one status at Brackley after a dominant 2026.
• RBPT's maiden win keeps reverberating. Red Bull shareholders phoned former team chief Horner to thank him for the engine project after its first Formula 1 victory in Malaysia — with Helmut Marko, despite recent criticism of Horner, calling it "a really, really great achievement."
• McLaren in damage control. Fresh talks followed the Norris–Piastri clash in Singapore, with Norris promising to "make better decisions" — while Piastri admits McLaren likely won't fix its problems before the season ends.
• The FIA has been busy. The WMSC closed a cost-cap staffing loophole, a clarification killed off qualifying-specific wheel designs, and Ben Sulayem wants a V8 rules decision "within months."
• Ferrari swings big in Austin. Its largest upgrade of the season is expected at COTA even as Leclerc warns the problem is the car's "raw performance," not set-up — plus a one-off blueprint-style HP livery.

Championship Picture

Sunday could be coronation day. Motorsport.com reports Mercedes' dramatic new-look car for Austin carries the team's explicit hope that Antonelli wraps up the title this weekend, and r/formula1 is already crunching the permutations. Horner, for his part, argues Antonelli has "earned" the right to be Mercedes' number one. Presumably he'll still be washing his own road car by hand regardless — a habit he revealed ahead of the weekend.

The contrast is Lando Norris. The 2025 champion is putting together one of the worst title defences the championship has ever seen and risks an unwanted record. McLaren held fresh talks after his Singapore clash with Piastri — which drew the ire of team management — and Piastri's own verdict is bleak: with six races remaining, he doesn't expect a fix before the season closes.

Zoom out and the numbers show Mercedes has lost its early-2026 supremacy — F1.com sees the reshuffled order setting up a thrilling 2027 battle. One operational wrinkle: Mercedes revealed some of its Singapore pit crew were doing their first live stops in 15 years as the first of three planned triple-headers bit hard.

Technical & FIA

• Cost cap plugged: The WMSC approved regulations preventing teams' non-F1 staff from working on F1 projects — Jon Noble explains why the FIA is now fussy about where people work, "canteens, car parks and gyms" included.
• Wheel war averted: Teams had begun running different wheel designs in qualifying versus the race to control tyre temperatures; the FIA nipped the arms race in the bud before it became a spending contest.
• Floor stays banned for 2027: Mark Hughes details how a floor-stay exemption let Red Bull and Audi run sharper sidepod undercuts this year — and how the FIA is closing it.
• V8 clock ticking: Ben Sulayem wants the 2030 engine decision within months, warning: "there will not be a V8, maybe V16 if they don't take a V8."
• Courtroom drama: Former fuel flow meter supplier Sentronics is suing its replacement in Texas, claiming the sensors now fitted to every car infringe its patents.
• Car trouble: Pierre Waché links Verstappen's RB22 degradation to aero wear, mechanical grip and suspension — three connected problems, per the technical director.
• Upgrade calls: Mercedes will decide its Austin package after splitting its cars in Singapore, where Antonelli kept the update.

Driver News

• Horner week continues: Fresh from the RBPT win callbacks — shareholders thanking him for the engine project, with Marko crediting the decision because "Mercedes wouldn't have given us an engine" — his memoir Drive drops revelations: a claimed 2012 "secret meeting" with Hamilton ("I thought he seemed strangely vulnerable for a former world champion" — Motorsport.com, PlanetF1), new details on 2021 Abu Dhabi, and a jab at Steiner: "I don't think he ever achieved a podium in Formula 1!"
• Silly season: James Hinchcliffe makes the case that Lawson deserves to keep his Racing Bulls seat, while a pundit calls the drag "nightmare fuel" for a driver.
• Hadjar has gone off sprint weekends after his Singapore ordeal.
• Perez approaches his 300th start with Cadillac launching an 11-unit, $222,500 Escalade-V in his honour — wait, make that Checo's special edition, numbered for his race number.
• Futures: Ferrari junior Camara will race in F1 with myopia and astigmatism, relying on contact lenses when he joins Haas in 2027; Fenestraz says Ferrari has promised him a 2027 test. Formula E boss Jeff Dodds has re-invited Verstappen to try the Gen4 car.

Race Weekend Preview

COTA, six rounds left, a championship on the line. Your prep list: Motorsport.com's five things to watch, PlanetF1's predictions — "Hamilton magic or misery, Verstappen glory and an apology to Antonelli" — plus F1.com's pole contenders and early Bet Builder.

Ferrari's weekend to swing: the largest upgrade of the year is expected amid Leclerc's "raw performance" admission, with a blueprint-style HP livery unveiled. Hamilton also has a familiar face nearby: his former Mercedes engineer is now "Chassis Vehicle System Specialist" at Maranello.

Austin flavor: Antonelli and Russell trying on boots at Tecovas, Glenfiddich premiering its Aston Martin partnership in San Antonio — and history humming: Räikkönen became Ferrari's most recent champion on this day in 2007, taking his final win at COTA exactly 11 years later, while Alonso's second title turns 20 today.

Calendar watch: Hockenheim confirms talks with F1 despite "virtually zero" public funding — still "largely theoretical." And if you've got $9,950 spare, there's now an F1-branded Leica.
