Key Highlights:
- Circuit of the Americas chairman Bobby Epstein acknowledged that a newly discovered dip at Turn 1 is “not acceptable,” but noted that the rest of the venue’s surface is in strong condition following recent resurfacing efforts.
- Four-time Formula 1 world champion Max Verstappen voiced severe frustration ahead of the United States Grand Prix, claiming track bumps are “out of control” and warning of the physical toll on drivers’ spines.
- Epstein explained that the Turn 1 imperfection is a dip rather than a bump, making an overnight quick-fix impossible on the venue’s notoriously volatile clay foundation.
COTA Boss Addresses Driver Frustrations Over Track Surface
Circuit of the Americas (COTA) chairman Bobby Epstein has responded directly to sharp criticism leveled by Red Bull Racing’s Max Verstappen regarding the condition of the Austin circuit. Speaking to ESPN ahead of the United States Grand Prix, Epstein conceded that an issue at the bottom of the venue’s signature uphill first corner falls short of expectations, confessing that the dip at the bottom of Turn 1 is “not acceptable”.
The controversy escalated after Verstappen, a four-time Formula 1 world champion, utilized his Thursday media duties to openly complain about the uneven circuit conditions. Drawing comparisons to other racing categories, Verstappen expressed deep concern about driver well-being and the circuit’s structural history.
From what I saw in WEC, it was extremely badly bumpy. I’m not really looking forward to that, to be honest, for your spine,
Verstappen told the media on Thursday. I was joking about that in the last race, but it’s not really a joke to be honest. We mentioned this already for years, that it’s actually getting a bit out of control.
“A Dip, Not a Bump”: Why Turn 1 Presents a Unique Challenge
While Epstein acknowledged the flaw leading into the circuit’s steepest sector, he maintained that track officials only became aware of the specific depression days before the Grand Prix weekend. Furthermore, the track boss stood by the extensive maintenance program completed across the rest of the 3.426-mile facility.
We don’t feel good that there’s a bump at the bottom of Turn 1,
Epstein admitted to the outlet. We didn’t know about it until this week. We would have fixed it.
But the other things Max spoke about, all the bumps around the track, we’ve fixed them. The track is in really good shape.
Epstein also pointed to differing feedback from sports car competitors while detailing the engineering hurdle preventing an emergency repair during the race weekend: I talked to some WEC drivers who said there’s no problem. There’s one bump at the beginning of [Turn] 1 that is not acceptable in my mind… It’s a dip, not a bump. If it were a bump, we’d sharpen it out, we’d take care of it tomorrow night, or overnight tonight, and that kind of stuff’s happened before [at other circuits]. But when it’s a dip it’s a lot different, there’s no easy fix.
Underlying Soil Issues and Driver Support
Surface roughness has been an ongoing issue at the Austin venue since its opening. The facility is constructed on expansive clay, a soil type prone to significant shifting, expanding, and shrinking depending on local weather conditions and moisture levels. In an effort to mitigate these recurring shifts, the entire circuit underwent a repaving ahead of the 2024 event. Further localized interventions were carried out ahead of this year’s race, including full repaving between Turns 9 and 11, alongside targeted repairs from Turn 12 through Turn 19.
Despite these engineering projects, Verstappen argued that localized asphalt repairs do not address the root geological causes below the tarmac. Over time, they’ve been grinding a little bit here and there, but you’re putting a plaster on the big problem and that’s just what’s underneath,
he stated.
Verstappen’s concerns are not isolated within the paddock. Other drivers have echoed his sentiments about the harsh ride characteristics at COTA, including reigning champion Lando Norris, highlighting ongoing tensions between modern ground-effect aerodynamic setups and shifting track foundations.
Why This Matters
Modern Formula 1 machinery relies heavily on ground-effect aerodynamics, requiring teams to run cars exceptionally low to the ground and with stiff suspensions to maximize downforce. Consequently, sudden dips or bumps can bottom out the chassis, degrade driver comfort, and risk structural damage to vehicle planks—an issue that has previously triggered post-race disqualifications at COTA. Epstein’s confirmation that the Turn 1 defect cannot be resolved overnight leaves teams with the challenge of managing ride heights and car balance over the course of the United States Grand Prix weekend, while track organizers face renewed scrutiny over long-term civil engineering solutions on the Austin clay.
Frequently Asked Questions
Why can’t COTA immediately repair the Turn 1 issue during the race weekend?
According to circuit chairman Bobby Epstein, the imperfection at Turn 1 is a dip in the asphalt rather than a raised bump. While raised bumps can be ground down overnight, filling and stabilizing a dip requires extensive resurfacing and curing time that cannot be accommodated during an active race weekend schedule.
What causes the recurring bumps at the Circuit of the Americas?
The circuit is built on expansive clay soil, which shifts, swells, and contracts in response to seasonal temperature and moisture fluctuations. This underground movement causes the sub-base beneath the tarmac to buckle over time, creating ongoing undulations despite frequent resurfacing programs.
Did any other Formula 1 drivers support Max Verstappen’s track complaints?
Yes. Reigning champion Lando Norris and other drivers backed Verstappen’s concerns regarding the severity of the track surface and the physical strain imposed by the bumps during high-speed laps.
