Red Bull traces Verstappen’s Interlagos puncture to carbon — with Hamilton–Colapinto clash in the frame
Max Verstappen turned a pit-lane start and an early puncture into a podium at Interlagos, and now we know why the RB21’s charge was almost derailed: a shard of carbon. Red Bull believes debris from the chaotic opening laps — and specifically the collisions involving Lewis Hamilton and Franco Colapinto, or Lance Stroll and Gabriel Bortoleto — likely cut Verstappen’s tyre. In Helmut Marko’s estimation, there’s a “50 percent” chance Hamilton’s clash with the Alpine was the culprit.
It was that sort of Brazilian Grand Prix. Verstappen’s weekend started with something he’d never experienced on pure pace in Formula 1 — a Q1 elimination — which triggered a wholesale reset. Red Bull bolted in a fresh Honda engine, tweaked the set-up aggressively and accepted a pit-lane start. What followed was Verstappen at his most ruthless, slicing through traffic to third and, if not for a superb late stand from Mercedes’ Kimi Antonelli, perhaps nicking second.
Marko lifted the lid on the turnaround and the puncture in his post-race debrief. The team, he said, ran two different floors across the weekend and fell out of the RB21’s notoriously narrow operating window in qualifying — the sort of car that can be tipped off balance by half a millimetre of ride height or a few degrees of track temp. On Sunday, they found it again.
“Thankfully, we managed to sort it out for the race,” Marko said, praising a “resurgence” after Red Bull’s bruising mid-season lull. Verstappen’s race pace on the hards was strong enough to support a bold long first stint — right up until the tyre started bleeding air.
The opening exchanges were messy. Bortoleto nosed the wall at Turn 10. On the run to the line, Hamilton tagged the back of Colapinto’s Alpine, sacrificing his front wing and inflicting floor damage that eventually parked the Ferrari-bound seven-time champion. Somewhere in there, Verstappen picked up the fateful sliver.
“Max got a puncture from a piece of carbon fibre from colliding opponents,” Marko explained, pointing to either Stroll versus Bortoleto or Colapinto versus Hamilton. A sharp-eyed Red Bull data engineer flagged the slow leak in time to force an early stop, and a well-timed Virtual Safety Car blunted the damage. The original plan — stay out long on hards while the soft- and medium-runners blinked — was shelved, but Verstappen still made it sing.
The broader headline for Red Bull might be even more important: they’ve got a clearer read on what makes the RB21 happy. The team now knows which underbody to carry forward and which wing level keeps the tyres in step, according to Marko. Yuki Tsunoda’s car stayed closer to the pre-race baseline to help triangulate the set-up gains — an old-school, two-pronged approach that finally paid off.
It needed to. Interlagos was another weekend where the championship picture sharpened at Verstappen’s expense. Lando Norris swept the Sprint and the Grand Prix to stretch his lead at the top, with Verstappen third in the table and only three rounds left to play. If the title does get away from them, Marko concedes the damage was done in the post-Imola slump — a flat patch that cost Red Bull a stack of points and plenty of momentum at exactly the wrong moment.
There was at least some comfort in the Constructors’ standings. With neither Ferrari scoring in São Paulo, Red Bull climbed to third and lopped a chunk from the gap to second-place Mercedes, though the Silver Arrows still hold the advantage heading into the decisive triple-header in Las Vegas, Qatar and Abu Dhabi.
That schedule will be a brutal stress test for a car with such a sensitive sweet spot. Interlagos suggests Red Bull has finally mapped the path back to it, but the margins are wafer-thin. The RB21 doesn’t give you much; when it does, Verstappen can still wring out the kind of Sunday that turns a slow puncture and a pit-lane start into a trophy.
Two takeaways as the season hits the home stretch:
– The fix feels real. A defined floor choice and wing level, corroborated by Tsunoda’s comparison run, should make Red Bull less reactive weekend to weekend.
– The clock is ticking. Norris has the scoreboard pressure and the form. Verstappen needs everything to land — set-up, starts, strategy — and maybe a little chaos ahead to keep the fight alive.
Brazil gave us both versions of 2025 in one afternoon: the small misstep that’s bitten Red Bull all year, and the ruthless execution that’s kept Verstappen in the argument anyway. If they bottle the latter for the final three, this title race isn’t dead yet. If not, Interlagos might be remembered as the day the debris told the story.
