55 degrees in the asphalt – the race where strategy could buy nothing
Pirelli said two stops, and two stops it was. Russell won from pole on the simplest strategy in the field, Verstappen tried an undercut and Mercedes covered. The simulator says no alternative would have beaten Russell – in the Spielberg heat it was tyre management, not pit calls, that decided the order at the front. Except for Leclerc. And then there is Antonelli's lap 24, the one point in the race where we have to admit the model isn't good enough.
The Red Bull Ring does not wear tyres mechanically; the problem is thermal, above all the rears through the acceleration zones. Pirelli brought the softest compounds – C3 as hard, C4 as medium, C5 as soft – and then got a Sunday of around 36 degrees in the air and 55 in the asphalt, per F1.com. After Saturday Pirelli said two stops were most competitive, M → H → H or M → H → M depending on which sets the teams had left, with an aggressive three-stop as the alternative – roughly two seconds slower with traffic counted in, potentially faster in clean air, per Pirelli.
They were right. Degradation was the season's highest: hard 0.074 s/lap, medium 0.082, soft 0.064 – and one stop was out of the question. Sixteen drivers ran two stops, three ran three. And almost the whole field made the same starting choice: 20 of 22 on mediums, only Bortoleto and Sainz on softs. The strategy fight at the front therefore came down to one thing: when the first stop would come.
Russell led from pole. Verstappen had worked his way up to third and became a threat. On lap 18 Red Bull went first – Verstappen in for hards, an undercut attempt. Mercedes reacted the next lap: Russell in, and out 2.6 seconds ahead. The undercut was worth about six seconds against a lead of nearly nine; Mercedes had margin, but did not try to be cleverer than necessary. Max stops – cover Max. Russell had built the gap in the first stint so the team could choose its stop rather than be forced into it, and Mercedes themselves described that as part of the win, per F1.com.
That, in practice, was the race. Russell ran M → H → H with stops on laps 19 and 43, the "boring" strategy, and all three on the podium used hards for the final two stints, per Pirelli. Verstappen came back at him in the final stint to 1.6 seconds – but no closer. Click a scenario to load it in Simulate below.
| Scenario | Actual | Simulated | Race time | Comment |
|---|---|---|---|---|
| RUS doesn't cover Verstappen, stops under the VSC | P1 | P1 | −10.0 s | Mercedes had margin – but could not know that on lap 19. |
| VER undercut three laps earlier | P2 | P2 | +4.2 s | No timing beat Russell. |
| VER waits for the VSC | P2 | P2 | −0.2 s | Same. |
| ANT stops under the VSC instead of the lap before | P3 | P1–P3 | uncertain | The one scenario in our series the model cannot settle – see below. |
| LEC two stops M → H → H | P8 | P6 | −14.7 s | The third stop cost two places. |
| HAM two stops M → H → H | P5 | P6 | +10.5 s | For Hamilton three stops was right. |
| NOR stops with Piastri | P7 | P6 | +3.8 s | The overcut attempt gave nothing. |
Antonelli had an awkward opening and Mercedes extended his first stint to lap 24 to build a tyre offset. The same lap Sainz stopped on the start-finish straight; Antonelli pitted, and shortly afterwards the VSC came. Pirelli noted afterwards that he stopped slightly too early and missed the discount, per Pirelli.
The data proves Pirelli partly right. Hamilton's lap-25 stop, under the VSC, was cheaper than Antonelli's on lap 24. But by how much, we do not know. This neutralisation was short and ended mid-lap, and the pit loss under it cannot be measured to better than a couple of seconds. Across that range Antonelli finishes anywhere from P1 to P3 in the simulation. So we can say the stop came one lap too early, and that it cost something – but not how much, and not whether it cost a position. Antonelli finished 0.375 seconds behind Verstappen; the margin is smaller than our uncertainty.
What is certain is that the call was reasonable when it was made. On lap 24 Sainz was stationary on the start-finish straight with no VSC declared. Mercedes took the stop they could see, not the one that came a lap later.
What worked was the idea: 27 laps' fresher hards at the end, and Antonelli closed on Verstappen to 0.375 seconds at the flag. Mercedes said afterwards they almost wished for one more lap, per F1.com.
Hamilton took Leclerc at once and ran second. Then the heat got into Ferrari's tyres: Hamilton's first medium stint lost 0.152 s/lap, the worst slope in the field, and Ferrari stopped early – Hamilton on lap 12, Leclerc on lap 13. An early first stop moves the whole strategy forward, and both ended up on three stops, with Gasly the only others in the field. Hamilton said afterwards that Ferrari had reckoned before the start that three stops could be needed, per F1.com.
For Hamilton it was right: with his degradation a two-stop would have been nine seconds slower and a place worse. His P5 was what the car had. For Leclerc it was wrong: his second hard stint had a slope of 0.026 – the tyres were holding – and a third stop for softs on lap 59 cost 16 seconds and two places. P8 instead of P6. It is the only strategy decision in the race that moved a place at the front.
Pirelli concluded afterwards that the undercut worked but the overcut did not, per Pirelli. McLaren had it confirmed: Piastri in on lap 19, Norris asked to extend, Norris replied that the tyres had little left and stopped two laps later. At 55 degrees there was no life left in the medium to be gained by staying out.
| Driver/team | Idea | Outcome |
|---|---|---|
| Russell/Mercedes | M → H → H, cover Verstappen | P1 – right, and at no cost |
| Verstappen/Red Bull | Early undercut | P2 – right attempt, no timing was enough |
| Antonelli/Mercedes | Extended stint, tyre offset | P3 – right idea, one lap too early; how costly cannot be computed |
| Hamilton/Ferrari | Three stops | P5 – right for the degradation the car had |
| Leclerc/Ferrari | Three stops | P8 – the third stop cost two places |
| Norris/McLaren | Overcut attempt | P7 – gave nothing |
| Pirelli | Two stops | Right |
Austria is the counterpoint to Hungary. There Norris won by staying out in clean air; here there was no air left in the tyre to stay out on. The same move – the overcut – was the best of the race at the Hungaroring and Pirelli's declared loser at Spielberg. The difference was 55 degrees in the asphalt and a medium losing 0.08 s/lap. It is the most useful lesson so far in this review of 2026: the best strategy is not a tyre sequence, it is reading what the circuit, the temperature, the traffic and track position make valuable that day. And sometimes, as here, they make nothing valuable at all – then the driver who wears the tyres least wins.
How we did it: lap data from FastF1 (F1 Live Timing). Degradation = within-stint slope on green laps, fuel-corrected at 0.035 s/lap. Pit loss under VSC measured from the race's stops. The simulator runs everyone else on their actual lap times and models the changed driver on his own pace per compound from the race.
