Everything but a Thousandth Came From the Middle Sector

The Data Remembers

Verstappen won the first sector of the lap. Antonelli won the last one by a thousandth more. Whatever separated them on the timing screen, all of it bar 0.001 was made between Turn 7 and Turn 12.

Verstappen Took Sector 1. Antonelli Took Sector 3 by a Thousandth More.

One thousandth. That is what the first and third sectors of the two fastest laps in Austin add up to once they are set against each other. Max Verstappen took the opening sector by 0.056. Kimi Antonelli took the closing one by 0.057. Two sectors, more than 56 seconds of driving between them, and they very nearly erase each other.

Which leaves the middle. Antonelli’s 1:34.035 beat Verstappen’s 1:34.214 by 0.179, and 0.178 of it was made between the first timing line and the second. Both laps came on the first Q3 run. Neither driver improved on the second, and Verstappen’s second attempt was struck off for track limits. Behind them the order was crowded. Hadjar was third, 0.036 behind Verstappen, and five drivers finished inside 0.276 of pole.

Net 0.179 to Antonelli. S1 and S3 together: 0.001.

It was Antonelli’s 7th pole of 2026, on a weekend when he arrived 102 points clear and can leave as champion. The pole tells you who won. The split tells you where to look. When two sectors cancel, the third is not the largest share of the gap. It is the gap. The middle sector is about 40 per cent of the lap on the clock. It carried more than 99 per cent of the margin.

Two sectors of driving, and the net difference was 0.001. The pole lived in the one between them.

Sheet 02

The Red Bull Was Geared Shorter, Gear for Gear

Before the laps can be compared, the cars have to be. Divide engine speed by road speed at full throttle, one gear at a time, and the gearing falls out of the trace. The Red Bull turns more revolutions for every km/h than the Mercedes in each gear from fourth to eighth. In fourth the margin is 8.0 per cent, in fifth 7.1, in sixth 2.8, in seventh 3.9 and in eighth 3.8. Each of those figures rests on at least 14 clean samples per car. The three lowest gears are left out, with too few clean samples to judge.

Revs per km/h at full throttle · Red Bull over Mercedes
4th +8.0% (n 14 v 20) · 5th +7.1% (20 v 19) · 6th +2.8% (31 v 29)
7th +3.9% (58 v 64) · 8th +3.8% (39 v 30)
Hadjar’s Red Bull within 1% of Verstappen’s in every one.

Isack Hadjar’s car reads within 1 per cent of Verstappen’s in every one of those gears. This is the specification of the car, not a habit of the driver. What each driver does on top of it is less fixed. Hadjar takes first gear for Turn 15 and second for Turn 20, one below Verstappen at both. The ratios are shared. The choices made with them are not entirely.

Shorter gears mean a higher gear for the same corner. There are 9 braked corners on the lap. At 6 of them, Turns 1, 8 and 9, 11, 13 and 14, 15 and 20, Verstappen takes the apex one gear above Antonelli. Where the Mercedes drops to first, the Red Bull holds second. At Turns 7, 12 and 19 the two match. On the approach to Turn 1 the shorter ratios show at speed. Verstappen is in eighth 196 metres after the line. Antonelli stays in seventh until he brakes.

None of it shows in the fastest part of the lap. Antonelli peaks at 341 km/h before Turn 12, Verstappen at 339, and the speed trap read 328 and 326. Above 290 km/h a car in normal mode is permitted less electrical power with every km/h it adds. At 339 the figure has fallen to about 105 kW. Both cars ran the last part of the long straight inside that tapering band, where the regulations narrow the room either car had to differ.

The ratios describe a choice, not a verdict. A trace can say which gear each car used and where. It cannot say which choice was right, and the lap will argue both ways before it is finished.

At 6 of 9 braked corners the Red Bull sat one gear higher. The top speeds finished 2 km/h apart.

Antonelli’s Sector 2 Edges All Came From Turn 9 Onward

The middle sector runs longest on the clock and is the hardest to read. It opens as the Turn 6 stop finishes, takes in the final fast change of direction and the paired stops of Turns 8 and 9, and then the Turn 11 hairpin. After that comes the long straight and the biggest stop of the lap at Turn 12. No valid Q3 lap went through the middle sector quicker than Antonelli’s 37.297. Verstappen’s 37.475 was slower than Hamilton’s, Russell’s, Hadjar’s and Leclerc’s, all of whom qualified behind him.

It does not open badly for the Red Bull. Verstappen carries 196 km/h through Turn 7 to Antonelli’s 194, and has the throttle flat 52 metres past the apex. Antonelli never gets beyond 71 per cent before the next stop. The Red Bull arrives at Turn 8 3 km/h quicker, 203 to 200. For the first few hundred metres of the sector the faster car is the one that will lose it.

Then the order flips, and it does not flip back. At the bottom of Turn 9 Antonelli carries 147 km/h in third gear. Verstappen carries 145 in fourth. Both are flat again a little over 100 metres later. On the run through Turn 10 the Mercedes peaks at 284, the Red Bull at 282.

Turn 11 is where the difference grows large enough to see without squinting. The minimum is a draw, 75 km/h for Antonelli in first gear and 76 for Verstappen in second. What separates them is what follows. Antonelli has the throttle flat 62 metres beyond his own apex. Verstappen needs 72. Take each car 100 metres past its own apex and the Mercedes is doing 187 km/h, the Red Bull 182. Not until 250 metres are they level, and by then both are approaching 270.

Turn 11 · ANT v VER
Minimum 75 v 76 km/h · first gear v second
Apex to full throttle 62 v 72 m
100 m past each car’s own apex 187 v 182 km/h

The straight that follows does not close the account. Antonelli reaches 341 km/h, Verstappen 339. Past the peak, with both throttles still flat, the Mercedes keeps 2 to 4 km/h more over the next 250 metres. By the time both cars reach the Turn 12 braking zone they are level again, at 325.

Turn 12 hands nothing back. The minimums are 89 and 88. Verstappen is flat 38 metres after his apex to Antonelli’s 49, and 100 metres on the two read 185 and 184. The hardest braking event of the lap comes out level.

So the trace sorts the sector into two halves. Every place Verstappen was measurably quicker sits before Turn 9, or at Turn 12, where it bought nothing lasting. Every place Antonelli was quicker by more than a single km/h sits between the bottom of Turn 9 and the Turn 12 braking zone. The 0.178 is a timing figure. The trace can place it along that stretch and no finer, and it does not need to. One car left the hairpin sooner and kept a little more of the straight. The other had been quicker into the sector and had nothing to show for it at the far end.

Before Turn 9 the Red Bull was quicker. From Turn 9 until the long straight ran out, it never was again.

Hadjar’s Car Matched Verstappen’s Gearing and Beat His Sector 2 by 0.084

If the Turn 11 exit were the whole story, it would be a story about the car. The other Red Bull says otherwise, and also says yes.

Hadjar qualified third, 0.036 behind his teammate. His middle sector was 37.391, 0.084 quicker than Verstappen’s in a car with the same ratios. Out of Turn 11 he looks like Verstappen, not like Antonelli. Second gear, 76 km/h at the bottom, full throttle 81 metres after the apex and 181 km/h 100 metres on. Both Red Bulls leave the hairpin 5 to 6 km/h down on the Mercedes. That part travels with the car.

Hadjar’s gain is elsewhere in the sector. He carries the highest minimum of the three through Turn 9, 150 km/h in fourth. Beyond that the trace offers no single place to point at. What it does establish is narrower and more useful. The deficit Verstappen carried out of Turn 11 was shared by his teammate. The rest of his middle-sector deficit was not.

That raises the question the gearing posed in the first place. There are three corners where the Mercedes drops to first and the Red Bull holds second: Turns 1, 11 and 15. At all three, 100 metres past each car’s own apex, Antonelli is 4 to 6 km/h quicker. The pattern is too regular to be a driver having a good corner. It travels with the two cars, whatever the cause.

What differs is the road after it. Out of Turn 1 Verstappen is ahead again 200 metres on, and he peaks at 285 km/h against 280 before the Esses. Through the Esses he touches the brake at 1,438 metres, from 250. Neither Antonelli nor Hadjar uses the pedal there at all. He still sets the fastest first sector of Q3, 25.254. Out of Turn 11 the Mercedes is still 4 km/h up at 200 metres, and the two are not level until 250. The deficit is the same size. It is simply paid at the start of the longest straight on the lap.

The last sector repeated the pattern in miniature. Through the flat kinks between Turn 15 and Turn 19 Verstappen peaked at 278 to Antonelli’s 272. At the four braked corners of the sector Antonelli carried the higher minimum every time, and at Turn 19 by 8 km/h, 202 to 194. The straights went to the Red Bull, the corners to the Mercedes, and the sector to Antonelli by 0.057.

The higher gear was there for Verstappen’s best exit and his worst. It cannot be the reason for both.

Turns 1, 11 and 15 are the corners where the Mercedes uses first gear and the Red Bull second. Right of zero is Antonelli quicker. At 100 metres he leads at all three. At 200 metres Turn 1 has turned to Verstappen, Turn 15 is down to 1 km/h, and Turn 11 still reads almost 4.

Sunday’s Chase Starts at the Exit of Turn 11

Saturday measured one lap each, run alone. On Saturday the Red Bull gave up a few km/h out of Turn 1 and had them back within 200 metres, and Sunday opens with the climb to that corner. After it, the order has to be held for 55 more laps. Sunday asks for 56 of them, with Verstappen alongside Antonelli on the front row and the championship within reach. Antonelli leads Russell by 102 points. A win settles the title in Austin, provided Russell finishes no higher than 10th and Hamilton no higher than 5th.

Qualifying located Antonelli’s advantage precisely. It was strongest from the bottom of Turn 11 to the highest speeds of the long straight. That is also where a race is most likely to turn. A car within one second at the detection point is entitled to override mode on the following lap. Override holds the full 350 kW of permitted electrical power to 337.5 km/h, where normal mode begins to taper at 290.

On that straight the gap between the two modes is large. At 330 km/h a car in normal mode is permitted 150 kW, and a car in override is still entitled to all 350. Both cars passed 330 there on Saturday. Nowhere else on the lap does a chasing car stand to gain as much.

Which turns the question around. To use that straight, Verstappen has to arrive at the detection point within one second of a car that leaves Turn 11 about 5 km/h quicker. Saturday says the hairpin is where the Mercedes pulls away, not where it can be caught. The ground Verstappen made up was in places override barely touches. The run out of Turn 1 and the short straights through the Esses and the stadium all end below 290, where normal mode already permits everything.

There is a tyre question underneath. Exits from first and second gear lean hardest on the rear axle, and Turn 11 asks for one every lap. The Esses ask for something else, sustained load on the front of the car, and the Esses sit in the sector Verstappen won. A traction advantage measured on new tyres over one lap is not the same thing as one that lasts a stint.

So Sunday tests the precise stretch of road where Saturday was won. Does the Mercedes still leave Turn 11 first on lap 40, on worn tyres, with a Red Bull in its mirrors? Or does the margin it builds there stay inside the one second that lets Verstappen ask the straight for help?

The straight where override is worth the most begins at the corner where the Mercedes was strongest.
