The Racing Bulls driver was three tenths faster through the opening sector. He finished fourth.
Oscar Piastri qualified on pole for the Dutch Grand Prix. Isack Hadjar was faster than him through the first sector.
Hadjar qualified fourth.
Key Finding
Hadjar was faster than pole-sitter Piastri through Tarzan. Then the rest of the lap happened.
How big was the sector gap?
HAD vs PIA — sector-by-sector breakdown
The first bar is the problem. Three tenths is not a rounding error — Hadjar genuinely won the opening sector.
▲ HAD faster▼ PIA faster
S1: -0.324s · S2: -0.089s · S3: -0.133s
Key Finding
Hadjar was faster than pole-sitter Piastri through Tarzan. Then the rest of the lap happened.
Hadjar's best lap was a 69.208. Piastri's was a 68.662. The difference is 0.546 seconds — just over half a second, in qualifying, at a circuit where you measure pole in hundredths.
The entire gap came from sectors two and three. Not because Hadjar was slow there. Because Piastri was faster everywhere else.
Key Finding
Hadjar was faster than pole-sitter Piastri through Tarzan. Then the rest of the lap happened.
Sector one ends at Turn 3. It contains Tarzan, the first-gear hairpin, where the Racing Bulls has historically been strong under braking. Hadjar took three tenths out of Piastri there.
Then came the rest of Zandvoort. The McLaren clawed back a tenth in sector two. Another tenth and a half in sector three, through the banked final corners where the car's aero platform does its work. Add it up and Piastri was on pole.
Where did the Racing Bulls lose it?
HAD (Lap 17) vs PIA (Lap 14) — fastest laps compared
Watch the gap open after the first major braking zone. The yellow line pulls clear through the middle sector and never comes back.
HAD (Lap 17)PIA (Lap 14)
Fastest laps: HAD Lap 17, PIA Lap 14.
Key Finding
Hadjar was faster than pole-sitter Piastri through Tarzan. Then the rest of the lap happened.
This was not a case of one driver nailing one corner and botching another. Hadjar's lap was clean. His sector one time was genuinely faster than the man who took pole.
The problem is that sector one is one-third of the lap. The other two-thirds belong to McLaren. At Monza next week, the Racing Bulls will get more opportunities under braking. Fewer banked corners. We'll see if that helps.
