FP1 Monza: Ferrari dominates, but the heatwave is the real test

Hook: 1:26.153 — the number that topped the first practice session at Monza.

When Charles Leclerc locked in his fastest lap of FP1 at 1:26.153, the provisional timing screen showed a nearly perfect picture for Ferrari: a 1-2 lockout on the fastest circuit on the calendar. But data is never in a hurry, and people always are. Before calling this a declaration of sovereignty from the Scuderia, we need to look at what FP1 actually says — and more importantly, what it deliberately hides.

Context: A mixed running session, a weather threat.

Monza is the lowest-downforce circuit on the calendar, where top speed and aerodynamic efficiency on the long straights decide everything. FP1 is rarely strategy-indicative: teams run mixed programs — aero tests, long runs, setup experiments — and fuel levels are never disclosed. So the 0.197-second gap of Lewis Hamilton behind teammate Leclerc, or the 5th place of championship leader Kimi Antonelli at +0.636s, are merely fragments of an unfinished picture.

Thursday morning's most notable moment was not on track but in the FIA's heat hazard declaration due to the European heatwave. This is the variable that could reshape the entire weekend.

Core: What the data says — and what it doesn't.

Let's start with what the timing sheet confirms. Leclerc led with 1:26.153, Hamilton within two-tenths — an almost perfect internal balance between the two Ferraris, suggesting similar setups and possibly similar fuel loads. Russell was 3rd for Mercedes, while Racing Bulls' Lawson surprised with 4th — a notable result for a midfield team exploiting the low-drag package well.

But here is the blind spot I want to stress after years of watching practice sessions: FP1 almost never reflects true race pace. A low-fuel glory run can push a Racing Bulls to 4th without revealing long-run capability. Based on my experience following these races, I only trust one thing in FP1: this order will be completely shuffled once qualifying runs with standardized fuel loads.

What's more intriguing is Antonelli — described as the championship leader — only 5th, 0.636s off. If he is the title leader, that gap is concerning; but in an FP1, it concludes nothing about race pace. Mercedes may have run a longer program, heavier fuel, or simply prioritized data collection over lap time.

Contrarian: The heat is the real test.

While the media may focus on Ferrari's display, I argue the weekend's most important signal is not in FP1 but in the FIA's heat warning. A European heatwave at Monza — where high-speed corners generate enormous thermal energy — will force teams to open cooling louvers, increasing drag and directly hurting top speed on the long straights.

This is an unquantified trade-off: opening louvers to cool means losing straight-line speed — at Monza, where top speed is king. If the heat persists, a two-stop strategy or extended tire management may become necessary. More importantly, the DRS train effect on the straights could be amplified when tires overheat, reducing overtaking chances — an ironic paradox for a circuit famous for overtaking.

Takeaway: Don't read FP1 as a conclusion.

FP1 at Monza gave us a snapshot, not a full portrait. Ferrari looks well-suited to the low-downforce configuration, Hamilton is adapting reasonably to the new car, and Racing Bulls showcased an effective aero package. But the weekend's real question is not who is fastest in a low-fuel lap — it's which car withstands Monza's heat better. And the answer, as always, will not come from Friday's timing sheet, but from long runs in extreme temperatures.

At 60, I no longer believe in luck, only in numbers that haven't spoken yet. And this weekend's unspoken numbers are in the cooling louvers, not on the FP1 leaderboard.
