Monza has never been a gentle place to race a Formula 1 car. This weekend, it will be brutal.
The Italian Grand Prix has been officially classified as a heat-hazard event, with temperatures forecast to surge past 31C during Sunday’s race and hover in the mid-30s around the Autodromo Nazionale all weekend. Around Milan, the mercury has already given a taste of what’s coming, hitting 36C near Linate airport on Wednesday afternoon.
For the drivers, that label is more than a line in a race director’s notes. It changes how they suit up, how they prepare, and how their teams balance performance against survival.
Under the ruling, drivers are permitted to use a cooling system that pumps chilled liquid – typically glycol-based – through a network of tubes in a fireproof top worn beneath their race overalls. It’s a discreet bit of kit, hidden under layers of Nomex, but on a day like this it can be the difference between managing the heat and being overwhelmed by it.
There is, though, a twist. The system is optional, not compulsory. Any driver who decides to tough it out without the cooling vest must pay a clear price: 5kg of ballast added to the car.
In a sport where engineers agonise over grams, 5kg is enormous. It’s lap time. It’s tyre wear. It’s braking distance. Teams will have to decide whether the raw, unencumbered performance is worth exposing their driver to cockpit temperatures that can soar far beyond the already fierce ambient heat.
Monza’s long straights and heavy braking zones demand commitment at the best of times. This weekend, as the heatwave lingers over northern Italy, commitment alone won’t be enough. The grid will line up not just for a flat-out run through the Temple of Speed, but for a test of endurance that starts long before the lights go out.
