With every new Formula 1 season, while die-hard enthusiasts debate aerodynamic regulations and tire compounds, casual fans are often stuck wondering about a much simpler, human question. Does an F1 driver pee in his suit? Can they pee during the race? And has anyone ever done a poo in the cockpit?
Well, we’re going to answer those questions with the cold, hard (and wet) facts. But before we get ahead of ourselves, let’s answer the big question.
Does an F1 driver pee in his suit?
Yes. Usually, a Formula 1 race lasts between 90 minutes and two hours. Unlike a road trip, there are no rest stops. This means that if nature calls while a driver is strapped into the chassis, they have no choice but to answer it right there in the cockpit. While not every driver does it, many have admitted that when you gotta go, you go.
What happens when an F1 driver pees in their suit?

Drivers have a drink system that pumps fluid into their mouths via a button on the steering wheel, but there is no reverse system for waste. That would be heavy, intrusive, and mechanically complex. So, instead, a racing driver simply wets their suit.
It sounds uncomfortable—and it is—but the extreme environment of a Formula 1 cockpit changes the physics of the situation significantly.
The Science: Why it “Disappears”

Formula 1 cars are incredibly hostile environments. Drivers are not just sitting; they are athletes performing under immense stress. Here are the numbers that explain why peeing in the suit isn’t as messy as you might think:
- Cockpit Temperature: The temperature inside the cockpit regularly averages 50°C (122°F) and can spike up to 60°C (140°F) at humid tracks like Singapore.
- Weight Loss: Drivers can lose between 2kg to 4kg (4.4lbs – 8.8lbs) of body weight during a single race, almost entirely through sweat.
- Evaporation: Because the driver is encased in a fire-retardant suit sitting inches from a hot engine, the liquid evaporates rapidly. By the time the car returns to parc fermé, the suit is usually just dry and crusty with salt, indistinguishable from sweat.
Lewis Hamilton’s view on peeing during an F1 race
7-time world champion Lewis Hamilton famously spilt the beans on a certain legend of the sport regarding this topic:
“You’re supposed to go in your suit, but I can’t do it. I’ve never done it. But there are drivers that do,” Hamilton told the press.
“The driver that used to drive for the team was Michael Schumacher, I don’t know if anyone’s heard of him, but legend racing driver… my mechanics told me he peed every single time he was in the car.”
Daniel Ricciardo: “Every Kerb Stings”
Fan-favorite Daniel Ricciardo added another layer of grim reality to the situation. Speaking on the topic, he confirmed he has never been able to do it, citing the pain involved in holding it:
“I haven’t done it. You generally just hold on until the end… You’re so tense, and if you just slightly relax to go, it’s hard. You hold on, and every little kerb you hit stings.”
What about “Number Two”? Do drivers poop in their suits?
While urinating is an accepted (if gross) reality of the sport, defecating in the suit is a different story entirely. The short answer is No, but there is a fascinating biological reason why.
The “Pucker Effect”
While relaxing the bladder is possible under stress, the body’s “fight or flight” response – fueled by massive spikes in adrenaline – generally shuts down the digestive system’s lower functions. Combined with the immense G-forces (up to 5G under braking) that clamp the driver into the seat, it is physically nearly impossible to relax the sphincter muscles required to poop while driving a Formula 1 car.
As David Coulthard eloquently put it: “Adrenaline and fear is a great laxative… but [during the race] it is very difficult to pass wind in a race car because that involves relaxing one’s sphincter.”
The Kimi Räikkönen Strategy
Drivers take extreme measures to ensure they are empty before the race starts. The most famous example of this occurred at the 2006 Brazilian Grand Prix.
When football legend Pelé was presenting Michael Schumacher with a lifetime achievement award on the grid, Kimi Räikkönen was conspicuously missing from the broadcast. When Martin Brundle later asked Kimi live on TV where he had been, the ‘Iceman’ gave a legendary response:
“I was having a s**t.”
It was blunt, it was live, and it proved that timing is everything.
Frequently Asked Questions (FAQ)
Do F1 drivers wear diapers?
Generally, no.
While this is a common rumor, F1 drivers usually wear fireproof underwear beneath their suits, not adult diapers. The races are short enough (under 2 hours) that most drivers can hold it. However, admitted exceptions do exist. Mark Webber and Rubens Barrichello have alluded to the safety and comfort of diapers in the past, but it is far from standard practice on the modern grid.
Do F1 drivers pee in the cockpit?
Yes.
As discussed, the extreme heat (up to 50°C) means any fluid tends to dry up before the end of the race. Engineers and mechanics, however, are often the ones who find out the hard way when cleaning the seat post-race.
Do F1 drivers poop during a race?
No.
Drivers follow strict diets to ensure their bowels are empty before lights out. Unless a driver is suffering from severe food poisoning or illness (which has happened, but usually leads to retirement), the adrenaline and G-forces prevent it from happening.
Conclusion
Yes, F1 drivers do pee in their suits while racing. And no, they generally do not poop. It is a mix of extreme dehydration, immense heat, and sheer practicality. While icons like Michael Schumacher reportedly embraced the “freedom,” others like Hamilton and Ricciardo find it physically or mentally impossible. But one thing is certain: if you see a driver rushing away from the podium ceremony, they probably didn’t follow Kimi Räikkönen’s advice.
