It’s the smell first. Before you even see the cars or hear the high-pitched scream of a power unit bouncing off the rev limiter, there’s this thick, heavy scent of barbecue smoke and high-octane fuel hanging over the neighborhood. Most modern racetracks are built in the middle of nowhere, surrounded by pristine parking lots and sterile glass hotels. Not here. The Autódromo José Carlos Pace is literally shoved into a bowl between two lakes in a densely packed residential district of São Paulo. It’s cramped. It’s loud. It’s slightly crumbling at the edges.
And honestly? That’s exactly why every driver on the grid secretly loves it.
You probably know it better as Interlagos. That’s the name that stuck because, well, the track sits "between lakes." But the official name honors José Carlos Pace, a brilliant Brazilian driver who won his only Grand Prix here in 1975 before tragically dying in a plane crash a few years later. The track is a relic that shouldn't work in 2026, yet it remains the most unpredictable weekend on the FIA calendar.
The Anti-Modern Circuit
Modern tracks are designed by computers to be safe. They have massive asphalt run-off areas that look like parking lots. If you make a mistake, you just drive wide and come back on. At the Autódromo José Carlos Pace, if you miss the apex at the Senna S, you’re bouncing over a curb that wants to launch you into the stratosphere.
The track runs anti-clockwise. That might sound like a minor detail, but for a Formula 1 driver, it’s a literal pain in the neck. Most tracks go clockwise, so drivers’ neck muscles are conditioned to handle right-hand G-forces. By the time they get halfway through a race at Interlagos, their heads are heavy. Their left-side neck muscles are screaming. It’s physical. It’s raw.
Then there’s the altitude. It sits about 800 meters above sea level. While that’s not quite the "thin air" nightmare of Mexico City, it’s enough to mess with aerodynamics and engine cooling. The air is thinner, meaning the cars have less downforce, making them twitchy. It feels like the car is floating. You have to wrestle it.
The Microclimate Madness
You can’t talk about the Autódromo José Carlos Pace without talking about the weather. It is a chaotic character in every race. Because of the topography of São Paulo and the surrounding lakes, storms don't just "arrive"—they materialize out of nowhere.

I’ve seen it happen. One minute it’s 30 degrees Celsius and the track is melting. Ten minutes later, there’s a wall of water so thick the drivers can’t see their own steering wheels.
Remember 2008? Lewis Hamilton winning his first title on the very last corner of the last lap because a sudden rain shower turned the track into an ice rink? That wasn't scripted. That was just Interlagos being Interlagos. Or 2012, when Sebastian Vettel got spun around on the first lap, faced the wrong way while the entire pack screamed past him, and somehow fought back to win the championship in a broken car.
The track creates drama because it’s short. At only 4.3 kilometers, the lap times are incredibly tight. In qualifying, a tenth of a second isn't the difference between first and second—it's the difference between pole position and sixth place. There is no room for a "lazy" lap.
Why the Fans Are Different
The Paulistanos don’t just watch the race; they vibrate with it. The grandstands at the Autódromo José Carlos Pace are situated incredibly close to the tarmac. In the "S" do Senna, you can practically see the sweat on a driver’s visor.
There is a specific kind of roar that happens here. It’s a rhythmic, football-stadium-style chanting. It started with Emerson Fittipaldi, grew into a religion with Ayrton Senna, and continues today even when there isn't a Brazilian on the top step of the podium. They adopted Lewis Hamilton as an honorary citizen for a reason. They respect the hustle.
It’s also one of the few places left where the track invasion feels authentic. When the gates open after the checkered flag, the sea of yellow and green that floods the main straight is a sight that modern, sterilized circuits in the Middle East or the US just can't replicate. It feels human.

Technical Nuances Most People Miss
The Subida dos Boxes. That’s the long, uphill left-hand sweep that leads onto the main straight. It looks easy on TV. It isn't.
Because it’s an uphill climb, engine power is everything, but so is traction. If you get a poor exit out of Junção (the turn before it), you are a sitting duck for the entire length of the straight. You’ll see drivers desperately weaving to break the slipstream.
- The Bumps: The soil underneath the track is unstable. Despite constant resurfacing, the track develops "heaves." Drivers have to memorize where the bumps are every single year because they move.
- The Kerbs: You have to use them to be fast, but if you take too much, the car bottoms out on the skid block, and you lose all grip.
- The Pit Entry: It’s one of the most dangerous and awkward in the world. You’re peeling off a high-speed curve while other cars are accelerating past you at 300km/h.
The Ghost of Ayrton Senna
You can’t escape Senna at the Autódromo José Carlos Pace. His influence is everywhere, from the murals on the walls to the "Senna S" (Turns 1 and 2), which he actually helped design when the track was shortened and remodeled in 1989-1990.
His 1991 victory here is the stuff of legend. His gearbox was failing. He lost third, fourth, and fifth gears. He finished the race using only sixth gear, his arms cramping so badly from the physical effort of manhandling the car that he had to be lifted out of the cockpit. He didn't do that for the points. He did it because he was at Interlagos. The track demands that kind of sacrifice.
Realities of the Venue
Is it perfect? No. The paddock is notoriously small. Mechanics have to work in cramped garages that look like they belong in the 1970s compared to the palatial setups in Abu Dhabi. Security has historically been an issue outside the gates. The local government is constantly fighting to keep the race, as other Brazilian cities—like Rio—have tried to steal the Grand Prix away.
But every time there's a threat to move the race, the drivers revolt. They don't want a shiny new track in a forest. They want the bumps. They want the unpredictable rain. They want the 15-meter elevation change from the lowest point to the highest point.

Actionable Insights for the Fan or Visitor
If you’re planning to head to the Autódromo José Carlos Pace, or even if you’re just watching from home, there are a few things to keep in mind to actually appreciate the chaos.
First, watch the tires. Interlagos eats rear tires for breakfast. The long, loaded corners like Ferradura put immense heat into the rubber. If a driver is sliding even a little bit early in the stint, they are going to be a "mobile chicane" by the end of it.
Second, if you're visiting, don't just sit in the main grandstand. The "G" section is where the most hardcore fans are. It’s louder, grittier, and offers a better view of the back straight where most of the overtakes happen. Also, bring a poncho. Even if the forecast says 100% sunshine, it’s going to rain. It always rains.
Finally, appreciate the history. This isn't a "utility" circuit. It’s a living museum. When you see a car fly through the Arquibancadas, you’re watching them follow the same basic geometry that’s existed since 1940. It’s a miracle it still exists in the modern world.
How to experience the circuit today:
- Sim Racing: Most modern sims (iRacing, Assetto Corsa) have laser-scanned versions. Drive it. You’ll realize how blind some of the apexes are.
- Track Days: Local clubs in São Paulo do hold open days. If you're in Brazil, it's worth the pilgrimage just to walk the pit lane.
- Museums: Check out the various tributes to Pace and Senna scattered around the neighborhood of Interlagos.
The Autódromo José Carlos Pace isn't just a strip of asphalt. It’s a pressure cooker. It forces mistakes, rewards bravery, and reminds everyone that sometimes, the old ways are still the best ways to race.
