The spiritual home of Brazilian motorsport
The Autódromo José Carlos Pace — known universally as Interlagos — is one of the most beloved circuits in Formula 1. Located in the Interlagos neighborhood of São Paulo, the 4.309-kilometer track sits between two reservoirs, Guarapiranga and Billings, which create a microclimate that can shift from blazing sun to torrential rain within a single stint. The サーキット features 43 meters of elevation change across the lap, with the lowest point at the Junção corner and the highest on the main ストレート near the pit entry. That grade — roughly equivalent to a 10-story building — is unusually large for a permanent サーキット and plays a 重要 role in how tyre temperatures, brake wear, and fuel load interact over a レース distance.
The original Interlagos サーキット was built in 1940 as a 7.96-kilometer road course winding through the surrounding streets. It hosted the first Brazilian Grand Prix in 1972 and joined the F1 calendar in 1973, when Emerson Fittipaldi won the inaugural world 選手権 レース in front of a home crowd. The サーキット was shortened to its current layout in 1990, redesigned by architect Oscar Niemeyer's associate, and significantly renovated before the 1990 シーズン. A major resurfacing in 2014 addressed the notoriously bumpy tarmac that had become a defining — and divisive — feature of the track. Some drivers loved the bumps for the challenge they added; others argued the rough surface was destroying reliability without adding genuine racing value.
Every ドライバー who has raced at Interlagos rates it among their favorites. Ayrton Senna called it "the track that made me." Lewis Hamilton has described it as "one of the great old-school tracks" where the ドライバー still makes more difference than the car. The combination of high-speed corners, blind crests, and the electric atmosphere makes it one of the most complete tests of ドライバー skill on the calendar.
The corners that define Interlagos
The Senna S — a fast left-right-left combination named after Ayrton Senna — is the most famous sequence at Interlagos. Entry speed is around 290 km/h before the initial left-hander, with drivers scrubbing speed through a compression that loads the car with an extra 1.5G of vertical force. It tests a car's mechanical grip and a ドライバー's ability to carry momentum through multiple direction changes. The camber in the middle of the sequence can catch drivers out: carry too much speed into the left and the car understeers wide on exit, losing half a second before the following ストレート even begins.
The Descida do Lago, a long downhill right-hander that follows the Senna S, is one of the fastest corners in F1 at roughly 260 km/h through the エイペックス. The descent drops nearly 10 meters from entry to exit, which means the car is accelerating under gravity even before the ドライバー applies throttle. This is where rear tyre blistering often begins — the sustained lateral load on the right-rear tyre through this long corner heats the surface compound faster than the left side of the car.
The Ferradura and Laranjinha sequence in the middle sector is a flowing, high-speed combination that rewards エアロダイナミック efficiency. Cars with stronger rear ダウンフォース can carry 5-8 km/h more through here, which translates to a time gain of 0.1-0.2 seconds across the full sequence. The final sector, with its tight Mergulhinho ヘアピン and the uphill run to the finish line, is where races are often won and lost. The Mergulhinho is deceptively difficult: the approach is downhill, the エイペックス is blind, and the exit climbs sharply, which means the car pitches forward under braking and then unloads the rear on exit. Drivers who misjudge the braking point here either lock a front wheel into the ヘアピン or get on the power too early and spin the rear on the uphill exit.
Why Interlagos produces drama
Interlagos has hosted some of the most dramatic races in F1 history. The 2003 Brazilian Grand Prix stands as one of the most chaotic races ever: a rainstorm turned the track into a skating rink, with Mark Webber crashing heavily and Fernando Alonso hitting debris from the crash at over 200 km/h. The レース was red-flagged and the result was contested for hours, eventually giving Kimi Raikkonen the win. The 2008 Brazilian Grand Prix, where Hamilton won the 選手権 on the final corner of the final lap by overtaking Timo Glock for fifth place, remains the most famous 選手権 decider in the sport's history — a finish that required Hamilton to gain exactly one position in the final 800 meters.
The 2012 レース, where Sebastian Vettel survived a first-lap collision with Bruno Senna that spun him to the back of the field before fighting through to clinch his third consecutive title, showed how Interlagos can punish and reward in equal measure. The 2016 レース produced a maiden victory for Max Verstappen in mixed conditions, with the 19-year-old delivering a masterclass in ウェット-weather car control through the middle sector. In 2019, Verstappen won again after passing Lewis Hamilton around the outside of Turn 1 with six laps remaining — a move that required precise positioning on the dirty side of the track.
The 2021 Sprint format weekend saw Hamilton take a dominant win despite starting tenth due to a グリッド penalty, demonstrating how the サーキット's DRS zones and heavy braking areas allow faster cars to recover from poor グリッド positions. In 2023, Lando Norris finished second to Verstappen after a dramatic late-レース battle through the Senna S, where both drivers pushed the limits of grip through the blind crest.
The サーキット's layout contributes to the drama. The long main ストレート creates DRS overtaking opportunities into Turn 1, while the technical middle sector rewards ドライバー skill and prevents faster cars from simply cruising away. The unpredictable São Paulo weather adds another variable — rain can fall on one part of the サーキット while another remains dry, because the track sits between two bodies of water that generate localized weather patterns. A チーム that pits for intermediates too early can lose 20 seconds if the rain moves away; a チーム that waits too long risks aquaplaning into a barrier.
Interlagos in the 2026 era
In the 2026 era, with lighter cars and less ダウンフォース, Interlagos will feel fundamentally different. The new パワーユニット regulations deliver more electrical energy — up to 350 kW from the MGU-K alone, roughly double the 2025 figure — which changes the acceleration profile out of slow corners. The Mergulhinho ヘアピン, where cars crawl to around 80 km/h, will become a 重要 traction zone where the deployment strategy of the electrical system determines who gains or loses position on the uphill run.
The reduced エアロダイナミック ダウンフォース will make the high-speed corners like Descida do Lago and the Ferradura sequence more demanding. Drivers will need to rely more on mechanical grip and car balance, which should widen the gap between the best and worst setups. The lighter cars — the minimum weight drops by roughly 30 kg — will be more nervous under braking, making the Turn 1 complex at the end of the main ストレート even more of a lottery in the opening laps.
The anti-clockwise direction, which already places unique demands on drivers' necks, will become even more challenging. The left-hand corners load the right side of the neck, and the sustained G-forces through the Senna S and Descida do Lago can exceed 4G for several consecutive seconds. In the 2026 cars, with less エアロダイナミック stability, the physical demand of catching oversteer corrections while fighting neck fatigue will separate the physically prepared from the rest.
But the fundamental character of Interlagos will remain the same: a サーキット that rewards bravery, rewards skill, and produces drama. The elevation, the weather, the compressed lap length, and the passionate crowd will continue to make Brazil the レース that every ドライバー wants to win.

Where Fans Get Confused
Interlagos is not dramatic only because it rains. Elevation, the Senna S, a long uphill ドラッグ to the line and a compact lap make traffic and tyre phase changes unusually powerful even in the dry. A car that is strong in the middle sector may be vulnerable into Turn 1 because the DRS zone on the main ストレート neutralizes エアロダイナミック advantages. The compact lap length — one of the shortest on the calendar at around 70 seconds — means lapped traffic arrives sooner and disrupts rhythm more frequently than at longer circuits.
Another common mistake is assuming that the fastest qualifier will win. The 2012 and 2016 races showed that Interlagos punishes one-dimensional strategies. The tyre allocation, weather pattern, and セーフティカー probability all create opportunities for teams willing to take a different approach. The undercut at the first ピットストップ is powerful because the pit lane is short and the out-lap on fresh tyres gains nearly a second through the middle sector, but overcutting can work if the track surface is rubbering in and the ドライバー in front is managing tyres conservatively.
Watch the レース in clusters. The opening laps through the Senna S set track position, the middle stint exposes tyre management, and late weather or safety cars can reset everything. Interlagos rewards teams that stay flexible rather than teams that only chase one-lap speed. Track the battle in the middle sector specifically — a ドライバー who is losing time through the Ferradura sequence but gaining on the main ストレート is likely managing a balance issue that will worsen as the fuel load drops.
