Formula 1 is faster than IndyCar on almost every kind of circuit that exists. On every road course and street circuit, F1 laps seconds quicker, but IndyCar’s superspeedway qualifying speeds at Indianapolis sustain a higher average pace, corners included, than anything Formula 1 produces in normal racing.

• On the one track both series have raced in the same era, Circuit of the Americas in 2019, Formula 1’s pole lap was roughly 14 seconds faster than IndyCar’s over the same 3.41-mile layout.
• IndyCar’s 2026 Indianapolis 500 pole was set at 232.248mph (373.7km/h) as a four-lap average; the fastest Formula 1 has gone in the 2026 season so far is a single-point 315km/h (196mph) speed trap reading at the season-opening Australian Grand Prix.
• Formula 1’s edge comes from downforce and a 1,000-plus horsepower hybrid power unit in a 768kg car; IndyCar closes most of the gap through a shared spec chassis and engine formula that costs a fraction of what it takes to build an F1 car.

Is IndyCar Faster Than F1?​

No, not in the way that question is usually meant. Formula 1 is faster than IndyCar on every road and street circuit, typically by several seconds a lap, because of downforce levels and power-to-weight that IndyCar’s spec formula was never designed to match. Where IndyCar wins is narrower and specific: at Indianapolis Motor Speedway, IndyCars qualify and race at sustained speeds, all four corners included, that exceed anything Formula 1 records in ordinary race conditions, because ovals and ground-effect, low-drag bodywork let a less powerful car carry far more speed through a corner than an F1 car built for Monaco or Silverstone ever needs to.

The confusion usually comes from comparing the wrong numbers to each other. A single top-speed figure from either series, quoted without saying whether it came from an oval, a road course, qualifying or a race, tells a reader almost nothing, because both series vary far more by circuit type than they do by season. IndyCar at Indianapolis is a different car, in a different aero configuration, doing a different job to IndyCar at a street circuit like Long Beach, and the same is true of an F1 car at low-downforce Monza compared with high-downforce Monaco. Any comparison that skips past that distinction is not really answering the question.

Top Speed: IndyCar vs F1​

IndyCar’s headline number is its Indianapolis 500 qualifying speed. Alex Palou won the 2026 pole with a four-lap average of 232.248mph (373.7km/h), completing the four laps in 2 minutes 35.0066 seconds. That is still short of the outright Indy 500 qualifying record, 236.986mph (381.4km/h), set by Arie Luyendyk in 1996 and still standing as the track’s qualifying benchmark. Both figures are averages sustained through all four corners of the 2.5-mile oval, not a single straight-line peak. On a road course, IndyCar runs slower: at Circuit of the Americas in 2019, Will Power’s pole lap averaged 115.792mph (186.3km/h).

Formula 1’s fastest confirmed reading in the 2026 season so far is a 315km/h (196mph) speed trap at the Australian Grand Prix, set by rookie Arvid Lindblad, with faster, lower-downforce circuits still to come. Later in the year, Monza and Baku are projected to push that toward 350 to 360km/h (217 to 224mph), historically the calendar’s two fastest speed traps. The outright F1 speed record belongs to Valtteri Bottas, who reached 378km/h (234.9mph) driving a Williams FW38 in qualifying for the 2016 European Grand Prix in Baku, where the speed trap sits well before the braking zone. The fastest speed ever recorded in an actual Grand Prix race is lower but still faster than IndyCar’s Indianapolis average, 372.5km/h (231.4mph), set by the same driver and car at the 2016 Mexican Grand Prix.

Lap Times: What Happens On The Same Track​

The clearest test is a track both series have actually raced, in the same season, on broadly comparable machinery. That track is Circuit of the Americas, and that season is 2019, the only year IndyCar has raced there.

Valtteri Bottas took pole for the 2019 United States Grand Prix in 1 minute 32.029 seconds, and went on to win the race outright, with Lewis Hamilton’s second place enough to clinch his sixth world championship. Two months earlier, at the inaugural IndyCar Classic on the same layout, Will Power took pole in 1 minute 46.0177 seconds, an average of 115.792mph, before Colton Herta won the race for his maiden IndyCar victory, becoming, at 18 years and 359 days old, the youngest race winner in IndyCar history. The gap between the two poles is just under 14 seconds around an identical 3.41-mile, 20-turn circuit, a difference of roughly 15 percent on lap time alone. IndyCar has not returned to Circuit of the Americas since, so this comparison is anchored to 2019-specification cars on both sides, not current machinery, and it is the only same-track, same-era data point either series has to offer.

Why Is F1 Faster On Road Courses?​

Downforce and power-to-weight explain almost all of it. Formula 1’s 2026 cars run active aerodynamics, front and rear wings that switch between a low-drag mode for straights and a high-downforce mode for corners, on top of a 50/50 hybrid power unit producing more than 1,000 horsepower in a car with a 768kg minimum weight. That works out to roughly 1.3 horsepower for every kilogram the car weighs.

IndyCar’s spec aerodynamics generate far less downforce by design, and its twin-turbo V6, boosted by a supercapacitor hybrid system, produces somewhere in the region of 700 to 750 combined horsepower on a road or street course, in a car weighing around 1,775lb (805kg) without a driver or fuel on board. That puts IndyCar closer to 0.9 horsepower per kilogram, meaning an F1 car is carrying something like 40 to 50 percent more power for every kilogram it has to move. Add F1’s far higher cornering downforce and the seconds-per-lap gap at a track like Circuit of the Americas stops being surprising.

Where Is IndyCar Faster?​

Indianapolis is the exception, and it is an exception built entirely around one type of racing: high-banked, low-drag oval speed sustained for an entire lap. IndyCar’s superspeedway aero kit strips away almost all the drag a road-course setup would carry, banking through the four corners lets drivers carry far more of their straight-line speed into and through the turn than any road circuit allows, and the draft, running in another car’s slipstream, adds still more. That combination is why a 232mph four-lap qualifying average, corners included, is possible at all. Formula 1 has never raced a high-banked oval and its cars are not built to. A Formula 1 car’s peak speed, in isolation on a long straight, can beat that number, Bottas’s 378km/h (234.9mph) Baku reading converts to roughly 235mph, but that is a single instant before a heavy braking zone, not a sustained average through four corners for lap after lap. IndyCar’s advantage at Indianapolis is really an advantage in sustained cornering speed, not outright peak velocity.

IndyCar closes the gap further through pack racing. Running in the draft of another car reduces aerodynamic drag enough that speeds through the middle of a superspeedway pack routinely exceed what any single car could hold alone, part of why qualifying and race-day speeds at Indianapolis differ so much from anywhere else on the calendar. Qualifying runs are set alone, against the clock, so Palou’s 232.248mph and Luyendyk’s 236.986mph both came without a tow. In race conditions, with a full field running nose to tail at Indianapolis, cars can carry even more speed through the draft than either of those solo qualifying laps, which is part of why the closing laps of the Indy 500 are consistently among the fastest, and most dangerous, in the sport.

IndyCar’s push-to-pass system adds a second layer on top of that. Drivers get a limited allowance of extra horsepower per race, deployed at the push of a button, primarily on road and street courses rather than ovals, stacking on top of the hybrid boost to create short bursts of extra pace for overtaking. It is a much blunter tool than Formula 1’s active aerodynamics, but it serves a similar purpose: giving a trailing car a defined, rules-based way to close a gap that pure pace alone would not close.

How Different Are The Cars?​

The two series start from opposite design philosophies. IndyCar is a spec series: every full-time entry runs the same Dallara chassis, and teams choose between two homologated engine suppliers, Honda and Chevrolet, rather than building their own. Formula 1 is the opposite, eleven teams each design and build their own chassis and aerodynamics from scratch every season, under a shared technical and financial rulebook.

That difference shows up directly in cost. A single Formula 1 car costs its team roughly $15 to $22 million just to build, before a lap is driven, inside an overall budget cap of $215 million a year covering everything else the team spends on performance. Running a competitive IndyCar for an entire season, chassis, engine lease and tyres included, is put by independent cost analyses at somewhere between $8 million and $13 million total, with the engine lease alone running upwards of $1.5 million a year and tyres costing roughly $100,000 a month. IndyCar’s spec formula does not just keep the racing closer, it keeps an entire season of racing cheaper than the physical materials in one Formula 1 car.

That gap is deliberate rather than accidental. IndyCar’s single-chassis, two-engine-supplier rulebook exists specifically to stop a wealthy team simply outspending the field on aerodynamics, the way an F1 constructor can. A midfield IndyCar team and Team Penske are racing genuinely similar equipment; a midfield F1 team and Ferrari are not, even under the cost cap, because the cap limits how much each team can spend on its own car, not how good the results of that spending can be.

Of the three major series that have raced regularly in the United States, NASCAR sits closer to IndyCar in that respect, a shared chassis platform and cost controls built to keep grids close, while Formula 1 remains the outlier, built for bespoke aerodynamics and road and street circuits rather than the oval racing IndyCar and NASCAR both grew up on.

Are Both Series Hybrid Now?​

Yes, though the two hybrid systems operate at very different scales. IndyCar introduced its first hybrid system mid-way through the 2024 season, debuting at Mid-Ohio. Developed with MAHLE, it stores energy in 20 supercapacitors housed in the bellhousing between the engine and gearbox, adds roughly 100lb (45kg) to the car, and can fully charge and discharge in about 4.5 seconds, adding around 60 horsepower on top of the engine’s own output.

Formula 1’s 2026 power units are hybrid on a much bigger scale. Rather than a supplementary boost, the 2026 rules split output almost exactly 50/50 between the internal combustion engine and the electric motor, the MGU-K, which now produces 350kW, roughly three times the 120kW it produced under the previous generation of power units. Both series are hybrid now, but IndyCar’s system adds a fixed, modest boost on top of a combustion engine that still does almost all the work, while F1’s electric motor is doing close to half the job.
