Preparing your Formula Dream journey
Jeddah holds the record at over 250 km/h average, but we measured every 2026 street race ourselves. The gap between the fastest and slowest is 75 km/h.
Jeddah is the fastest street circuit Formula 1 has ever raced on, averaging comfortably above 250 km/h a lap. It is not close, and it is not on the 2026 calendar.
That makes the more useful question a different one: how fast are the street circuits F1 actually races now? We measured them, taking the fastest legal qualifying lap at every 2026 round and dividing the real telemetry distance by the real lap time.
| Circuit | Average lap speed | Fastest lap |
|---|
| Melbourne | 238.1 km/h | 1:18.518 |
| Montreal | 213.8 km/h | 1:12.578 |
| Monaco | 163.0 km/h | 1:12.051 |
Melbourne is the fastest street-type circuit raced in 2026 at 238.1 km/h. Monaco, at 163.0 km/h, is 75.1 km/h slower. That is a bigger gap than exists between Monaco and a Formula 2 car.
A caveat on definitions, because this is where most articles quietly cheat. Albert Park is a parkland circuit on public roads, and whether it counts as a street circuit is genuinely arguable. Montreal is a semi-permanent circuit on an island. Monaco is the only one of the three nobody disputes. If you accept only the strictest definition, the fastest street circuit F1 has raced in 2026 so far is Montreal at 213.8 km/h.
The 2026 season is not finished, and the fast ones are ahead:
We expected Baku to beat Melbourne, then measured it and it does not. Baku's fastest qualifying lap averaged 211.3 km/h in 2025 and 210.8 in 2024, well short of Melbourne's 238.1. Despite owning the longest uninterrupted full-throttle run on the calendar at 1.842 km, the castle section takes back everything the straight gives: nine braking events a lap and a slowest point of 72 km/h.
That left Las Vegas as the likeliest challenger, and we have now measured it. The answer needs care.
Las Vegas averaged 239.4 km/h on its fastest dry qualifying lap, which is nominally above Melbourne's 238.1. But those two laps were set by different generations of car, and comparing across generations is how most speed rankings quietly mislead. Measured on the same cars, in the same season, Melbourne averaged 247.4 km/h and Las Vegas 239.4. Melbourne is genuinely the quicker circuit.
What Las Vegas does own is peak speed. Its fastest lap reached 347 km/h, identical to the fastest lap ever set at Monza, which is not a number street circuits produce. It also runs at 81.3% full throttle, the highest of any street circuit we have measured. It is second in this category behind Jeddah, and the reason is not the straight, it is that the rest of the lap never gets slow enough to cost real time: its slowest corner is still taken at 89 km/h.
One warning for anyone else measuring it. The 2025 Las Vegas qualifying session was fully wet, 282 laps on full wets and 93 on intermediates with no slick running at all, and it produces an average of 204.9 km/h. That figure measures rain, not the circuit.
Jeddah Corniche Circuit is the outlier that makes the category confusing, so it is worth understanding.
It is 6.174 km long with 27 corners, which sounds slow until you look at the corners themselves. Most of them are extremely fast, flowing sequences taken near flat, separated by walls rather than run-off. The circuit was deliberately designed to produce high average speed, and it does: quicker on average than most permanent circuits, including several that are not street circuits at all.
That is the point worth taking away. A street circuit is not automatically slow. What makes Monaco slow is not that it runs on public roads, it is that the corners are tight and the lap is short. Jeddah runs on public roads too and averages nearly 90 km/h more.
Our measurements across the whole 2026 season point at one number more than any other: how much of the lap the driver spends at full throttle.
At Monaco, the fastest qualifying lap was at full throttle for just 37% of its duration, the lowest of any circuit we measured. At Spa, the fastest circuit of the season so far, it was 68%. Nearly double.
Corner count barely correlates with speed at all. Jeddah has 27 corners and is fast. Monaco has 19 and is the slowest circuit in Formula 1. What matters is whether the corners let you keep your foot down, and street circuits vary enormously on that.
The full ranking of every circuit we measured, street and permanent, is in the fastest F1 circuits.
One more thing worth knowing before comparing our numbers to older figures.
The 2026 regulations cut downforce substantially, and the cars are measurably slower than the generation before. Pole laps this season are around 3% slower than 2025 at the circuits raced in both. So a historical street circuit record set by an earlier car is not directly comparable to a 2026 measurement, which is exactly why we publish the year alongside every number. The measurement is in are F1 cars getting faster.
Baku is round 15, and on our measurements it should be the fastest street circuit of the 2026 season.
The Formula Dream app runs a live Dashboard through every session: every car on the circuit map, and a timing tower with lap times, gaps and intervals, tyre compound and age, plus flag and safety car alerts as race control calls them. Street circuits are where safety cars decide races, and where a lap time that looked safe stops being safe. You also get live driver radio as it is broadcast, and every FIA document of the weekend as it is published.

Jeddah Corniche Circuit, which averages comfortably over 250 km/h a lap and is the fastest street circuit Formula 1 has raced. It is not on the 2026 calendar. Of the street and semi-street circuits raced in 2026 so far, Melbourne is quickest at a measured 238.1 km/h.
Yes. We measured Monaco's fastest 2026 qualifying lap at 163.0 km/h average, the lowest of any circuit on the calendar, and 75.8 km/h slower than Spa at the top of the list.
Because of how much of the lap is spent at full throttle rather than because of the walls. Monaco's fastest lap was at full throttle 37% of the time; Spa's was 68%. Jeddah has 27 corners and is fast because most of them are taken near flat.
Monaco, Melbourne and Montreal have been raced, with Madrid, Baku, Singapore and Las Vegas still to come. Madrid is a hybrid of street sections and a permanent circuit rather than a pure street track.
From Formula 1's own timing and telemetry. We took the fastest legal qualifying lap at each 2026 round, excluded deleted laps, and divided the real distance recorded by the car by the real lap time.
Losing DRS was supposed to kill overtaking. Across nine dry circuits raced in both seasons, on-track position changes fell by 3.9%. That is all.
