A free Formula 1 simulator online — set the car up, qualify, then race it lap by lap from the pit wall.
GrandPrixSim is a free F1 simulator game: a full Grand Prix weekend condensed into a couple of minutes. Choose one of 24 real circuits, run a three-part qualifying session, and then watch the race unfold lap by lap — tyres going off, the pit window opening, a safety car bunching the field, rain arriving with fifteen laps to go. Pick a driver and you take the pit wall yourself.
If you searched for an F1 simulator online and landed on shops selling cockpits and steering wheels, this is the other thing you meant: an actual formula 1 simulation game that loads in a browser tab and costs nothing. No rig, no download, no account — a grand prix simulator you can be racing in about ten seconds. If what you wanted was an F1 race simulator game you could just open and play, that is what this is.
Lap times are built rather than rolled. A car's performance comes from its engine and aerodynamic ratings weighted by what the circuit asks for; the driver contributes pace, racecraft, tyre management, wet-weather skill and consistency. On top of that sits fuel load (cars are seconds slower on lap one than on the last lap), tyre life and the cliff beyond it, dirty air behind a car you cannot pass, DRS, pit-lane time loss, mechanical retirements weighted by team reliability, and a per-weekend form swing so the same car is not identical every round.
The result behaves like a season: qualifying spreads the field over roughly 1.5–3 seconds, one or two cars retire per race, safety cars appear at Baku and Singapore far more often than at Barcelona, and the title usually goes down to the final rounds.
All 22 drivers across 11 teams — McLaren, Mercedes, Ferrari, Red Bull, Williams, Aston Martin, Alpine, Racing Bulls, Audi, Haas and the new Cadillac entry. Every rating here is our own model, not official data.

A free online Formula 1 race simulator that runs in your browser. You choose one of 24 real Grand Prix circuits, run a full three-part qualifying session, then watch or control a lap-by-lap race with tyre wear, fuel load, pit stops, safety cars, DRS and changing weather.
Yes. No download, no sign-up, no account. It runs entirely in your browser, and nothing is stored on a server.
Yes. The timing screens scroll sideways on narrow screens and everything else reflows.
Both. Leave the driver slot empty for a pure simulation, or pick a driver and run their strategy from the pit wall.
Yes. The whole simulation runs in the page you are already on. There is no installer, no app store and no account, and nothing is stored on a server.
Each circuit is weighted for engine power, downforce, tyre degradation and how hard it is to overtake, so Monza rewards a strong engine and Monaco is almost impossible to pass at. Lap times build from car performance, driver ratings, fuel load, tyre life and traffic. Qualifying spreads the field by roughly one and a half to three seconds, which is what a real session looks like. The whole model is written up here.
The full 2026 grid: 22 drivers across 11 teams, including the new Cadillac entry. Ratings are our own model rather than official data.
Use the Championship Simulator for all 24 rounds, or the Career Simulator to live a single driver's whole career.
That depends on what you want from it. If you want the driving, a paid title with a wheel will always beat a browser tab. What this does better is the part those games skip: the strategy, the tyre calls and the championship maths. As a free F1 simulator online it is complete rather than a demo, and there is nothing to install to find out whether you like it.
About one to two minutes at normal speed, and a few seconds if you skip to the chequered flag. Qualifying is instant.
