F1 3D race replay | StatChecked

How this works

What it shows

The 3D replay rebuilds any session from 2018 onwards from the cars’ recorded positions. Alongside it you get a timing tower, the flag state, race control messages and live telemetry for the drivers you choose. It’s for seeing where a gap closed or a move was made.

Where the data comes from

Cars carry transponders that report their position a few times a second, and these readings are published with the official timing data. Seasons from 2023 come from OpenF1, and 2018 to 2022 from a copy we prepared with FastF1, together with lap times, tyres, pit stops and race control messages. The scenery around the circuit comes from OpenStreetMap.

How it’s put together

The track is the fastest lap’s position trace, including height. Every car’s readings are placed on a shared half-second clock. A car with no reading within five seconds of a frame disappears, because it’s in the garage or out of the race. Races open at lights out. Drag the slider back to see the formation lap.

The tower is rebuilt from lap-line crossings. In a race, cars are ordered by laps completed and then by who crossed the line first. Gaps are the difference in crossing times on the same lap, and lapped cars show “+1 L”. In practice and qualifying, cars are ordered by their best lap so far. For 2023 onwards, the flag state is worked out from race control messages.

To place the scenery, we line up the circuit outline with the roads around the venue. If the best fit is off by more than about 15 metres, we show no scenery rather than misplaced scenery.

Tips and caveats

Click a car, or its row in the tower, to follow it with the Follow camera. Use Top for an overview.
When the session has car telemetry, the chart button next to a driver in the tower pins their live speed, gear, throttle and brake beside the replay. You can pin up to four drivers.
Playback runs from real time (1×) up to 60×.
Gaps change only when a car crosses the line, so they step rather than tick smoothly.
Between readings cars move in straight lines, so on a tight corner a car can appear to clip the inside.
Elevation is exaggerated 2.5× and the cars 1.4×, so the picture isn’t to scale.
