About Ghost Lap
Two laps can finish a tenth apart and get there in completely different ways. Ghost Lap is an independent fan project that puts them side by side, so you can see where that difference comes from.
COMPARE LAPSWhere the data comes from
Lap times, sector times and telemetry come from Formula 1's timing feeds, accessed through FastF1. FastF1 is the software used to work with those recordings, not the owner of the underlying data.
FastF1 project (opens in new tab)What Ghost Lap adds
Ghost Lap aligns the laps, compares the gaps and draws the cars on the track. Its visualisations and energy model are built for this site. The 2D layouts and racing lines are simplified, not a record of each driver's exact path.
What to keep in mind
Telemetry is sampled, so not every change between readings is captured. Missing or reconstructed readings are marked. Energy and battery figures are estimates, not measurements from the cars.
Keeping it free
The comparison tool is free. If you find it useful, you can support Ghost Lap on Ko-fi. Contributions are optional and do not unlock data, priority access or extra features.
