How it is modelled

ERA5's reanalysis, through Open-Meteo, of the circuit's whole local day and not the race's hours, for the grid cell the circuit sits in and not the track, so a shower can be missing from it. Contains modified Copernicus Climate Change Service information 2026. Neither the European Commission nor ECMWF is responsible for any use that may be made of the Copernicus information or data it contains.

Lines run from grid slot to result, ending at the last lap completed. A dashed line ending in a cross is a driver not classified. Nothing between is recorded, so a crossing is not an overtake at that lap.

Before knock-out qualifying arrived in 2006 there is one time per driver; from 2006, the best lap of each of the three sessions.
How it is derived: distance, Qualifying

Distance at the session-best lap’s average speed, on the layout raced that year.

Pit stops

Pit stops are recorded from 1994. F1DB, the source of every stop here, holds none before then, so this race has no stints to draw.
