Grid to flag

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

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.

The cars in this race

The photograph each car's Wikipedia article leads with, from Wikimedia Commons: taken wherever and whenever that was, not necessarily at this race.

A photograph marked unchecked has a file name that does not name the car it is shown for. Most are still the right car, filed under the driver rather than the machine — but nobody has confirmed these one by one.
