Final drivers' standings

A driver with points and no position was excluded from the classification: the points stand, the position does not. Wins are counted from the race records, and a shared drive is a win for both of its drivers. The gap is to the highest points total classified, so the leader's own is an em dash; before 1991 it is a difference of net totals, dropped scores and all.

The gap is to the highest points total classified, so the leader's own is an em dash; before 1991 it is a difference of net totals, dropped scores and all. The championship is contested by a chassis–engine pair, so one name can appear more than once with different engines.

Where an entrant ran more than one design, no source records which car raced which round — so those race results carry no chassis.

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.
