BRM

All figures refer to BRM in 1971, using this constructor’s Jolpica ID. Team renames with a different ID are separate records. Podiums, starts, DNFs and averages count race entries, not weekends. A double podium counts twice. Pole starts use the final race grid, not qualifying classification. Non-starters and disqualifications are excluded from position averages and changes as appropriate; lapped finishes count as finishes. Official championship points may differ from the sum of driver race points because of sprint scoring, historical rules and penalties. Before the constructors’ championship existed, official standings and points may be unavailable. Positions Gained/Lost sums grid minus finish separately for each completed car start with valid positive positions, using only entries for this constructor in the selected season. Retirements, non-starters, disqualifications, unclassified results and pit-lane or unknown grids are excluded. A dash means no eligible entries; zero means no net change. The tooltip retains the previous calculation as Net Positions incl. DNFs. This is not an overtake count. Shared drives can produce multiple historical entries.
