Cleanliness
A ledger of driver errors and sanctions across the race weekend, converted to a single cleanliness dial. Unlike the other scores this one starts from a flawless weekend — every mistake or penalty subtracts from it, so a spotless race sits at the top of the grade and each incident pulls it down.
This season, George Russell leads Cleanliness: 9.65 against the grid, across 11 rated races. The single best Cleanliness performance of the year belongs to Charles Leclerc — 10.0 at the MEL.
How the grid reads on Cleanliness in 2026
what the season table actually saysAt the top. George Russell leads Cleanliness on 9.65, 0.39 clear of Yuki Tsunoda on 9.25. 23 drivers have enough running to be rated, and the field runs from 9.65 down to 6.26 — a spread of 3.38 of a grade point.
The speciality. Isack Hadjar is P4 on Cleanliness but only P20 on The Index overall — 16 places better here than at everything else put together. On this one measure, this is what they are for.
The soft spot. Kimi Antonelli runs the other way: P2 on The Index but only P17 here, 15 places worse. A driver good enough to rank high overall is giving something back on cleanliness.
Same car, same measure. Team mates share machinery, so the gap between them is as close to a clean read as cleanliness gets. The tightest pair on the grid is Ferrari — Lewis Hamilton and Charles Leclerc separated by just 0.01. The widest is Mercedes, where George Russell is 1.81 ahead of Kimi Antonelli.
What this number is not. Cleanliness is one of nine independent measures, and a driver can lead it while sitting mid-table overall — the season grade in the last column is this metric alone, not a summary of the driver. It is also a rating against the rest of the grid this season, not against history: it says who is doing this best right now, not who has ever done it best.

A race grade rates one afternoon; a season grade rates a driver across the year against the rest of the grid. They answer different questions, so they are not versions of the same number and the season figure is not the row added up. – = not classified that race (insufficient running, or the situation made the metric unmeasurable — the driver is never penalised for it), and never counted towards the season; the championship still accumulates per-race points.
