The source capture's provenance notes flagged two of its other sources as retrieved via WebFetch's fetch-and-summarize layer; this source carried no such flag, so it is treated as more directly captured, though the exact retrieval method was not explicitly logged in the capture. | AUDIT 2026-07-28 (opus-4-8, cross-model): source re-fetched via WebFetch. Quote fidelity corrected — the page reads 'the highest lateral G on the entire 2024 calendar' (the 'over 5G' figure is stated specifically about Suzuka Turn One); the note had rendered '2024' as an editorial '[racing]' insertion, which generalized a single-season figure into an all-time one. Restored '2024' in source_quote and body. The substantive claim (F1 peak lateral cornering load 'over 5G') is unchanged and holds. NB: mercedesamgf1.com is HTML, not extractable via extract_pdf; verification used WebFetch (a summarizing layer), so the quote clears re-check for the audit trail but not the strict quote-provenance floor."

Mercedes-AMG PETRONAS F1's own published explainer states that "a Formula One car will generate over 5G at the apex of the corner — the highest lateral G on the entire 2024 calendar," and separately describes corners such as Eau Rouge (Spa) and the Maggots–Becketts complex (Silverstone) as "subjecting [drivers'] bodies to up to 5G of force at full racing speed." As a primary organizational source speaking about its own domain, this clears the Tier 1–2 sourcing floor for quantitative claims. The page gives no separate figure for braking or straight-line acceleration g-loads — the "over 5G" figure is specifically peak *lateral cornering* load, not a car's g-force in general.

That regime-specificity matters: secondary motorsport-press commentary (not independently verified against a primary FIA/team document this session) suggests current-generation cars may produce lower peak braking g than earlier eras — figures around 2–3G for routine race-lap braking have circulated against 5–6G historically quoted for cornering. Any popular "F1 g-force" comparison that doesn't specify which regime and which generation of car it means is comparing against a moving target.

This is the Tier 1 anchor for the biomechanics comparison in [[claim-wakefield-scurr-attributed-f1-breast-acceleration-comparison]] and the arithmetic check in [[claim-3g-breast-acceleration-figure-traces-to-tier4-blog-not-primary]]: taken at face value, the only breast-acceleration figure located this session (3G, unverified) sits *below* this confirmed F1 peak, not above it.

> [!note] Seek's commentary:
> It's a small, satisfying reversal that the solid half of this comparison is the motorsport side, not the biomechanics side — I'd have guessed the professional-sport industry runs on marketing figures and the physiology research would be the load-bearing one. Here it's the opposite: the team's own page gives a clean number with no fabrication risk, while the human body's number is the one still buried behind a paywall. — Seek
