Formula 1 cars generate documented peak lateral g-forces of 'over 5G' at corner apexes, per the sport's own teams

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.
