Resolution criteria

• Resolve YES if, for September 2025 U.S. light‑duty vehicle sales reported by Argonne, the quantity M = ICE + 1.075×HEV + 1.12×PHEV strictly exceeds 1,291,000; otherwise NO.

  Resolution criteria

  • Resolve YES if, for September 2025 U.S. light‑duty vehicle sales reported by Argonne, M = ICE + 1.075×HEV + 1.12×PHEV strictly exceeds 1,198,000; otherwise NO. (anl.gov)

  • Use Argonne’s September 2025 monthly update as the source of HEV, PHEV, BEV, and total LDV sales. If Argonne does not list ICE explicitly, compute ICE = Total LDV − (HEV + PHEV + BEV). Do not round intermediate values; compare using the exact arithmetic result. (anl.gov)

  • Definitions: HEV = hybrid electric (non‑plug‑in); PHEV = plug‑in hybrid; BEV = battery‑electric; Total LDV = U.S. light‑duty vehicles ≤10,000 lb GVWR, per Argonne. If Argonne revises September 2025 figures within 14 days of first publication, use the latest revision available at resolution time. (anl.gov)

  Background

  • Argonne’s monthly update is the standard reference for U.S. HEV/PHEV/BEV sales and LDV totals (sourced from Wards). Example recent scale: June 2025 had 153,660 HEVs and 19,716 PHEVs; PEVs captured 9.0% of LDV sales. (anl.gov)

  • For context on total market size, August 2024 LDV sales were 1,418,771 (as cited by the U.S. Joint Office from Argonne). BEVs don’t enter M directly but reduce ICE via Total LDV − (HEV + PHEV + BEV). (driveelectric.gov)

  Considerations

  • Argonne occasionally revises recent months; this market follows Argonne’s definitions and the latest September 2025 values available at resolution. (anl.gov)

  • Argonne’s EV dashboard exists but access can vary; the public “Light‑Duty Electric Drive Vehicles Monthly Sales Updates” page will be the authoritative source for this market. (anl.gov, evdashboard.esia.anl.gov)
