    Here is what is reported on the EPA's detailed 2024 Datafile. No for Prius Prime, yes for RAV4 Prime and NX 450h.

    I seem to remember conflicting answers elsewhere on the RAV4, one indicating both wheel sets, the other indicating front only, and haven't looked or checked further to resolve the conflict.

    The data is conflicting.

    According to the DoE/EPA documents:

    MY 2023
    Prius HEV FWD - Both front and rear
    Prius HEV AWD - Both front and rear
    Prius Prime PHEV FWD - Front only

    MY 2024
    Prius HEV FWD - regen data not filled out
    Prius HEV AWD - regen data not filled out
    Prius Prime PHEV FWD - Front only

    MY 2025
    No Priuses added yet


    I can understand the PHEV having front only and the AWD HEV having both front and rear, but how can the FWD HEV also have both front and rear? I don't know how much to trust the data.
