    The fast DC chargers have a gross power from the grid and a net power into the battery. The problem is EA (and others?) report the grid power input which then is converted to DC with some loss of power from the electronics. In contrast, the Tesla SuperChargers report the power to the batteries. Tesla 'eats' or doesn't report their charger losses.

    Apparently some of the Lucid reviewers are using the gross, grid power to claim the battery is larger than manufacturer reported, battery kWh.

    How does one review a vehicle that doesn't exist

    They get a ‘press’ car that can not be sold. Often these cars wind up in other testing.

    Oops, it was meant rhetorical - as the finished product may not be exactly the same as the first article(s) - & giving the benefit of the doubt that they won't fold like other startups have

    Well, the EPA ratings are from the outlet, so include the loses of AC charging(I think Level 2). Need to include those losses with DC charging for like comparisons. Doesn't redeem ignorant reviewers though.

    The energy used by a Tesla for battery conditioning during charging, is that included in the to the battery amount, or reported separately?

    Edit: Lucid started delivering the Dream Edition a month ago.
