Temptation is to take everything down proportionately, given Lucid's "16" vs. "11" minutes to add 200mi (@1000v) and 89 vs 123 KWh both average a ~29-30% cut. It follows that non-Lucid/EPA tested ~360mi @70mph will only be nominally better, in Touring, than 256 highway. This is before cold and the normal ~3-5% degradation over the first couple years.
Maybe Touring's lower mass will test out at 3.3mi/KWh, vs. GGT's 3.1 (taking 70mph range to ~280), but my head's going the opposite way; the hammer of 170-205KWh in Ultium packs, to do the job while aiming to avoid lower 150KW Tesla SC rates (I saw full EA chargers, just today). For actual touring, year round in New England, grabbing ~225KW, for a ~260-280 mile Gravity doesn't compare to raw range. No, these aren't the same vehicle but EV range remains the biggest luxury, to me. That, or like many, wait for new GGTs to shed $$.
