Battery size is an interesting topic. I have been trying to guess if Lucid will use the same size batteries as the Air (118DE, 112GT, 92AT) or try to increase. They cannot add more cells in series without increasing voltage over 924 volts. It is possible but 1000V chargers have substantially lower voltage after losses through the dispenser and cable to the car. The inverters/wunderbox also need to withstand the battery voltage. Hence, there is not much room to increase maximum battery voltage. One additional module would add 42V. I am thinking Lucid is unlikely to increase voltage.
The parallel strings of battery cells are limited by the module width which is limited by the width of the car. If Gravity is the same width as Air, then the number of parallel strings cannot increase either. If Gravity is wider than Air, then another string of cells in parallel is possible. The Air modules use 10 groups of 3 cells in parallel or 30 strings of cells in parallel. It may be possible to add another group of three to increase battery size to 33 stings in parallel or an overall increase 10%. Lucid gains a lot of manufacturing efficiency if they re-use the Air modules. Again, I am thinking that Gravity is about the same width as Air and therefore will reuse the same modules.
That leaves battery chemistry as an option. Given that Lucid's history is batteries for Formula-E, I doubt there is much increase to be had.
My conclusion is the battery size will be very close to Air. I am guessing that there are further improvements to the drive units, wheels and brakes that improve efficiency so the same size battery gives good overall range in the larger SUV. We will see tomorrow how wrong I am.
