Lucid Confirms First Customer Deliveries to Take Place on October 30

Kind of an esoteric question, but I'm curious:

Per the press release, the Dream Edition has a 118kWh battery packs with 22 modules and the GT has a 112kWh battery pack. Each Dream Edition battery pack was 6600 2170 cells made by Samsung SDI, whereas the GT battery packs are supposed to be made from LG Chem cells.

Does this mean that the Dream Edition Samsung SDI cells have a higher wattage than the LG Chem cells? If they both have the same number of cells, a Samsung SDI cell should have 17.9Wh or 4800mAh of storage (assuming 3.7V) and an LG Chem should have 17Wh, or 4600 mAh at 3.7V.

It's too bad Lucid didn't go with Samsung across the board, as it could have the same battery capacity with 21 instead of 22 modules, leading to decreased curb weight and increased performance. And maybe a little more foot room in the back.

I'm wondering how much of the difference in the capacities of the two battery packs has to do the storage capacity of the cells or whether the chemistry of the Samsung cells is more tolerant of full charging, thus enabling Lucid to reduce the upper-end buffer of the pack. In press releases at the time Lucid announced its partnership with Samsung, they specifically mentioned charging tolerance as one of the aims of the proprietary chemistry they developed with Samsung. No similar mention was made in the later announcement concerning LG Chem cells.

On a different note, I notice that the weights of the cars are identical across the Dream P / Dream R / Grand Touring line-up at each wheel size, and that the step up to 21" wheels adds 33 pounds to each model. The 21" wheel on the Dream Edition is the only wheel shown on Lucid's website as being forged. Usually a forged wheel is considerably lighter for a given size. Does this mean the Grand Touring 21" wheel is also forged, or the spoke design of the Dream Edition 21" wheel requires more material than the 21" Grand Touring wheel?
