As far as I know, the only really significant unique components of the Dream were the exotic metallurgy in the rear motor, the Samsung battery pack (which Lucid is continuing to use), and the forged 21" wheels (which are vendor-supplied). The rest of the chassis, from brakes to suspension, was common to the GT, as were all the software, screens, and control interfaces. The interior trim differences were really in colors, not materials. Cost differences on that score would have been attributable only to buying in reduced quantities and the minor added costs of production line management of a limited run. In fact, if the Gravity Dream is just a unique trim upgrade, Lucid will still be saddled with the expense of special trim for a limited-volume run, anyway.
