This time it's something structural. In previous renderings, Carbon Fiber Sheet Molded Compound parts have been depicted in dark gray while Fiberglass SMC has been shown as light gray. If that's still the case, this image shows some of Aptera's internal CFSMC structural components and some of the outer body SMC panels - the body side panel in particular. It also shows the front and rear suspension components attached to the structural aluminum frame of the battery pack (which serves as Aptera's chassis). Missing (among other things...) is the curved aluminum belly panel that serves as Aptera's passive radiator.
