Q: Do the carbon doors keep the factory side impact beams?

They keep that protection, but reproduce it in carbon. Rather than deleting the side impact structure to save weight, we reproduced the factory side impact beam design in full dry carbon and added carbon inner reinforcement beams in each door. Combined with the steel sandwiched into the skin, that preserves the crash structure’s intent while still cutting mass. It is the harder, more expensive way to build a lightweight door, and it is the one we chose.
