The original design was that the body would be made from these panels. The exoskeleton structure.
replyThe Cybertruck that was released did not have that, instead the panels are just normal body parts connected to a standard car frame underneath - like any other car.
Most cars use a unibody design and there's no frame underneath it all. The body is the frame.
replyMost pick up trucks are body-on-frame style.
The Cybertruck is a hybrid. There is an aluminum frame for the tow hitch and battery pack, but the body panels are also structural (unibody).
