Cybertruck does not have a Unibody
The host of Design Prototype Test has a video where he brings up CAD and explains why you cannot call what Tesla does with the Cybertruck a Unibody. Maybe the car industry has a specific definition of an exoskeleton, but in terms of what exoskeleton means in general, I think Tesla is using the word correctly. It implies all the strength and protection is in the most exterior parts. Look at the video and see what you think.
