I am 90% sure that it is not a tub. What I see in the photo is a 'sandwich' chassis. This is very common when working with any composit materal. There are 2 layers of materal, in this case carbon fiber, seperated by a filler, here a foam I am sure. In aerospace, where I work, we use differentmaterals from poltstirene to a honeycomb to a lattace frame. What happens is that when you seperate the layers of materal you vastley increase their torsional ridigity. This process was auctualy pioneered by my father in the 40's and 50's.
Here is a carbon pannel with a aluminum honeycomb core..
My money is that this is what he is useing..
This is a foam core. Looking at the sides of the model I see no honeycomb structure. It looks solid. I have used foam core carbon pannels extensively and I am fairly sure that this is what he has used. I would.
This would produce a chassis as stiff as iron but a a huge weight savings.
