Does simply skinning the car in CF really make it better/stronger/safer? The properties of CF are not the same as steel or aluminium. While CF is no doubt lighter, it doesn't seem likely they you can just interchange the two. I would think a good CF chassis would actually be designed differently.

To my knowledge it is more than simply re-skinning in carbon fiber - I think you can see the carbon tub in the transparent  graphic.
