Not on unibody cars. There isn’t a big increase in frame area in this car versus any other unibody out there. The difference here is the unibody isn’t actually a unibody, it’s a multipart unibody that is bolted together. A standard unibody, which is just about everything on the road today that isn’t a pickup truck, is all three of those frame pieces you see in that picuture, but as one giant piece. That big piece of metal you are normally used to seeing in car assembly photos. There are no frame rails under it. The unibody being split into segments is the first real change to the unibody design since GM started using it in the 80’s.
