The carbodies have four structural tubes that run the length of the car, end sheet to end sheet with 'buffers' on the ends to allow the carbodies to interface with each other in a collision. All of these members are on the corners of the shell, one pair is just above the doors, the other pair is just below the doors. These tubes are part of the crash worthiness structure, they keep the shells in shape in the event of a collision to a much greater extent than a standard center sill design. You would have to cut these members to add traps/wells for low level platform access. It's a compromise but one that's needed if you want to have added carbody structural performance. |
