I'm using a couple hints that Elon dropped on the project to come up with what I think will be the interior layout of the Spacebus: - It will use the same chassis as Model X - It will be able to carry people on wheelchairs - It will do away with the center aisle regularly present in buses I used the following picture of the Model X from the top-down to try and come up with a model: Based on this, I used excel to create a super-simple and incredibly unscientific breakdown of the space inside the chassis: The yellow spaces are my rough estimation of the space taken up by each seat in the car. The grey spaces are regions of the car that are primarily used for cargo or house some sort of control for the car (i.e. dash, pedals, etc.) Any white spaces are buffer zones that are inherently present in the vehicle so that there's adequate room between the objects. Keep in mind that the graphic above does NOT include the frunk. The black bar in the chair is the orientation of the human in the chair. Using the same exact boundaries, I went ahead and took one of the larger monopost seats in the second row (the one with the black bar) and rearranged the inside to try and maximize people to space ratio while meeting the criteria that Elon outlined. The result is the following: Observations: -Model X is theoretically able to hold 10 humans if they are facing to the side and the seat is of the same size as the larger second-row monopost seat. - One of the rows can be left without a seat so that someone with a wheelchair can literally wheel right in with the assistance of a retracting ramp. - The middle area of the chassis (in grey) can be used as a cargo area for people, as well as underneath the seat since it's a monopost design This points me towards the following conclusions: - Elon had a plan with the falcon wing doors and the monopost seats from the beginning. He was envisioning using both things to create this form of bus that allows people to hold their carry-ons underneath and behind their seats. - The spacebus will have 10 individual falcon-wing doors, which will open/close depending on the seats that are being vacated/populated on each destination stop. Thoughts?
