If you look at the arch coming down from the roof, it flows down to the edge of the wheel wells crease. This may be some sort of code breaking design technique for the genesis of auto design or something.
Sphere - set to Roof Height
Toroid (ring, doughnut, or Wheel Wells looking from the side as a cutaway)- are the Wheel Wells - are to be on the inside of sphere with the parameter lines over lapping or at zero point of each other
This image is to show you what a toroid looks like:

Now cut the sides and bottom of the unused(just at the zero point of the Toroid) portion of the sphere to make it look more like a vehicles frame (I call the unibody [built like a shark] cartilage and the front and rear suspension or chassis the bones). You can make the vehicle flatter by keeping the wheel base and increasing the size of the Sphere. The Toroid should move up for a flatter look and down for a more rounded look as you increase and decrease the diameter of the sphere.
Experiment with the parameters the of sphere placing the parameter of sphere through the center axis the wheel wells and having the Toroid (ring or Wheel Wells looking from the side as a cutaway wire frame or mesh) on the outside of sphere also with the parameter lines over lapping or at zero point of each other. The side glass widows should end at the spheres arch line. I think I know why they are calling it the FIT Platform, because they are trying to fit most of the car in between the wheel wells and under the arch of the sphere. This should help to make it safer in crashes and to balance the cars center of gravity. This has NOTHING TO DO WITH EMOTION that's DEMON STUFF. It is measuring and weighing logical placements or factors. Like wind resistance and crash testing. Some crash test sites have see through floors to see what happens under a vehicle as it is tested and the observation post (where camera monitors are) is placed above the floor. The reason nature looks nice is because it shapes its self according to design factors, it is ROBOTIC. Like plants, they move toward sunlight and grow in it. They are programmed do this. This is how I interpret it.
After the Wheel base (distance between wheels) is set and ever thing is balanced inside of the rolling chassis they probably just added the sides, front, and back. Maybe someone can make a model using this process and post it on the forum.
Maybe you can use a cylinder 3D brush to help make the vehicle more rounded instead of clipping off the sides and bottom. Anchor the cylinder to the zero point edge of the roof top (sphere) and wheel wells outer most set diameter and clip excess portion.
Or maybe Oldsmobile, a I mean Saturn can try building a car like the 8th Gen Honda Civic. They need some good car designs
Honda Small Hybrid Sports Concept - LOOK AT THE DOME LIKE ARCH - wheel well to wheel well - well, not really, it looks like it does from this angle though

Tron Lightcycles - this design reminds me of the Sphere-Toriod design

Arranque Nuevo Honda Civic - nice use of space by adding instrumentation above the center axis of the speedometer

1 Vertical Door Levers design- like the ones on the Honda Civic Type R
2 All around shape
3 Grill and Head Lamps design - The absence of having the body separate the grill from the head lamps (not all 8th Gen variations are like this, but I did see the Si with this configuration)- it looks like the grill and head lamps are sitting in an air vent of a super charger - Nissan did something like this with it's 2001 350Z vertical signal lights
4 Dashboard with digital instrument cluster
5 The way the window shield looks like it's slopping down under the edge of the hood. To me it's a take it or leave it
