1. An energy absorbing and distributed side impact system for a vehicle, the system comprising: first and second side sills, each of the first and second side sills comprising multiple longitudinal channels, at least an upper longitudinal channel positioned above a vehicle floor panel and at least a lower longitudinal channel positioned below the vehicle floor panel;a battery enclosure mounted between front and rear suspensions of the vehicle, the battery enclosure having a first side member attached to the first side sill, a second side member attached to the second side sill, a plurality of cross-members integrated into the battery enclosure and extending between the first side member and the second side member, a top panel, and a bottom panel, wherein the battery enclosure encloses a plurality of batteries with all portions of the plurality of batteries residing below the vehicle floor panel; anda bolt extending through a first opening in one of the plurality of cross-members, a second opening in the vehicle floor panel, and a nut, and extending to an opposite side of the vehicle floor panel from the one of the plurality of cross-members. 2. The energy absorbing and distributing side impact system of claim 1, wherein the battery enclosure is an aerodynamic device having a design that improves aerodynamic performance of the vehicle. 3. The energy absorbing and distributing side impact system of claim 2, wherein a bottom of the battery enclosure is substantially flat. 4. The energy absorbing and distributing side impact system of claim 2, wherein front wheel arch edges on the battery enclosure are radiused to allow air from a front wheel to transition to an underside of the vehicle. 5. The energy absorbing and distributing side impact system of claim 1, further comprising a gasket material that covers a gap formed between a top of the battery enclosure and an underside of the vehicle floor panel. 6. The energy absorbing and distributing side impact system of claim 1, further comprising a seat mounting structure on the opposite side of the vehicle floor panel from the one of the plurality of cross-members, wherein the seat mounting structure is coupled to the one of the plurality of cross-members by the bolt and the nut. 7. The energy absorbing and distributing side impact system of claim 6, wherein the seat mounting structure further comprises at least one threaded seat mount. 8. The energy absorbing and distributing side impact system of claim 1, further comprising a sub-frame mount integrated into the battery enclosure. 9.

The energy absorbing and distributing side impact system of claim 1, wherein the battery enclosure is an integral part of a load path for managing loads in frontal impact. 11. The energy absorbing and distributing side impact system of claim 10, configured so that a majority of the loads are fed from rails at a front of the vehicle into a torque box. 12. The energy absorbing and distributing side impact system of claim 11, further comprising a secondary load path that feeds loads from a lower portion of the vehicle along a sub-frame and into a rear mount of the sub-frame coupled to the battery enclosure and to the torque box. 13. The energy absorbing and distributing side impact system of claim 11, wherein the battery enclosure is configured to feed the loads along its members to the first and second side sills. 14. The energy absorbing and distributing side impact system of claim 1, wherein a bottom plate of the battery enclosure is configured to provide shear stiffness to mounting locations of a steering rack. 15. The energy absorbing and distributing side impact system of claim 1, wherein the first side member is attached to the lower longitudinal channel of the first side sill and the second side member is attached to the lower longitudinal channel of the second side sill. 16. The energy absorbing and distributing side impact system of claim 1, wherein the one of the plurality of cross-members comprise an upper portion and a lower portion, wherein a spacing between the upper and lower portions is configured to receive a mounting bracket for at least one battery module in the battery enclosure. 17. The energy absorbing and distributing side impact system of claim 1, wherein each of the first and second side members comprises at least first through fourth lumens, wherein at least the first, second and third lumens are arranged in an essentially vertical configuration, and wherein at least the fourth lumen is arranged outward of the third lumen. 18. The energy absorbing and distributing side impact system of claim 1, wherein the plurality of cross-members segregate the battery enclosure into full-width sections and at least one other section, each of the full-width sections fitting two battery modules side-by-side in a direction of travel, the other section fitting two stacked modules. 19. The energy absorbing and distributing side impact system of claim 1, wherein the bolt further extends through a sleeve in the one of the plurality of cross-members. 20. The energy absorbing and distributing side impact system of claim 1, wherein the battery enclosure is coupled to a torque box.
