Vehicle monocoque body assembly

A vehicle self-supporting monocoque body assembly, comprising:

• a base frame structure including a bottom and easy-opening top surfaces and two opposite side surfaces on sides of the structure and two opposite front and rear surfaces on front and rear sides of the structure;
• a pair of front and rear wheel axles interfaces located at generally front and rear locations of the base frame structure for receiving a pair of front and rear wheel axles extending beyond the opposite side surfaces;
• an energy storage element compartment and interface positioned within the base frame structure, between front and rear wheel axles interfaces, for completely housing an energy storage element within the base frame structure;
• an engine compartment and interface positioned within the base frame structure, for completely housing an engine system within the base frame structure;
• a vehicle outer frame interface for supporting a vehicle outer frame;
• and
• front and rear suspension arm interfaces for interfacing with two pairs of front and rear symmetrical suspension arms extending along a length of the base frame structure between the suspension arm interfaces and the wheel axles, said suspension arms being parallel to the structure,
• wherein the bottom surface of the frame structure is positioned at or below a horizontal plane between center axes of the wheel axles.
