Light weight passenger vehicle with expandable body size for collision protection

A method of constructing a light-weighted motorized passenger vehicle comprising the steps of:

• constructing a chassis having a central vehicle frame with a least a door opening in each side thereof;
• attaching securely a rigid front section to front portion of said central vehicle frame;
• attaching securely a rigid rear section to rear portion of said central vehicle frame;
• constructing a expandable-retractable body assembly enclosing said rigid front section, said rigid rear section and further enclosing non-glass, lower portion of said chassis;
• and
• installing an integral vehicle body size control device for integrally linking and controlling said expandable-retractable body assembly, whereby said expandable-retractable body assembly of said light-weighted motorized passenger vehicle is expandable to a predetermined expanded size for gaining extra collision protection and retractable to a predetermined retracted size for easier handling in narrow alley in vehicle moving and standing conditions under a plurality of different driving environments.

A light-weighted powered passenger car having an expandable and retractable car body comprising:

• a main vehicle assembly having a central vehicle frame which includes a least a door opening in each side of said central vehicle frame, said main vehicle assembly further comprising a vehicle wheel system, a vehicle steering system, a vehicle seating structure, a vehicle power system and an instrumentation system for manipulating said motorized passenger vehicle in a predetermined speed range and a predetermined load, and for monitoring performance of said motorized passenger vehicle;
• a rigid front section securely fixed to front portion of said central vehicle frame;
• a rigid rear section securely fixed to rear portion of said central vehicle frame;
• a front expandable-retractable body assembly securely attached to said rigid front section and capable of expanding forward and sideward to a predetermined expanded size and capable of retracting backward and sideward to a predetermined retracted size;
• a side expandable-retractable body assembly for each side of said main vehicle assembly, securely attached to each side of said central vehicle frame and capable of expanding to a predetermined expanded size and retracting to a predetermined retracted size;
• a rear expandable-retractable body assembly securely attached to said rigid rear section and capable of expanding backward and sideward to a predetermined expanded size and retracting forward and sideward to a predetermined retracted size;
• and
• an integral vehicle body size control device for integrally linking and controlling said front expandable-retractable body assembly, said side expandable-retractable body assembly, said rear expandable-retractable body assembly and said instrumentation system, whereby said light-weighted powered passenger vehicle is expandable for gaining extra collision protection and retractable for narrow alley handling in vehicle moving and standing conditions under a plurality of different driving environments.
