Abstract: An electrically powered motor vehicle for transport of goods, of the minivan type, includes a main frame, a front axle assembly and a rear axle assembly. The main frame includes a front frame subassembly, a floor-panel subassembly, a rear frame subassembly, and a top frame subassembly. Each of these frame subassemblies includes a lattice structure including box-section elements made of steel, preferably high-strength steel. Each of the frame subassemblies is prearranged for being preassembled separately and subsequently assembled together with the other subassemblies so as to constitute the main frame. The structure is such as to afford high flexibility of production, and presents at the same time considerable safety characteristics, thanks to a high capacity of absorption of impact energy. The motor vehicle is equipped with a transporting body having a hollow-walled body made of plastic material, filled with foamed plastic material, preferably obtained with the rotational-molding technique.
