An ultra-light road vehicle such as a so-called 'town car', particularly an electrically powered one, wherein the weight of the basic construction is minimised so that the vehicle may be powered by batteries while having a standard degree of autonomy for the class of vehicles in question, and the space requirement of said vehicle is reduced for easier parking. For this purpose, said vehicle comprises a chassis (9) with a central hollow beam (12) consisting of an extruded profile section made of a lightweight material and forming a housing for batteries (52) and a driving engine (28), a body (8) consisting of a separate sealed hollow assembly mounted on the chassis, and two steerable wheels (17, 18) at the front and a drive wheel (15) at the back connected to the chassis via suspensions. The rear wheel (15) is mounted on pivotable arms (27) so that the vehicle can be converted from a normal position to a shortened position in which the wheel base is reduced. The pivotable arms (27) are substantially aligned with the central beam (12) when the vehicle is in the normal position, and at an angle thereto when the vehicle is in the shortened position.
