Abstract: A motor-vehicle, comprising a first and a second wheel, a third and a fourth wheel, a first and a second reversible electric machine connected to the first and second wheel; a third and a fourth reversible electric machine connected to the third and fourth wheel; and a rechargeable electrical power source; a control unit programmed to: process electrical power values available for the regenerative engine brake simulation based on the amount of electrical power still storable in the source and on first operating parameters of the motor vehicle; communicate said available power values to the respective first, second, third and fourth electric machine and receive, from them, values of a first, second, third and fourth torque available for the regenerative engine brake simulation associated with second parameters of the electric machines; and cause the first, second, third and fourth electric machine to implement a respective first, second, third and fourth braking torque acting upon the respective wheels.

Abstract: A fuel supply system for a road vehicle and having: a fuel tank, which is shaped like saddle due to the presence of a central saddle and delimits an inner volume divided into an upper area, which is located above the central saddle, and two lower areas, which are located under the upper area and are separated from one another by the central saddle; two low-pressure fuel pumps, which each suck from the bottom of a corresponding lower area; at least one high-pressure fuel pump, which receives fuel from both low-pressure fuel pumps; a level sensor arranged in the upper area and configured to measure a fuel level only in the upper area; and two level sensors, each arranged in a respective lower area and configured to measure a fuel level only in the respective lower area.
