• the rest of the vehicle is similar to the first embodiment described in connection with Figure 1, in particular the arrangement of the front seats and the pedal.
• the cabin receives only the two front seats and the absent rear seat allows to have a large rear cargo volume.
• the rest of the vehicle is similar to the first embodiment described in connection with Figure 1, in particular the arrangement of the front seats and the pedal.
