<p>The invention relates in particular to an automobile (1) including electric traction means acting on at least two wheels (21, 22, 23, 24) of two different axles (2, 3), the electric traction means including an electric machine (43, 44, 45, 46) and a transmission (33, 34, 35, 36) defining a fixed transmission ratio between the rotation speed of the electric machine and the rotation speed of the wheel, a first transmission (35) for at least one of the wheels of the first axle (3) defining a first transmission ratio and a second transmission (33) for at least one of the wheels of a second axle (2) defining a second transmission ratio, the first transmission including coupling/decoupling means capable of assuming a coupling position in which the rotation of the electric machine is coupled to the rotation of the wheel and a decoupling position in which the rotation of the electric machine is decoupled from the rotation of the wheel, the first transmission being systematically decoupled beyond a decoupling speed (Vd), the second transmission being permanently coupled, the vehicle being capable of a maximum speed (Vmax), and the ratio between the maximum speed and the decoupling speed being higher than 1.6.</p> |
