A vehicle four-wheel drive system (10) comprises a first axle (12) with two coaxial first axle shafts (12, 12b) carrying two first wheels (13a, 13b) and a second axle (14) with two coaxial second axle shafts (14a, 14b) carrying two second wheels (15, 15b). A first one (12a) of the first axle shafts is directly driven by a first electric motor (16a) via a first gearbox (16b) and, similarly, a first one (14b) of the second axle shafts is directly driven by a second electric motor (17a) via a second gearbox (17b). A first belt-and-pulley drive transmission (18, 20, 21) drives the second one (14a) of the second axle shafts from the first one of the first axle shafts and a second such transmission (19, 20, 21) drives the second one (12b) of the first axle shafts from the first one of the second axle shafts. The wheels (13a, 15b) of the directly driven axle shafts are disposed on one diagonal and the wheels (13b, 15a) of the indirectly driven axle shafts on a second diagonal of the system.
