Vehicle drive system

A vehicle drive system includes : a front drive unit (U1) in a front part of a vehicle, which has an engine (1) and a torque converter (2) integrally assembled to one another; a rear drive unit (U2) in a rear part of the vehicle, which has a transmission (3) and a differential (4) integrally assembled to one another; and a drive shaft (5) connecting the torque converter (2) of the front drive unit (U1) and the transmission (3) of the rear drive unit (U2). The drive shaft (5) is configured to be elastically twistable for damping vibration transmission between the front and rear drive units (U1,U2). The drive shaft (5) may be made of fiber-reinforced plastics material.
