A dual level, vibration isolation system is provided that isolates a vehicle in general, and the vehicle's passenger cabin in particular, from the vibrations generated by the vehicle's motor during normal operation. The first isolation level uses a first plurality of isolation bushings to mount the motor assembly to a first portion of the battery pack. The second isolation level uses a second plurality of isolation bushings to mount the first portion of the battery pack directly to the vehicle. In addition to providing two levels of vibration isolation, this compliant mounting scheme allows the mass of the battery pack to absorb and damp out undesirable rotational oscillations caused by the motor, especially when the motor is undergoing strong acceleration or deceleration.
