An electric vehicle includes a chassis and a compartment defined by the chassis. A power container houses at least one energy storage/generating device for powering the electric vehicle. The power container is insertable into and removable from the compartment through the left side and the right side of the chassis. A suspension apparatus includes a shaft, a control arm pivotably connected to the shaft, at least one helical torsion spring mounted on the shaft, and a linear actuator. Movement of the linear actuator increases bending stress on the at least one helical torsion spring and urges the control arm downwardly.
