A vehicle suspension system smoothly changes a vehicle posture with respect to a steering force and a steering angle by minimizing a kinematic roll at an initial turning stage, thereby allowing a driver to obtain the sensation of maneuvering the vehicle well. The suspension system includes a front suspension having geometry satisfying that a caster angle is +3° to +5°, a caster trail is +20 to +30 mm, an intersection point between a kingpin axis and ground is located on an inner side in a vehicle width direction of a center of a tire contact patch, and an anhedral angle of a lower arm is +2.8° to +7.2°. Arear suspension includes five links and has geometry satisfying that a virtual kingpin axis extends near the center of a tire contact patch of a rear wheel assembly and extends vertically at −2° to 0°.

A suspension assembly for a vehicle having a frame includes a control arm, knuckle, spring, damper, and control module. The control arm is pivotably coupled to the frame. The knuckle is coupled to the control arm and supports a wheel hub for rotation relative to the knuckle. The spring is mounted between the frame and the control arm or the knuckle. The damper has an adjustable damping force and includes a first end mounted to the frame and a second end mounted such that a change in caster angle of the knuckle extends or contracts the damper. The control module is in communication with the damper and configured to adjust a damping force of the damper based on an actual or predicted change in caster angle of the knuckle. The control module is configured to increase the damping force in a direction that resists a change in the caster angle.
