    摘要： 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°. A rear 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°.

    摘要： A rear sub frame comprising a pair of side members, a front cross member, and a rear cross member. The front cross member is configured in substantially a V shape in a front view such that the front cross member slants continuously from both end portions thereof toward a central portion, in a vehicle width direction, thereof which is located below a rear differential, and that a center position, in the vehicle width direction, of a bottom portion of the front cross member which corresponds to an apex portion of the V shape is offset from a center of a vehicle body in the vehicle width direction toward a specified side which matches an offset-arrangement side of a ring gear arranged in the rear differential.
