A motor vehicle comprising: a steer control apparatus to steer a steerable wheel (17FL, 17FR) by actuating an actuator in accordance with a steering condition of a steering wheel; and a suspension apparatus to support the steerable wheel to a vehicle body with a wheel hub mechanism to support a tire wheel (17FL, 17FR) to be provided with a tire; characterized in that the suspension apparatus comprises: a first link member (37; 137; 237; 337; 437) connecting the wheel hub mechanism and the vehicle body on a lower side of an axle in an vehicle up and down direction; and a second link member (38; 138; 238; 338; 438) connecting the wheel hub mechanism and the vehicle body on the lower side of the axle in the vehicle up and down direction and intersecting the first link member in a vehicle top view; in that a kingpin axis passing through an upper pivot point of the suspension apparatus and a lower pivot point located at an intersection point of the first link member and the second link member is set to pass through a tire ground contact surface at a neutral position of the steering wheel; in that the steer control apparatus is configured to steer the steerable wheel by producing a restoring force for self-aligning in the steerable wheel by actuating the actuator and thereby to secure a straightness of the vehicle; in that the steer control apparatus comprises a straightness securing section (SG, 63) to secure a straightness of the suspension apparatus, and a steer response setting section (SRS, 56) to set an early steer response characteristic at a steer response characteristic of the suspension apparatus by adjusting a straightness securing control of the straightness securing section when a steering operation of turning the steering wheel is started from a neutral position of the steering wheel. a steer control apparatus to steer a steerable wheel (17FL, 17FR) by actuating an actuator in accordance with a steering condition of a steering wheel; and a suspension apparatus to support the steerable wheel to a vehicle body with a wheel hub mechanism to support a tire wheel (17FL, 17FR) to be provided with a tire; a first link member (37; 137; 237; 337; 437) connecting the wheel hub mechanism and the vehicle body on a lower side of an axle in an vehicle up and down direction; and a second link member (38; 138; 238; 338; 438) connecting the wheel hub mechanism and the vehicle body on the lower side of the axle in the vehicle up and down direction and intersecting the first link member in a vehicle top view; in that a kingpin axis passing through an upper pivot point of the suspension apparatus and a lower pivot point located at an intersection point of the first link member and the second link member is set to pass through a tire ground contact surface at a neutral position of the steering wheel; in that the steer control apparatus is configured to steer the steerable wheel by producing a restoring force for self-aligning in the steerable wheel by actuating the actuator and thereby to secure a straightness of the vehicle; in that the steer control apparatus comprises a straightness securing section (SG, 63) to secure a straightness of the suspension apparatus, and a steer response setting section (SRS, 56) to set an early steer response characteristic at a steer response characteristic of the suspension apparatus by adjusting a straightness securing control of the straightness securing section when a steering operation of turning the steering wheel is started from a neutral position of the steering wheel.
