Vehicle suspension system

A vehicle suspension system comprising:

• a front suspension that suspends a front wheel;
• and
• a rear suspension that suspends a rear wheel, wherein
• the front wheel and the front suspension are configured such that
• a caster angle defined by one of a kingpin axis and a virtual kingpin axis falls within a range of +3 degrees to +5 degrees in a side view,
• a caster trail defined by a center of a tire contact patch and one of the kingpin axis and the virtual kingpin axis falls within a range of +20 to +30 mm in the side view,
• an intersection point between a ground and an extension line of the kingpin axis or the virtual kingpin axis is located on an inner side in a vehicle width direction of the center of a tire contact patch in a front view, and
• a lower arm coupling a vehicle body and a wheel support member is provided, and an anhedral angle of the lower arm falls within a range of +2.8 degrees to +7.2 degrees in the front view further based on a vehicle weight on the front suspension, and
• the rear suspension includes five links that couple the vehicle body and a wheel support member, and the rear suspension and the rear wheel are configured such that a virtual kingpin axis extends near the center of a tire contact patch of the rear wheel and extends vertically at an angle within a range of −2 degrees to 0 degrees.
