The front wheel suspension has a track width of 1571 millimeters (61.85 in) and follows a classic design. It is a McPherson strut construction with lower wishbones of forged aluminum. The subframe to which they are mounted is made of a chill-cast lightweight alloy, which has a favorable effect on the distribution of weight between the front and rear axles. This figure is roughly 58 to 42 percent. The subframe is rigidly bolted to the body, which further enhances its rigidity. The four-link rear axle of the Audi Q3 has a track width of 1575 millimeters (62.01 in). Its trailing links absorb the propulsive and braking forces. Its bearings are rather large for a more comfortable ride. On the other hand, the three wishbones per wheel are attached very rigidly to the steel subframe for optimum handling characteristics. Large rubber-metal bearings connect the subframe to the body.
