The lower transverse beam serves as the bearing element of the front suspension. The power unit is attached to the beam through appropriate supports.
The front suspension is McPherson type independent. The aluminum alloy upper arms are attached to the body through rubber bushings, and to the steering knuckle through ball joints. Lower (holding and managing) the levers are connected through rubber bushings to the lower frame, and to the steering knuckle through ball joints.
The elastic element of the front suspension is made in the form of a rack with additional elastic polyurethane elements and suspension travel limiters with a progressive characteristic. The upper part of the shock absorber strut is attached to the upper front suspension bracket, and the lower part is attached to the transverse arm.
