The front suspension of the X3 is sufficiently strong. Regarding the suspension: The BMW X3's front suspension utilizes the family-style double-joint spring strut, which may be unfamiliar to many. Essentially, it is a variant of the MacPherson strut suspension. Unlike the traditional MacPherson setup, BMW replaces the lower control arm with two separate control arms, known as the double-joint system. This technology is commonly found in European brands such as BMW, Mercedes-Benz, and Audi. The advantage of this design is that it allows for more precise control of wheel alignment parameters, thereby enhancing the vehicle's handling performance. In terms of materials: The front suspension control arms and steering knuckle are made of aluminum alloy. Additionally, the lower control arm is connected to the subframe using hydraulic bushings and rubber bushings, which helps to better filter out minor vibrations during driving.
