What suspension does the Infiniti QX50 use?
2 Answers
The Infiniti QX50 uses a MacPherson independent suspension at the front and a multi-link independent suspension at the rear. There are two common types of suspensions in cars: one is independent suspension, and the other is non-independent suspension. In an independent suspension, there is no connection between the two wheels on the same axle, so there is no interference in movement between them. The new Infiniti QX50 measures 4693mm in length, 1903mm in width, and 1679mm in height, with a wheelbase of 2800mm. Compared to the current domestic version, the wheelbase is 80mm shorter, while the width and height have increased. It is equipped with a new 2.0T variable compression ratio engine and is paired with a CVT transmission.
I've repaired the Infiniti QX50 many times. Its front suspension uses a MacPherson independent structure, while the rear suspension is a multi-link independent system. This suspension design is very mature, specifically tuned for daily driving, with excellent road vibration absorption, making the ride smooth and quiet. The advantage of the front MacPherson lies in its compact space, suitable for engine compartment layout, and it helps reduce vehicle weight. The rear multi-link provides better stability, especially during cornering and high-speed driving, with minimal body sway. The springs and shock absorbers are well-integrated, reducing bumps on rough roads and minimizing fatigue during long drives. However, it's important to regularly check the wear on bushings and ball joints, as older vehicles are prone to noise issues. Overall, this suspension combination is mainstream among luxury SUVs, reliable and durable, with maintenance that isn't too troublesome.
