The Great Wall C30 NEV uses a MacPherson independent suspension at the front and a torsion beam non-independent suspension at the rear. Below is an introduction to the MacPherson independent suspension and torsion beam non-independent suspension: 1. The most common non-independent suspension in cars is the torsion beam suspension. This type of suspension has a simple structure, small size, occupies little space, and is relatively low-cost. 2. Many compact cars and small cars use torsion beam suspensions. This is not only to reduce costs but also because many small and compact cars do not have enough space at the rear to install a multi-link independent suspension. Using a torsion beam suspension can also increase rear passenger space and trunk space. 3. The MacPherson suspension is the most widely used suspension, with a relatively simple structure. The MacPherson suspension has only one L-shaped control arm and hardly occupies any engine compartment space. Many cars with front-mounted transverse engines use MacPherson suspensions, which are also relatively low-cost.

Previously researched the chassis configuration of the Great Wall C30 EV, which uses a fairly common suspension setup. The front wheels feature a MacPherson strut independent suspension—simple in structure and space-efficient, making it practical for EVs since the chassis needs to accommodate battery packs. The rear wheels use a trailing arm torsion beam non-independent suspension, commonly known as a torsion beam. This design is cost-effective and durable, handling heavy loads without sagging noticeably. The ride feels firm, with slightly noticeable bumpiness in the rear over speed bumps, but the steering support is crisp. In fact, most EVs in the same price range adopt similar configurations—for example, the BAIC EC Series also uses a front MacPherson and rear torsion beam setup, which is sufficient and cheap to maintain.

Our family bought a used C30 electric version last year, and we drive it every day to pick up and drop off the kids. The suspension is just like that of a regular family sedan, with a MacPherson strut setup in the front that provides stable cornering, and a torsion beam structure in the rear that handles city concrete roads well, though it can feel a bit bumpy on occasional rural rough roads. However, the battery mounted on the chassis lowers the center of gravity, making lane changes on the highway more stable than the gasoline version. Once, I borrowed a friend's Emgrand EV in the same price range, and its suspension tuning was similar—both lean towards a practical approach. If you frequently drive on bumpy roads, it's advisable not to inflate the tire pressure too high, as it can help reduce some of the vibrations.

The repair shop has seen many C30 new energy accident vehicles. Its front suspension is a MacPherson strut with single-layer stamped components, and the lower control arm is not particularly robust but is cheap to repair, costing just over three hundred to replace. The rear torsion beam suspension is extremely simple, with two shock absorbers paired with coil springs, and almost no parts that can fail. The electric vehicle has high torque, but the suspension structure is the same as the fuel version, leading to increased load on the half-shafts. We have repaired several vehicles with abnormal noises during acceleration, all due to half-shaft wear. During maintenance, pay attention to checking the rubber bushings of the rear suspension, as aging can cause squeaking.
