The Equinox chassis is built on the GM D2UX platform, with a height of approximately 17cm when fully loaded and about 20cm when unloaded. The chassis refers to the combination of the transmission system, running gear, steering system, and braking system in a vehicle. It supports and installs the car's engine and its various components and assemblies, forming the overall shape of the vehicle, bearing the engine's power, and ensuring normal operation. Here are some methods for chassis maintenance: 1. Regularly check the oil levels of each assembly: This includes the transmission, braking system, power steering system, etc. On one hand, strictly follow the time intervals specified in the manual to replenish or replace fluids at authorized service stations. On the other hand, perform regular self-checks. Generally, you can inspect these during refueling, checking whether the oil in each reservoir is between the upper and lower marks. If it falls below the lower mark, replenish it promptly. If the oil level drops rapidly, it indicates a system leak, which requires immediate identification and repair. 2. Replace worn brake pads promptly: Brake pads and clutch plates are consumables that wear out over time and lose their original functionality. Failure to replace them promptly can lead to accidents. Most vehicles have corresponding warning indicators that will alert the user when replacement is needed.

The Chevrolet Equinox utilizes General Motors' D2UX platform chassis, which is quite impressive—one of the most advanced architectures in its class. The lightweight design reduces the vehicle's weight by nearly 200 kilograms, making it notably agile and fuel-efficient. It incorporates a significant amount of high-strength steel, enhancing overall rigidity, which noticeably improves cornering support and stability during high-speed lane changes. This chassis also prioritizes safety performance, consistently achieving high scores in crash tests. On regular drives, the suspension effectively absorbs road imperfections—neither overly harsh over speed bumps nor rough patches. The all-wheel-drive version boasts well-balanced front-to-rear weight distribution, delivering handling dynamics that rival sedans.

I've been driving the Equinox for almost three years now, and I'm most impressed with its chassis. The manufacturer really invested in equipping it with the GM D2UX platform, making it both stable and comfortable to drive. During daily commutes, the steering wheel feels light and responsive, with minimal body roll when taking corners. At highway speeds, the chassis stays firmly planted to the road. What satisfies me the most is its performance on bumpy roads—the shock absorbers handle minor vibrations exceptionally well, and even large potholes don't produce alarming thuds. The ground clearance is sufficient, making weekend trips on rural dirt roads no problem at all. During maintenance, the mechanic mentioned that the suspension structure is simple yet reliable, and components like the link bushings are reasonably priced.

The Equinox shares the same D2UX platform as the Buick Envision, offering a rigid yet lightweight chassis. It delivers agile steering in urban driving, making parking and U-turns effortless. Its standout feature is excellent ground clearance of approximately 20cm, easily conquering curbs. The chassis boasts effective noise insulation, with well-controlled tire noise at highway speeds. This platform supports 4WD, providing confidence in snowy conditions. Maintenance is straightforward—routine oil changes and lower arm inspections suffice, while the robust multi-link rear suspension ensures durability.
