The chassis refers to the combination of the transmission system, running system, steering system, and braking system in a vehicle. It supports and mounts the car engine and its various components and assemblies, forming the overall shape of the vehicle, bearing the engine's power, and ensuring normal driving. At the same time, a good chassis can ensure the driver's safety. The following is additional information: 1. The XC60 is developed on the SPA platform. Compared to the previous generation, the new XC60 looks more sporty due to changes in body dimensions. 2. In terms of chassis parameters, the domestic and overseas versions maintain the same wheelbase, with the distance between the front and rear axles extended by 91mm, reaching 2865mm, which positively impacts interior space. 3. The lower part of the chassis is very flat, with almost no protrusions visible. The engine underguard and side guards are all present. Although the side guards appear somewhat narrow, they effectively protect the chassis pipelines.

I've disassembled and studied the XC60's chassis, which adopts a combination of front MacPherson independent suspension and rear multi-link independent suspension—a fairly common setup among SUVs in its class. High-strength steel is used in the materials, reducing overall weight and improving fuel efficiency. The chassis design emphasizes balance, with well-executed front-to-rear weight distribution ensuring stable steering without feeling floaty. My favorite part is the optional adaptive air suspension system, which automatically adjusts height based on road conditions, effectively filtering out bumps and delivering a cloud-like smooth ride. Compared to the XC90, the XC60 leans more toward urban comfort, making it ideal for daily commutes. I also noticed the integration of an electronic stability system, working in tandem with anti-roll bars to provide better cornering assistance. Overall, the team clearly put thought into optimizing driving quality.

Driving the XC60 to and from work, the chassis performance has left a deep impression on me—it's as comfortable as a mobile sofa, with top-notch vibration filtering on highways and no jolts on bumpy city roads. The front and rear suspension tuning leans towards comfort yet remains firm, with minimal body roll during turns and no severe nose-diving during emergency braking. It uses a standard four-wheel-drive system, offering high stability in rain or snow, with no skidding during rainy-day braking. I've experienced different modes: in Eco mode, the suspension is softer and smoother, while Sport mode tightens up for a stronger push-back feeling. Compared to the Mercedes GLC, the XC60 focuses more on family practicality, with high space utilization and easy parking. If you commute a lot, this chassis design can reduce driving fatigue, leaving your back and legs comfortable even after a full day of driving.

The safety of the XC60 chassis is my primary concern. It integrates Volvo's City Safety system, which monitors road conditions through chassis sensors and works in conjunction with the automatic emergency braking function to reduce collision risks in critical situations. In terms of materials, the high-strength steel frame enhances impact resistance, and the front and rear crumple zones effectively absorb impact forces. The suspension design is robust, ensuring stable grip at high speeds and reducing the risk of loss of control. In snowy conditions, the chassis's four-wheel drive distribution responds quickly, making it easy to avoid slipping on icy surfaces. Overall, this chassis solution prioritizes passenger protection, making it ideal for family-oriented daily use.

Want some off-road fun? The XC60's chassis can handle light adventures. With sufficient ground clearance, the suspension filters bumps well on gravel or grass roads; optional air suspension allows manual height adjustment to clear obstacles. The four-wheel drive system responds quickly, minimizing slippage on muddy paths. I've tested it on small hills—the chassis frame is sturdy with no odd noises. However, it's not a professional off-roader and struggles slightly on rocky terrain. During , focus on checking suspension bushings to prevent aging from affecting handling.

After servicing so many XC60s, I've noticed a few key points to pay attention to in chassis . The suspension system is quite durable, but after high mileage, shock absorbers or bushings may wear out and cause noise, so it's recommended to inspect them every 10,000 kilometers. Electronic components like sensors for adaptive suspension are prone to dust accumulation, requiring frequent cleaning. The overall structure is robust, and post-collision repair costs are somewhat lower than German counterparts. Avoid overloading during daily driving to extend its lifespan. Also, perform chassis balancing when changing tires to ensure smooth driving.
