Are all SUVs unstable at high speeds?

SUVs are far less stable than sedans when driving at high speeds. Here are the relevant details: SUV Center of Gravity: Explaining the concept of center of gravity from a theoretical physics perspective could easily fill tens of thousands of words. To simplify, for a car, the center of gravity refers to the distance of the heaviest components relative to the ground. Components like the engine, transmission, and fuel tank are generally installed in the lower part of the vehicle. The shape, size, and height of these components are closely related to the vehicle's center of gravity. First, all else being equal, the higher these components are installed, the higher the center of gravity will be—this is easy to understand. Shape: Imagine two buildings of similar weight: one is a tall reinforced concrete skyscraper, and the other is a short stone house. If an earthquake occurs, which building is more likely to collapse? Undoubtedly, the taller one is more prone to collapse. The same principle applies to cars. The center of gravity height brought by an inline engine is inevitably higher than that of a V-type engine, and the center of gravity of a V-type engine is also higher than that of a horizontally opposed engine.
I have five years of experience driving SUVs on highways, and as a family car driver, I find most SUVs quite stable—not all of them are unstable. For example, my Honda CR-V is very steady when cruising on the highway; although the center of gravity is high, the suspension design and vehicle weight help offset any swaying sensation. The key is maintaining the tires: regularly checking tire pressure and wear. If the tire pressure is too low or the tires are old, the vehicle can easily become slippery and unstable. There are also significant differences between models—compact SUVs might wobble on windy days, but mid-sized models like the Highlander are much more solid. When driving, I avoid sudden acceleration or sharp turns, as smooth operation enhances stability. Additionally, modern SUVs come with electronic stability control, which automatically corrects roll issues, making high-speed driving safer and more reliable. Don’t be misled by the shortcomings of older models—choose the right SUV and perform basic maintenance to enjoy a comfortable journey.
As an automotive enthusiast, I find that the stability of SUVs on highways is often misunderstood. Early SUVs with high centers of gravity were indeed prone to swaying, but technological advancements like air suspension and electronic stability systems have significantly improved high-speed performance. My current Mazda CX-5 feels incredibly stable on highways, maintaining balance even on uneven road surfaces. Tire selection is crucial: high-performance or all-season tires can enhance grip and prevent instability. If your vehicle feels shaky, check for wear or aging in suspension components; upgrades can noticeably improve handling. In terms of models, urban SUVs like the Toyota RAV4 are designed with highway stability in mind, while off-road-oriented SUVs may perform slightly less well at high speeds. Overall, not all SUVs are unstable—maintenance and driving habits play key roles.
