Why is the body of the Song Classic so heavy?

The reason for the heavy body of the Song Classic is that the Song Classic is an SUV model with a high chassis, which raises the center of gravity, thus making the entire vehicle heavier. The role of the car body: The main functions of the car body are to protect the driver and create a good aerodynamic environment. A good body not only enhances performance but also reflects the owner's personality. In terms of structure, car bodies are mainly divided into two types: body-on-frame and unibody. The impact of an overly heavy car body: The heavier the car, the more fuel is needed to drive it, and the greater the resistance the tires encounter. Therefore, the heavier the car, the more fuel it requires. Moreover, greater weight also necessitates a corresponding engine, and larger displacement engines consume more fuel.

Owners who have driven the Song Classic might share this feeling—the 'thud' when closing the car door sounds particularly solid. This heft mainly comes from a few aspects: First, the chassis uses a significant amount of ultra-high-strength steel, making it feel as steady as a weight pressing down during turns. Second, the sound insulation layers are generously applied, with the front cabin insulation foam and four-door sealing strips being far more substantial compared to joint-venture cars. Third, the battery layout features reinforced double-layer steel plates protecting the battery pack. Fourth, the car's high steel-aluminum hybrid ratio, though adding weight, is reflected in its impressive crash test results. A friend once rear-ended another car—their bumper only got a scratch, while the other car's body was significantly dented.

Last time I accompanied a friend to the 4S dealership to check out a car, the salesperson disassembled the door of the Song Classic to show us—wow! The anti-collision beam inside the door panel was as thick as a water pipe. The car's weight is mainly due to its generous safety features, with high-strength front and rear anti-collision beams and a cage-structure frame. Additionally, the spare tire compartment is fully lined with soundproofing material, and the roof has tempered glass for the panoramic sunroof, which is two to three pounds heavier than a standard sunroof. Although the initial fuel consumption is a bit higher, the car feels rock-solid on the highway, sticking to the road even in crosswinds without any drifting.

The veteran mechanic says this car is like wearing armor—its weight is justified. Among cars in the same price range, its proportion of hot-formed steel ranks in the top three, and the A-pillar can withstand a two-ton impact. The reinforced frame around the battery pack alone weighs thirty kilograms, making it much sturdier than cars that mount the battery under the chassis. The doors are exceptionally thick because they’re fitted with dual sealing strips, which prevent drafts in winter but add to the weight. Then there’s the electric motor under the seats—three sets of motors make it significantly heavier than manual seats. After all, for every 100 kg increase in vehicle weight, crash survival rates improve by about 9%.
