Ke Ling 09 is equipped with Volvo SPA protector, and the chassis design adopts the original products of Volvo SPA platform. The structure, design, material and bolt holes are exactly the same, and even the parts are interchangeable. The front subframe is a double-deck steel plate stamped full-frame structure, and the overall layout, design and even the position of fixing bolts are exactly the same as Volvo XC60. The front suspension adopts double wishbone structure, which consists of an upper aluminum alloy wishbone and a lower aluminum alloy wishbone. Double wishbone can bring better control effect, which is generally standard for luxury cars, exactly the same as XC60 of Volvo SPA platform, and even parts can be interchanged. The rear subframe, like Volvo XC60, is a full-frame structure of stamped steel plates. This Lectra 09 uses a composite leaf spring only available on Volvo SPA platform. This material is called GFRP (glass fiber reinforced plastic). This kind of spring not only reduces the weight by 50% compared with the traditional steel spiral spring, but also saves space. At the same time, it plays the role of suspension connecting rod, which further improves the rigidity of suspension.
