This product is specifically designed for the front underbody of the BYD Qin Pro DM-i (including DM dual-mode plug-in hybrid and fuel versions). It is a chassis protection component installed beneath the engine/motor to safeguard core powertrain parts—the engine lower cover (front) . As a key protective component of BYD's DM-i super hybrid system, the lower cover acts as the chassis "armor," silently protecting precision components such as the engine, electric motor, oil pan, and high-voltage wiring harnesses from road debris, sand, mud, and snow, while preventing direct damage to the core powertrain from bottoming out and scraping.

The BYD Qin Pro DM-i is equipped with a 1.5T turbocharged engine + electric motor DM dual-mode plug-in hybrid system, with maximum engine power of 113kW and peak motor power of 110kW, delivering substantial combined system torque. The Qin Pro DM engine adopts a front-mounted layout (exhaust in front, intake in rear), with the exhaust pipe positioned relatively low, placing high-temperature resistance requirements on the engine lower cover. This product optimizes the insulation structure on the inner lining to effectively cope with exhaust pipe heat radiation.

As a professional manufacturer of automotive chassis parts, we develop and produce strictly according to BYD OEM technical standards, using original vehicle 3D data for precision mold development. The mounting holes are 100% precisely matched with the original vehicle for damage-free installation, directly replacing aged or damaged original lower covers, or as an upgrade option for vehicles not originally equipped with protection plates. The product is available in multiple material options including aluminum alloy, manganese steel, and plastic steel to suit different road conditions and usage needs.
