The Big Dog's chassis is already quite high, so it does not come with an additional skid plate. Below is an introduction to the car chassis: Introduction: The chassis refers to the combination of the transmission system, running gear, steering system, and braking system on a car. It supports and installs the car's engine and its various components and assemblies, forming the overall shape of the car, bearing the engine's power, and ensuring normal operation. Function: The role of the chassis is to support and install the car's engine and its various components and assemblies, forming the overall shape of the car. It also receives the engine's power, enabling the car to move and ensuring normal operation. Benefits of Sealing: The protection of the car chassis is often the most overlooked by car owners, or they may not even know what the benefits are. According to professional technicians, the chassis is one of the most vulnerable parts of a car. Applying a protective coating to the chassis can bring at least six major benefits to the owner.

I've been driving the Haval Big Dog 1.5T version for almost a year now, and it didn't come with underbody protection plates from the factory. The salesperson told me at the time that the urban versions don't include protective plates, only the 2.0T four-wheel-drive Pastoral Dog and Howling Celestial Dog versions come with factory-installed engine protection plates. After taking delivery, I installed manganese steel protection plates myself because I often drive on gravel roads when visiting my rural hometown. The plates really do protect against scraping the undercarriage - last time I hit a pothole with a loud bang, but upon inspection, only the paint was scratched off without any deformation. If you're buying a base model, I recommend asking the 4S dealership to include protection plates upon delivery. Installing them yourself outside would only cost about 300-400 yuan, which is much cheaper than repairing a damaged oil pan. Remember to choose plates with cooling holes, otherwise they might affect engine cooling in summer.

As an experienced self-driving enthusiast, I've studied the chassis structure of the Big Dog SUV. The factory-installed underbody protection varies by configuration: 2WD versions generally don't come with any, while the off-road trim gets resin skid plates. Those resin plates are like phone cases - they can handle small rocks but will dent against serious obstacles. I've upgraded to aluminum skid plates myself - lighter than manganese steel but offers sufficient protection. For urban driving, additional protection isn't really necessary as the 20cm ground clearance is adequate. But if you frequently tackle rough terrain, skid plates are absolutely essential. Remember to have mechanics check for loose bolts during maintenance - last time I found two missing bolts. Vehicles without skid plates need extra caution, as the radiator and transmission positioned at the front underside are particularly vulnerable.

When helping a friend pick up their Haval Big Dog, I specifically checked the undercarriage. The 2.0T off-road version comes with black resin protective plates, while the 1.5T version exposes the oil pan without any protection. 4S stores often run promotions offering free installation of protective plates, but these are usually plastic ones. I recommend purchasing a 5mm aluminum alloy plate online—the vehicle comes with pre-drilled mounting holes, making installation possible in just half an hour. Three things to note: avoid steel plates as they're too heavy and increase fuel consumption; ensure the plate isn't too close to the exhaust pipe to prevent overheating; and remember to remove the plate during maintenance for oil changes. For city commuting, installation isn't necessary since the Big Dog's undercarriage comes with a rust-proof coating.
