The difference between monocoque body and body-on-frame lies in their structural design: The monocoque body eliminates the independent frame found in body-on-frame vehicles, instead connecting various body structural components together to form what is known as the "beams" of the monocoque body. Body-on-frame construction is commonly seen in some off-road vehicles and trucks, where components such as the cargo compartment, tires, cabin, and engine are mounted on a large steel beam, often referred to as the "frame," hence the term body-on-frame. Nowadays, there are very few options for body-on-frame vehicles, mostly limited to specialized off-road models like the Haval H9, Haval H5, Toyota Prado, Toyota Land Cruiser, and Jeep Wrangler. Therefore, off-road enthusiasts may prefer body-on-frame vehicles. The advantages of monocoque bodies include lighter weight, lower center of gravity, and higher interior space utilization, making them more comfort-oriented.

What are the causes of water leakage in the trunk of the 11th-generation Excelle?

11th-generation Excelle trunk water leakage may be caused by worn or aged sealing strips or trunk deformation. Below are detailed explanations and solutions: 1. Sealing strips: Vehicle waterproofing relies on sealing strips, which are made of rubber material with certain strength and hardness to resist deformation under pressure. Solution: Clean the sealing strips multiple times during spring and autumn using damp cotton for gentle wiping. If the vehicle will be parked for extended periods, perform thorough cleaning beforehand to prevent natural aging. 2. Trunk deformation: Vehicle trunks follow specific design rules with drainage curvature in zones A, B, C, and D. If the trunk's structure gets compromised, severe leakage may occur during rain. Solution: Drain water completely by removing the trunk floor's drain plug.

When removing the rear seat covers, first take out the rear seat cushions, then remove the elastic bands, clips, or other fasteners to take off the rear seat covers. Seat covers are installed for car cleanliness or seat protection. However, many car seats have built-in airbags. In an emergency, if seat covers are installed, the airbags may be restricted, preventing effective protection for rear-seat passengers. For strap-fastened seat covers, the airbags might even explode, causing secondary injuries.
