Difference Between Monocoque and Body-on-Frame?

[StGabrielle]

Here are the differences between monocoque and body-on-frame: 1. Function: A monocoque body not only has its inherent load-bearing function but also directly withstands various load forces. The advantage of a body-on-frame is that it has an independent frame, higher chassis strength, and better resistance to bumps. Additionally, uneven forces on the four wheels are borne by the frame and not transmitted to the body. 2. Advantages: The monocoque body offers significant improvements in both safety and stability, with benefits such as lower weight, reduced height, and easier assembly. The body-on-frame's advantages include an independent frame, higher chassis strength, and better resistance to bumps. 3. Safety: In dangerous situations (such as a rollover), the heavy chassis of a body-on-frame can pose a fatal threat to the relatively weaker body. The monocoque is more stable and offers better safety performance.
