What Body Design Do Off-Road Vehicles Generally Use?
1 Answers
Off-road vehicles adopt a body-on-frame design because it offers higher rigidity. This type of body design enables the vehicle to handle more challenging and complex road conditions. The rigidity of a unibody design is inferior to that of a body-on-frame design. If a vehicle with a unibody design is frequently used for off-roading, the frame may deform. Therefore, hardcore off-road vehicles use a body-on-frame design. In vehicles with a body-on-frame design, the body shell and chassis are not integrated—they can be completely separated, and the vehicle can still operate normally even when the shell is detached from the chassis. In contrast, vehicles with a unibody design cannot separate the body shell from the chassis. In terms of off-road capability: The body-on-frame design provides higher ground clearance, as well as larger approach and departure angles, resulting in superior off-road performance. Advantages: The body-on-frame design makes it easier to integrate four-wheel-drive systems, whether part-time or full-time, which is also crucial for off-road vehicles.
