What's the Difference Between Off-Road Vehicles and SUVs?

[LaTyler]

The differences between off-road vehicles and SUVs are as follows: 1. Body Structure: The durability of an SUV is not on the same level as that of an off-road vehicle. Off-road vehicles are equipped with a body-on-frame structure, whereas SUVs typically feature a unibody construction. 2. Suspension: SUVs commonly use four-wheel independent suspension, while off-road vehicles employ solid front and rear axles. 3. Engine: SUVs generally opt for high-revving engines, while off-road vehicles prefer low-revving, high-torque engines. High-revving engines focus on mid-range acceleration and fuel efficiency during highway driving. In contrast, low-revving, high-torque engines emphasize explosive power, which is essential for tasks like climbing hills or escaping tough situations. 4. Four-Wheel Drive System: SUVs usually come with either two-wheel drive or electronically controlled four-wheel drive, whereas off-road vehicles are equipped with mechanical four-wheel drive systems featuring differential locks. The advantages of electronically controlled four-wheel drive include lower demands on driving skills, the ability of the vehicle's computer to correct mistakes, affordability, suitability for urban and highway driving, high comfort levels, and energy efficiency. However, its drawbacks include the inability to manually operate the system, complete reliance on computer control, and no room for subsequent modifications. While it can handle occasional rough terrain, it is primarily designed for highway driving.
