Does a vehicle center of gravity change when the vehicle is full or empty?

• A. True
• B. False
• C. Depends on load distribution
• D. Not enough data

Answer: (B)

The center of gravity is the point where the vehicle’s total weight is balanced, determined by how mass is distributed inside the vehicle. If you add fuel or cargo but keep it at the same location, the balance point along the vehicle stays essentially where it was; the extra weight sits at the same spot, so the overall center of gravity doesn’t meaningfully shift for practical purposes. The vertical height of the CG might change very slightly due to the added mass, but this does not affect handling in a noticeable way, and the stability is more sensitive to where weight sits within the vehicle than to how much weight you have at that fixed location. The key factor is distribution; moving weight to different areas (like loading more weight on one axle or in the trunk) will shift the center of gravity and affect handling.
