The Gross Vehicle Weight Rating (GVWR) is the maximum allowable weight of a vehicle, including its own weight plus passengers, cargo, and any additional equipment. For electric trucks and vans, this rating is critical because batteries, motors, and other components can significantly add to the vehicle’s weight. Heavier vehicles require more energy to move, which can reduce efficiency and range. Understanding the GVWR helps manufacturers design EVs that meet performance and safety standards while optimizing for range.
