The energy efficiency of vehicles with the lightweight feature is better than the heavyweight vehicles because they have less weight on the tires (wheels) and it uses less energy. The less weight it is the better at handling because a lightweight car can pick up speed, and reach higher speeds than a heavier car. The handling of a car is affected by the ground clearance, the tires and the aerodynamics. However, a heavy vehicle had more weights to keep the tires from spinning. In other words, the lower a car is to the ground the greater it handles like it goes up. In my opinion, lighter weighting vehicle is better because the lighter the weight, it picks up speed quicker, the lighter you carry load the better it will work and it will reach higher
