The disclosure generally pertains to systems and methods for assigning alternative energy vehicles to travel routes based on vehicle wear-and-tear ratings. Wear-and-tear ratings may be influenced by factors such as, for example, road grade, travel speed, electric motor use, and battery use, on various travel routes. An example method for determining a wear-and-tear rating of an alternative energy vehicle may involve determining an amount of stress imposed upon an electric motor of an alternative energy vehicle due to a grade of a road on a travel route, and an amount of energy consumed from a battery of the alternative energy vehicle due to a speed of travel on the travel route. The wear-and-tear rating of the alternative energy vehicle may then be determined based on the amount of stress imposed upon the electric motor and/or the amount of energy consumed from the battery on the travel route.
