This lesson is designed to be done independently, consecutively, or concurrently with the Rolling Resistance, Transmission, Electric Power Source, and Electric Motor Lessons for the Electric Vehicle (EV) Unit.

Power efficiency is the goal of all good environmentally conscious designs. As you will see throughout the EV unit, there are many factors that influence this efficiency. The goal in this lesson is to determine the effects of the body design on the vehicle’s travel and engine efficiency. Efficiency, practicality, and marketing the product must all be kept in mind when designing the vehicle’s body and determining the material the vehicle will be made of. Students will design, test, and create a prototype of their design as well as market their product to industry and consumers by the end of this lesson.
