Automotive engineering, along with aerospace engineering and naval architechture is a branch of vehicle engineering, incorporating elements of mechanical, electronic, electric, software and safety engineering as applied to the design, manufacture and operation of motor cycles and trucks and their respective engineering subsystems. It also includes modification of vehicles. Manufacturing domain deals with the creation and assembling the whole parts of automobiles is also included in it. The automotive engineering field is research -intensive and involves direct application of mathematical models and formulas. The study of automotive engineering is to design, develop, fabricate, and test vehicles or vehicle components from the concept stage to production stage. Production, development, and manufacturing are the three major functions in this field.
