Automotive engineering, together with aerospace engineering and naval architecture, maybe a branch of auto engineering, incorporating elements of mechanical, electrical, electronic, software, and safety engineering as applied to the look, manufacture and operation of motorcycles, automobiles, and trucks and their respective engineering subsystems. It also includes the modification of vehicles. Manufacturing domain deals with the creation and assembling the parts of automobiles is additionally included in it. The technology field is research-intensive and involves direct application of mathematical models and formulas. The study of engineering is to style, develop, fabricate, and test vehicles or vehicle components from the concept stage to the assembly stage. Production, development, and manufacturing are the three major functions during this field.
