Motor vehicle science has the aim of improving the motor vehicle efficiency and lowering transportation costs. This can be achieved if the average speed of cars and trucks is increased and the fuel consumption decreased assuring also safety of motion and comfort for the driver and passengers. Knowledge of the motor vehicle fundamentals is indispensable for designing and refining new models and also for selecting appropriate types of motor vehicles. The theoretical conclusions serve as the basis for estimating travelling stock efficiency and transportation cost. These conclusions also underlie the calculation of car parts for strength and durability.This book provides various aspects of Motor Vehicle written in a simple and lucid style to help the reader grasp the information quickly and easily. The book contains 16 chapters and each chapter present update material sufficient to meet the students expectations from a basic textbook.
