ABSTRACT
Over the years many unusual designs have been tried, some with more success than others. The most common is, of course, a rectangular vehicle with a wheel at each corner. A common layout for a standard car is the front-engine, front-wheel drive vehicle. This is because a design with the engine at the front driving the front wheels has a number of advantages. Four-wheel drive combines all the good points mentioned above but makes the vehicle more complicated and therefore expensive. Types of light vehicle can range from small two-seat sports cars to large people carriers or sports utility vehicles. The electrical system covers many aspects such as lighting, wipers and instrumentation. A gearbox is needed because an engine produces power only when turning quite quickly. Motor vehicle companies can range from the very small one-person business to very large main dealers. Filing is the process of removing material when manufacturing something; it is used mostly for finishing operations.
