Automobiles are wheeled motor vehicles that are used for transportation. Most definitions say that they run on roads, seat one to eight people, have four wheels, and are primarily used to transport people. What are some common types of automobiles? Here are a few definitions to give you an idea.
Autonomous vehicles
Autonomous vehicles are already a reality on some streets in the United States. Although many states have adopted legislation regarding the use of autonomous vehicles, others have proposed new requirements. Many lawmakers are also considering a per-mile tax for the autonomous vehicles. Other proposed legislation includes panic buttons and zero-emission vehicle standards. Some states may also enact laws preventing autonomous vehicles from crossing state lines.
Self-propelled vehicles
Self-propelled vehicles use a computer-controlled motor system to propel themselves. They are used in a variety of industries, including transportation and material handling. These vehicles are particularly useful in the delivery of heavy armaments.
Internal combustion engines
The internal combustion engine is a common part of automobiles. Its use has been a goal for automotive engineers for more than a century. Research has been focused on increasing power, reducing emissions, and improving efficiency. Mazda recently announced an innovation that will boost the efficiency of its gasoline engine by 20 to 30 percent. The car is set to hit the market in 2019.
Retractable roofs
Retractable roofs for automobiles are becoming increasingly popular with automakers due to their flexibility and dynamic capabilities. They are also improving the visual appeal of automobiles. The increasing demand for premium vehicles is expected to increase the demand for these systems. As a result, the retractable roof market is expected to grow at almost 10% CAGR over the forecast period. A key driver for this growth is the decline in the cost of production and increasing reliability. Government regulations are also driving the development of these systems.
Assembly line manufacturing
Assembly line manufacturing is a production method that combines continuous movement with interchangeable parts to produce a finished product. Originally, assembly lines were employed in the meatpacking industry, but the concept was introduced to automobile manufacturing by Henry Ford in 1913. It drastically reduced the cost of automobiles, bringing them within the reach of many people. The success of the assembly line encouraged other manufacturers to adopt the new production technique.
