The automobile is a type of motorized vehicle designed to carry a large number of passengers. It can be a four-wheeled vehicle with a drivetrain or a two-wheeled vehicle that uses a battery. Both vehicles have seats for passengers and run on diesel or petroleum.
Automobiles have been on the road for a long time. In the 19th century, there was a need for a self-propelling carriage. Edward Butler built the first commercial three-wheeler in 1884. This vehicle had a horizontal single-cylinder gasoline engine that was driven through a chain from the rear wheel.
Another vehicle was the Stout Scarab, which was designed by William Bushnell Stout. This vehicle was a precursor to the minivan and was designed to carry a large number of people.
Vehicles were developed by manufacturers, who used their engineering expertise and scientific research to improve safety, control, and emission-control systems. They also improved the body, chassis, and engines.
In the United States, the Environmental Protection Agency began to regulate motorcycle hydrocarbon emissions in 1980. Motorcycles were limited to 0.8 grams of hydrocarbons and nitric oxides per mile of travel.
In the European Union, stricter limits were imposed on carbon monoxide, nitric oxide, and hydrocarbons. Manufacturers began to compete for market share and create new designs.
Regardless of how the definition is defined, there are a variety of advantages and disadvantages to each. For example, motorcycles are much easier to maintain, requiring fewer parts and less space for parking. However, cars are much easier to tow.
