Automobiles and Motorcycles


An automobile, a motor vehicle, is a four wheeled transportation system. It is a popular mode of transport in the United States and Europe. However, it is also considered a threat to the environment as it is known to cause air pollution.

The term “automobile” is often used interchangeably with the terms “motorcycle” or “motorcar.” Most definitions say that they are vehicles that run on roads and that have four wheels. Nevertheless, there is a gray area when it comes to their classification.

Automobiles were first developed in Germany in the late 1800s. After the Great Depression, European manufacturers developed new methods of mass production. This allowed them to produce a large volume of automobiles at a low cost. These techniques were eventually adopted by American automakers.

After World War II, Japan and the United States became major automobile producers. By 1980, the automotive industry had consolidated to become a global manufacturing sector. At that time, approximately one quarter of the world’s passenger cars were built in the United States.

During the 1920s and 1930s, many automakers began to develop aircraft-inspired body styles. Many of them introduced new technologies and equipment to improve stability and safety. They also improved the performance of their engine and drivetrain, as well as safety systems and emission-control systems.

By the early 1990s, the number of passenger cars sold in the United States exceeded 300,000. Despite a weak economy in the United States, the automobile industry was still able to recover. Sales increased from 304,062 in 1990 to 571,580 in 1995. Due to the Asian economic crisis, the number declined to 158,000 in 1998. In 1999, 175,000 vehicles were sold. But the numbers slowly improved in the following years.

By the end of the twentieth century, the number of automobile manufacturers in the United States reached forty-four. In addition, the government provided subsidies to encourage the purchase of automobiles. A chronic shortage of skilled labor in the United States encouraged mechanization of industrial processes. As a result, the automobile became a significant source of income for Americans.

The introduction of mass-production techniques by Henry Ford in 1908 changed the way automakers were able to compete. With new manufacturing techniques, such as the moving assembly line and vanadium steel, Ford’s Model T was able to be produced in great numbers and at a relatively low price.

Before the Model T was introduced, automakers were relying on the same small spark-ignition engines that were used in the pedal cycles. But the invention of the two-stroke cycle made it possible to test new designs.

New manufacturing processes and materials, such as aluminum, have helped to improve the stability and durability of modern automobiles. The weight distribution of the vehicle also plays an important role in a vehicle’s stability. If the weight of the car is distributed to the rear, it becomes less stable. For this reason, a front-mounted engine exploits stability more easily.

Manufacturers are also constantly developing their products and improving the chassis, engines, body, safety systems, and control systems. The automobile is a complex technical system, with thousands of parts. Each year, a new model is introduced to the market.
