What Are Automobiles?


Automobiles are wheeled vehicles that are used for transportation. Although their exact definitions vary, most definitions define them as vehicles with four wheels that seat one to eight people. Automobiles are also much more than mere transportation devices. In fact, automobiles are also considered to be a form of art.

Fuel efficiency standards

The NHTSA is a government agency that sets fuel efficiency standards for automobiles. It largely relies on petitions from low volume manufacturers (LVMs) to determine the most realistic standard for each model year. This way, the agency is already familiar with the technologies that LVMs apply to improve fuel economy. The agency also knows which vehicles will be sold in a particular year.

Types of automobiles

There are many different types of automobiles. There are five major categories: passenger cars, trucks, buses, and vans. Motorcycles are another common type of automobile.

Oil consumption

Oil consumption in automobiles is the loss of oil while the engine is running. This process can be a dangerous one as it can cause the oil level to drop and cause internal engine wear. The causes of oil consumption may range from dirty oil to worn valve stem seals and rings. Another cause is a design flaw in the engine.

Manufacturing process

The automotive industry has been undergoing a dynamic evolution for several decades. Technological advances in the field of manufacturing have led to the development of many new vehicles, shorter development cycles, and increased productivity. However, the automotive industry is also facing intense competition on a global scale. A successful production process requires a high degree of collaboration between automakers and suppliers.

Safety hazards

Safety hazards in automobiles include defects in various parts and systems. These defects put the driver and passengers at risk. For example, a malfunctioned steering system can cause the vehicle to lose control, increasing the risk of an accident. Other defects may affect other parts of the car, including the brakes, suspension, and tires. Some vehicles also have issues with their autopilot systems.


In recent years, consumer advocacy groups and government regulators have increased efforts to monitor automotive defects and to increase public awareness of recall issues. These groups have also criticized agreements between automakers and regulators and weighed in on penalties assessed for failing to comply with recall regulations. The number of automobile recalls has increased in recent years because of increased car sales and greater use of common parts across various automakers.
