The automobile is a four-wheeled passenger vehicle that is designed for transportation on roads. Modern automobiles are typically powered by internal combustion engines that use gasoline (or diesel fuel) as a source of energy and are sold in a wide range of shapes, sizes, and styles.
The automotive industry is a major force in twentieth-century American history. By the 1920s, it was one of the nation’s largest industries, and it employed more people than any other industry. The automobile changed people’s lives, giving them more personal freedom and access to jobs and services. It also helped create ancillary industries such as steel and petroleum, and it created new businesses like gas stations and convenience stores.
Automobiles are one of the most common modes of transportation in North America, with nearly eight million vehicles on the road. These cars are used to commute between home and work, run errands, take family vacations, and get around the country. They also help to connect us to friends and coworkers across long distances.
When choosing an automobile, it is important to consider your needs and preferences. For example, if you need a car that can handle a lot of cargo and tow heavy loads, look for a truck-based SUV. If you prefer to drive a sleek sportscar with excellent handling and acceleration, then consider a compact convertible such as the 2023 Mazda MX-5 Miata.
In addition, the automobile is a complex technical system with many subsystems that have specific design functions. For example, a car that is designed for off-road driving must have durable and simple systems that can be adapted to extreme operating conditions. On the other hand, a vehicle intended for highway use must have high performance engine power and optimized highway handling and stability.
