Automobiles are powered by an internal combustion engine, and they are fueled most often by gasoline (petrol), a liquid petroleum product. They are one of the most universal of modern technologies, and a large industry that employs millions around the world. Automobiles have both promise and peril, however, as they contribute to traffic congestion, air pollution, and even wars. In the modern automobile, a host of mechanical systems work together to power and control the vehicle, keep it safe for passengers, and make it comfortable for drivers to drive.
Automobile manufacturers have developed several different car designs to suit various needs, from off-road driving to high-speed travel on limited-access roads. They have also adapted their design and production processes to reflect new technical developments. Some of these include electric ignition and self-starter, the closed all-steel body, the high-compression engine, and hydraulic brakes. They have likewise improved the suspension, steering, and power transmission. Other changes were driven by marketing plans, such as Alfred P. Sloan’s “companion make” program, whereby buyers could move up from a less expensive model to a more luxurious model as their financial circumstances improved.
In addition to the major car companies, there are many smaller manufacturers that produce niche vehicles or specialty cars. Some of these small producers are specialized in the production of luxury vehicles such as the Mercedes Benz S class, while others specialize in performance cars such as the Porsche 911 GT3.
While the basic components of an automobile have not changed much over the years, there have been significant improvements in the technology of the mechanical and electrical systems. Increasingly sophisticated sensors and control systems have become standard features, while the computer has replaced the simple dashboard instrument panel as a means of controlling the motor, transmission, and other car functions. Safety has become a primary concern. In the US, federal standards have been established for vehicle crashworthiness and emissions control.
The development of the automobile as a practical mode of transportation revolutionized the way people live and worked. It allowed individuals to get where they wanted to go without having to wait on others for rides or adjusting their schedules to the availability of public transportation. Moreover, it reduced the dependence on horses for transportation and made urban life more accessible.
Having a car can be convenient, especially if you have a hectic lifestyle. You can save time by not having to schedule your day according to the bus or train schedule. But owning a vehicle has its disadvantages, including the fact that you have to pay for gas and you may encounter delays while on the road. If you want to get around this issue, consider an alternative form of transport such as an e92 m3 steering wheel.
