Automobiles are wheeled vehicles that carry people and are propelled by an internal combustion engine fueled mostly by gasoline, but also by other liquid petroleum fuels such as diesel or kerosene. The automobile has become one of the most common and widespread of modern inventions, with more than 1.4 billion cars in operation worldwide. An automobile is a complex technical system consisting of thousands of subsystems with specific design functions.
In the beginning of the 20th century, automobiles became more affordable for middle class families. People who had their own cars gained more freedom of movement within cities and between towns. This led to the development of paved highways. It also helped to create more jobs to support the growth of industries that produced automobiles and provided services like gas stations. The automobile also contributed to the empowerment of women, as they were able to travel on their own without having to depend on men for transportation.
The earliest automobiles were powered by steam engines attached to wagons. In the late 1800s, new technology developed that allowed for more efficient steam engines and later electric motors. But the most significant change came with the introduction of the gasoline internal combustion engine in the early 1900s. This revolution allowed automobiles to become faster and more comfortable than ever before.
Modern automobiles are primarily powered by a gas-powered internal combustion engine with four or more wheels and seating for one to seven passengers. Most have a transmission that varies the speed of the engine and the amount of power being delivered to the wheels. Some have regenerative brakes that turn some of the energy from the vehicle’s movement back into electricity to recharge the battery.
Automobiles can be used to transport goods as well as passengers, but they are mainly built for passenger transportation and are not designed to carry large amounts of cargo. The vast majority of vehicles built are sedans, but other types of automobiles include SUVs, vans, and trucks. The automobile is an extremely versatile machine, but it has its downsides. Its primary drawback is its dependency on fossil fuels, which are becoming increasingly scarce and environmentally hazardous. The use of an automobile also requires individuals to spend time maintaining their vehicle and keeping up with its insurance, tags and license.
Even though shoppers are flocking to SUVs, the midsize family sedan remains a very popular model. The Honda Accord has been the leader in this segment for decades, but other sedans are catching up. The Kia K5 is a strong competitor with its sporty styling and features. The Mazda 6 is another model to consider, offering a refined interior and sporty performance.
