How Cars Are Made
The transport sector is one of the largest sources of air pollution and CO2 emissions, and cars are a major contributor. Automobiles are responsible for significant amounts of carbon monoxide, nitrogen oxides, and particulate matter, and nearly 80 percent of the impact is due to fuel consumption and emissions. Particulate matter alone causes 30,000 premature deaths every year. The transport sector also contributes to global warming by burning a third of the world’s petroleum.
The development of automobile technology was swift, thanks to the assembly line and the division of labor. Henry Ford’s improvements enabled even the average American to drive. Automobiles changed the way people lived and worked. By the late 19th century, the mass-produced car industry produced fifteen million vehicles per year. But how did the mass-produced cars get from concept to market? A lot of it has to do with marketing plans. General Motors developed the Companion Make Program, which involved car companies developing and marketing their products to consumers.
Metals are widely used in cars. According to the EPA, nearly 65 percent of the materials used in an average car are made of steel. Steel is a durable and flexible material that bends instead of breaking on impact. Stainless steel is chosen for its resistance to rust. Many car manufacturers use this material in exhaust parts and bolts. And because of its corrosion-resistant nature, cars have a higher fuel efficiency than aluminum-powered cars.
A car’s body is the exterior shell, which surrounds all the mechanical components. Most cars are built with steel, although some are made of stronger plastic or fiberglass. Car bodies feature passenger compartments, hoods, trunks, fenders, and other features to improve their safety and performance. There are many different body styles and models, and they vary in price tremendously. There is a car for everyone – whether it is a sedan, a compact, or a luxurious SUV.
Cars have multiple types of lights to improve visibility and safety. Headlights illuminate the road ahead, making it easier for other drivers to see a vehicle. Other lighting features include amber turn signal lights and red brake lights, which indicate when the driver intends to stop. Side marker lights also improve visibility. Some vehicles also feature interior lights to increase visibility. Besides headlights, a car has interior lights to keep the driver comfortable and safe.
While oil consumption continues to increase globally, there is hope that cars will start to be more fuel-efficient. Vehicles with the highest EPA estimated fuel economy are typically the most fuel-efficient vehicles. But driving habits play a significant role in gas mileage. Listed below are some proven tips that can help you increase the gas mileage of your vehicle. Among the best tips for maximizing fuel efficiency:
The materials used to make cars vary widely. Some are abundant and easy to obtain, while others require tremendous energy during production. Some are also easier to form than others. The combination of materials and processes makes a significant difference in the efficiency of a car, and the environmental footprint it produces. A car’s material composition can impact the speed and safety. The right combination of materials can make a difference in the way it drives, and ultimately in the safety and security of its occupants.
