Automobiles' aerodynamic qualities and how they changed since 1950?
Aerodynamics is the way air moves around things. Anything that moves through air reacts to aerodynamics. It even acts on cars, since air flows around cars.
1950s cars were some of the most classic, powerful and unsafe cars ever driven. However, the modern designs and acceleration abilities were getting better every year. In design, the outstanding feature of the 1951 model year was the popularity and extension of the “hardtop convertible” introduced in 1950 models. It was announced that air-conditioners would be available as optional equipment on at least three 1953 cars. Two different cars were introduced in 1953: one with a magnesium body and the other was plastic-fiberglass. One of the most noteworthy trends in 1957 was the rise of the station wagon. Before the war, this body style was regarded as a luxury.
For some years, the world's automotive industry has been under pressure to develop vehicles which are less demanding on fossil fuels as the primary source of energy for propulsion and to be less harmful to the environment. Automobile aerodynamics has a significant effect on overall fuel consumption of vehicles. It is now accepted that certain shapes and features give the best aerodynamics. A car is most stable when the Center of pressure lies slightly in front of the Center of gravity. With these new findings and improved aerodynamic qualities, modern automobiles are faster, safer, easier to use and even has less fuel cost.
