Recommended: Evolution of cars essay

Cars, a mode of transport used in all our daily lives. Over decades cars are evolving and being revolutionized by science to improve efficiency and safety. Efficiency defines how fast our cars move, how much fuel they waste per mile, how safe our cars keep us, how proficiently a car drives. To keep our cars productive there are many chemical reactions that occur to keep these factors perfect. The two that are primarily focused about in the essay are fuel combustion and airbags.

Every instance the car is in use there is a massive chance of a safety breach and injury. The airbag will instantly minimize the effect of the large force from the accident and protect the passengers. It halts the forward motion of the passenger in less than a fraction …show more content…

An example of an efficient car that has been successful due to scientific engineering is the Toyota Prius. The worlds top selling hybrid car with cumulative global sales of over 3 million units by June 2013. The Toyota Prius’ tailpipe emissions (grams per kilometer CO2) is 82g/km. While another popular car such as the Toyota Land Cruiser’s tailpipe emissions is 214 g/km. This shows how after scientific innovations a hybrid car, that is electric and fuel powered car, has evolved into one of the most popular and has 132g/km less than the Toyota Land Cruiser.

This proves how science has incorporated the fuel combustion reaction in the car and has evolved into making it more efficient and more popular than ever by minimizing the amount of pollutants it releases. Personally I believe that these innovations have bettered society as a whole as the science in these reactions has not only made automotive vehicles safer and quicker but more efficient in releasing pollutants as well. The cars of today have been altered by science to make a superior vehicle that will not only benefit us but also the future of the planet in a large

  • Hypercar: An Improved Tomorrow

    2351 Words  | 5 Pages

    The majority of people, especially in America, cannot go about their daily lives without a car. Automobiles have instilled themselves in peoples’ lives and shown their usefulness since their debut in 1769. Since then, humans have redesigned and refined the automobile thousands of times, each time making the vehicle more efficient and economical than before. Now as the world approaches an ethical decision to dwarf all others, many people look toward automotives for yet another change. The emergence of the hypercar due to ecological turmoil exemplifies the change the world has demanded. Hypercars alter everything people know about automotives, modern ecology, and fuel efficiency. Not only do hypercars offer a solution to many ecological problems humans are faced with now, they also represent the only logical area for the automotive industry, and by some stretch American society, to expand.

    Automobiles play a major role in today's society. Almost every American owns at least one motorized transportation vehicle. Some say they make our lives better by reaching places faster than before. Others say they are a harmful to the environment. Have they made our society better or worse? They may be fast, but do we as humans want our environment to suffer because of time. Face it, cars pollute. And they release destructive chemicals into the air. Air pollution can threaten the health of many subjects in the environment including human beings.

  • Fuel Economy in American Automobiles

    1366 Words  | 3 Pages

    Fuel efficiency in automobiles has become a topic of much discussion in recent years in the United States. This is due largely to the environmental devastation that fuel emissions cause, but it is also sparked by the rising fuel costs. Making cars with high fuel efficiency not only saves consumers money, but also will drastically reduce the pollution that is caused by emissions. Today automakers are putting a tremendous amount of effort into making their cars more fuel efficient, both to meet government regulations and to make their car more appealing to the consumer.

  • Gasoline Dependence

    1876 Words  | 4 Pages

    For over 100 years, the automobile industry has relied on gasoline as its main source of fuel. Gasoline is a colorless, highly flammable substance used in internal combustion engines. It is a fossil fuel made from crude oil, a natural gas formed from the remains of ancient plants and animals (Webster‘s Dictionary). Gasoline has positively influenced our way of life by providing convenient, on demand transportation. It has created a global economy that moves people and goods faster and more easily than ever imagined (Povey 12). Although a seemingly perfect substance, it has unprecedented flaws. The tremendous political, environmental, and economic problems resultant from the excessive use of gasoline leads to the conclusion that the automobile industry should not continue to rely on this source of fuel.

  • Biofuel and The Racing Industry

    1086 Words  | 3 Pages

    The ecologists are of the opinion that the racing industry is an unnecessary burden for the society, that it does not serve any purpose. But the fact is that the racing industry is just like any other industry that is driven by diesel fuels like car manufacturing and airplane development. If these two consumer goods are considered an important part of human technological innovation, there is no need to sideline the racing industry. On the basis of this, we can also say that using biofuels for racing is preposterous because the biofuels cannot give the thrust that the racing cars need in order to compete. Biofuels are not of high-octane in nature; diesel fuels are. Biofuel cannot be characterized as an energy rich fuel. Using biofuel instead of diesel fuel will negatively impact the performance of racing cars, leading to heavy losses for the racing industry (The Royal Society 08).

  • The Electric Car

    1573 Words  | 4 Pages

    As humans delve into the twenty-first century, scientific research continues at an exponentially increasing rate. While the work of researchers seems to affect people in positive ways, the common debate among the general population is whether or not there is a limit to how far scientists can take their research and impact the future of society. The changes that scientists induce upon society often escape foresight, such as diseases, dangerous paints, and other products that do not pass the test of time. One big issue that is fiercely debated is how to go about switching to alternative-fuel-source automobiles, given that the world’s supply of oil will run dry relatively soon. The electric car seems to be the best candidate as a replacement for the moment, but many people are still weary about completely discarding the trusty internal combustion engine for an invention barely as old as the people who will buy them. The electric fuel is promising, but it has not been around long enough to undergo the test of time needed for mass acceptance. Here the more direct question arises: is the electric car the solution to a more economically responsible car?

    The journey from that idea and the airbags that we have now has been very long. Today, airbags are a necessary in every car and are designed to act as an extra safety device aside of seat belts. But a lot of people are looking quite sceptical at the air bag safety, because there was a lot of accidents where the airbag didn’t react or it did react, but it didn’t help but killed the driver or the passenger. Since 1991 there was 238 counted just because of air

  • Hybrid Vehicles and Their Effect on the Environment

    1905 Words  | 4 Pages

    Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.

  • Physics Of Collisions Essay

    1365 Words  | 3 Pages

    When it comes to cars, there are plenty of safety features incorporated by manufactures to ensure a smooth and safe ride. Some of these features seat belts, airbags, and antilock brakes. Nowadays, there have been great improvements to technology within cars to aid in the avoidance of collisions altogether. Examples of these technologies include blind spot detection, backup cameras, 360-degree cameras, and autonomous driving. Many of these newer safety features are there to avoid collisions. However, whenever a collision does occur, there is not much there to protect passengers in the rear of the car. Looking into this, there is evidence that shows that rear passengers do obtain injuries in collisions and pose the threat of contributing to others injuries. So, why are rear passenger airbags not standard in your vehicle?

    The fast population growth rate of humans means that the necessity for transportation vehicles is also enormously increasing. Studies have shown that in 1999 the worldwide number of vehicles registered was 700 million. From this huge number of vehicles, the US has a large share, which includes 200 million cars and light trucks. The number of cars worldwide also grew three times faster Competition for good things like public health, making the earth safe to live are positive aspects of competition, but global competition can also have a downside concerning the environment. This is true for the production of vehicles, as companies are coming with designs and new models with improved engines, but fuel consumption and the pollution of the air remains the same.
