Hybrid technology, since its inception has been designed to reduce the impact of the combustion engine on the environment. However, the brand new generation of supercars from McLaren, Ferrari and Porsche has exploited the powerful aspects of the electric motor to enhance the capabilities of the internal combustion engine. Since the first glimpse of the Porsche 918 at the Geneva motor show in 2010 [Top Gear Australia, 2010], Porsche has endlessly continued to further research and develop the system to maximise the potential of the hybrid system. With a 4.6 litre V8 producing 608 bhp and two electric motors the 918 produces an astounding 887 bhp resulting in an extremely impressive top speed of 340 km/h [Porsche Automobil Holding SE, 2014]. But, lets no dwell on the irreverent top speed as the engineering behind the 918 is dedicated to the track. That is, how it converts this power and torque into angular acceleration. How it does this? A traditional petrol powered engine delivers a small amount of torque at low rpms, resulting in a lower angular acceleration, by utilising the electric motors, the 918 can generate 680 Nm of torque at 800 rpm. By employing the electric motors when the petrol motor is least efficient, the ability of these supercars has reached a new level.
Although a 4.6 Litre V8 supercar may seem to be a tool of the past, the Porsche 918 demonstrates the potential of the hybrid engine producing only 70g/km of Carbon dioxide to the Toyota Prius’ (the face of efficiency) 89g/km and similarly with fuel consumption 3.3L/100km compared to 3.9/100km [Toyota, 2014]. Which means that the joy of driving can be preserved as humanity source of oil is reaching a point where cars are becoming less viable as an option. Until so...

...ring. But in today’s modern society, the problems we face are more evolved than those face by engineers thousands of years ago. By reaching a peak in raw ability of automobiles, the necessity these days is to refine the efficiency in order to maintain our way of life, whilst preserving it for future generations.
The principal goals of the Porsche 918 is to develop a supercar that embraces all the technological evolutions in the past couple of years, while making it as efficient as possible. Why does this matter? To the normal person, sure it may be interesting, but to those who appreciate driving, the Porsche 918 and other cars alike, the LaFerrari, McLaren P1 and the Lexus LF-LC, conserve the thrills of driving, while making it possible to do so without compromising the already strained fuel source that is available to us at the moment and into the future.
Driven in large part by global initiatives and the potential for stringent regulations, the past decade or two has seen a marked increase in the importance of improvements with respect to environmental standards, including emissions and increases in fuel economy. In 2002, Cummins Emissions Solutions was launched after the need was identified for an emission solution that would help engines meet future regulations. In 2006, Cummins pioneered a hybrid diesel-electric bus which reduced fuel consumption and greenhouse gasses by more than 30 percent and me...
According to Cars Direct website, hybrid cars can reach 51 MPG wish destroy all gasoline and diesel efficiency expectations. This high efficiency yield to two main reasons: hybrid car tend to be lightweight, and the cooperating between the gasoline engine and the electric motor. ” According to consumer reports tests, most hybrid cars have better fuel economy than their gas-only counterparts “ (Barett, “The Difference Between Gas and Hybrid Vehicles”). This is obvious if we compare between a hybrid and gasoline cars which have the same name: the hybrid Honda civic average efficiency is 40 MPG while the standard Honda civic average efficiency is 29 MPG, the hybrid Hyundai sonata average efficiency is 33 MPG while the standard Hyundai sonata average efficiency is 27 MPG, and the hybrid Ford fusion average efficiency is 34 MPG while the standard Ford fusion average efficiency is 24 MPG (Barett) [average efficiency is the average between the car efficiency in city and its efficiency in highway
The admiration of Hybrid cars in the United States market to this day is increasing at a rapid rate. Hybrid cars have been in high demand by buyers all over the United States. As time progresses, more and more consumers grasp that the upcoming hysteria of hybrid vehicles are not only better for the environment, but are all around much economical to our prodigious populace. The growing popularity of hybrid cars is due to an increase in the diverse archetypal choices available, the time-tested expertise and the economical valuing. A vehicle is deliberated as a hybrid if it utilizes more than one form of energy to attain momentum. With a customary internal-combustion engine and fuel tank, as well as one or more electric motors and a battery pack, this makes this type of vehicle is considerably dissimilar than other Hybrid’s out there.
The beginning of hybrid cars goes back to the 20th century. The Paris Exposition of 1900 included the Lohner-Porsche Elektromobil which is the first ever hybrid car. The inventor of the Lohner-Porsche Elektromobil was a 23 year old engineer named Ferdinand Porsche. Porsche is known today for his Volkswagen cars and for the famous sport cars designed by his son. He created a vehicle that could travel 38 miles on electricity alone. Porsche partnered with Jacob Lohner who wanted to develop motorcars that had incorporated coaches. The gas-powered cars at that time were very noisy and difficult to start. Porsche created battery-powered electric motors and put them in the front-wheel hubs to produce a front-wheel drive car. He also added an internal combustion gasoline engine so the batteries in the car could be charged. Sadly, the Lohner-Porsche could only reach up to 35 miles an hour. The idea of hybrid cars decreased during the years of growth in the modern automobile industry. This period brought a national highway system in the United States and gasoline was inexpensive. The concerns with auto emissions brought back the idea of hybrid cars. C. Russell Feldman, one of the founders of Motorola, decided to explore the possibilities of hybrid cars again. He contacted an electrical engineer named Victor Wouk to see if a hybrid car could work in society. Wouk found out that the batteries in the hybrid cars did not have the energy to produce a lot of speed and range. In the 1960’s, Wouk combined the low-emissions benefit of an electric car with the power and range of a gasoline engine to create a hybrid car. To make his hybrid car ideas real, Victor Wouk and his partner Charles Rosen formed the company called the Petro-E...
Throughout time gasoline fuel has been the major fuel used in order to power cars. Even today the majority of people who have cars they are typically gasoline powered cars. Although gasoline has been improved throughout time, the world today now needs alternatives to gasoline since it is hurting the world. The world is in need of an alternative that will help the environment. One major and successful alternative is the hybrid car.The creation of the hybrid car will greatly affect the world positively.

Being a member of the future generation of innovators and leaders, I feel that this research combined with my fascination of automobiles could lead to a clearer understanding of how I can help improve the automobile. In a world that is highly connected by roads, if the problem of using petroleum-based fuels is not solved, the entire gas-guzzling world could come to a standstill. This apocalyptic halt would cease all travel and we would be thrown back to a more primitive standing. However, if we research and find an alternative ahead of time, we would be able to transiti...

Most American cars are not hybrids or fuel-efficient, they are usually big SUV’s or trucks that get eighteen to ten miles per gallon. Most of Hondas, Toyotas, and Hyundai’s get around 20 to 30 miles per gallon, and hybrids get 50 miles per gallon. Peoples demand fuel-efficient cars because oil is i...
Innovation is the most critical component of a well-known luxury sports car manufacturing brand which has to maintain its legacy and compete with many known European automakers as well as newly booming tech companies. Porsche has being focused on gasoline sports cars which were very successful in last few decades but might not be the future of the industry and many of Porsche's competitors are engineering electric and hybrid motor vehicles, and also recent startups like Tesla motors are changing the whole phase of transportation technologies with their innovation in electric motors and batteries, beating gasoline motor vehicles. In order to stay on par with these future engineering marvels , traditional sports car manufacturers like Porsche
"In the first hundred years of active life, it has been described as a menace ands a blessing, a blight and a godsend, as a savior of our countryside and cities, and as their curse, as socially divisive and the greatest social leveler. It has been worshipped and reviled, celebrated and scorned." The automobile is an invention that has had a tremendous impact on society. The automobile has taken diverse segments of the American population; farmers, small town residents and urban dwellers and given them access to the same opportunities and experiences. Autos have given us motels, shopping plazas, drive-thru’s, vacations, commuting, and, certainly not the least, suburbia. The genesis of the automobile is one of the most profound and important chapters in the development of American culture.
The world of technology is ever changing and advancing. With the automotive industry in play technology is constantly surpassing what is available today with what can be done for tomorrow. Technology and the automotive industry go hand in hand with constant improvement to components of cars. Due to technology advancement there is competition within the car industry, especially between American car companies and European car companies. European car companies provide their buyers with innovative variety and revolutionary luxuries. European car technology is superior to American car technology due to their safety, entertainment, and luxury features.
Hybrid cars use both gas and electric. The gasoline engine is the primary source of power, while the electric motor is used at low speeds. Emissions levels are reduced because the gasoline engine shuts off at low speeds. An additional benefit of the parallel configuration is that no outside source of electric power is required because the engine itself generates the required electricity. A Hybrid Electric Vehicle known as HEV have several advantages over traditional internal combustion engine (ICE) vehicles: Regenerative braking capability, which helps minimize the energy lost when driving. Engine is sized to average load, not peak load, which reduces the weight of the engine. Fuel efficiency is greatly increased, while emissions are greatly decreased. HEVs can be operated using alternative fuels; therefore they need not be depended on fossil fuels (http://www.ott.doe.gov/hev/what.html#hev). Another great thing about these machines is the mpg; on the average, a hybrid car gets anywhere from 55-70mpg on the hwy. This is what makes the car all worth having. Now all this sounds good, but there are some issues that must be addressed.
Cars are the ultimate symbol of independence and individualism. They offer more than freedom. No other man made creation but car fulfills a man’s ego. Technology has been the evidence of how cars have evolved for about more than a century now. From a first car packing a single cylinder 958cc, 0.75hp engine to today’s most powerful 8000cc W16, 1300bhp Veyron. We live in such an engineering savvy era where even an increase of few grams in a vehicle’s weight means going back to the drawing board to get unerring dynamic performance. And for these exuberant reasons, mechanical engineering was a mere choice rather than a chance for me.
Vehicles in this day and time are nothing like what they used to be. Over half of the car manufacturers are now trying to build new cars and trucks to be as fuel efficient as they can be. Although hybrids conserve more gas than standard vehicles do, they use gas, also. Hybrids do not use as much gas as the ol...
