Dream Car

...My dream car would be a 1969 Chevy Camaro with a 350 engine and a four speed transmission. The name "Camaro" came from a French word for friend. The decision on the name came down to the last minute, with most of the world sure the car would be named, "The Panther." But the name Camaro fit in with other Chevy names- Corvette, Chevelle, Chevy 2, and Corvair. The main reason the Camaro was introduced was because of the huge success of the Ford Mustang. The Camaro was roughly the same size as the Mustang, a little wider and based more on high performance. The Camaro is one of the last remaining muscle cars still in production today. It is only fitting that buyers still expect maximum performance from their Camaros. It is that expectation that has kept the Camaro alive for all these years, while many other cars have faded away, lost in memory. The Mustang GT only offered the 289- cubic inch or a 390- cubic inch V8 in 1967. The Camaro rolled out with 302, 327, 350, and 396 cubic inch V8's The Camaro's style was much smoother as well. The introduction of the Camaro threw pony car (Mustang) development into frenzy. Before the Camaro, the Mustang and Barracuda were not quite considered full muscle cars. Most serious performance enthusiasts still opted for intermediate sized GTO's or the Chevelle Super Sports (SS). The Camaro changed the image of those sport coupes. The Z28 and the stout SS-396 were more than just a stylish ride. Under the hood Camaros were well...

Car Effiencey

...Full Title Your Name Course Number (eg: SCI 207) Teacher Name Turn in Date Should cars be more efficient? The car has been one of the greatest inventions in the history of the world; it has changed the lives of mankind in ways that could never be imagined. It has seen changes through three centuries, from steam and propulsion to combustion and electric. Throughout these evolutions and the changes to this invention, the global footprint has become negative. Some feel that this is not an issue, however cars emit hazardous toxins that are impacting the environment, and these poisons affect all of mankind on a global scale. These toxins come in the shape of many forms, from greenhouse effects and global warming, to oil and battery pollutants. The researcher will show how developing more efficient vehicles will create jobs, lower emissions, and reduce fuel spending. Cars must be made more efficient to enhance one of mankind’s greatest inventions while continually improving the environment and mitigating the negative global footprint mankind has created. The first vehicle known as a car was created by Nicolas Cugnot, a French military engineer who developed a steam powered road-vehicle fixed to a three-wheeled cart; Cugnot successfully converted the back-and-forth action of a steam piston into rotary motion. Then Belgian-born engineer, Jean Joseph Étienne Lenoir invented and patented a two-stroke, internal combustion engine in 1860. It was...

Car Surfing

...Car surfing just for idiots. By ******* For the British newspaper… Hello. I want to write something to your article in the paper yesterday. Here’s my opinion for car surfing: I don’t have any idea, for what’s going on in their head. I think it’s sick, and I don’t understand why young people want to do that. Car surfing is dangerous, and I think that YouTube has an effect on the young people. When they see these videos on the internet, they think they can do it too. They don’t think about the consequences, before some of their friends, who do it, die or getting hurt. I don’t think that we can blame YouTube for car surfing, and other stuff, but when young people see it, they want to do it. That’s it. If there were videos where people get serious hurt, they may will stop doing it. Young people must had it cut out of cardboard! Young people today do a lot off foolish things, but I think it’s a part of being young. Their behaviour is not all ways the best. They often drink to really much, and walk around in a fog. They do things like stealing food, cars and other things. They’ll fight, and they’ll beat up people they haven’t met before, and they just think it’s funny. There’s a lot of things young people do, there is really stupid. As I mention before, they steal. Stealing is a big thing, like car surfing is. They may do because they think they’re cool or something like that. They’re taking drugs, beside they are drinking, and driving, and May there’s sitting someone on the......

Flying Car

...FLYING CAR Many people dream of having a pleasant road trips, avoid commute, and do less time on trips to arrive at the desired destination faster. Thus, giving us the idea that things would be better if we could fly. Everyday scientist, engineers, anyone in general is trying to find new and better ways for transportation, at the same time making it more economic, safe, and environment friendly. Currently, there is prototypes of flying cars, but have not been perfected in its fuel and design. Once perfected these cars would use less or a better combustible, that wont be as expensive and more sustainable. When this flying car will be available to the public, we can think of how our life would change with this kind of transportation. Not only would we save money on building roads but also in parking lots, tires, and oil. We would have less traffic since the sky has more space, we would arrive at our destination faster letting us enjoy more of our family road trips or even work events. Even the president would be able to attend more events in one day. Business would have higher production and benefits especially in business that do delivery, like UPS and FedEx. Having this flying car can even benefit the planet, reducing pollution, slowing or even stopping global worming. With flying cars people would be in happier moods. Because traffic would rarely happen, people won’t have to wait in the heat on summer days and that will avoid people to get angry or have road rage.......

Smart Car

...Spencer Lutz 4/4/11 Research and analysis The purpose of a mission statement is to describe a firms objectives and the scope of activities it plans on part taking in. In Daimler Chryslers mission statement they state that they aim to have superior products, leading brands, innovative and technological leadership. They also state that they want to grow their global presence and have operational excellence. Also they state they want high performing, inspired people to work for them. These people must also be enthusiastic, disciplined, respectful, and have integrity. The Smart Cars mission is reflected in the marketing strategy by many things. They are marketing a product that is superior to its competitors and very innovative. They also market their cars globally. The smart car delivers value to consumers by offering many different models and sizes of the car; and it has good gas mileage, 33 mpg city and 41 mpg highway. The strengths of the Smart Car are good gas mileage, low CO2 emissions, and they are cost efficient. The weaknesses of the smart car are its slow, it can only fit two people, and it requires premium fuel. The opportunities of the smart car are it already has a 100% electric car and can produce more, as gas prices rise people will be looking for more fuel efficient vehicles or alternative fuel vehicles and Smart provides them both, and they are looking to create even more innovative technology for the Smart car. The threats of the smart car are...

Car Rental

...A car rental or car hire agency is a company that rents automobiles for short periods of time (generally ranging from a few hours to a few weeks) for a fee. It is often organized with numerous local branches (which allow a user to return a vehicle to a different location), and primarily located near airports or busy city areas and often complemented by a website allowing online reservations. Car rental agencies primarily serve people who have a car that is temporarily out of reach or out of service, for example travellers who are out of town or owners of damaged or destroyed vehicles who are awaiting repair or insurance compensation. Because of the variety of sizes of their vehicles, car rental agencies may also serve the self-moving industry needs, by renting vans or trucks, and in certain markets other types of vehicles such as motorcycles or scooters may also be offered. Alongside the basic rental of a vehicle, car rental agencies typically also offer extra products such as insurance, global positioning system (GPS) navigation systems, entertainment systems. Although some car rental companies provide self-moving cars which are often trucks and vans to customers with house moving purpose, most car rental companies offer cars such as economy cars, midsize cars, full size cars, standard cars, premium cars, SUV mostly to travelers. From this point, Car rental companies provide transportation for travelers who temporary need cars in the travel destination, so car...

Since last century, with the development of modern technology, all modes of transport are improving all the time, which makes people’s lives become more and more convenient. In fact, transport has played a significantly vital role in society. Business cannot be done without vehicles. To a large extent, economy relies on good transport and accessibility. However, some transport problems appear as the society and economy development. For example, people rely on vehicles too much makes it that too many cars on the road, which results in that traffic congestion is normal in big cities, as well as environmental pollution. In addition, it is not all people share the equal opportunities due to imbalanced development in different regions. Some rural areas have poor accessibility and poor public transport.

Car Services

...Problem: Car Services Ltd (CSL) rends motor vehicle breakdown recovery service to its members. It attracts new members through a television advertising campaign that encourages potential clients to telephone a free call number for further information and the opportunity to immediately enroll with a credit card. Members are offered the choice of three levels of annual service contract in descending order of coverage and price: Gold, Silver and Standard. The telephone inquiries come through to a call centre staffed by CSL employees at the company’s premises who are paid a basic salary and a bonus of each new member that they successfully enroll. Located in the same building on another floor is the Car Hospital (CH) team who take the calls from the stranded motorists and arrange for a franchised garage to deal with the breakdown. These garages are independently owned and CSL pay them a fee for every callout that they undertake. CSL has recently (after January 2004) commenced employing trained mechanics on enhanced salaries to dispense technical advice to members on the telephone in the hope that a proportion of the call-outs to franchised garages will be avoided. Detailed information on costs, revenues, business activity and staff is displayed in the following tables. Table 1 Cost, Revenue and business Activity data for 2004 | |Gold |Silver |Standard...

Zip Car

...1 Zip car aims to be a convenient and fast method of renting cars especially If you live a lifestyle where you dont need a car all the time it is very ideal because people dont want to go through the hassle of renting a car for small tasks so they borrow their friends cars which can also be embarassing. Zip car offers the huge benefit of saving them time and money. 2 Zip car believes in selling an urban lifestyle and promotingenvironmental consciousness by providing the car that you want in a very convenient and accessible way and at the same time sharing it with people who are environmentally conscious. Zip car offers cars to people that want to have the accessibility to a car whenever and wherever they need it at an affordable price i.e. people that prefer to share a car rather than actually having one due to various reasons Zip car “delivers wheels where you want them” 3 Positioning based on beliefs and values is stronger because when a company is able to build itself on beliefs and values people will share those same ideas, you are connecting with the minds of people and it can have a lot of positive effect rather than when you are concerned about the benefits experience. it allows a relationship to build and form with just as zipsters were able to experience.

A definite plus to......

Car Revelutionary

...TITLE By: Soojeong Choe For: Ms. Pinto Thursday, July 7, 2011 Cars revolutionize transportation but walking is still the best. Automobiles use gas that emits carbon dioxide which causes the world to heat up. Big powers come with big responsibilities; there is no surprise that the car has many financial responsibilities. Cars require practically no work to make it move and it resulted in losing health related benefits. Walking is better than driving because it is environmentally friendly, it has financial benefits, and it has far more health advantages. First, driving ruins the environment. For an automobile to function, it requires gas, and when the gas is used up, it becomes carbon dioxide that traps heat near the Earth’s surface. Greenhouses gases are necessary for influencing the amount of the sun’s energy being absorbed into earth and being radiated back into space. However, the overload of the greenhouse gases, which is caused by the increase in gas emissions, can cause the earth surface to heat up. This is called global warming which will raise the sea level by 18 to 59 centimetres if all the glaciers melt. This change in ecosystems and destruction in habitats caused by the rising sea level will also result in the extinctions of many species. Since cars release greenhouse gases, walking is therefore a better choice because it won’t exacerbate the tragedy of global warming. Additionally, driving has financial disadvantages compare to walking. Walking requires...

Flying Car

...A flying car is hypothetical personal aircraft that provides door-to-door aerial transportation (e.g., from home to work or to the supermarket) as conveniently as a car but without the requirement for roads, runways or other specially prepared operating areas. In addition, the aircraft lacks any visible means of lift (unlike fixed-wing aircraft and helicopters), thus allowing it to be operated in urban areas and close to buildings, people and other obstructions. Fulfillment of some of these goals is being attempted by personal air vehicles being developed. The term "flying car" has also been used to refer to roadable aircraft and hovercars. The flying car has been depicted in works of fantasy and science fiction such as Chitty Chitty Bang Bang, Harry Potter and the Chamber of Secrets, The Jetsons, Star Wars, Blade Runner, Back to the Future Part II and The Fifth Element as well as in technology magazines such as Popular Science, Popular Mechanics, and Mechanix Illustrated.[1] The flying car was and remains a common feature of science fiction and conceptions of the future, including imagined near futures such as those of the 21st century. As an example, less than a month before the turn of the millennium the U.S. journalist Gail Collins noted: Here we are, less than a month until the turn of the millennium, and what I want to know is, what happened to the flying cars? We're about to become Americans of the 21st century. People have been predicting what we'd be like......

Easy Car

... facilities and qualities are provided to customers as otherwise they may switch to other transport services. The goals and the approaches used by the company are quite effective but need to concentrate more on service quality rather than only focusing on low price. At EasyCar, customers were required to wait for long time, they were not repaid for cancellations and they were also anticipated to pay for cleaning of cars and fuelling of gas (A Case Study Analysis on EasyCar.com, n.d.). All these approaches and strategies of the company were dissatisfying its customers. In addition to this, the company was having only one or two employees at its each location. Each of its employees was dealing with several customers that create severe dissatisfaction among its customers (John & Luis, 2005). Nowadays, customers want quality and they does not consider price, if served with high quality. This need to be kept in mind by EasyCar so that it can also become able in not compromising cost on the basis of quality or facilities it may offer to its customers. With the help of some changes, it may easily and effectively attain all its 2004 goals. ...

Car Accidents

...Causes of Car Accidents For many people, driving a vehicle is an everyday activity. People rely on their cars to get to work, school, and other important places. However, driving can be dangerous, and although weather conditions and car malfunctions can contribute to accidents, the behavior of drivers is most often the cause of accidents. The three main causes of car accidents are poorly trained drivers, distracted drivers, and impaired drivers. One cause of car accidents is poorly trained drivers. Drivers who don’t follow the rules of the road can be putting themselves and others at risk. For example, drivers who exceed the speed limit will have a more difficult time stopping or turning if something, such as an animal, crosses their path. In addition, there are road signs that drivers need to recognize, understand, and obey. Other drivers cannot tell how people who do not obey road signs will drive, and this unpredictability can lead to accidents. Finally, not checking blind spots and not being aware of one’s surroundings can result in a collision. A driver who is not aware of what is around his or her vehicle may crash into other cars or objects, not realizing they are there. For these reasons, poorly trained drivers can cause accidents. Distracted drivers are another cause of car accidents. Driving is a task that requires the driver’s full attention, so performing other tasks while driving can lead to an accident. For example, people who talk on their cell phone while...
