Electric cars vs the gas oh line cars

In the next ten years what the average American drives will be very different than today. Electric cars may phase out gasoline (Gasoline is also known as petrol) in the next couple of decade. Electric cars produce no tailpipe emissions and are much cheaper to fill up than the more common gasoline vehicles. Switching to electric cars will have more benefits than drawbacks in comparison to other fuels such as petrol and diesel. In order to switch to electric cars America's electric capacity will have to increase. In the next few years electric cars will also have new upgrades to increase practicality, range and longevity which may convince people to switch. The only major concerns in the market today is an electric car's driving range and the number of charging stations available across the nation. These problems are likely to be solved within the next decade.

Although some Americans do not want to buy a fully electric vehicle yet there are many benefits to owning one. One of the main reasons people are considering them is because the low cost of powering an electric vehicle. “Drivers struggle with gasoline prices well over four dollars a gallon, and a cumulative 60 billion dollars was spent on gasoline during the past year alone”(CalETC). Electricity ismore cost effective to run than when using gasoline. The equivelent cost of elctricity is a dollar or more per gallon. Electric cars also provide the convenience of powering up at home if one's work is close enough for the battery to take them there and back. Today’s electric cars have a range of about 100 miles on a single charge. When someone comes home they plug it in and charge it for the next day. Most people do not drive far on day to day basis. “Most people would be able to benefit from a car they drive to work and charge overnight”(Truett). The average person only goes to work and back and maybe stop at a nearby store before going home. Some auto makers in the future will have solution to the charging issue. “Some future cars will have an emergency gas engine that kicks in when the battery is low”(Truett). Although these kinds of cars already exist the car will not travel very far on the battery alone which increases the need for the gasoline engine for some current cars. In the future hybrid cars will have an even smaller engine that will be used less frequently because the car will have a larger capacity battery. Another benefit that electric cars have is more horsepower and torque than petrol cars. The best current electric cars are from Tesla. “Tesla's roadster has tons of power, great handling and looks better than a Prius”(White). Tesla cars achieve multiple advantages in the way they are built by putting the battery in the middle of the car increasing its center gravity. Some auto makers might follow in the foot steps of Tesla and implement these improvements in their entry level electric cars. Most automakers will not make them as fast as a Tesla car. “Automakers invest their engineering talent in more efficient cars and new technologies rather than horsepower wars”(Espejo). Automakers will produce electric vehicles that will be comparably as fast as an average petrol car. However electric motors have many advantages that many consumers would want. In terms of power and running efficiency an electric motor produces its maximum torque and efficiency at any rpm (rotations per minute) rather than any piston engine which must speed up to reach maximum torque and running efficiency. The piston engine design requires a reciprocating piston which must change directions throughout the four stroke engine cycle and must also use engine power to turn a camshaft to open the valves to draw fuel and air into the chamber and also let exhaust out. This makes it much less efficient than an electric motor which only has one turning output shaft and nothing else but a single speed transmission. Electric cars do not waste fuel while...
