"Necessity is the mother of invention," is the saying you're looking for.

I don't know how concerned you are with content, but the essay at the moment lacks depth. You have a list of facts about cars, written in paragraph form. A more interesting essay might have analyzed these facts to determine whether the benefits mentioned in the first half outweighed the disadvantages mentioned in the second half.

Of course, you may just be writing to practice grammar and style, in which case, you needn't worry about content much at all.

First tip -- the punctuation should be the same as it is in my comments; periods, colons, semi-colons, and commas have no space before them, and one space after them. This is really quite important, as essays with extra/missing spaces can be difficult for others to read, especially in the latter case.

Second tip -- verbs need to match the noun in number, and they need to be conjugated to reflect the tense you intend. For instance:

"Cars is created to give better mileage that contribute to save money" is doubly wrong. First, "cars" is plural. "Is" is singular. It would have to be either "Cars are" or "cars were." Second, you're talking about something that happened in the past. "is" and "are" are present tense. "Was" and "were" are past tense. So, in the case, the sentence should begin "cars were," so that the verb is both plural and past.

I'm sure other contributors will point out other things you can fix . . .

10x for your advice i'll do my best to be good in writting ,i'll follow your advice

Sean's advise is very sound. Follow it. Here's my advice: Don't use a translation devise when searching for the word you want, as this will often lead to strange word choices. Try to say what you mean using the words you know. If you must look for a word, use a dictionary and read the definitions carefully before deciding which word (and which form of the word) to use.
