Cars do not waste gas they burn it. I assume you are asking what car gets the best mileage but you have an unorthodox way of asking the question. You also do not say what class of vehicle you're referring to or if you are asking about a hybrid or non-hybrid. The best non-hybrid is the Honda Civic at 41 miles per gallon. The best hybrid is the Toyota Prius at 51 miles per gallon.
Much better if we will just use electricity for cars since you will recharge it instead of using gas that produces gas that can harm us all especially the environment.
Pretty much any 4 cylinder, but don't get a hybrid they cost you a lot more money.

Look for a car that will suit you well. Having a expensive car doesn't make you cool. Buy a car, that you think, that will last you long enough and has 3.5L of gas. You less litters of gas, the less payment on gas.
A bus isn't a car, because cars need less gas and buses need LOTS OF MORE GAS
no, it wastes gas by driving fast.
To answer this question we need to know what your car's gas mileage [mpg] is. My hybrid will use less gas than your SUV to drive the same distance - therefore my cost will be less. That's why we need to know the rate of gas consumption. It will vary from car to car.
