The old EPA for this car is 17city/22highway/19combined and the new (revised) EPA is 15city/20highway/17combined. Which is more accurate? It says the new EPA average is tested by using faster speed and acceleration, air conditioner use, and colder outside temperatures. The car I am asking about is low mileage and pretty much like new mechanically and cosmetically. I don't put the car through heavy acceleration and the fastest I drive is the speed limit (usually less) and I rarely use the air conditioning. Judging by what I said do you think the new EPA or the old EPA is most accurate for me?
