The MPG ratings shown below are for a specific style (trim level) of a vehicle. Not all styles of a vehicle will get the same MPG. More importantly, the MPG you get when you drive a vehicle will vary based on a number of factors, including engine size, transmission type, tires, how many people and how much cargo are in the car, how you drive, how well you care for your car and the type of environment you drive it in.
