Fuel efficiency for the specified vehicle year and model refers to the distance a car can travel per unit of fuel consumed. It is typically measured in miles per gallon (MPG) in the United States. For example, a vehicle with an MPG of 30 can travel 30 miles on one gallon of gasoline.
Optimal fuel economy offers numerous advantages, including reduced fuel costs for vehicle owners and a smaller environmental footprint due to lower emissions. This attribute has historically been a significant factor for consumers when selecting a vehicle, impacting sales trends and influencing manufacturer design choices.
