The phrase identifies pre-owned vehicles offering superior fuel efficiency, measured in miles per gallon. For instance, a model achieving a high figure on the highway signifies reduced fuel consumption compared to vehicles with lower figures.
The concept is important because it allows consumers to acquire economical transportation without the price tag of a new vehicle. Selecting models with good gas mileage can substantially decrease operational costs, especially with fluctuating fuel prices. Historically, the demand for efficient vehicles has increased during periods of economic uncertainty and rising energy costs, driving interest in this category.
