Fuel efficiency, specifically measured in miles per gallon (mpg), represents a critical factor for prospective minivan purchasers. The 2024 Toyota Sienna’s fuel economy reflects the distance a vehicle can travel on a single gallon of gasoline. It serves as a primary indicator of operational cost. For instance, a vehicle with a high mpg rating requires less fuel to cover the same distance compared to one with a lower rating.
Understanding a vehicle’s fuel consumption provides numerous advantages. Lower fuel consumption translates directly to reduced expenditures at the pump. Furthermore, improved efficiency often correlates with decreased emissions, contributing to a lessened environmental impact. Historically, consumer demand for vehicles prioritizing fuel conservation has influenced automotive design and technological advancements.
