The efficiency with which a 2012 Toyota Sienna converts gasoline into motion is a key characteristic for potential buyers. This metric, typically measured in miles per gallon (MPG), reflects the distance the vehicle can travel on a single gallon of fuel. For example, a Sienna with a rating of 20 MPG can travel 20 miles on one gallon of gasoline.
Understanding this aspect is critical for assessing the long-term operating costs associated with vehicle ownership. Improved numbers translate to lower fuel expenses over the lifespan of the minivan. Historically, fuel efficiency has become an increasingly important factor as gasoline prices fluctuate and environmental awareness grows.
