Fuel efficiency, specifically as it pertains to a minivan manufactured by Toyota in 2014 with the model name Sienna, is the distance a vehicle can travel per unit of fuel consumed. For instance, this measurement reveals how many miles the vehicle can travel on one gallon of gasoline under varying driving conditions.
Understanding the fuel consumption characteristics of this vehicle is crucial for prospective buyers and current owners. Knowledge of these characteristics aids in budgeting for fuel costs, comparing the vehicle’s economy with competitors, and making informed decisions about vehicle usage and maintenance. Historically, this model year represented a point in automotive design where fuel efficiency was becoming increasingly prioritized, influenced by both consumer demand and regulatory standards.
