Fuel efficiency in a Toyota 4Runner refers to the number of miles the vehicle can travel on a gallon of gasoline. For example, a 4Runner with a rating of 17 miles per gallon in the city indicates that it can, on average, travel 17 miles within an urban setting using one gallon of fuel. This metric is a key factor for owners concerned about running costs.
Understanding the fuel consumption of a vehicle such as the Toyota 4Runner is vital for budgeting and assessing long-term ownership expenses. Historical trends in fuel efficiency have influenced automotive design, leading to innovations aimed at reducing consumption. Improved fuel economy can translate to lower expenses over the lifespan of the vehicle and a reduced environmental impact.
