What is the average MPG for a Toyota 4Runner?
The average MPG for a Toyota 4Runner varies depending on the model year and trim level. However, based on data from the United States Environmental Protection Agency (EPA), the average MPG for a Toyota 4Runner is around 17-18 miles per gallon in the city and 20-21 miles per gallon on the highway. Some model years and trims may have slightly better or worse MPG, but this gives you a general idea of what to expect.
It’s also worth noting that actual MPG may vary depending on several factors, including driving habits, road conditions, and weather. Additionally, some owners have reported achieving better MPG than the EPA estimates, so it’s possible to get better fuel economy with careful driving and maintenance.
Which year 4Runner has the best MPG?
The 2006 Toyota 4Runner has the best MPG, with an estimated 17 miles per gallon in the city and 21 miles per gallon on the highway. This is due to its smaller engine and lighter weight compared to newer models. Additionally, the 2006 model year was a transitional year for the 4Runner, and it has a more aerodynamic design that helps improve fuel efficiency.
