19 MPG combined is the reality for owners of the 2015 Toyota 4Runner 2WD with the 4.0L V6. No one buys this 4Runner for its fuel efficiency. People buy it for its reliable build, its proven off-road capability (even in 2WD guise), and its truck-based durability. The fuel bill is simply a cost for those who value these qualities.

City and highway performance

The EPA estimates the 2015 4Runner 2WD at 17 MPG in the city and 22 MPG on the highway. These figures are about the inefficiencies of a naturally aspirated 4.0L V6 with a five-speed automatic transmission hauling a vehicle that weighs over 4,400 pounds. The transmission is geared for acceleration, highway cruising, and off-road driving (in the 4×4 models), but fuel efficiency wasn’t a priority. The highway figure is a best-case scenario, achievable on long, flat stretches of road at steady speeds. Aggressive acceleration or hilly terrain will decrease that number.

Annual fuel cost

The EPA estimates the annual fuel cost for this 4Runner is $2,300. This is based on driving 15,000 miles per year and using national average fuel prices, which change. Your cost will vary depending on how many miles you drive, the type of driving you do, and the price of gasoline in your area. Drivers who spend more time in city traffic or frequently tow will likely exceed this estimate, while those who primarily use their 4Runner for highway commuting may see slightly lower costs.

Real-world expectations

EPA figures provide a baseline, and real-world fuel economy often differs. 4Runner owners report averaging around 16-20 MPG in mixed driving conditions. Expect figures closer to the lower end of that range if you drive aggressively or tow with the 4Runner. Careful drivers who prioritize fuel efficiency and drive mostly on the highway might achieve numbers closer to the EPA estimates, or even slightly above. Checking websites such as Fuelly which collect data from drivers can give a broader picture of what to expect from 4Runner MPG across all years.

How it compares

The 2015 4Runner lags behind in fuel efficiency compared to other mid-size SUVs of its time. The 2015 Jeep Grand Cherokee 2WD with its 3.6L V6 gets an EPA-estimated 19 MPG city and 26 MPG highway. The V8 version in some trims matches the 4Runner’s combined number. A 2015 Nissan Murano achieves 21 MPG city/28 MPG highway. These fuel economy numbers reflect the Grand Cherokee and Murano’s car-based platforms and more modern engine and transmission technologies. These alternatives don’t offer the same level of off-road capability or long-term durability. The 4Runner also differs from alternatives due to its full frame, rather than a typical unibody. The 4Runner customer isn’t cross-shopping against that Murano buyer, they’re willing to accept lower fuel economy for the 4Runner’s unique strengths and traditional design.

Tips to maximize efficiency

Avoid aggressive acceleration. The 4.0L V6 is capable, but stomping on the gas pedal burns fuel. Gently accelerate and maintain a steady speed.

Properly maintain your tires. Inflate your tires to the recommended pressure, which is on the sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which reduces fuel economy. Tire choice matters; a more aggressive off-road tire decreases MPG on pavement.

Minimize idling. Idling wastes fuel. If you’re stopped for more than a minute, turn off the engine. Modern starters are designed to handle frequent starts and stops.

Reduce unnecessary weight. The 4Runner is heavy, so avoid carrying extra cargo. Remove items from the cargo area that you don’t need regularly. Even small amounts of extra weight can impact fuel economy, especially in city driving. Knowing all Toyota fuel economy data shows just how much weight can affect the MPG.
