18 MPG combined. That’s the official EPA figure for the 2017 Toyota 4Runner 4WD with its 4.0L V6. Let’s be honest: it’s not going to win any fuel efficiency awards. But for the 4Runner faithful, this number isn’t a dealbreaker. It’s almost a badge of honor. This is a body-on-frame SUV designed for strong capability, for tackling trails and hauling gear. Its priority is not sipping fuel; it’s conquering obstacles. This is for the buyer who values dependability and off-road prowess above all else, someone who understands that compromises must be made.

City and highway performance

The EPA estimates reflect the reality of the 4Runner’s aging powertrain. Ratings of 17 MPG in the city and 20 MPG on the highway reveal that the 4.0L V6, while reliable, leans heavily on old-school technology. The five-speed automatic transmission, while smooth, lacks the extra ratios found in modern transmissions that help optimize fuel use. City driving, with its stop-and-go nature and frequent acceleration, tends to punish the 4Runner due to its weight and somewhat thirsty engine. Highway driving offers a slight improvement, but the vehicle’s aerodynamics (or lack thereof) prevent it from achieving significantly better results.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Toyota 4Runner 4WD at exactly $2,450. This figure is based on driving 15,000 miles per year, using the EPA’s fuel economy estimates, and assuming national average fuel prices. It’s important to remember that this is an estimate. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and the specific conditions in which you operate the vehicle, but it gives you an idea of what to expect.

Real-world expectations

Don’t expect to consistently match, much less exceed, the EPA estimates. Many 4Runner owners report slightly lower figures, particularly those who frequently engage the four-wheel-drive system or spend a lot of time in city traffic. Aggressive driving, carrying heavy loads, or using roof racks will also negatively impact fuel economy. However, a mindful driver who sticks to the highway and avoids sudden acceleration can likely achieve numbers close to the EPA’s estimates. The key is to be aware of the 4Runner’s limitations and adapt your driving style accordingly.

How it compares

Compared to other SUVs with similar capabilities, the 4Runner’s fuel economy lags behind. The Jeep Grand Cherokee offers better fuel efficiency, with the 4×4 V6 model achieving around 21 MPG combined. Even the more modern Ford Bronco, with its 2.3L EcoBoost engine, delivers significantly better numbers, easily exceeding 20 MPG combined in its four-wheel-drive configuration. The Chevrolet Tahoe, with its larger V8 and more advanced transmission, surprisingly gets similar, and sometimes better, fuel economy in real-world testing. For buyers prioritizing fuel efficiency above all else, there are definitely better options on the market. But those options generally sacrifice the outright off-road capability and legendary reliability that the 4Runner provides. For more information, see all Toyota fuel economy data.

Tips to maximize efficiency

Ensure your tires are properly inflated. Maintaining the correct tire pressure reduces rolling resistance, which improves fuel economy. This is especially critical for a heavy vehicle like the 4Runner. Check your tire pressure regularly, using the recommended PSI found on the driver’s side door jamb.

Avoid aggressive acceleration and braking. The 4Runner’s V6 engine responds well to smooth, gradual inputs. Jackrabbit starts and hard braking waste fuel. Anticipate traffic flow and maintain a steady speed whenever possible.

Keep your vehicle properly maintained. Regular maintenance, including oil changes, air filter replacements, and spark plug replacements, ensures that the engine is running efficiently. A poorly maintained engine will consume more fuel.

Reduce unnecessary weight. Remove any unnecessary cargo from the vehicle. Extra weight puts a strain on the engine and reduces fuel economy, especially when off-roading. Consider removing roof racks or cargo carriers when not in use, as they create aerodynamic drag.

Plan your trips strategically. Combine errands into a single trip to minimize cold starts, which are particularly fuel-intensive. Avoid peak traffic hours when possible, as stop-and-go driving significantly reduces fuel economy.
