17 MPG combined. That’s the headline figure for the 2024 Toyota 4Runner 4WD with its venerable 4.0L V6. It’s a number that elicits groans from some, and a shrug from others. But for the 4Runner faithful, that number represents a conscious tradeoff. They aren’t seeking ultimate fuel efficiency; they’re prioritizing ruggedness, reliability, and proven off-road capability above all else. This SUV caters to those who need a tool, not just a commuter, and who understand that serious capability often comes with a fuel consumption penalty.

City and highway performance

The 4Runner’s EPA estimates reveal a narrow spread between city and highway fuel economy. The city rating comes in at 16 MPG, reflecting the engine’s need to work harder during stop-and-go driving. The five-speed automatic transmission, while reliable, is hardly state-of-the-art when it comes to maximizing efficiency. On the open road, the 4Runner manages a marginally better 19 MPG highway. This small improvement is due to the engine operating at a more consistent speed and load, but the vehicle’s boxy shape and less-than-aerodynamic profile still take their toll. Four-wheel-drive systems often exact a minor fuel economy penalty compared to two-wheel drive versions of the same vehicle. Drivers can find 4RUNNER MPG across all years to compare different configurations.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2024 Toyota 4Runner 4WD will be $2,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and the price of gasoline in your area. Drivers who frequently engage the four-wheel-drive system, tow trailers, or spend a lot of time in heavy traffic can expect to exceed this estimate substantially.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy for the 4Runner often deviates from the official estimates, particularly for those who use it as intended. Off-road enthusiasts, overlanders, and weekend adventurers will likely see MPG figures below the combined 17 MPG rating. Factors like tire choice (knobby off-road tires have higher rolling resistance), added weight from aftermarket accessories (roof racks, bumpers, winches), and driving terrain (sand, mud, rocks) all contribute to decreased fuel efficiency. Conversely, drivers who primarily use their 4Runner for commuting on paved roads and adhere to moderate driving habits might achieve figures closer to the EPA estimates.

How it compares

Compared to its competitors, the 4Runner’s fuel economy numbers are noticeably lower. The Jeep Wrangler Unlimited with its 2.0L turbocharged four-cylinder achieves around 22 MPG combined. Even the larger Ford Bronco with its 2.3L EcoBoost engine can manage around 20 MPG combined. The aging Nissan Frontier, while recently redesigned, returns similar MPG figures to the 4Runner. The difference underscores the 4Runner’s emphasis on traditional, proven mechanicals over modern, fuel-saving technologies. This is a calculated decision by Toyota, targeting a specific buyer who values durability and simplicity over outright efficiency. Those seeking a more efficient Toyota SUV can find all Toyota fuel economy data on other models like the RAV4.

Tips to maximize efficiency

While the 4Runner isn’t known for its exceptional fuel economy, there are a few things you can do to improve your MPG. First, avoid aggressive acceleration and braking. The 4.0L V6 responds well to a gentle foot, and sudden bursts of power will significantly impact fuel consumption. Anticipate traffic conditions and maintain a steady speed whenever possible.

Ensure your tires are properly inflated. Maintaining the correct tire pressure reduces rolling resistance and improves fuel efficiency. Check your tire pressure regularly, especially before long trips, and adjust as needed according to the manufacturer’s recommendations. Also, consider using a less aggressive tire tread pattern if you primarily drive on paved roads.

Minimize unnecessary weight. Carrying extra cargo or installing heavy aftermarket accessories can negatively impact fuel economy. Remove any items you don’t need from the vehicle, and consider the weight of any modifications you’re planning. A lighter vehicle requires less energy to move, resulting in better MPG.

Consider the type of fuel you use. While the 4Runner does not require premium fuel, using higher-octane gasoline can sometimes provide a slight improvement in fuel economy, especially in warmer weather. Experiment to see if you notice a difference, but be aware that the cost of premium fuel may outweigh any potential benefits.
