An 18 MPG combined rating might give some pause, but context is everything. For the 2019 Toyota 4Runner 2WD with its reliable 4.0L V6, it’s a figure accepted, even expected, by its dedicated following. This isn’t a crossover designed for maximizing fuel efficiency; it’s a body-on-frame SUV built for durability and off-road capability, traits that prioritize ruggedness over economy. Buyers choose the 4Runner knowing its limitations, appreciating its inherent toughness and legendary reliability above all else.

City and highway performance

The EPA estimates for the 2019 4Runner 2WD peg city driving at 17 MPG and highway cruising at 21 MPG. The lower city figure reflects the engine’s workload in stop-and-go traffic, exacerbated by the vehicle’s weight and traditional automatic transmission. The highway number is more palatable, but still far from class-leading. This split performance echoes the 4Runner’s intended duality: capable enough for urban environments, but genuinely excelling when the pavement ends. The five-speed automatic transmission, while proven and reliable, lags behind modern 8- and 10-speed units in optimizing fuel consumption, particularly at higher speeds.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,450 for the 2019 Toyota 4Runner 2WD. This figure is based on driving 15,000 miles per year, with a mix of city and highway driving conditions. The calculation assumes national average fuel prices; fluctuations in gasoline costs will naturally impact the actual amount spent. For those considering a used 4Runner, factoring in this annual expense is crucial, as it represents a significant ongoing cost of ownership.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often deviates based on driving style, terrain, and vehicle load. Aggressive acceleration, heavy braking, and carrying extra cargo will all negatively impact MPG. Smooth driving, consistent speeds, and minimizing unnecessary weight can nudge the numbers closer to the EPA estimates. Owners who primarily use their 4Runner for commuting in congested areas are likely to see numbers closer to the 17 MPG city rating.

Those who frequently embark on longer highway trips might achieve figures closer to 21 MPG, but sustained speeds above 70 mph will take their toll.

How it compares

Compared to its competitors, the 2019 4Runner 2WD’s fuel economy is demonstrably lower. A similarly-sized 2019 Jeep Grand Cherokee with its base 3.6L V6 and rear-wheel drive configuration achieves a more palatable 19 MPG combined. Even the more powerful V8 Grand Cherokee manages around 17 MPG combined in 4WD configuration, only 1 MPG fewer despite the significant power increase. A 2019 Honda Passport, with its focus on on-road comfort and efficiency, delivers a significantly better 22 MPG combined.

This comparison is important; the 4Runner buyer is consciously choosing a vehicle prioritizing different attributes than outright fuel economy. If MPG is important, numerous other options exist. For those seeking a rugged, body-on-frame SUV known for its longevity, the 4Runner’s drawbacks in fuel economy are a calculated trade-off.

Tips to maximize efficiency

Gentle acceleration and consistent speeds are key to squeezing out every last mile per gallon from the 4Runner’s V6. Avoid aggressive starts and hard braking, as these actions consume more fuel. Anticipating traffic flow and maintaining a steady pace will reduce the engine’s workload and improve overall efficiency.

Ensure that your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, leading to decreased fuel economy. Regularly check and adjust tire pressure, especially before long trips, as even a small difference can impact MPG.

Reduce unnecessary weight by removing any items you aren’t actively using. Extra cargo in the vehicle adds strain on the engine, forcing it to work harder and consume more fuel. Decluttering the interior and removing items from the roof rack (if equipped) can make a noticeable difference.

Consider using cruise control on long highway stretches. This helps to maintain a consistent speed, minimizing fluctuations in throttle input and optimizing fuel consumption. However, disengage cruise control when driving in hilly terrain or during inclement weather for better control.
