The 2020 Toyota Highlander 3.5L V6 gets 23 MPG combined, which is competent but not groundbreaking in the midsize, three-row SUV segment. Highlander buyers typically prioritize reliability, resale value, and family-friendly features over outright fuel efficiency, so they find this acceptable in exchange for the vehicle’s other strengths. This Highlander appeals to pragmatic families who need space and dependability, understanding they’ll be compromising on gas station visits.

City and highway performance

The EPA estimates of 20 MPG city and 28 MPG highway for the 2020 Toyota Highlander with the 3.5L V6 and eight-speed automatic represent the vehicle’s performance under standardized testing conditions. In city driving, the Highlander’s fuel consumption reflects the stop-and-go nature of urban environments where frequent acceleration and idling impact mileage. On the highway, the 28 MPG figure is attainable during steady cruising at moderate speeds, showcasing the engine’s efficiency when not under heavy load. The eight-speed automatic transmission contributes by keeping the engine in its optimal rev range. These numbers provide a solid baseline for estimating fuel costs, but real-world results depend on individual driving habits and environmental factors.

Annual fuel cost

The Environmental Protection Agency (EPA) estimates the annual fuel cost for the 2020 Toyota Highlander 3.5L V6 at $1,900. This is calculated based on driving 15,000 miles per year, with a projection of 55% city driving and 45% highway driving. It also assumes national average fuel prices at the time of calculation. This $1,900 figure is an approximation, and your actual fuel expenses may vary. Drivers who primarily drive in the city, or those with a heavier foot, will likely exceed this estimate. On the other hand, those who do mostly highway miles and practice fuel-efficient driving could spend less. This figure is for the front-wheel drive model; All-Wheel Drive variants will likely cost more annually.

Real-world expectations

While the EPA provides a standardized benchmark, your personal experience with the Highlander’s fuel economy can differ. Expect to see numbers closer to the stated EPA figures if you frequently drive on the highway and use cruise control. Hilly terrain, carrying heavy loads, or frequent short trips will all negatively affect your observed MPG. Aggressive acceleration and hard braking are major culprits that can quickly drop fuel efficiency below the EPA estimates. Weather also plays a role; cold temperatures can reduce fuel economy because of denser air and the engine working harder to reach its best operating temperature. Tire pressure also affects a vehicle’s efficiency. Be sure to consult HIGHLANDER MPG across all years of production.

How it compares

The 2020 Toyota Highlander’s 23 MPG combined compares to its competitors in interesting ways. The Honda Pilot, another popular three-row SUV, achieves around 22 MPG combined with its V6 engine. The Ford Explorer, depending on the engine, can range from 21-24 MPG combined. The Nissan Pathfinder lands somewhere in between, around 23 MPG. However, some competitors offer hybrid options that significantly surpass the Highlander’s fuel economy. For example, the Toyota Highlander Hybrid itself achieves around 36 MPG combined, presenting a substantial improvement for those wanting less gas. The Kia Telluride, a newer entrant, typically scores around 21 MPG. The Highlander’s numbers are adequate, but not class-leading. Buyers selecting this vehicle are often willing to forgo top-tier fuel economy for Toyota’s reputation for longevity and strong resale value. Consult all Toyota fuel economy data.

Tips to maximize efficiency

Gentle acceleration is key to getting every mile out of a gallon of gas. Avoid sudden bursts of speed and allow the Highlander to gradually build momentum. The 3.5L V6 is responsive, but smoothly modulating the throttle will keep you out of the lower gears and preserve fuel. Anticipate traffic flow and time your acceleration accordingly; avoid unnecessary braking that wastes kinetic energy.

Consistent tire pressure, as stipulated on the tire placard, is essential for good fuel economy. Underinflated tires increase rolling resistance and drag down your MPG. Check your tire pressure regularly, especially when the temperature changes, and adjust as needed. Properly inflated tires also improve handling and extend tire life.

Minimize your use of accessories like air conditioning, especially during short trips. AC compressors put a significant strain on the engine and reduce fuel efficiency. When possible, use the ventilation system or open windows at lower speeds. Keep your vents and filters clean.

Avoid unnecessary idling. If you anticipate waiting for more than a minute or two, it’s more fuel-efficient to turn off the engine. Modern engines are designed to restart quickly and reliably, and prolonged idling consumes fuel without moving the vehicle. This is especially important in urban environments.

Reduce weight inside the vehicle. Extra cargo adds load to the engine, requiring more fuel to maintain speed. Remove any unnecessary items from the trunk or cargo area that are not essential for your journey. A lighter vehicle requires less energy to accelerate and maintain speed, improving fuel efficiency.
