22 MPG combined is a reasonable figure for the 2024 Toyota Grand Highlander AWD Limited or Platinum with the 2.4L turbocharged four-cylinder. It’s a number that reflects the vehicle’s mission: hauling families and their gear in comfort and safety, regardless of weather. This Grand Highlander isn’t trying to be a fuel-sipping hybrid; it’s answering a different need. It’s for those who need three rows, appreciate Toyota’s reputation for reliability, and prioritize space and practicality over outright efficiency.

City and highway performance

The EPA estimates put the Grand Highlander AWD Limited/Platinum at 20 MPG in the city and 26 MPG on the highway. The lower city figure is predictable, given the stop-and-go driving that characterizes urban environments. The turbocharger needs to spool up more often from a standstill, and the eight-speed automatic transmission goes through more shifts, both actions consuming fuel. The 26 MPG highway rating is more palatable, suggesting that on long road trips, the Grand Highlander can maintain a decent level of efficiency when cruising at a steady speed. The turbocharged engine, while not a hybrid, provides adequate power without needing to be pushed too hard, a plus for highway economy. These numbers are not going to excite any Prius owners, but they are suitable for the practical buyer Toyota is targeting with this SUV.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Toyota Grand Highlander AWD Limited/Platinum 2.4L to be $2,000. This figure is based on driving 15,000 miles per year and using the national average fuel price. While individual fuel costs will vary based on local fuel prices and driving habits, this provides a benchmark figure against which to compare other vehicles or to estimate your own potential expenses. Consider that if you drive substantially more or less than 15,000 miles annually, or if fuel prices in your area are significantly higher or lower than the national average, your actual fuel costs will differ.

Real-world expectations

Keep in mind that EPA estimates are derived from controlled testing. Real-world fuel economy may vary based on driving style, traffic conditions, weather, and even tire pressure. Aggressive acceleration and hard braking will undoubtedly lower your MPG. Carrying heavy loads, such as a full complement of passengers and luggage, will also impact fuel efficiency. Regular maintenance, like ensuring proper tire inflation and timely oil changes, can help maintain optimal fuel economy. It’s realistic to expect some deviation from the EPA numbers, so plan accordingly.

How it compares

Compared to other three-row SUVs with all-wheel drive, the Grand Highlander’s fuel economy sits in the middle to slightly below average. The Honda Pilot TrailSport, another popular choice, achieves an EPA combined rating of 20 MPG. A Kia Telluride AWD comes in around 20 MPG combined as well. The Ford Explorer, even with its EcoBoost engine, often lands in the same ballpark of low- to mid-20s for combined MPG, depending on the specific configuration. If fuel economy is a top priority, buyers might consider the hybrid versions of these vehicles if available, or even consider a minivan like the Toyota Sienna, which achieves far greater fuel effciency and can achieve close to 35 MPG combined. But those alternatives have different strengths elsewhere and are a different type of vehicle, so the trade-offs are not equal. For those seeking all Toyota fuel economy data in the realm of large SUVs with conventional gasoline engines, the Grand Highlander represents a fair balance of size, capability, and relative efficiency.

Tips to maximize efficiency

Avoid aggressive acceleration. The 2.4L turbo engine delivers its power smoothly, so there’s little need to stomp on the accelerator. Gradual acceleration will conserve fuel, especially in city driving. The engine is strong enough to deliver adequate performance without being pushed, so drive accordingly and focus on smooth progress through traffic.

Maintain proper tire inflation. Under-inflated tires create more rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker inside the driver’s side door. This simple step can make a noticeable difference over time.

Minimize idling. Idling consumes fuel without covering any distance. If you’re stopped for more than a minute or two, turn off the engine. The Grand Highlander restarts quickly and a brief moment of restarting is better than prolonged idling. This is particularly important in city traffic.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long trips. Avoid frequently accelerating and decelerating, as this wastes fuel. Set your desired speed and let the system do the work.

Consider using lighter weight oil at your next oil change. It can improve fuel economy slightly since the parts inside your engine won’t have to work as hard. A Toyota service advisor know the weight requirements of GRAND MPG across all years and can advise on best practices.
