24 MPG combined reflects the balance in the 2024 Toyota Grand Highlander LE and XLE trims with the 2.4L four-cylinder engine. This isn’t a Prius, and no one expects it to be. But for families needing the large space of a three-row SUV without resorting to a truck-based large vehicle, and who aren’t prioritizing maximum towing capability requiring a V6 or hybrid powertrain, those 24 miles per gallon are an acceptable trade-off for functionality and Toyota’s well-earned reputation for reliability.

City and highway performance

The EPA estimates the Grand Highlander LE/XLE at 21 MPG in the city and 28 MPG on the highway. The city figure reflects stop-and-go traffic, where the large SUV’s weight and the engine’s need to overcome inertia affect fuel economy. However, the highway MPG is more respectable, showcasing the engine’s ability when cruising at a steady speed. The eight-speed automatic transmission helps in both scenarios, keeping the engine in its optimal power band. The differences between city and highway demonstrate that careful driving habits can improve fuel economy, especially when avoiding excessive acceleration in urban settings.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 Toyota Grand Highlander LE/XLE 2.4L is $1,800. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a helpful benchmark for budgeting, but know that your actual fuel costs will vary based on your driving habits, the type of driving you do, and local fuel prices. If you mostly drive in the city, or accelerate quickly, expect to spend more. If you do a lot of highway driving, you may spend less.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy is always dependent on individual driving habits and conditions. Grand Highlander owners who frequently haul passengers and cargo, or who live in hilly areas, may see figures closer to the 21 MPG city rating. Those who primarily use the vehicle for highway commuting and practice smooth acceleration and braking are more likely to approach, or even slightly exceed, the 28 MPG highway estimate. A realistic average for most owners will likely fall somewhere between 22 and 26 MPG. Also, ensure you are using the correct fuel grade for best performance. Consult your owner’s manual for recommendations.

How it compares

The Grand Highlander’s fuel economy is competitive with its competitors. The Honda Pilot, with its standard V6 engine, achieves around 22 MPG combined. The Kia Telluride, another popular three-row SUV, delivers similar fuel economy figures. The Ford Explorer, depending on the engine configuration, can range from slightly better to worse in terms of MPG. The Nissan Pathfinder lands in a similar MPG range.

The key distinguishing feature is the existence of the Grand Highlander Hybrid, which significantly boosts fuel economy. Those prioritizing fuel efficiency above all else within the Grand Highlander family should consider that model. However, for buyers focused on the lower purchase price of the LE or XLE 2.4L models, and who don’t need the added power or complexity of a hybrid system, the standard engine’s fuel economy is competitive within the non-hybrid three-row SUV segment.

Tips to Maximize Efficiency

Avoid aggressive acceleration and braking. The Grand Highlander is a large vehicle, and rapid changes in speed require significant energy. Smooth, gradual acceleration and anticipating traffic conditions will help conserve fuel. Adjustments to driving style can improve fuel economy.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended level, found on the tire placard on the driver’s side doorjamb.

Minimize idling. Idling consumes fuel without moving the vehicle. If you anticipate being stopped for more than a minute, turn off the engine. Modern vehicles are designed to restart quickly and efficiently.

Reduce unnecessary weight. Carrying excessive cargo adds weight to the vehicle, which reduces fuel economy. Remove any unnecessary items from the vehicle, especially heavy ones, to improve efficiency.

Plan your trips efficiently and avoid peak traffic. Combining errands into a single trip minimizes cold starts, which are less fuel-efficient. Also, try to drive during off-peak hours to avoid stop-and-go conditions that drain fuel. Good route planning is key.
