24 MPG combined is the headline figure for the 2025 Toyota Grand Highlander LE/XLE 2.4L 4-cylinder, an entirely respectable number for a three-row SUV designed specifically to maximize interior volume and family utility. This isn’t a lithe, nimble crossover, it’s a dedicated hauler built on a longer wheelbase, offering genuine comfort for seven or eight passengers and ample cargo space behind the third row. The buyer considering this Grand Highlander prioritizes practicality, Toyota’s legendary reliability, and a generous feature set at a good price, and for them, this fuel economy represents a sensible balance rather than an aspiration for outright efficiency.

City and highway performance

Looking at the EPA figures, the Grand Highlander delivers 21 MPG in city driving and 28 MPG on the highway. The city number is particularly noteworthy given the vehicle’s size and curb weight. Stop-and-go traffic is inherently inefficient, and maintaining over 20 MPG in urban environments shows the calibration of the 2.4L turbocharged engine and the smooth operation of the 8-speed automatic transmission. This powertrain manages to provide adequate low-end torque for confident acceleration from a standstill, a crucial factor for the daily grind of school runs and errands, without severely penalizing fuel consumption. On the highway, 28 MPG is a strong showing for a large SUV. The Grand Highlander tracks quietly at speed, and the powertrain settles into a relaxed cruise, using its higher gears to keep engine RPMs low, consequently conserving fuel. This strong highway performance is a significant selling point for families who frequently embark on longer road trips, where the extended range between fill-ups translates directly into less inconvenience.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,800 for the 2025 Toyota Grand Highlander LE/XLE 2.4L 4-cylinder. This figure is calculated based on an average of 15,000 miles driven per year, split between city and highway conditions, and using national average fuel prices. It serves as a useful benchmark for budgeting and understanding the ongoing running costs of the vehicle. For families seeking dependable, long-term ownership, this predictable and relatively modest annual expenditure reinforces the Grand Highlander’s value. It’s a transparent breakdown that allows buyers to factor fuel directly into their financial planning, rather than encountering unexpected fluctuations.

Real-world expectations

In real-world driving, owners of the 2025 Grand Highlander 2.4L should expect to achieve numbers very close to the official EPA ratings. Toyota powertrains are generally known for their consistency between laboratory tests and actual use, due to conservative calibration and reliable engineering. That said, individual driving habits invariably influence fuel economy. Aggressive acceleration, frequent hard braking, and sustained high-speed driving will naturally push numbers lower, particularly in city driving where the turbocharger might be working harder. Conversely, smooth throttle inputs, anticipating traffic flow, and maintaining steady highway speeds can even nudge MPG slightly above the EPA estimates. The Grand Highlander’s large frontal area and weight mean that aerodynamic drag and inertia play a significant role, so maintaining momentum efficiently is key to maximizing its potential. Families on long, steady interstate cruising will likely see the 28 MPG highway figure come to life consistently.

How it compares

The 2025 Grand Highlander 2.4L enters a highly competitive segment, and its 24 MPG combined places it favorably against many key rivals, especially when considering its internal combustion primary focus. The Kia Telluride, a popular choice for similar buyers, offers a 3.8L V6 delivering 21 MPG combined (20 city/26 highway) in its FWD configuration. The Honda Pilot, another direct competitor, with its 3.5L V6, is rated at 22 MPG combined (19 city/27 highway), making the Grand Highlander the more efficient choice here. Even within its own family, it carves a specific niche. For those interested in exploring GRAND MPG across all years, it becomes clear the Grand Highlander is designed for broader appeal than its smaller sibling, the Highlander, which prioritizes a slightly more compact footprint. While some competitors offer hybrid versions that surpass the Grand Highlander’s efficiency, like the Grand Highlander Hybrid itself or the Pacifica Hybrid, those come with a higher purchase price and a different driving character. The 2.4L Grand Highlander appeals to the buyer who wants the familiar, proven fuel delivery and operation of a conventional gasoline engine, knowing they are still getting class-leading efficiency for that powertrain type. This buyer isn’t necessarily seeking an electrified solution, but rather the best possible MPG from a traditional, large family SUV.

Tips to maximize efficiency

To get the most out of your Grand Highlander’s 2.4L engine, maintaining consistent throttle input is crucial. Avoid sharp acceleration and sudden braking, as the turbocharged engine works best when operating within its efficiency sweet spot, which smooth driving facilitates. Anticipate traffic and road conditions to minimize the need for heavy braking, allowing the vehicle’s momentum to carry it as much as possible.

Regular maintenance is a non-negotiable aspect of good fuel economy for any vehicle, and the Grand Highlander is no exception. Ensure your tires are always inflated to the manufacturer’s recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel unnecessarily.

Consider lightening the load. The Grand Highlander boasts cavernous cargo space, but carrying unnecessary weight, even seemingly small items, adds up over time. Remove roof racks, cargo boxes, or heavy items from the trunk if they aren’t needed for your current trip, reducing both aerodynamic drag and overall mass.

For those living in hilly areas or frequently traversing inclines, try to minimize the number of hard climbs. The 2.4L turbo engine, while capable, will consume more fuel under sustained high load. Where possible, plan routes that offer gentler gradients or allow for a more consistent speed.

Keep your powertrain running smoothly by adhering to the recommended service intervals outlined in your owner’s manual. Clean air filters and fresh engine oil contribute significantly to optimal engine performance and efficiency. For more insights on efficient driving and a complete look at all Toyota fuel economy data, regular checks are invaluable.
