23 MPG combined might initially sound modest for a modern four-cylinder, but for the 2025 Toyota Grand Highlander AWD LE/XLE 2.4L 4-cyl, it’s an acceptable figure. This substantial three-row SUV is designed to haul families, gear, and occasionally even tow, all while delivering Toyota’s renowned reliability and practicality. It’s built on a larger, wider platform than the standard Highlander, specifically to maximize interior volume, particularly in that crucial third row. The LE and XLE trims, powered by the torquey 2.4L turbocharged engine with standard all-wheel drive, are positioned as the workhorses of the lineup. They cater directly to buyers prioritizing utility, space, and all-weather capability over outright fuel miserliness, a demographic that views 23 MPG as a reasonable compromise for such a versatile family hauler. It’s delivering strong performance and space with an efficient-enough gasoline powertrain.

City and highway performance

Diving into the EPA’s breakdown, the 2025 Grand Highlander AWD LE/XLE 2.4L delivers 21 MPG in city driving and 27 MPG on the highway. These figures paint a clear picture of the vehicle’s operating characteristics. The 21 MPG city rating is indicative of a vehicle with a decent curb weight and an emphasis on low-end torque for urban stop-and-go. The 2.4L turbo engine, paired with the 8-speed automatic (S8) transmission, provides ample power for merging and navigating congested areas without feeling strained. It’s a powertrain engineered for responsiveness rather than hyper-efficiency in low-speed conditions. On the open road, the 27 MPG highway figure demonstrates the efficiency of the direct-injection turbocharged engine when it can settle into its optimal rev range. The smooth 8-speed transmission plays a significant role here, keeping engine speeds low during sustained cruising. This highway efficiency is crucial for the Grand Highlander’s target audience, families embarking on road trips with a full complement of passengers and luggage. They expect comfortable, confident highway manners and reasonable fuel consumption over long distances, and the 27 MPG delivers on that expectation for a vehicle of this size and capability.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,900 for the 2025 Toyota Grand Highlander AWD LE/XLE 2.4L. This figure is calculated based on an assumption of 15,000 miles driven per year, split between city and highway driving, using national average fuel prices. For many owners, particularly those who put significant miles on their vehicles or frequently drive in urban environments, understanding this cost is key to budgeting. While $1,900 isn’t the lowest annual fuel bill out there, it’s a competitive figure for a large, three-row SUV with standard all-wheel drive in this segment. It underscores that while 23 MPG combined isn’t class-leading for every powertrain available on the market, it represents a very manageable operational cost for buyers specifically choosing a spacious gasoline-powered three-row SUV.

Real-world expectations

In real-world driving, owners of the 2025 Grand Highlander AWD LE/XLE 2.4L should anticipate mileage ratings closely aligning with the EPA estimates. Toyota powertrains are consistent in their real-world performance versus EPA figures, and this 2.4L turbo is no exception. Factors such as aggressive driving, heavy load hauling, frequent short trips in cold weather, or extensive use of the AWD system will naturally bring figures closer to the 21 MPG city mark. Conversely, disciplined drivers with a lighter foot and a predominantly highway commute might even tick slightly above the 27 MPG highway rating. The character of this all Toyota fuel economy data engine is strong and dependable. It’s designed to perform consistently under varying conditions without dramatic fluctuations in fuel economy, making it predictable for daily use. The Grand Highlander’s mission is about practicality and reliability, and its predictable fuel efficiency contributes directly to that user experience.

How it compares

When placed against its direct gasoline-powered, three-row AWD rivals, the 2025 Grand Highlander AWD LE/XLE 2.4L holds its own. Consider the Hyundai Palisade AWD, which typically returns 21 MPG combined (19 city/24 highway) from its V6 engine. The Grand Highlander nudges ahead on highway efficiency and overall combined rating. The Kia Telluride AWD, another popular contender, largely mirrors the Palisade with 21 MPG combined (19 city/24 highway). The Honda Pilot AWD also falls into a similar range, offering 21 MPG combined (19 city/24 highway) thanks to its V6. Even the larger Chevrolet Traverse AWD is rated at 20 MPG combined (17 city/24 highway) with its 2.5L turbo-four in its most recent iteration. For detailed comparisons of the broader model range, including hybrids and larger engines, check out GRAND MPG across all years. The Grand Highlander, with its 23 MPG combined, stands out by offering superior fuel economy compared to many direct competitors, particularly those still relying on V6 engines. This is a significant advantage for buyers who want the space and utility but are conscious of rising fuel prices and their lower gas impact without committing to a full hybrid. Toyota optimized this 2.4L turbo to offer a blend of power and efficiency within its class.

Tips to maximize efficiency

Maintaining proper tire inflation is important for the Grand Highlander. Underinflated tires increase rolling resistance, forcing the powerful 2.4L engine to work harder, leading to a measurable drop in fuel economy. Refer to your owner’s manual or the sticker on the driver’s side door jamb for the recommended pressures and check them monthly.

Adopt a smooth driving style, especially when accelerating. The 2.4L turbo engine provides excellent torque, but rapid acceleration will consume more fuel. Gentle starts and anticipating traffic lights to avoid hard braking will allow the 8-speed automatic to operate most efficiently.

Minimize unnecessary weight. While the Grand Highlander is designed to haul, regularly driving around with heavy, unneeded items in the cargo area or roof racks significantly impacts fuel economy. Remove roof rack crossbars when not in use, as they create aerodynamic drag even when empty.

Use cruise control on the highway for sustained periods. The Grand Highlander’s powertrain is optimized for efficiency at steady speeds, and a consistent pace maintained by cruise control is almost always more fuel efficient than a driver attempting to hold the same speed manually.

Perform regular maintenance according to Toyota’s schedule. A clean air filter, fresh spark plugs, and properly functioning engine components ensure the 2.4L turbo engine is operating at its peak efficiency, directly translating to better fuel economy.
