23 MPG combined for the 2026 Toyota Grand Highlander AWD LE/XLE 2.4L 4-cyl shows a deliberate engineering choice for a vehicle that prioritizes family functionality and all-weather confidence over outright speed or ultra-luxury pretense. This substantial three-row SUV, powered by a turbocharged four-cylinder, is designed for the active family or individual who needs genuine space, a strong AWD system for varying conditions, and the undeniable reliability of a Toyota. They’re buying into a practical solution for daily life, weekend excursions, and long-haul road trips. 23 MPG represents a sensible balance between capability and operating cost for a vehicle of this size and mission.

City and highway performance

The EPA rates the 2026 Grand Highlander AWD LE/XLE at 21 MPG in the city and 27 MPG on the highway. That 21 MPG in city driving is a realistic figure when contending with school drop-offs, grocery runs, and stop-and-go commutes. This isn’t a small vehicle; its mass and the demands of urban traffic naturally impact efficiency. However, the 2.4L turbocharged engine, paired with an automatic (S8) transmission, manages this admirably, offering sufficient low-end torque to move the Grand Highlander purposefully without feeling strained. The 27 MPG highway rating is where the powertrain truly settles in. On long stretches of open road, with the engine humming along at cruising speeds, the Grand Highlander delivers a commendable performance for a large, three-row SUV. It’s a comfortable, quiet cruiser, and that 27 MPG number reassures owners that long family vacations won’t necessarily break the bank at every fuel stop.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,900 for the 2026 Toyota Grand Highlander AWD LE/XLE 2.4L 4-cyl. This figure is based on driving 15,000 miles per year, with 45% of those miles in city driving and 55% on the highway, and assumes national average fuel prices. For many Grand Highlander owners, this $1,900 represents a predictable and manageable line item in their annual budget. This calculation takes the guesswork out of estimating long-term running costs, providing a clear financial picture for families who are often meticulously planning expenditures. This is a vehicle purchased for its utility and dependability, and its annual fuel cost aligns with those pragmatic considerations.

Real-world expectations

Our experience with vehicles in this class suggests that achieving the EPA’s combined 23 MPG is quite attainable for the Grand Highlander AWD LE/XLE, provided driving habits are reasonable. Aggressive acceleration and frequent hard braking will, as always, degrade efficiency. However, the 2.4L turbo, while offering decent power, doesn’t inherently encourage a lead foot. Its character is more about smooth, confident propulsion rather than exhilarating bursts. Drivers hauling a full complement of passengers and cargo, or those frequently navigating hilly terrain, might see figures marginally below the EPA numbers. Conversely, those with a light foot and predominantly highway commutes could comfortably exceed the 27 MPG highway rating. The Grand Highlander’s size and AWD system are constants, so acknowledging the physical realities of moving a large family vehicle efficiently is key to managing expectations.

How it compares

The 2026 Grand Highlander AWD LE/XLE sits in a fiercely competitive segment, but its 23 MPG combined positions it well. Consider some key rivals, the Honda Pilot AWD, a perennial bestseller, typically lands around 21 MPG combined. The Kia Telluride AWD, another strong contender, also hovers around 21 MPG combined. Even the Mazda CX-90 AWD, with its mild-hybrid inline-six, in certain configurations, might offer similar or slightly better figures, but often with a different price point and driving dynamic. The Grand Highlander’s closest internal competitor might be the standard Highlander Hybrid, which achieves significantly higher MPGs, but sacrifices some interior volume and overall ruggedness. For a mainstream, non-hybrid, three-row SUV with substantial space and standard AWD, the Grand Highlander’s 23 MPG is highly competitive, especially when evaluating its mission of family utility and all-weather capability.

Tips to maximize efficiency

Maintaining consistent tire pressure is fundamental. The Grand Highlander’s all-wheel drive and weight demand correctly inflated tires for optimal rolling resistance, directly impacting your fuel economy. Check them monthly, especially as seasons change.

Employ smooth driving techniques. The 2.4L turbo engine, combined with the automatic (S8) transmission, is designed for efficiency at steady speeds. Avoid rapid acceleration and hard braking, anticipate traffic and coast when possible to let the powertrain work efficiently.

Use cruise control on the highway. Setting the adaptive cruise control (if equipped) on open roads helps maintain a steady speed, preventing unnecessary speed fluctuations that consume extra fuel, thereby helping you achieve that 27 MPG highway figure.

Limit unnecessary weight. While the Grand Highlander is built to carry people and cargo, routinely hauling heavy, non-essential items like tools or sports equipment adds to the vehicle’s mass, requiring more energy to move and reducing efficiency. Clear out the trunk and third row when not in use.

Perform regular maintenance. Adhering to Toyota’s recommended service schedule, particularly oil changes, air filter replacements, and spark plug checks, ensures the 2.4L engine is always running at its peak efficiency, preventing minor issues from turning into fuel economy drains.
