25 MPG combined isn’t going to win any hypermiling contests, but it lands the 2024 Toyota Highlander 2.4L squarely in the heart of what its buyers expect: reliable family transport with reasonable operating costs. This isn’t a vehicle purchased for its groundbreaking efficiency; it’s bought for its reputation, practicality, and longevity. That 25 MPG is simply the price of entry for a competent and well-regarded three-row SUV.

City and highway performance

The EPA estimates for the 2024 Highlander 2.4L break down to 22 MPG in the city and 29 MPG on the highway. The slightly lower city figure reflects the engine’s need to work harder during stop-and-go traffic. The turbocharged 2.4L, while an improvement over the previous V6 in terms of torque, still needs to spool up in lower-speed conditions. Conversely, the highway figure of 29 MPG is achievable during steady-state cruising. This is due to the eight-speed automatic transmission’s ability to keep the engine in its most efficient range at higher speeds. These numbers reflect typical driving conditions, with a balanced mix of acceleration, braking, and constant speed.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 Toyota Highlander 2.4L is $1,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. This number is a useful benchmark for comparing running costs against other vehicles you may be considering. Keep in mind that your actual fuel costs may differ based on your driving habits, fuel prices in your area, and the type of fuel you use. If you do a lot of city driving, expect to spend closer to, or even above, this estimate. However, if your commute is primarily highway miles, you might beat the EPA’s projection.

Real-world expectations

While the EPA provides a standardized estimate, your real-world MPG may vary. Factors such as driving style, load, and terrain can significantly impact fuel consumption. Aggressive acceleration and heavy braking will naturally decrease fuel economy. Carrying a full load of passengers and cargo will also add strain on the engine. Steep hills and mountainous regions demand more power, which translates into increased fuel consumption. Regular maintenance, such as tire inflation and oil changes, can also influence the 2.4L engine’s efficiency. A well-maintained vehicle will generally perform closer to its EPA-estimated MPG than one that is neglected.

How it compares

The Highlander’s MPG stacks up reasonably well against its competition. The Kia Telluride, a popular choice in the three-row segment, hovers around 20 MPG combined, making the Highlander a more efficient choice. The Honda Pilot trails slightly behind the Toyota, at around 22 MPG combined, and the Nissan Pathfinder is similar. Even hybrid versions of competitive mid-size SUVs are challenged by the HIGHLANDER MPG across all years because the Highlander isn’t that far behind even hybrids. If outright fuel efficiency is the absolute top priority, a hybrid SUV is still the best play. However, for buyers who are wary of hybrid powertrains and prefer proven reliability, the Highlander 2.4L strikes a good balance, offering decent MPG without the complexity of a hybrid system. Don’t forget to compare all Toyota fuel economy data to see the full range.

Tips to maximize efficiency

One of the easiest ways to improve fuel economy with the 2.4L turbo is to monitor your tire pressure. Modern tire pressure monitoring systems (TPMS) make this simple. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended levels as indicated on the door jamb sticker.

Avoid aggressive driving habits. Rapid acceleration and hard braking consume excessive fuel. Instead, adopt a smoother, more progressive driving style. Anticipate traffic conditions and maintain a steady speed whenever possible. Use cruise control on the highway to help maintain a constant speed and optimize fuel consumption.

Keep your Highlander properly maintained. Regular oil changes, air filter replacements, and tune-ups ensure that the engine is running efficiently. A clean air filter allows optimal airflow to the engine, while fresh oil reduces friction and wear. Follow the manufacturer’s recommended maintenance schedule to keep your Highlander in top condition.

Minimize unnecessary weight. Remove any excess cargo from the vehicle. The heavier the vehicle, the more fuel it consumes. Carrying unnecessary items in the trunk or on the roof racks adds extra weight and increases aerodynamic drag, both of which negatively impact fuel economy. Only carry what you need.

Plan your trips and avoid peak traffic congestion. Stop-and-go traffic consumes significantly more fuel than highway driving. Try to time your trips to avoid rush hour, when possible. Using navigation apps to find the most efficient routes can also help you minimize fuel consumption. Idling also decreases fuel efficiency, so reduce idling time as much as possible.
