The 2018 Toyota Highlander with the 2.7L four-cylinder engine gets 22 MPG combined, and that number needs context. It’s not a hybrid. This Highlander configuration offers Toyota’s reliable reputation and three-row practicality for the lowest price. Buyers who prioritize initial cost and a proven track record over top fuel efficiency may find this model appealing.
City and highway performance
The 22 MPG combined rating breaks down to 20 MPG in the city and 24 MPG on the highway. The engine’s limitations likely cause these figures when hauling around a vehicle of this size. In city driving, the heavier Highlander requires more effort to accelerate frequently, reducing the MPG. On the highway, the engine can settle into a more efficient cruising speed, even though the aerodynamics aren’t great.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2018 Toyota Highlander 2.7L at $2,000. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will change based on your driving habits, the type of driving you do (more city versus highway), and fuel prices in your area. This $2,000 figure is a standard benchmark for comparison against other vehicles, but it’s an estimate.
Real-world expectations
The EPA figures provide a baseline, but real-world fuel economy can vary. Owners report achieving the advertised 24 MPG on the highway when driving carefully. Aggressive driving, frequent short trips, or consistently carrying a full load of passengers and cargo will likely lower those numbers. The Highlander’s size and weight are constant factors, so driving style is important in maximizing fuel efficiency. Tire pressure, maintenance, and weather conditions can also affect MPG.

How it compares
The 2018 Highlander 2.7L’s fuel economy isn’t as good as V6 or Hybrid versions compared to other three-row SUVs. The Honda Pilot, with its more efficient V6, often gets around 23 or 24 MPG combined. The Ford Explorer, especially with the turbocharged EcoBoost engines, can dip below 20 MPG combined. A Chrysler Pacifica minivan gets a 22 MPG combined rating with its V6, but the Pacifica Hybrid offers significantly better efficiency. In the Toyota family, the Highlander Hybrid gets an EPA estimated combined MPG of 30. Buyers choose the 2.7L Highlander because of its lower initial cost and expected reliability, accepting the lower fuel economy as a trade-off.

Tips to maximize efficiency
Avoid aggressive acceleration and hard braking. The 2.7L engine in the Highlander needs to work harder to move the vehicle quickly, so a gentle foot on the accelerator saves fuel. Watch traffic flow and maintain a steady speed.
Ensure your tires are inflated. Underinflated tires create more rolling resistance, which reduces fuel efficiency. Check your tire pressure and inflate them to the pressure recommended on the doorjamb sticker. This is important if you often carry heavy loads.
Reduce weight. Extra cargo adds strain to the engine and lowers fuel economy. Remove any items you don’t need from the vehicle, especially heavy objects in the cargo area. Weight reductions add up.
Consider removing the roof rack unless you need it. Roof racks increase aerodynamic drag, especially at highway speeds. Removing it improves fuel efficiency, even slightly.
Follow the maintenance schedule. Regular oil changes, air filter replacements, and spark plug maintenance help your engine run well. A well-maintained engine delivers better fuel economy.
