2018 Toyota Highlander Hybrid AWD LE Plus: Fuel Economy Deep Dive

29 MPG combined is the key figure to understand when considering the 2018 Toyota Highlander Hybrid AWD LE Plus. It means you’re getting near-compact car fuel economy in a mid-size, three-row SUV with all-wheel drive, a trade-off many family buyers are willing to make to gain space, safety, and year-round usability. This isn’t a vehicle aimed at enthusiasts but rather families who need practicality without high fuel costs.

City and highway performance

The EPA breaks down the Highlander Hybrid’s fuel efficiency further, awarding it 30 MPG in the city and 28 MPG on the highway. The strong city rating is largely due to the hybrid system’s ability to recapture energy during braking and coasting, reducing the workload on the 3.5L V6 engine in urban driving situations. The slightly lower highway number reflects the increased reliance on the gasoline engine at higher speeds, though the electric motor system still assists to maintain decent fuel economy. The automatic (AV-S6) transmission is tuned to optimize efficiency, favoring lower engine speeds where possible while still providing adequate power when needed.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Toyota Highlander Hybrid AWD LE Plus at exactly $1,500. This estimate is based on driving 15,000 miles per year and using the then-national average fuel price during its testing cycle. Actual costs will vary based on individual driving habits, local fuel prices, and weather conditions, but this provides a baseline for comparing the Highlander Hybrid to other vehicles. For families logging significant miles, that $1,500 figure could represent significant savings compared to a non-hybrid SUV.

Real-world expectations

While the EPA figures provide a standardized benchmark, real-world fuel economy can vary. Drivers with a heavy foot or who frequently encounter stop-and-go traffic may see numbers closer to the lower end of the EPA range, perhaps dipping below 28 MPG combined. Conversely, those who prioritize smooth acceleration, anticipate traffic flow, and use the hybrid system’s capabilities to their fullest potential could potentially exceed the 29 MPG rating. Terrain also plays a role, hilly areas can negatively impact fuel economy, while flat terrain can help maintain or even improve it.

How it compares

The Highlander Hybrid’s fuel economy is a key selling point when stacked against its competitors. A non-hybrid, V6-powered Toyota Highlander achieves around 23 MPG combined, illustrating a significant advantage for the hybrid version. Direct competitors like the Ford Explorer, even with its EcoBoost engine, typically fall in the 20-24 MPG range. The Nissan Pathfinder offers similar fuel economy to the standard highlander. The Chrysler Pacifica Hybrid, a plug-in hybrid minivan, offers superior city fuel economy when operating on electric power, but its highway MPG is similar to the Highlander Hybrid once the battery is depleted. For those wanting to explore all Toyota options, see all Toyota fuel economy data. The Highlander Hybrid prioritizes seating, cargo volume, and all-weather capability combined with hybrid fuel economy over outright luxury or performance, and its fuel economy reflects that balance.

Tips to maximize efficiency

Gentle acceleration and braking are important to maximizing the Highlander Hybrid’s fuel efficiency. Avoid sudden bursts of speed or hard braking, as these actions force the gasoline engine to work harder and deplete the hybrid battery more quickly. Anticipate traffic flow and allow the vehicle to coast whenever possible, allowing the regenerative braking system to capture energy and recharge the battery.

Use the vehicle’s eco mode. This driving mode adjusts throttle response and climate control settings to prioritize fuel efficiency. While it might slightly reduce performance, it can contribute to noticeable fuel savings, especially during city driving. Don’t be afraid to experiment and see if the tradeoff aligns with your driving style.

Proper tire inflation is also vital. Underinflated tires increase rolling resistance, requiring the engine to work harder and reducing fuel economy. Regularly check your tire pressure and maintain it at the recommended levels, which are typically found on a sticker inside the driver’s side doorjamb.

Reduce unnecessary weight. Carrying excessive cargo in your Highlander Hybrid will reduce fuel economy. Remove any items that are not essential, such as sporting equipment or tools, to lighten the load and improve efficiency. These weight savings can add up over time.

Plan your trips efficiently. Combining errands into a single trip reduces cold starts, which are particularly detrimental to fuel economy. Also, consider driving during off-peak hours to avoid stop-and-go traffic, which can significantly reduce the hybrid system’s effectiveness. Comparing HIGHLANDER MPG across all years can help identify fuel-efficient models.
