How many miles per gallon does a 2025 Lexus RX 350 hybrid get?
The 2025 Lexus RX 350h is EPA-rated to deliver about 38 miles per gallon combined with front-wheel drive and about 36 mpg with all-wheel drive. In more detail, EPA estimates are roughly 39 mpg city / 37 mpg highway / 38 mpg combined (FWD) and 37 mpg city / 35 mpg highway / 36 mpg combined (AWD).
These figures come from EPA testing and Lexus’ published data for the 2025 RX 350h, and they can vary with wheel size, trim level, climate-control usage, and driving conditions. The hybrid system in the RX 350h combines a 2.5-liter Atkinson-cycle engine with electric motors to optimize efficiency, particularly in urban driving where regenerative braking adds benefit. Below is a closer look at the official figures and the factors that influence real-world mileage.
Fuel economy by drivetrain
The following figures are EPA estimates for the RX 350h's two primary drivetrains. They reflect the most common configurations and wheel sizes, and may differ with other options.
- Front-Wheel Drive (FWD): 39 mpg city / 37 mpg highway / 38 mpg combined
- All-Wheel Drive (AWD): 37 mpg city / 35 mpg highway / 36 mpg combined
These EPA numbers provide a baseline for comparison across trims and driving conditions. Real-world results typically track within a few mpg of these estimates, depending on usage and environment.
What influences mpg in the RX 350h
Fuel economy in the RX 350h is shaped by a mix of powertrain design and how the vehicle is driven. The following factors commonly push real-world mpg up or down from EPA estimates.
- Driving conditions: City driving with frequent stops generally yields higher mpg for hybrids than sustained highway cruising, due to regenerative braking and efficient stop-start operation.
- Wheel size and tires: Larger wheels and lower-profile tires can reduce efficiency; factory-standard 18-inch wheels typically optimize mpg better than larger options.
- Climate control load: Using air conditioning or heating increases energy draw from the hybrid system, especially in extreme temperatures.
- Auxiliary loads: Roof racks, heavy payload, and aggressive acceleration can lower mpg.
- Battery state and hybrid tuning: The battery state of charge and how aggressively the system blends electric and gasoline power can affect your mileage on a given trip.
In practice, the RX 350h is tuned to emphasize efficiency, but individual results vary with how and where you drive.
Real-world mpg expectations and tips
For everyday driving, expect mpg to hover in the upper 30s to lower 40s mpg depending on conditions. To maximize efficiency, consider the following practical tips.
- Keep tires inflated to the recommended pressure to reduce rolling resistance.
- Plan routes that avoid heavy congestion when possible to minimize stop-and-go cycles.
- Use eco-driving techniques and moderate acceleration to optimize hybrid operation.
- Minimize HVAC use in mild weather and use seat heaters if available to reduce overall energy draw.
Despite best efforts, real-world mileage will vary with climate, terrain, and how heavily the vehicle is loaded.
Summary
The 2025 Lexus RX 350h offers strong hybrid efficiency for a midsize luxury SUV, with EPA estimates around 38 mpg combined for FWD and 36 mpg for AWD. City driving tends to yield favorable results for hybrids, while factors like wheel size, climate control, and payload can sway real-world numbers. If mpg is a priority, a careful choice of drivetrain and mindful driving habits can help maximize fuel economy.
