What is the fuel consumption of the NX350?
The NX350’s fuel consumption in the United States is generally in the mid‑20s mpg, with about 23 mpg in city driving and 28 mpg on highways for front‑wheel-drive versions, and slightly lower figures for all‑wheel-drive models.
EPA ratings and what they mean for your drive
Below are the typical EPA estimates for recent NX350 models in the U.S. (gasoline, 2.4-liter turbo), broken out by drivetrain. Values can vary by model year and trim.
- NX350 FWD: about 23 mpg city, 28 mpg highway, 25 mpg combined (roughly 9.4 L/100 km combined).
- NX350 AWD: about 22 mpg city, 27 mpg highway, 24 mpg combined (roughly 9.8 L/100 km combined).
Note: Real-world fuel economy depends on many factors, including driving style, climate, and tire choice; winter fuel economy and frequent AC use can push city numbers lower than the EPA estimates.
What drives the differences in fuel use
Several factors determine how the NX350 performs in daily driving beyond the official numbers.
- Drivetrain weight and losses: AWD adds weight and power transfer losses compared with FWD, which modestly lowers efficiency.
- Model year and tuning: Updates to the engine, transmission, or tires can shift the ratings slightly between years.
- Environmental conditions: Cold weather, high-speed highway driving, or hilly terrain can reduce mpg.
- Accessories and load: Roof racks, heavy payload, and aggressive AC use can further reduce efficiency.
For shoppers and drivers, the EPA numbers provide a baseline, but expect real-world mpg to vary with conditions and personal driving habits.
Global context and how to read the numbers
In markets outside the United States, fuel-economy results are reported using different standards (such as WLTP), and conversions to liters per 100 kilometers can vary. If you are comparing across regions, check the local ratings for an apples-to-apples comparison.
Summary
The NX350 offers solid fuel efficiency for a compact luxury crossover, with EPA estimates typically placing combined mpg in the mid-20s for recent models. Front-wheel-drive variants tend to be a touch more efficient than all-wheel-drive versions. Consult the window sticker or EPA ratings for the exact year and configuration you are considering to get precise figures.

MPG Ratings
The Lexus NX 350 AWD and 350h F Sport Handling AWD share the same fuel efficiency ratings, which are 21/28/24 MPG city/hwy/combined⁴. However, the NX 350h has EPA-estimated ratings of 41/37/39 MPG city/hwy/combined⁴.
Does the Lexus Nx 350 require premium gas?
Yes, the Lexus NX 350 requires premium unleaded gasoline with an octane rating of 91 or higher to ensure optimal performance and engine health. Using a lower octane fuel can lead to engine knocking and may cause damage over time.
- Requirement: The NX 350 requires premium gasoline (91 octane or higher).
- Reason: The turbocharged engine is designed for premium fuel, and using it is crucial for performance and preventing long-term engine damage.
- Alternatives: The NX 250 requires regular unleaded gasoline, but the NX 350 and 350h require premium fuel.
- Potential issues: Using regular gas in a car that needs premium can lead to engine knocking and may even void the warranty.
