What is the average mileage for a Lexus NX 300?
There isn’t a single number for the NX 300, because the name has referred to different generations. In the current lineup, a gas NX 350 averages about 28 mpg combined, while the NX 350h hybrid averages about 38 mpg combined.
Understanding the NX 300 designation
The NX 300 label has been used on various generations and markets. Early first-generation NX models used a 2.0-liter turbo engine and carried the NX 300 name. In recent years, Lexus shifted to a two-model approach for the NX family: the NX 350 (gas) and the NX 350h (hybrid). Because of these changes, “average mileage” depends on which generation and drivetrain you’re talking about, as well as whether the vehicle is front-wheel drive or all-wheel drive.
Current Lexus NX lineup: fuel-economy numbers
Below are typical EPA fuel-economy figures for the latest NX versions, with a note that real-world mpg varies by driving style and options.
- NX 350 (gas, 2.4L turbo) — about 28 mpg combined (roughly 25 mpg city / 32 mpg highway).
- NX 350h (hybrid) — about 38 mpg combined (roughly 39 mpg city / 37 mpg highway).
These figures are the EPA estimates for recent model years. Real-world mileage can be lower or higher depending on conditions, maintenance, and driving habits.
Older NX 300 generations: mpg in review
The NX 300 name was used on earlier generations in some markets, and those versions typically posted lower-to-mid-20s mpg combined on gas models, with hybrid variants delivering better efficiency into the low- to mid-30s mpg combined.
- Early NX 300 (gas) — roughly 25–30 mpg combined, depending on drivetrain and year.
- NX 300h (hybrid) — roughly 30–35 mpg combined, varying with year and configuration.
Again, mpg varies by year, engine, and drivetrain; if you have a specific model year in mind, you can pull the official EPA ratings for precise figures.
Summary
To gauge the “average mileage” for a Lexus NX 300, you must specify the year and drivetrain. For the current-generation lineup, expect about 28 mpg combined for the NX 350 (gas) and about 38 mpg combined for the NX 350h (hybrid). Historically, the NX 300 name covered older models whose mpg typically ranged from the mid-20s (gas) to the low-to-mid-30s (hybrid). Always check the EPA rating for the exact vehicle and consider real-world factors that can affect mileage.
