What is the gas mileage on a Lexus NX 300h?
The NX 300h typically delivers about 33 mpg combined, with around 31 mpg in city driving and 34–35 mpg on the highway, depending on year and drivetrain.
The Lexus NX 300h is a compact luxury hybrid SUV that combines a 2.5-liter Atkinson-cycle engine with electric motors. Because EPA fuel-economy numbers vary by year, trim, and whether the model is front-wheel drive (FWD) or all-wheel drive (AWD), it’s important to understand the typical ranges and the factors that influence real-world mileage. The following sections outline official estimates and practical considerations for maximizing efficiency.
EPA fuel economy by drivetrain
Below are representative EPA estimates for common NX 300h configurations seen in model years around the mid-2010s. Exact numbers can vary by year and test cycle.
- Front-wheel drive (FWD): approximately 31 mpg city, 35 mpg highway, for a combined around 33 mpg.
- All-wheel drive (AWD): approximately 31 mpg city, 34 mpg highway, for a combined around 32–33 mpg.
Note: Real-world mileage can differ from these figures based on driving conditions, maintenance, and climate. For the precise rating on your exact year and trim, check fueleconomy.gov or the EPA rating label on your vehicle.
Factors that affect mileage
Several variables influence observed fuel economy in everyday use. Understanding these can help you optimize efficiency with the NX 300h.
- Driving style: Smooth acceleration, steady speeds, and minimizing rapid braking improve hybrid efficiency.
- Climate control and electrical loads: A/C use, heating, and other accessories can reduce mpg, especially in extreme temperatures.
- Maintenance and tires: Proper tire inflation, regular servicing, and engine maintenance help maintain fuel economy closer to rated values.
In typical mixed driving, many NX 300h owners report mileage near the EPA estimates, with highway-focused trips often yielding favorable efficiency due to steady cruising and efficient power management.
Summary: The NX 300h generally achieves fuel economy in the low-to-mid 30s mpg range, with FWD models around 33 mpg combined and AWD versions slightly lower. For the exact numbers for your specific year and trim, consult the EPA ratings for your model year or fueleconomy.gov.
