What is the fuel consumption of the NX300H?

The NX300h’s fuel consumption varies by market, year, and drivetrain, but typical figures place it around the low 30s in mpg on the U.S. cycle and about 5 L/100 km on European testing. This article breaks down the common ranges and what influences them.

The question centers on how efficiently the NX300h uses fuel in everyday driving. As a hybrid SUV, its economy depends on factors such as whether the model is front-wheel drive or all-wheel drive, the testing cycle used, and regional emission standards. Below are the main numbers you’ll see cited for this model, followed by a look at factors that can change real-world fuel use.

United States: EPA fuel economy estimates

In the U.S., official fuel economy numbers come from the EPA and reflect typical hybrid performance in everyday driving. For the NX300h, the drivetrain configuration has a noticeable impact on combined efficiency.

• Front-wheel-drive (FWD) NX300h: about 33 mpg combined (roughly 7.1 L/100 km).


• All-wheel-drive (AWD) NX300h: about 31–32 mpg combined (roughly 7.3–7.6 L/100 km).

These figures provide a practical benchmark for daily use, but real-world results can vary with speed, terrain, and load. The general takeaway is that the hybrid system delivers mid-30s mpg in optimal conditions for FWD and slightly lower figures for AWD configurations.

Europe and other markets: WLTP/NEDC figures

European testing uses WLTP (and historically NEDC) cycles, which typically yield slightly different numbers than EPA tests. For the NX300h, European combined fuel consumption generally falls in the low-to-mid 5 L/100 km range, depending on year and configuration.

• Typical European combined: approximately 4.8–5.5 L/100 km (varies by model year and drive layout).


• Note: Older cycles (NEDC) often reported lower numbers than WLTP; modern WLTP figures are the more accurate reference for current buyers.

These European figures aim to reflect real-world highway and city driving under WLTP conditions, though actual consumption depends on similar factors as in the U.S., such as driving style and climate control usage.

What factors influence NX300h fuel consumption?

Understanding which variables push consumption up or down helps explain why numbers can differ between test cycles and everyday driving.

• Drivetrain configuration (FWD vs. AWD): AWD typically uses more energy, lowering mpg slightly.


• Driving style: Gentle acceleration and steady speeds improve efficiency; aggressive driving reduces it.


• Terrain and traffic: Stop-and-go city driving lowers mpg relative to steady highway cruising.


• Climate control usage: A/C and heating impact fuel use, especially in extreme temperatures.


• Vehicle load and roof racks: Extra weight or aerodynamic drag reduces efficiency.


• Maintenance: Proper tire pressure, engine servicing, and hybrid battery health affect performance.

In practice, the NX300h can deliver better numbers in light-traffic highway cruising or when the hybrid system operates efficiently at steady speeds, while city driving, hills, and heavy loads tend to push consumption higher.

Summary

For the Lexus NX300h, typical guidance is: about 33 mpg combined for front-wheel-drive models in the United States, around 31–32 mpg combined for all-wheel-drive versions, and roughly 4.8–5.5 L/100 km in European WLTP testing. Real-world results will vary with drivetrain, driving style, conditions, and features in use. If you need the exact figure for a specific model year and market, consult the EPA ratings for the U.S. version or the WLTP/NEDC figures published for your region.

What is the real mpg of the Lexus NX300h?

Lexus NX300h ECONOMY AND EMISSIONS
Our actual real-life average after a week of driving the NX hybrid was 31.1mpg. The best we achieved with very gently driving was 39.4mpg.

Is the Lexus Nx 300 fuel efficient?

The 2021 Lexus NX 300 achieves an EPA-estimated 22 city/28 highway MPG.

How many miles per gallon does a 2015 Lexus NX300h get?

The 2015 Lexus NX 300h gets 35 mpg city / 31 mpg highway / 33 mpg combined for front-wheel-drive models and 33 mpg city / 30 mpg highway / 32 mpg combined for all-wheel-drive models. The combined fuel economy is 32-33 mpg, with the front-wheel-drive version having slightly better mileage.
 

• Front-Wheel Drive (FWD): 35 mpg city / 31 mpg highway / 33 mpg combined
