What is the fuel consumption of the 2024 NX 350h?
The 2024 NX 350h achieves roughly 38 mpg in combined driving, with official EPA estimates around 39 mpg city and 37 mpg highway for front-wheel drive, and about 37 mpg city and 35 mpg highway for all-wheel drive.
Powered by a 2.5-liter Atkinson-cycle inline-four paired with two electric motors, the NX 350h delivers about 239 horsepower in a self-charging hybrid setup. Efficiency varies by drivetrain, terrain, and driving style, and real-world mpg may differ from EPA estimates.
EPA fuel economy ratings vary by drivetrain and testing methodology. The following figures reflect the latest official estimates for the NX 350h in common configurations.
- Front-Wheel Drive (FWD): 39 mpg city / 37 mpg highway / 38 mpg combined
- All-Wheel Drive (AWD): 37 mpg city / 35 mpg highway / 37 mpg combined
These numbers provide a baseline for planning fuel costs; actual mileage depends on usage, climate control, terrain, and driving habits.
Hybrid powertrain and efficiency details
The NX 350h uses Lexus's self-charging hybrid system: a 2.5-liter four-cylinder Atkinson-cycle engine paired with dual electric motors and a continuously variable transmission (ECVT). The system delivers approximately 239 horsepower, prioritizing smooth, efficient acceleration and steady highway cruising.
Hybrid powertrain overview
In city driving, the electric motor assist and regenerative braking help keep the gasoline engine off at low speeds, boosting efficiency. On the highway, the gasoline engine provides consistent power with the hybrid system optimizing gear ratio and battery usage for economical cruising.
Real-world efficiency depends on factors like speed, load, climate-control usage, and terrain. The vehicle’s Eco and EV modes can help optimize hybrid operation, but actual performance will vary by conditions.
Tips to maximize fuel economy
To get the most from the NX 350h’s hybrid system, consider these practical tips:
- Keep tires properly inflated and follow regular maintenance to maintain drivetrain efficiency.
- Use Eco mode for city driving to emphasize battery assist and smoother throttle response.
- Avoid aggressive acceleration and excessive speeds; steady, moderate speeds improve mpg.
- Plan trips to minimize cold-start inefficiencies; a warm engine and battery are more efficient.
Note that the combined mpg shown by EPA assumes normal driving conditions and standard test cycles; your results may vary based on how you drive and where you drive.
Summary: The 2024 NX 350h offers competitive hybrid efficiency for a compact luxury SUV, with EPA estimates around 38 mpg combined (39/37 city/highway for FWD and 37/35 for AWD). Real-world mileage will depend on driving style and conditions, but the system is designed to maximize efficiency without sacrificing performance.
