Is the Lexus Nx 350 good on gas?

The Lexus NX 350 is reasonably efficient for a compact luxury SUV powered by a turbocharged gasoline engine. In typical configurations, its EPA fuel economy sits in the mid-20s to low-30s mpg, with front-wheel-drive versions generally closer to the higher end and all-wheel-drive versions a notch lower. For the best efficiency, consider Lexus’s hybrid variants, the NX 350h or the plug-in NX 450h+.


What affects its fuel economy


Several factors determine real-world mileage, including drivetrain, driving style, and tire choice.



  • Drivetrain configuration (FWD vs AWD): All-wheel drive adds weight and drivetrain losses, typically lowering mpg slightly compared with front-wheel drive.

  • Driving style: Aggressive acceleration, high speeds, and frequent braking reduce efficiency.

  • Tire type and pressure: Properly inflated, low-rolling-resistance tires help; underinflated tires hurt economy.

  • Vehicle load and accessories: Passengers/cargo, roof racks, and other accessories increase drag and weight.

  • Model year and trim: EPA ratings can shift with tuning, emissions equipment, and gearing changes.


Considering these factors, real-world mileage will vary, but the NX 350 remains relatively efficient for its category when driven calmly.


EPA estimates and real-world performance


The following figures refer to common configurations used by automakers and reflect typical ranges for recent NX 350 models. Actual numbers depend on model year and market.



  1. NX 350 FWD: about 26 mpg city, 31 mpg highway, 28 mpg combined.

  2. NX 350 AWD: about 25 mpg city, 28 mpg highway, 26 mpg combined.


In real-world driving, most owners report fuel economy in the mid-20s to upper-20s mpg with mixed city/highway use. Heavier traffic, cold weather, and frequent starts can push numbers lower, while steady highway cruising can push them toward the upper end of the range.


NX 350 vs. hybrid variants for fuel economy


Hybrid alternatives offer higher efficiency in daily driving


To maximize miles per gallon, Lexus provides hybrid versions: the NX 350h (regular hybrid) and the plug-in NX 450h+. These powertrains shift the efficiency target, with the hybrid delivering better city mileage and, in the plug-in variant, the ability to run on electric power for short trips.



  • NX 350h: Generally more efficient than the gas-only NX 350, especially in city driving, due to the electric assist.

  • NX 450h+: Offers a longer electric-only range, greatly reducing gasoline use for short commutes when charged regularly.


For buyers focused on fuel economy, the hybrid options represent meaningful gains over the gas NX 350, though the trade-off can be higher upfront cost and different maintenance considerations.


Tips to maximize fuel economy


Even within the NX 350 lineup, several practical steps can help squeeze more miles per gallon from every trip:



  1. Maintain proper tire pressure and rotate tires as recommended by Lexus.

  2. Use Eco or similar fuel-efficiency modes if equipped, and optimize cruise control on highways.

  3. Avoid aggressive acceleration and rapid braking; smooth driving improves efficiency.

  4. Keep weight to a minimum and remove roof racks when not in use.

  5. Schedule regular maintenance: clean air filter, spark plugs, and oil changes can affect efficiency.


These practices can make a noticeable difference over time, helping the NX 350 deliver closer to its EPA estimates in daily use.


Summary


The Lexus NX 350 is reasonably efficient for a compact luxury SUV with a turbocharged gasoline engine. Its mpg varies by drivetrain and model year, with front-wheel-drive configurations typically pulling ahead of all-wheel-drive versions. For buyers who prioritize fuel economy, the hybrid NX 350h and the plug-in NX 450h+ offer clearer advantages, especially in city driving or for short commutes. Consider driving style, load, and access to charging when evaluating total fuel costs.
