How much gas does a Lexus NX hold?

The Lexus NX, a popular luxury crossover SUV, has a fuel tank capacity of 15.9 gallons or 60 liters. This allows the Lexus NX to have a respectable driving range on a single tank of gas, making it a practical choice for both city and highway driving.


Fuel Tank Capacity of the Lexus NX


The Lexus NX is available in several different models, including the NX 250, NX 350, and NX 350h hybrid. Regardless of the specific model, the fuel tank capacity remains the same at 15.9 gallons or 60 liters.


This fuel tank size is on the larger side for a compact luxury SUV, providing the Lexus NX with a good balance of range and efficiency. The larger tank size allows the NX to go further between fill-ups, which can be especially useful for longer road trips or commutes.


Driving Range and Fuel Economy


With a 15.9-gallon fuel tank and the Lexus NX's typical fuel economy ratings, the vehicle can achieve a driving range of around 400-450 miles on a single tank of gas.



  • The Lexus NX 250 has an EPA-estimated fuel economy of 25 mpg city, 33 mpg highway, and 28 mpg combined.

  • The Lexus NX 350 has an EPA-estimated fuel economy of 22 mpg city, 29 mpg highway, and 25 mpg combined.

  • The Lexus NX 350h hybrid model has an even higher EPA-estimated fuel economy of 41 mpg city, 37 mpg highway, and 39 mpg combined.


These fuel economy figures, combined with the 15.9-gallon tank, provide the Lexus NX with a respectable driving range that should meet the needs of most owners.


Refueling the Lexus NX


When it comes time to refuel the Lexus NX, the 15.9-gallon tank size means that a full tank will require a significant amount of gas, typically costing $50 or more depending on current fuel prices.
