How many gallons does a Lexus hybrid hold?

Lexus hybrids generally hold between about 11 and 22 gallons of fuel, with most models in the mid-teens. The exact capacity varies by model and year.


The question varies because Lexus offers multiple hybrid lines—from subcompact crossovers to full-size luxury SUVs. Tank size is closely tied to vehicle size, design, and intended range, so differences are expected across the lineup.

  • Subcompact hybrids (for example, UX 250h): about 11–12 gallons

These figures give a practical sense of fueling needs. The actual capacity may be slightly outside these ranges depending on model year and regional specs.


How to verify your exact tank capacity


To find the precise figure for your Lexus hybrid, use the official sources: check the window sticker when the vehicle is on the lot, view the digital or printed owner’s manual, or consult Lexus’ official model pages or dealer parts and specs. The VIN can also be used to pull up exact specifications for your car.


Summary


Fuel tank capacities among Lexus hybrids vary by model, but you can expect a general range from about 11 to 22 gallons. For any purchase or ownership decision, verify the exact value for your specific model and year, since it directly affects driving range and refueling frequency.
