How big is the fuel tank on a Lexus RX hybrid?
Most Lexus RX hybrids use a 17.2-gallon tank (about 65 liters). This article explains how that figure applies across current RX hybrid models and how to verify the exact size for your car.
Current RX hybrid tank size
For the latest generation sold in North America, including the RX 350h and related hybrid variants, Lexus lists a fuel tank capacity of 17.2 gallons (65 liters). This size is standard across the contemporary RX hybrid lineup and supports the model’s efficiency-focused powertrain.
Variations by year, market, or drivetrain
While 17.2 gallons is the typical figure, there can be minor variations by model year, region, or drivetrain configuration (for example, front‑wheel drive vs all‑wheel drive). In some markets or older generations, the quoted tank capacity may differ by less than a gallon. For precision, always check the exact specification for your vehicle.
How to confirm the exact capacity for your vehicle
To verify your specific tank size, consult the owner's manual and the fuel-filler door label, which usually lists the tank capacity. You can also review Lexus’s official product pages for your model year or contact a Lexus dealer to pull the precise spec for your VIN.
Summary
The Lexus RX hybrid almost always uses a 17.2-gallon (65-liter) fuel tank, with small regional or model-year variations possible. For the exact figure on your car, check the owner’s manual, the fuel door label, or official Lexus specifications for your model year and trim.
