How big is the gas tank on a Lexus RX 500h F Sport?
The gas tank on the Lexus RX 500h F Sport is 17.2 gallons (about 65 liters). This tank size is standard for the current RX hybrid lineup and is not altered by the F Sport trim.
Tank size in context
The RX 500h F Sport sits within Lexus’s fourth‑generation RX family, where hybrid models typically share the same fuel‑tank capacity. The 17.2‑gallon tank supports the vehicle’s hybrid powertrain and aims to balance driving range with overall weight and efficiency. The F Sport designation affects suspension, styling, and interior appointments, not tank capacity.
Markets and potential variations
In most regions where the RX 500h is sold, official specifications list a 17.2‑gallon (65‑liter) tank. Some regional listings may show minor rounding differences or note slightly different figures due to equipment added as standard, but any variance is usually small and does not reflect a meaningful change in range.
Estimated range and practical considerations
With a 17.2‑gallon tank and the RX 500h’s hybrid efficiency, drivers can expect a practical range that covers several hundred miles on a full tank, depending on driving conditions, speed, and how often the hybrid system engages electric assist. Real‑world mileage will vary, but the tank size is designed to minimize frequent refueling on long trips.
Summary
Bottom line: The Lexus RX 500h F Sport uses a 17.2‑gallon (65‑liter) gas tank, the same size as other RX hybrids in the current generation. The F Sport trim does not change tank capacity, and driving range will depend on how the vehicle is driven and the conditions encountered.
