How big is the gas tank on a 2024 Lexus RX?
The gas tank on the 2024 Lexus RX is 17.2 gallons (65 liters), a size that applies to most trims in the lineup.
The question about tank size matters because it influences how far you can drive between fill-ups, especially when comparing gasoline-only models to hybrids. Below is a breakdown of the official tank capacity and what it means for daily use.
Tank capacity across the RX lineup
Before listing the specifics, note that Lexus publishes a standard fuel-tank size of 17.2 gallons for the RX family. The following items reflect the commonly cited figures for current trims.
- RX 350 (gasoline): 17.2 gallons (65 liters)
- RX 350h (hybrid): 17.2 gallons (65 liters)
- RX 500h (hybrid): 17.2 gallons (65 liters)
Across these formats, the tank capacity remains effectively the same, providing a consistent basis for planning trips and fueling stops.
Real-world implications
Fuel-tank size interacts with the powertrain to determine driving range and refueling frequency. Gasoline RX models typically offer solid range numbers for daily commuting and longer trips, while hybrid variants tend to achieve higher overall fuel economy, extending the distance per tank.
Impact on driving range
Because tank size is fixed at 17.2 gallons, your actual range depends on EPA-estimated fuel economy for the specific powertrain and your driving habits. In practice, hybrids generally deliver more miles per tank than the gasoline-only version, especially on mixed or highway driving.
Additional considerations
Other factors that can influence how often you fill up include driving style, climate control use, tire size, and terrain. If you regularly drive long highway trips, the 17.2-gallon tank will provide a useful cushion for planning overnight fueling stops.
Summary
The 2024 Lexus RX typically comes with a 17.2-gallon (65-liter) fuel tank across its gasoline and hybrid variants, including the RX 350, RX 350h, and RX 500h. This large enough tank supports practical, multi-day driving ranges, with hybrids usually delivering higher miles per tank due to better fuel efficiency. For most owners, the tank size translates to planning for refuels every several hundred miles, depending on driving conditions and powertrain choice.
