How many liters is a Lexus RX 350?
The Lexus RX 350’s liters refer to two measurements: its engine displacement of 3.5 liters and its fuel-tank capacity of about 65 liters. These figures can vary slightly by model year and market.
In this article, we break down what those liters mean in practical terms and provide the latest specifications for recent RX 350 models.
Engine displacement (liters)
The RX 350 uses a 3.5-liter V6 engine in most current models, delivering a balance of power and efficiency that Lexus has carried through multiple generations. This displacement is a measure of the engine’s size and capacity, not a fuel quantity.
Before listing the core figures, note that engine size is a fixed specification that typically remains constant within a given generation, while horsepower and torque can vary by year and tuning.
- Engine displacement: 3.5 liters (V6, 2GR-FKS configuration in recent models).
- Common horsepower: around 295 hp (varies by year/market).
- Turbocharging: none on the RX 350; power is achieved through naturally aspirated V6 design and advanced fuel delivery.
In short, the RX 350’s engine is a 3.5-liter V6, a primary specification that remains a hallmark across recent model years.
Fuel tank capacity (liters)
Fuel tank capacity refers to the volume of fuel the tank can hold. For the RX 350, the standard tank is typically about 65 liters, which translates to roughly 17.2 US gallons. Actual capacity can vary slightly by market or trim level, but 65 L is the widely cited figure for most current models.
Before the list, this paragraph sets expectations about what the liters describe in practical terms for refueling and range.
- Fuel tank capacity: 65 liters (approximately 17.2 US gallons).
So, when asked how many liters the RX 350 is, the most common reference is 65 liters for fuel capacity, with 3.5 liters describing engine size.
Summary
For a Lexus RX 350, liters can refer to two key specifications: engine displacement (3.5 L) and fuel-tank capacity (about 65 L). These figures are standard for current-generation models, though minor market and year-to-year variations can occur. Always check the exact specification for your vehicle’s VIN and model year in the owner’s manual or official Lexus site.
