How big is the gas tank on a RC 350?
The RC 350’s fuel tank capacity is 17.4 gallons (66 liters) in most recent US-spec models. This figure is standard for current production, with only minor variations possible by year or market.
The Lexus RC 350 blends sporty performance with everyday practicality, and the gas tank size directly affects how far you can drive between refuels. This article breaks down the official capacity, how it translates into real-world range, and any year-to-year or market variations you should know about.
Tank size at a glance
Before diving into details, note that the official capacity is a fixed specification for most RC 350 configurations, with small tolerances in manufacturing. The following summary reflects typical factory figures for recent models.
- Most current RC 350 models: 17.4 gallons (66 liters).
- Usable capacity is slightly less than the full tank due to reserve fuel and tank geometry.
- Trims and markets generally share this capacity, though rare regional variations can occur.
With a 17.4-gallon tank and typical driving, you can expect a practical range that depends on fuel economy, driving style, and conditions. Real-world figures vary, but the nominal capacity remains 17.4 gallons for the vast majority of US-spec RC 350 cars.
Driving range considerations
To translate tank size into range, multiply the tank capacity by the vehicle’s fuel economy. For a ballpark estimate, if the RC 350 averages in the low-to-mid 20s miles per gallon (combined), a full 17.4-gallon tank would yield roughly 350–450 miles on a full tank, depending on drivetrain (RWD vs. AWD), tire size, and driving conditions.
- RWD versions generally offer better highway efficiency, increasing potential range on long trips.
- AWD variants may have slightly reduced fuel economy due to the added drivetrain losses.
- Actual range varies with year, market, and specific EPA ratings for your configuration.
In everyday use, most drivers refuel before the gauge reaches empty, so the practical range is typically sufficient for daily commutes and longer trips with planned stops along the way.
Tank size by year and market
Although the US-spec RC 350 commonly uses a 17.4-gallon tank, there can be minor differences by year or market due to emissions equipment, optional AWD, or local labeling. The standard figure remains 17.4 gallons for the vast majority of recent RC 350 vehicles.
- US-spec RC 350 (latest years): 17.4 gallons.
- Some international markets may list 66–67 liters (roughly 17.4–17.7 gallons) depending on local specs, but the practical capacity is typically 17.4 gallons.
Always check the door jamb sticker or your owner's manual for the exact figure for your year and VIN, as there can be small, model-specific variations.
Summary
In practice, the Lexus RC 350 uses a 17.4-gallon (66-liter) gas tank, offering a practical driving range that generally falls in the roughly 350–450 mile band depending on driving conditions and fuel economy. For precise numbers, consult your vehicle’s manual or the official Lexus specifications for your exact year and trim.
How many miles can a Lexus RX 350 get on a full tank of gas?
A Lexus RX 350 can travel approximately 400 to 450 miles on a full tank, depending on the model year, whether it's front-wheel drive (FWD) or all-wheel drive (AWD), and your driving conditions. For the most recent models with EPA ratings of about 22-29 mpg combined and a 17.9-gallon tank, you can expect around 390 to 510 miles.
Factors affecting your range
- Model Year: Newer models often have different MPG ratings. For example, a 2024 RX 350 has a combined MPG of approximately 23-24 mpg, while a 2022 model has a combined MPG of around 22.8 mpg.
- Drivetrain: FWD models generally have better fuel economy than AWD models. For instance, a 2024 RX 350 FWD model gets 22 mpg city / 29 mpg highway, while an AWD model gets 21 mpg city / 28 mpg highway.
- Driving Conditions: City driving with stop-and-go traffic will use more gas than steady highway driving.
- Driving Habits: Aggressive driving, such as rapid acceleration and hard braking, will reduce your fuel efficiency and range.
- Fuel Tank Capacity: While most Lexus RX 350 models have a 17.9-gallon fuel tank, hybrid versions may have different tank capacities.
