What is the fuel economy of the RX350 l 100km?
The RX 350L typically consumes about 9.5 to 11.0 liters of fuel per 100 kilometers, depending on the year, drivetrain, and driving conditions. In familiar US terms, that translates to roughly 21–25 miles per gallon combined.
As a longer-wheelbase version of Lexus’s RX lineup, the RX 350L uses a 3.5-liter V6 paired with an 8-speed automatic transmission. Because it carries extra weight and, in many markets, comes with all-wheel drive, its efficiency sits in a modest range that varies by configuration and year. Real-world results will differ based on route, terrain, cargo, climate-control use, and how the vehicle is driven.
Known fuel-economy figures by drivetrain (L/100 km)
These are approximate EPA-style figures for recent RX 350L models, expressed in liters per 100 kilometers. Actual results may vary by year and market.
- Front-wheel drive (FWD): about 9.5–10.0 L/100 km (roughly 24–25 mpg combined).
- All-wheel drive (AWD): about 10.0–11.0 L/100 km (roughly 21–23 mpg combined).
Note that official numbers can vary slightly by model year and region, so consult the exact ratings for your vehicle’s year and market for precision.
What affects the RX 350L’s fuel economy
Fuel economy is shaped by a mix of design, configuration, and usage. Several factors tend to move the numbers up or down in daily driving.
- Vehicle load and aerodynamics: extra cargo, roof racks, or rigid additions increase drag and reduce efficiency.
- Driving conditions: city stop-and-go driving typically lowers MPG more than steady highway cruising.
- Tire type and inflation: proper tire pressure and rolling resistance influence economy; larger or performance tires can reduce efficiency slightly.
- Maintenance and conditions: regular maintenance, engine health, and proper oil type can affect fuel use.
Tips to maximize efficiency include keeping tires inflated to recommended pressures, removing unnecessary cargo and roof racks when not in use, smooth acceleration and deceleration, and using Eco or similar modes if the vehicle offers them.
Summary
The RX 350L generally falls in the 9.5–11.0 L/100 km range, depending on drivetrain and conditions, which corresponds to about 21–25 mpg combined. For the exact figure, check the EPA (or regional regulator) ratings for the specific model year and market, as there can be small year-to-year variations.
