What is the fuel economy of a 2018 Lexus RX 350 L 100km?
In 100-kilometer terms, the 2018 Lexus RX 350L typically consumes about 10.2 liters of fuel per 100 km with front-wheel drive and about 10.7 L/100 km with all-wheel drive, based on EPA estimates of 23 mpg combined (FWD) and 22 mpg combined (AWD).
These figures come from the U.S. Environmental Protection Agency and reflect mixed driving, including city and highway conditions. Real-world economy can vary with driving style, terrain, payload, and tire choice.
EPA fuel-economy numbers for the 2018 RX 350L
The EPA provides separate fuel-economy figures for front-wheel drive (FWD) and all-wheel drive (AWD) versions of the 2018 RX 350L. The model uses a 3.5-liter V6 engine paired with an eight-speed automatic transmission.
- Front-Wheel Drive (FWD): 20 mpg city / 27 mpg highway / 23 mpg combined
- All-Wheel Drive (AWD): 19 mpg city / 26 mpg highway / 22 mpg combined
Combined mpg values are typically used for quick comparisons, but actual mileage depends on conditions and driving style.
Converting mpg to liters per 100 kilometers
To compare with metric consumption figures, you can convert miles-per-gallon to liters-per-100-kilometers. The following approximations come from the EPA combined ratings above.
- 23 mpg combined (FWD) ≈ 10.2 L/100 km
- 22 mpg combined (AWD) ≈ 10.7 L/100 km
In practice, drivers can expect roughly 10.2–10.7 L/100 km in typical mixed driving for the 2018 RX 350L, depending on drivetrain.
Real-world factors that influence economy
- Driving style (rapid acceleration, heavy braking) tends to raise consumption.
- Terrain and terrain-based factors (hills, mountains) can increase fuel use.
- Payload and passenger load add weight, reducing efficiency.
- Tire type and tire pressure impact rolling resistance and economy.
- Maintenance and fuel quality can also affect mpg.
Understanding these factors helps explain why real-world numbers may differ from EPA estimates.
What this means for buyers
For shoppers considering a 2018 RX 350L, the key takeaway is that the vehicle offers two EPA-rated efficiency paths: about 23 mpg combined with FWD and about 22 mpg combined with AWD, translating to roughly 10.2 and 10.7 L/100 km, respectively. If fuel economy is a priority, a FWD model will typically deliver the better combined figure, while AWD provides the added traction for varied conditions at a modest cost to efficiency.
Summary
The 2018 Lexus RX 350L achieves approximately 23 mpg combined (10.2 L/100 km) with front-wheel drive and about 22 mpg combined (10.7 L/100 km) with all-wheel drive. Real-world results vary with driving style and conditions, but these figures give a solid baseline for planning fuel costs on a 100-km trip.
