The 2020 Lexus RX 350 has an EPA-estimated fuel economy of 20 miles per gallon (mpg) in the city, 27 mpg on the highway, and 23 mpg combined. This midsize luxury SUV offers a comfortable and refined driving experience, but its gas mileage is on the lower end compared to some of its competitors in the segment.


Detailed Fuel Economy Breakdown


The 2020 Lexus RX 350 is powered by a 3.5-liter V6 engine that produces 295 horsepower. It is available with either front-wheel drive or all-wheel drive configurations.
