The Lexus RX is a popular luxury SUV that comes in several variants, including the RX350H and RX500H. While both models share the RX nameplate, they have distinct differences in terms of their powertrain, performance, and fuel efficiency.


Powertrain and Performance


The RX350H is a hybrid model that combines a 2.5-liter four-cylinder gasoline engine with an electric motor, producing a combined output of 308 horsepower. This hybrid system allows the RX350H to achieve impressive fuel efficiency, with an EPA-estimated 36 miles per gallon in the city and 33 miles per gallon on the highway.


In contrast, the RX500H is a more powerful, non-hybrid model that features a 2.4-liter turbocharged four-cylinder engine, paired with a high-output electric motor. This combination delivers a total output of 367 horsepower, making the RX500H the more performance-oriented variant of the two. However, the RX500H's fuel efficiency is lower than the RX350H, with an EPA-estimated 26 miles per gallon in the city and 29 miles per gallon on the highway.
