What is the difference between RX350h and RX 500h?

The Lexus RX is a popular luxury SUV that comes in two hybrid variants: the RX350h and the RX500h. While both models offer enhanced fuel efficiency and performance compared to their non-hybrid counterparts, there are some key differences between the two.


Powertrain and Performance


The Lexus RX350h is powered by a 2.5-liter four-cylinder engine combined with two electric motors, producing a total system output of 240 horsepower. This setup provides a balance of efficiency and performance, with the RX350h achieving an EPA-estimated 36 mpg in combined city/highway driving.


In contrast, the Lexus RX500h features a more powerful 2.4-liter turbocharged four-cylinder engine paired with a high-output electric motor, delivering a combined output of 367 horsepower. This setup gives the RX500h a significant performance boost, allowing it to accelerate from 0 to 60 mph in just 5.9 seconds.p>

Driving Dynamics


The RX350h's powertrain is optimized for efficiency, providing a smooth and comfortable driving experience. It prioritizes fuel economy and emissions reduction over outright performance.


In contrast, the RX500h is tuned for a more engaging and dynamic driving experience. It features a sport-tuned suspension, upgraded brakes, and a more responsive throttle, making it the more performance-oriented option in the RX lineup.

Fuel Economy



  • The Lexus RX350h achieves an EPA-estimated 36 mpg in combined city/highway driving, making it the more fuel-efficient option.

  • The Lexus RX500h, with its more powerful powertrain, achieves an EPA-estimated 29 mpg in combined city/highway driving.


In summary, the Lexus RX350h is the more efficient and balanced hybrid option, while the RX500h prioritizes performance and a more engaging driving experience. Buyers should consider their priorities in terms of fuel economy, power, and driving dynamics when choosing between these two Lexus hybrid SUVs.
