What is the difference between RX450h and RX500h?

The Lexus RX450h and RX500h are both hybrid luxury SUVs, but they have some key differences in terms of their powertrain, performance, and fuel efficiency. The RX450h is a traditional hybrid that combines a gasoline engine with an electric motor, while the RX500h is a more advanced plug-in hybrid with a larger battery pack and more electric-only driving range.


Powertrain and Performance


The Lexus RX450h uses a 3.5-liter V6 gasoline engine paired with two electric motors, producing a combined system output of 308 horsepower. The RX500h, on the other hand, features a 2.5-liter four-cylinder engine combined with a more powerful electric motor and a larger 18.1 kWh battery pack, resulting in a total system output of 367 horsepower.p>

This increased power output in the RX500h translates to faster acceleration, with the vehicle able to go from 0 to 60 mph in around 5.7 seconds, compared to the RX450h's 7.9-second 0-60 mph time. The RX500h also has a higher top speed of 124 mph, while the RX450h is limited to 112 mph.


Fuel Efficiency and Electric Range


The Lexus RX450h is rated for 31 mpg in the city and 28 mpg on the highway, for a combined fuel economy of 30 mpg. The RX500h, with its larger battery pack, can travel up to 36 miles on electric power alone before the gasoline engine kicks in, and it has a combined fuel economy rating of 27 mpg.p>

While the RX500h's electric-only range and overall fuel efficiency are slightly lower than the RX450h, the increased performance and power of the RX500h may be worth the trade-off for some buyers.
