In contrast, the RX350, which replaced the RX330 starting in 2007, features a larger 3.5-liter V6 engine that produces 270 horsepower and 251 lb-ft of torque. This increased power output provides the RX350 with more responsive acceleration and improved passing capabilities compared to the RX330.


Fuel Economy


The larger engine in the RX350 also impacts its fuel efficiency. The RX330 was rated at 18 mpg city and 24 mpg highway, while the RX350 achieves 18 mpg city and 25 mpg highway. The slight improvement in highway fuel economy for the RX350 can be attributed to its more powerful yet efficient engine.
