What kind of engine does the Lexus RX 350 have?
The Lexus RX 350 currently uses a 2.4-liter turbocharged inline-4 engine.
In its latest generation, the RX 350 pairs this turbocharged four with an 8-speed automatic transmission and offers all-wheel drive as an option, delivering about 275 horsepower and 317 lb-ft of torque. Earlier RX 350 models relied on a traditional 3.5-liter V6.
Engine options and history
Here is a concise look at the engine configurations that have powered the RX 350 across recent generations.
- 2015–2022 Lexus RX 350: 3.5-liter V6 engine (2GR-FKS), about 295 horsepower and 268 lb-ft of torque; 8-speed automatic; front-wheel drive standard, all-wheel drive available.
- 2023–present Lexus RX 350: 2.4-liter turbocharged inline-4 engine, about 275 horsepower and 317 lb-ft of torque; 8-speed automatic; all-wheel drive available.
- Note: The RX 350h (hybrid variant) uses a 2.5-liter Atkinson-cycle inline-4 hybrid system with electric motors, for a total of around 246 horsepower; it’s a separate drivetrain within the RX lineup.
The RX 350's engine evolution shows Lexus moving from a traditional V6 to a turbocharged four-cylinder in the current generation, while maintaining a hybrid option in the broader RX lineup.
What this means for buyers
Engine choice affects performance, efficiency, and driving feel. If you value strong low- to mid-range torque and smooth power delivery, the turbo-four in the latest RX 350 offers a modern balance of performance and efficiency. Those who prefer the character of a V6, especially in older models, might consider a late-model RX 350 with the 3.5L V6, while the RX 350h provides a more efficient hybrid option.
Summary: The RX 350’s current powertrain is a 2.4-liter turbocharged inline-4 producing roughly 275 horsepower and 317 lb-ft of torque, paired with an 8-speed automatic and optional AWD. Older RX 350s used a 3.5-liter V6, and the RX 350h is a hybrid variant with a different powertrain.
