Is RX350 4-cylinder or 6 cylinder?
The RX 350's engine configuration depends on the model year: the latest RX 350 uses a 2.4-liter turbocharged four-cylinder, while earlier RX 350 models used a 3.5-liter V6 (six cylinders).
Understanding this requires looking at Lexus' generation timeline. The RX lineup was redesigned for 2023, shifting the base RX 350 to a turbocharged four-cylinder. Hybrid variants within the RX family use different powertrains, and older non-hybrid RX 350s relied on the V6.
Engine configurations by generation
The following summarizes the engine setups for the RX 350 across generations.
- 2016-2022: Third-generation RX 350 powered by a 3.5-liter V6 engine, producing around 295 horsepower and 268 lb-ft of torque.
- 2023-present: Fourth-generation RX 350 uses a 2.4-liter turbocharged inline-4 engine, about 275 horsepower and 317 lb-ft of torque (AWD available).
This reflects the core change: a shift from a naturally aspirated V6 to a compact turbocharged four-cylinder in the base RX 350, with hybrid variants offering different powertrains.
Performance and efficiency considerations
Here is a quick comparison of the practical implications for consumers considering these powertrains.
- V6 (3.5L) in older RX 350: smoother power delivery and strong midrange torque, but lower fuel economy compared with modern turbo-four-era models.
- Turbo 4 (2.4L) in latest RX 350: competitive horsepower with improved highway/overall efficiency and newer emissions tech.
In practice, buyers today who want an RX 350 will be getting the four-cylinder turbo in the base model. If you are shopping older used models, you may encounter the V6 version. For hybrid options and higher-performance variants, consider RX 350h or RX 500h, which use different powertrains.
Summary
The RX 350 has evolved from a 3.5-liter V6 to a 2.4-liter turbocharged four-cylinder in its current generation. Engine choice depends on model year and trim, with hybrids offering additional powertrain options.
Which Lexus SUV has a 6 cylinder?
