Is RX 350 4 cylinder or 6 cylinder?
The current Lexus RX 350 uses a four-cylinder turbocharged engine. Historically, RX 350 models wore a six-cylinder powerplant, but the latest generation shifted to a four-cylinder turbo setup for better efficiency and practicality.
Current RX 350 engine details
In the latest generation, model years 2023 to present, the RX 350 is powered by a 2.4-liter turbocharged inline-4 engine delivering about 275 horsepower and 317 lb-ft of torque. It is paired with an 8-speed automatic transmission and is available with all-wheel drive. This marks a departure from the earlier V6 configuration that powered the RX 350 in previous generations.
Key specifications for the current RX 350 are:
- Engine: 2.4-liter turbocharged inline-4
- Horsepower: ~275 hp
- Torque: ~317 lb-ft
- Transmission: 8-speed automatic
- Drivetrain: Front-wheel drive or all-wheel drive (AWD) options
Overall, the RX 350 today uses a four-cylinder turbo engine rather than a traditional six-cylinder powerplant, reflecting Lexus’ shift to smaller, turbocharged mills in this segment.
Historical engine configurations
Earlier generations of the RX 350 were powered by a 3.5-liter V6 engine (Lexus 2GR-FE). That setup produced roughly 270–295 horsepower, depending on the model year, and was paired with rear- or all-wheel drive. The move to a turbocharged four-cylinder began with the 2023 redesign, aligning the RX 350 with newer compact-SUV powertrain trends.
Key engine configurations by era include:
- Pre-2023 RX 350: 3.5-liter V6 (2GR-FE) with approximately 270–295 hp, depending on year.
- 2023–present RX 350: 2.4-liter turbocharged inline-4 with about 275 hp and 317 lb-ft of torque; 8-speed automatic; AWD available.
In practice, the RX 350 badge today signifies a four-cylinder turbo engine in the latest generation, while older model years used a V6.
Summary
Bottom line: The RX 350 is four-cylinder in its current form, a shift from the V6 engines used in earlier generations. This change aims to balance performance with improved efficiency, though enthusiasts who prefer the traditional V6 may opt for older RX 350 models or other Lexus SUVs.
