What engine does the Lexus RX 350 use?
The current Lexus RX 350 uses a 2.4-liter turbocharged inline-four engine, delivering about 275 horsepower and 317 lb-ft of torque, paired with an eight-speed automatic transmission. Older RX 350 models relied on a 3.5-liter V6.
Across its history, the RX 350 has featured different powertrains depending on model year and market. This article explains the present engine setup and how the lineup has evolved over time.
Current engine configuration in the latest RX 350
Key specifications for the current RX 350 engine configuration are summarized below.
- Engine: 2.4-liter turbocharged inline-four (I4)
- Horsepower: 275 hp (206 kW) at roughly 5,500–6,000 rpm
- Torque: 317 lb-ft (430 Nm) at roughly 1,700–2,400 rpm
- Transmission: 8-speed automatic
- Drivetrain: AWD is commonly available; FWD is offered on some trims
The move to a turbocharged four-cylinder marks a shift from the prior V6 setup, reflecting a broader industry trend toward downsized engines with improved efficiency.
Engine history in the RX 350 lineage
Before the current generation, the RX 350 relied on a naturally aspirated V6 for many years, with variations depending on year and market.
- Earlier RX 350 generations (roughly 2010–2022 in the U.S.) used a 3.5-liter V6 engine (2GR-FKS / 2GR-FSE), producing about 295 hp and 268 lb-ft of torque
- The V6 was typically paired with a 6- or 8-speed automatic transmission, and AWD was commonly available
In summary, the RX 350’s powertrain has evolved from a traditional V6 to a modern turbocharged four-cylinder in the latest models, with the hybrid variant offering a different powertrain altogether.
Variant note: RX 350h and other powertrains
The RX 350h, when chosen, uses a hybrid setup that combines a 2.5-liter inline-four gasoline engine with electric motors, delivering a combined output around 246 hp and emphasizing efficiency over peak horsepower.
Summary: The current RX 350 uses a 2.4-liter turbocharged inline-four; older RX 350s used a 3.5-liter V6; the hybrid variant uses a separate powertrain configuration.
Summary
The Lexus RX 350’s engine lineup has shifted from a robust V6 to a smaller turbocharged four-cylinder in the latest models, with the RX 350h offering a distinct hybrid powertrain. For precise specifications, always verify the model year and market, as figures can vary.
