The Lexus RX 350 AWD ECT-i, launched in December 2022, represents the fifth generation of Lexus’s popular luxury crossover SUV. Positioned as a core model within the RX lineup, it serves as a bridge between the more fuel-efficient hybrid variants and the forthcoming high-performance RX 450h+ plug-in hybrid. This variant is characterized by its 2.4-liter turbocharged inline-four engine paired with an 8-speed automatic transmission and standard all-wheel drive, aiming to deliver a balance of power, refinement, and capability for the North American market. The RX V designation signifies this generation, building upon the legacy of the RX series as a pioneer in the luxury crossover segment.

Powertrain & Engine Architecture
The RX 350 utilizes the T24A-FTS, a 2.4-liter inline-four cylinder engine. This engine is a key component of Toyota’s modern powertrain strategy, featuring both direct injection and multi-port fuel injection to optimize combustion efficiency and power delivery. The engine is turbocharged, with an intercooler to manage intake air temperature, resulting in a flat torque curve. The Dual VVT-i (Variable Valve Timing-intelligent) system further enhances performance and fuel economy by optimizing valve timing based on engine load and speed. Paired with this engine is Lexus’s 8-speed automatic transmission, marketed as ECT-i (Electronically Controlled Transmission – intelligent). This transmission is designed for smooth and responsive shifting, with adaptive shift logic that adjusts to driving conditions. The all-wheel-drive system employs a mechanically operated clutch to engage the rear wheels when traction is needed, providing enhanced stability and control.
Driving Characteristics
The RX 350 AWD ECT-i delivers a comfortable and refined driving experience. The 275 horsepower and 430 lb-ft of torque provide adequate acceleration, achieving 0-60 mph in approximately 7.2 seconds. While not a sports SUV, the turbocharger provides a noticeable boost in power during overtaking maneuvers. The 8-speed automatic transmission generally shifts smoothly, although some drivers may find it occasionally hesitant in certain situations. Compared to the hybrid RX 350h, the non-hybrid version offers a more traditional driving feel, with a more direct connection between the throttle and the engine. The all-wheel-drive system provides confident handling in various weather conditions, but it doesn’t offer the off-road capability of more rugged SUVs.
Equipment & Trim Levels
The RX 350 comes standard with a comprehensive suite of features, including a 12.3-inch touchscreen infotainment system, wireless Apple CarPlay and Android Auto compatibility, a premium sound system, and a suite of advanced driver-assistance systems (ADAS) such as Lexus Safety System+ 3.0. Interior upholstery typically consists of NuLuxe simulated leather, with available upgrades to genuine leather. Optional extras include a panoramic sunroof, heated and ventilated front seats, a Mark Levinson premium audio system, and a head-up display. Trim levels generally build upon the base model, adding features like larger wheels, upgraded interior trim, and additional safety technologies.
Chassis & Braking
The RX 350 utilizes a robust chassis with independent suspension at all four corners. The front suspension employs a McPherson strut design with coil springs and an anti-roll bar, while the rear suspension features a multi-link setup with a stabilizer bar. This configuration is tuned for comfort and stability, providing a smooth ride over various road surfaces. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock brakes (ABS) and electronic brake-force distribution (EBD) are standard features, enhancing safety and control.
Market Reception & Comparison
The Lexus RX 350 has consistently received positive reviews for its comfort, refinement, and reliability. Critics generally praise its spacious interior, user-friendly technology, and strong resale value. Compared to its competitors, such as the Acura MDX and BMW X5, the RX 350 often stands out for its quiet cabin and comfortable ride. Fuel economy is competitive within its class, achieving around 24 mpg combined. However, some reviewers note that its driving dynamics are not as sporty as some of its European rivals. The RX 350h hybrid variant offers superior fuel economy, while the upcoming RX 450h+ plug-in hybrid provides even greater efficiency and electric range.
Legacy
The T24A-FTS engine and the 8-speed automatic transmission are proving to be reliable powertrains in early reports. Lexus has a strong reputation for building durable vehicles, and the RX 350 is expected to maintain that tradition. On the used car market, the fifth-generation RX 350 is anticipated to hold its value well, thanks to its luxury brand reputation and strong reliability record. The combination of a turbocharged engine, smooth transmission, and all-wheel drive makes this variant a compelling choice for buyers seeking a comfortable and capable luxury crossover SUV.
