The Lexus TX 350, introduced in October 2023, represents Lexus’s entry into the three-row mid-size luxury SUV segment. Positioned as a practical and refined option within the TX lineup, the 350 variant serves as the gasoline-powered base model, offering a balance of performance, efficiency, and standard features. Built on the GA-K platform, shared with other Toyota and Lexus models, the TX aims to provide a comfortable and technologically advanced experience for families. The TX 350 is primarily targeted at the North American market, where demand for three-row SUVs remains strong.

Powertrain & Engine Architecture
The Lexus TX 350 is powered by the T24A-FTS, a 2.4-liter turbocharged inline-four cylinder engine. This engine is part of Toyota’s Dynamic Force engine family, known for its emphasis on thermal efficiency and power delivery. The T24A-FTS utilizes a combination of direct injection and multi-port fuel injection to optimize combustion under various driving conditions. It also features a twin-scroll turbocharger with intercooling, which helps to minimize turbo lag and provide a broader torque curve. The engine employs a DOHC (Double Overhead Camshaft) valvetrain with Variable Valve Timing-intelligent (VVT-i) technology, further enhancing efficiency and responsiveness. The engine is paired with an 8-speed automatic transmission, marketed by Lexus as ECT-i (Electronically Controlled Transmission – intelligent). This transmission is designed for smooth and efficient gear changes, and is calibrated to work seamlessly with the engine’s torque characteristics.
Driving Characteristics
The TX 350’s 275 horsepower and 317 lb.-ft. of torque provide adequate performance for everyday driving and highway cruising. While not a sports SUV, the turbocharger provides a noticeable boost in acceleration, particularly when merging or overtaking. The 8-speed automatic transmission contributes to a comfortable driving experience, with well-spaced gear ratios. Compared to potential higher-output variants or hybrid models within the TX lineup, the 350 offers a more relaxed and fuel-efficient driving experience. The front-wheel-drive configuration contributes to a slightly lower price point but may result in less traction in adverse weather conditions compared to all-wheel-drive models.
Equipment & Trim Levels
The TX 350 comes standard with a comprehensive suite of features, including Lexus Safety System+ 3.0, which incorporates advanced driver-assistance technologies such as Pre-Collision System with Pedestrian Detection, Lane Departure Alert with Intelligent Steering Assist, and Dynamic Radar Cruise Control. Interior features typically include premium synthetic leather upholstery, a 12.3-inch touchscreen infotainment system, wireless Apple CarPlay and Android Auto compatibility, and a premium sound system. Available options include genuine leather upholstery, a panoramic sunroof, heated and ventilated front seats, and a Mark Levinson premium audio system. Trim levels generally offer incremental upgrades in features and aesthetics.
Chassis & Braking
The TX 350 utilizes an independent suspension system, with McPherson struts at the front and a multi-link setup at the rear. This configuration is designed to provide a comfortable ride and stable handling. Stabilizer bars are included at both ends to reduce body roll during cornering. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The electronic power steering system offers a responsive and precise steering feel.
Market Reception & Comparison
The Lexus TX 350 has been generally well-received by critics for its comfortable ride, spacious interior, and advanced technology. Fuel economy figures of around 23 mpg combined are competitive within the mid-size luxury SUV segment. Compared to other gasoline-only models in its class, the TX 350 offers a compelling combination of value and features. However, some reviewers have noted that the driving experience is not as engaging as some of its European rivals. The TX 350’s primary competitors include the Acura MDX, Infiniti QX60, and Buick Enclave.
Legacy
As a relatively new model, the long-term reliability of the TX 350 remains to be seen. However, Lexus has a strong reputation for building durable and reliable vehicles, and the T24A-FTS engine has been used in other Toyota and Lexus models with generally positive results. The TX 350 is expected to hold its value well in the used car market, particularly among buyers seeking a practical and well-equipped three-row SUV with a proven track record of reliability.
