Powertrain & Engine Architecture
The RX 350 is powered by the T24A-FTS, a 2.4-liter turbocharged inline-four cylinder engine. This engine utilizes both direct injection and multi-port fuel injection, optimizing combustion efficiency and power delivery. The engine produces 275 horsepower at 6000 rpm and 430 Nm (317 lb-ft) of torque between 1700 and 3600 rpm. The turbocharger, coupled with an intercooler, helps to mitigate turbo lag and maintain consistent boost pressure. The engine features a dual Variable Valve Timing-intelligent (VVT-i) system, which dynamically adjusts valve timing for improved performance and fuel economy. Paired with the engine is an 8-speed automatic transmission, marketed by Lexus as ECT-i (Electronically Controlled Transmission – intelligent). This transmission is designed for smooth and responsive shifting, contributing to the overall refined driving experience.
Driving Characteristics
The RX 350 with the 2.4L turbo and 8-speed automatic delivers a comfortable and capable driving experience. Acceleration from 0-60 mph takes approximately 7.6 seconds. While not a sports SUV, the engine provides ample power for everyday driving and highway merging. The automatic transmission is well-tuned, offering smooth gear changes and a willingness to downshift when needed. Compared to potential higher-performance RX variants (if offered), this version prioritizes fuel efficiency and a relaxed driving style. The gear ratios are optimized for both acceleration and highway cruising, providing a balance between responsiveness and fuel economy. The front-wheel-drive configuration contributes to a slightly lower curb weight and improved fuel efficiency compared to all-wheel-drive models.
Equipment & Trim Levels
The RX 350 typically comes standard with a comprehensive suite of features, including Lexus Safety System+ 3.0, which incorporates pre-collision system with pedestrian detection, lane departure alert with intelligent steering assist, and dynamic radar cruise control. Interior features generally include premium synthetic leather upholstery, a 12.3-inch touchscreen infotainment system, and a nine-speaker audio system. Available options include genuine leather upholstery, a 14-inch touchscreen, a Mark Levinson premium sound system, and a panoramic sunroof. Trim levels often build upon the base model, adding features like heated and ventilated front seats, power-adjustable steering wheel, and advanced driver-assistance systems.
Chassis & Braking
The RX 350 utilizes an independent suspension system, with McPherson struts at the front and a multi-link setup at the rear. This configuration provides a comfortable ride and good handling characteristics. Stabilizer bars are included both front and rear to reduce body roll during cornering. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The inclusion of ABS (Anti-lock Braking System) enhances safety by preventing wheel lockup during hard braking. The electric power steering system offers precise and responsive steering feel.
Market Reception & Comparison
The Lexus RX 350 has consistently received positive reviews for its comfortable ride, luxurious interior, and strong reliability. Critics generally praise the 2.4L turbo engine for its smooth power delivery and improved fuel economy compared to older V6 engines. Compared to competitors like the Acura MDX and BMW X5, the RX 350 often stands out for its quiet cabin and user-friendly infotainment system. Fuel economy is competitive within its class, achieving around 25 mpg combined. Reliability is a key strength, with Lexus consistently ranking high in consumer reports and dependability studies.
Legacy
The T24A-FTS engine and 8-speed automatic transmission represent a significant step forward for the RX line, offering improved performance and efficiency. While long-term reliability data is still emerging for this specific powertrain combination, Lexus’s reputation for building durable and dependable vehicles suggests a positive outlook. The RX 350 is expected to hold its value well in the used car market, appealing to buyers seeking a luxury SUV with a proven track record of reliability and refinement. The combination of modern technology, a comfortable ride, and Lexus’s commitment to quality positions the RX 350 as a strong contender in the luxury crossover segment.
