Powertrain & Engine Architecture
The heart of the IS 350 AWD is the 2GR-FKS 3.5-liter naturally aspirated V6 engine. This engine utilizes both direct injection (D-4S) and port injection to optimize combustion efficiency and power delivery. The direct injection system injects fuel directly into the combustion chamber, while the port injection system provides supplemental fuel during high-load conditions. The engine features a dual overhead camshaft (DOHC) design with intelligent variable valve timing (D-VVT-i) on both intake and exhaust valves, further enhancing performance and fuel economy. The 2GR-FKS produces 311 horsepower at 6,400 rpm and 277 lb-ft of torque at 4,800 rpm. This engine is paired with a six-speed automatic transmission (ECT – Electronically Controlled Transmission) specifically tuned for smooth and responsive shifting. The AWD system employs a viscous coupling center differential, distributing torque between the front and rear axles as needed to maintain optimal traction.
Driving Characteristics
The IS 350 AWD delivers a noticeably more engaging driving experience than its turbocharged four-cylinder counterparts. The naturally aspirated V6 provides a linear power delivery, offering strong acceleration throughout the rev range. While not as fuel-efficient as the smaller engine options, the IS 350’s performance is rewarding. The six-speed automatic transmission is well-matched to the engine’s characteristics, providing quick and precise shifts. The AWD system enhances stability and grip, particularly in inclement weather conditions. The gear ratios are tuned for a balance of acceleration and highway cruising, with a focus on providing responsive power for overtaking maneuvers. Compared to the IS 200t/300, the IS 350 feels significantly more powerful and refined.
Equipment & Trim Levels
The IS 350 typically came well-equipped with standard features including leather upholstery, heated and ventilated front seats, a premium audio system, a navigation system, and a suite of advanced safety technologies such as Lexus Safety System+. Optional extras included a Mark Levinson premium sound system, adaptive variable suspension, and a power rear sunshade. Interior trim options included various wood and metallic accents. The IS 350 was generally offered in a single, fully-equipped trim level, with options primarily focused on enhancing the luxury and convenience features.
Chassis & Braking
The IS 350 utilizes a robust chassis with a double-wishbone front suspension and an independent multi-link rear suspension. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated disc brakes on all four wheels, providing ample stopping power. The front brakes measure 334mm in diameter, while the rear brakes are 310mm. An Anti-lock Braking System (ABS) is standard, along with Electronic Brake-force Distribution (EBD) and Brake Assist.
Market Reception & Comparison
Critics generally praised the IS 350 for its powerful engine, comfortable ride, and luxurious interior. However, some noted that the six-speed automatic transmission felt dated compared to the eight or nine-speed automatics offered by competitors. Fuel economy was also a point of criticism, as the IS 350’s consumption was higher than that of its turbocharged rivals. Compared to the IS 200t/300, the IS 350 offered a significant performance upgrade, but at a higher price point. The IS 350 competed primarily with the BMW 335i/340i, Audi A4 3.0T, and Mercedes-Benz C350.
Legacy
The 2GR-FKS engine has proven to be a reliable and durable powerplant, with relatively few widespread issues reported. The IS 350’s AWD system is also generally considered to be robust and dependable. On the used car market, the IS 350 holds its value relatively well, particularly well-maintained examples with low mileage. Its combination of luxury, performance, and all-weather capability continues to appeal to buyers seeking a refined and capable sports sedan. Regular maintenance, including oil changes and fluid checks, is crucial for ensuring the long-term reliability of this powertrain.
