The Infiniti FX II, specifically the 35 V6 model produced from 2011 to 2013, represents a significant refresh of the first-generation FX crossover. Positioned as a mid-range offering within the FX lineup, this variant aimed to balance performance and luxury with a more accessible price point than the higher-trim FX50. The 2011 facelift brought revised styling, enhanced interior materials, and subtle improvements to the ATTESA E-TS all-wheel-drive system. It competed directly with luxury crossovers like the BMW X6, Acura ZDX, and Porsche Cayenne, offering a distinctive blend of Japanese engineering and American market sensibilities.

Powertrain & Engine Architecture
The heart of the 2011-2013 Infiniti FX35 is the VQ35HR 3.5-liter V6 engine. This engine, a member of Nissan’s highly regarded VQ family, is known for its smooth operation and robust reliability. The “HR” designation signifies “High Revolution,” indicating a focus on increased power output at higher engine speeds. The VQ35HR utilizes a 60-degree V-angle, dual overhead camshafts (DOHC) with continuously variable valve timing control system (CVVTCS) on both intake and exhaust valves, and multi-port fuel injection. The engine produces 303 horsepower at 6800 rpm and 261 lb-ft of torque at 4800 rpm. The engine is longitudinally mounted, driving all four wheels through a seven-speed automatic transmission. This transmission, while generally smooth, isn’t known for particularly quick shifts compared to some competitors. It features adaptive shift control, attempting to learn the driver’s habits and adjust shift points accordingly.
Driving Characteristics
The FX35’s driving experience is characterized by a comfortable ride and capable handling. The 303 hp V6 provides adequate acceleration for most driving situations, though it doesn’t offer the outright performance of the FX50’s V8. The seven-speed automatic transmission, while smooth, can feel somewhat hesitant during quick overtaking maneuvers. The ATTESA E-TS all-wheel-drive system is primarily rear-wheel drive biased, providing a sporty feel, but can seamlessly shift power to the front wheels when traction is needed. The gear ratios are tuned for a balance of fuel economy and responsiveness, but the engine can feel strained when pushed hard. Compared to a manual transmission equipped FX (not offered in the US market for this generation), the automatic sacrifices some driver engagement for ease of use.
Equipment & Trim Levels
The 2011-2013 Infiniti FX35 came standard with a generous array of features, including leather upholstery, power-adjustable front seats, a rearview camera, a Bose audio system, and automatic climate control. Optional extras included a navigation system, a panoramic sunroof, adaptive cruise control, and lane departure warning. Interior trim levels varied, with options for wood or aluminum accents. The FX35 generally featured a more restrained interior aesthetic compared to the FX50, focusing on comfort and functionality rather than outright luxury.
Chassis & Braking
The FX35 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. Braking duties are handled by ventilated discs on all four wheels, with ABS standard. The FX35’s suspension is tuned for a comfortable ride, prioritizing smoothness over razor-sharp handling. The braking system is adequate for everyday driving, but the FX50’s larger brakes offer more stopping power.
Market Reception & Comparison
Critics generally praised the FX35 for its stylish design, comfortable interior, and capable all-wheel-drive system. However, some reviewers noted that the engine could feel underpowered compared to competitors, and the transmission lacked the responsiveness of some other luxury crossovers. Fuel economy was also a point of criticism, with the FX35 achieving relatively low MPG figures for its class. Compared to the FX50, the FX35 offered a more affordable entry point into the FX lineup, but at the expense of performance and some luxury features. The FX35 appealed to buyers who prioritized comfort and style over outright speed.
Legacy
The VQ35HR engine has proven to be remarkably durable, with many examples exceeding 200,000 miles with proper maintenance. The seven-speed automatic transmission, while not without its quirks, is also generally reliable. On the used car market, the 2011-2013 Infiniti FX35 represents a good value proposition, offering a luxurious and capable crossover at a relatively affordable price. However, potential buyers should be aware of potential issues with the timing chain tensioners and oil consumption, which are common concerns with the VQ35HR engine. Overall, the FX35 remains a popular choice for those seeking a distinctive and reliable luxury crossover.
