The Infiniti FX35, specifically the second-generation model (designated FX II, built from 2008-2011), represented a significant step forward for the brand in the burgeoning luxury crossover segment. Positioned as a performance-oriented alternative to more traditional SUVs, the FX35 aimed to deliver a blend of sporty handling, robust all-wheel drive capability, and a luxurious interior. This variant, equipped with the 3.5-liter V6 engine and a seven-speed automatic transmission, served as the volume leader in the FX lineup, offering a compelling balance between performance and price. It competed directly with vehicles like the BMW X5, Acura MDX, and Porsche Cayenne, though with a distinct emphasis on styling and a more aggressive driving experience.

Powertrain & Engine Architecture
The heart of the FX35 is Nissan’s VQ35HR 3.5-liter V6 engine. This engine, a member of the highly-regarded VQ family, is known for its smooth operation, robust construction, and willingness to rev. The “HR” designation signifies “High Revolution,” indicating enhancements to the engine’s valvetrain and intake system for improved high-speed performance. It features a 60-degree V-angle, dual overhead camshafts (DOHC) with continuously variable valve timing (CVTCS) on both intake and exhaust sides, 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, sourced from Aisin, offers manual shift control and adaptive learning to optimize shift points based on driving style. The ATTESA E-TS (Advanced Total Traction Engineering System for All-Terrain) all-wheel-drive system is a key component, providing a rear-wheel-drive bias under normal conditions and seamlessly distributing torque to the front wheels when slip is detected.
Driving Characteristics
The FX35 with the 3.5L V6 and automatic transmission delivers a responsive and engaging driving experience. While not as overtly sporty as some of its European rivals, it offers ample power for everyday driving and confident acceleration for highway passing. The seven-speed automatic transmission is generally smooth and quick-shifting, although some drivers noted a slight hesitation during kickdown. The ATTESA E-TS system provides excellent traction in a variety of conditions, enhancing stability and confidence. Compared to the FX35 with a manual transmission, the automatic version sacrifices some driver involvement but gains in ease of use and refinement. The gear ratios are tuned for a balance of acceleration and fuel economy, with a relatively tall final drive.
Equipment & Trim Levels
The FX35 typically came well-equipped, even in its base form. Standard features included leather upholstery, power-adjustable front seats, a Bose premium sound system, a rearview camera, and automatic climate control. Optional extras included a navigation system, power-folding rear seats, adaptive cruise control, and a panoramic sunroof. Trim levels were relatively simple, with most variations coming down to the addition of option packages. Interior materials were generally high quality, with a focus on creating a luxurious and comfortable cabin environment.
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 at both ends to reduce body roll during cornering. The braking system consists of ventilated discs on all four wheels, with ABS (Anti-lock Braking System) as standard. The FX35’s suspension tuning prioritizes comfort and stability, providing a relatively smooth ride over most road surfaces. The steering is hydraulically assisted, offering a good balance of feel and responsiveness.
Market Reception & Comparison
The Infiniti FX35 was generally well-received by automotive critics, who praised its distinctive styling, comfortable interior, and strong performance. However, some reviewers noted its relatively poor fuel economy compared to other crossovers in its class. The automatic transmission was generally considered competent, but not as engaging as the available manual transmission. Compared to the FX45 (equipped with a 4.5-liter V8), the FX35 offered a more affordable entry point into the FX lineup, albeit with less power. The FX35’s fuel economy averaged around 18 mpg combined, which was below average for the segment at the time.
Legacy
The Infiniti FX35 (specifically the VQ35HR engine and 7-speed automatic combination) has proven to be a relatively reliable powertrain. The VQ35HR engine is known for its durability, and with proper maintenance, can easily exceed 200,000 miles. Common issues include oil consumption (particularly in earlier model years) and potential failure of the cooling system components. On the used car market, the FX35 remains a popular choice for buyers seeking a stylish and capable crossover at a reasonable price. Its distinctive design and comfortable interior continue to appeal to a wide range of drivers. While newer crossovers offer more advanced technology and improved fuel economy, the FX35 retains a loyal following and is considered a modern classic by many enthusiasts.
