2008 Infiniti G35x: The AWD Sports Sedan That Time Forgot
The 2008 Infiniti G35x represents a narrow yet compelling moment in automotive history, where Infiniti sought to blend all-weather capability with the agility of a sports sedan. Available for just a few model years, the "x" variant distinguished itself by marrying the G35’s smooth V6 with a rear-biased all-wheel-drive system. This article examines the engineering, performance, and legacy of this specific model year, providing a detailed analysis for the enthusiast and the curious buyer alike.
The decision to integrate all-wheel drive into the G line was strategic, aiming to attract drivers who desired the excitement of a rear-drive sport sedan without sacrificing confidence in inclement weather or on winding roads. While not a sales juggernaut, the G35x cultivated a dedicated following appreciative of its balance of comfort and capability. Understanding its nuances reveals a lot about Infiniti’s aspirations during the mid-2000s.
The Heart of the Matter: Powertrain and Dynamics
At the core of the 2008 G35x lies the same 3.5-liter VQ35HR V6 that powered its rear-wheel-drive siblings. This powerplant is renowned for its smooth power delivery, high-revving nature, and robust construction. Producing 303 horsepower and 262 lb-ft of torque, the engine provided ample thrust for daily driving and spirited back-road excursions. The addition of the all-wheel-drive system did not dilute this performance; rather, it redistributed the power to optimize traction.
The ATTESA E-TS Pro system, borrowed from Nissan’s performance arsenal, is the mechanism behind the G35x’s all-weather prowess. This system is fundamentally different from a simple "driver-selectable" mode found in some trucks. It is a permanent, intelligent all-wheel-drive system that actively monitors wheel slip and apportion torque between the front and rear wheels in milliseconds. Under normal conditions, the system biases power to the rear wheels, preserving the engaging driving dynamics expected of a sports sedan. When the rear wheels begin to lose grip, the system can send up to 50% of the available torque to the front wheels, effectively stabilizing the car.
This intelligent distribution is key to the G35x’s handling character. Unlike heavier, truck-based AWD vehicles that can feel cumbersome, the G35x maintains a relatively light and responsive chassis. The steering, while electric and lacking the raw feedback of a hydraulic system, is precise and provides good road feel. The suspension setup, featuring MacPherson struts in front and a multi-link independent rear suspension, strikes a balance between comfort and control. The result is a car that feels planted and stable at high speeds, yet nimble enough to carve through a series of corners without feeling overwhelmed by its drivetrain.
Design and Engineering Nuances
Visually, the 2008 Infiniti G35x can be distinguished from its rear-wheel-drive counterparts by several subtle cues. The most obvious is the badging; the trunk lid and rear fascia prominently feature an "x" badge. The alloy wheels were also specific to the model, often featuring a darker finish and a unique spoke design that complemented the car's assertive stance.
Under the skin, the changes were more significant but equally elegant. The addition of the center differential and the complex piping for the hydraulic clutch pack necessary for the ATTESA system required a reworked chassis subframe. Engineers had to carefully calibrate the suspension geometry to account for the additional weight and complexity of the AWD components, ensuring that the car’s center of gravity remained low and its weight distribution was as balanced as possible. This meticulous attention to detail is what allows the G35x to handle so adeptly, a fact often noted in contemporary automotive reviews.
Inside, the cabin is a sanctuary of Japanese luxury and sport-oriented design. The seats, bolstered with firm foam, provide excellent lateral support during aggressive cornering. The dashboard is dominated by a large, analog-style tachometer flanked by a digital read-out, a layout that prioritizes the driving experience. The materials used throughout the interior—soft-touch plastics, premium leather, and brushed aluminum accents—create an atmosphere that feels both refined and engaging. While the infotainment system may appear dated by modern standards, its function was straightforward and reliable, a testament to the era’s design philosophy.
Owning an Icon: Reliability, Maintenance, and Legacy
For the prospective buyer of a 2008 Infiniti G35x, understanding the car’s reliability and maintenance needs is paramount. The VQ35HR engine is generally considered a robust unit, capable of high mileage with proper care. Common issues are not catastrophic but require attention. These can include normal wear items like brake pads and rotors, as well as the gradual degradation of engine mounts and bushings, which are typical for any aging sports sedan.
The all-wheel-drive system introduces an additional component to monitor: the transfer case fluid. This fluid should be changed at manufacturer-recommended intervals to ensure the clutches and gears within the ATTESA system remain lubricated and functional. Neglecting this maintenance can lead to premature wear and costly repairs. Electrical gremlins, while not unique to the G35x, are a consideration in any car of this age, and a pre-purchase inspection by a mechanic familiar with Infinitis is highly recommended.
Despite these considerations, the G35x has earned a reputation as a driver’s car that delivers on its promises. It offers a blend of performance, comfort, and all-weather usability that few competitors in its class could match at the time. For the enthusiast, it represents a relatively affordable entry point into the world of Japanese performance sedans with a genuine all-weather advantage. Its legacy is that of a sophisticated and engaging machine that proved all-wheel drive could coexist with sporty driving dynamics without compromise.
Performance Metrics and Real-World Driving
While numbers on a spec sheet provide a baseline, the true measure of the 2008 G35x is found behind the wheel. Acceleration from 0 to 60 mph is typically in the mid-to upper-6-second range, a figure that was respectable for the era and feels brisk in real-world driving. The top speed is electronically limited to around 130 mph, a testament to the engine’s power and the car’s stability.
The AWD system shines in its everyday application. Drivers in regions with frequent rain, light snow, or even just on winding mountain roads will find immense confidence in the car’s grip. The system’s ability to send power to the front wheels during a skid is not about enabling reckless cornering but about maintaining control and stability. It transforms a car that might once have been a liability in poor weather into a safe and competent daily driver. The G35x doesn't encourage pushing its limits in extreme conditions, but it provides the safety net to get you home safely when conditions deteriorate.
