The Infiniti FX30d, specifically the variant produced from 2012 to 2013 as part of the FX II (facelift) generation, represents a unique offering within the luxury crossover segment. Positioned as a mid-range trim, it brought diesel power and all-wheel drive to the FX lineup, primarily targeting European markets where diesel engines were – and continue to be – highly favored. This model aimed to provide a balance between performance, fuel efficiency, and luxury, appealing to buyers seeking a sophisticated and capable vehicle for both daily commuting and long-distance travel. The FX series, as a whole, was Infiniti’s entry into the burgeoning luxury crossover market, attempting to blend sporty handling with the practicality of a larger vehicle.

Powertrain & Engine Architecture
The heart of the FX30d is the V9X engine, a 3.0-liter V6 diesel. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A variable geometry turbocharger with an intercooler further enhances performance and efficiency. The engine produces 238 horsepower at 3750 rpm and a substantial 550 Nm (405.66 lb.-ft.) of torque at just 1750 rpm. This torque output is a key characteristic of diesel engines, providing strong low-end pulling power. The engine also incorporates a diesel particulate filter (DPF) to meet stringent Euro 5 emission standards. The engine is longitudinally mounted, sending power to all four wheels via Infiniti’s ATTESA E-TS all-wheel-drive system. The transmission is a seven-speed automatic, chosen for its smooth operation and ability to handle the engine’s torque.
Driving Characteristics
The FX30d’s driving experience is characterized by its relaxed and refined nature. The abundant low-end torque from the diesel engine makes for effortless acceleration in everyday driving situations. While not as overtly sporty as the gasoline-powered FX35 or FX50 models, the 30d still offers respectable performance, achieving 0-60 mph in around 7.9 seconds. The seven-speed automatic transmission contributes to a smooth and seamless driving experience, although it may not be as quick to downshift as some sportier transmissions. The ATTESA E-TS all-wheel-drive system provides excellent traction and stability in various weather conditions. The system normally operates in rear-wheel drive, but seamlessly engages the front wheels when slip is detected, enhancing grip and control.
Equipment & Trim Levels
The FX30d typically came well-equipped, reflecting its positioning as a luxury crossover. Standard features often included leather upholstery, power-adjustable front seats, a premium audio system, dual-zone automatic climate control, and a navigation system. Exterior features included alloy wheels, xenon headlights, and a power liftgate. Optional extras could include a panoramic sunroof, adaptive cruise control, and a rear-seat entertainment system. The interior design focused on providing a comfortable and upscale environment, with high-quality materials and a user-friendly layout.
Chassis & Braking
The FX30d utilizes a double wishbone suspension setup at the front and an independent multi-link suspension at the rear, both incorporating stabilizer bars to minimize body roll. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Front brakes measure 355mm, while rear brakes are 350mm. The vehicle is equipped with ABS (Anti-lock Braking System) and hydraulic power steering. The suspension tuning is geared towards providing a comfortable ride, although it still offers a reasonable level of handling competence.
Market Reception & Comparison
The FX30d was generally well-received by automotive critics, who praised its fuel efficiency, comfortable ride, and luxurious interior. However, some reviewers noted that the diesel engine lacked the refinement and responsiveness of the gasoline engines offered in the FX lineup. Compared to the FX35, the 30d offered better fuel economy but less outright performance. The FX50, with its V8 engine, provided significantly more power but at the expense of fuel efficiency. The FX30d appealed to buyers who prioritized fuel economy and torque over outright speed and sporty handling.
Legacy
The V9X diesel engine, while not without its complexities, has proven to be relatively reliable when properly maintained. Like all modern diesel engines, it requires regular servicing and the use of high-quality oil. The FX30d has maintained a reasonable level of popularity in the used car market, particularly among buyers seeking a luxurious and fuel-efficient crossover. However, potential buyers should be aware of the potential costs associated with maintaining a diesel vehicle, including DPF maintenance and potential injector issues. Overall, the Infiniti FX30d represents a compelling option for those seeking a unique and capable luxury crossover with a diesel powertrain.
