The Infiniti FX30d stands out in the crowded luxury SUV market by prioritizing driving excitement over typical family-hauler practicality. Built on a platform shared with the Nissan 370Z sports car, this diesel-powered model delivers sports car-like handling in an all-wheel-drive SUV body, making it a compelling choice for enthusiasts seeking performance without sacrificing comfort.

Engine Power and Performance Dynamics

At the heart of the Infiniti FX30d is a 3.0-liter V6 turbodiesel engine, engineered with direct injection and a large single turbocharger. It produces 235 horsepower at 3,750 rpm and a robust 406 lb-ft (550 Nm) of torque available from just 1,750 rpm, providing strong low-end pull ideal for overtaking and highway cruising. Paired with a smooth seven-speed automatic transmission featuring magnesium paddle shifters, the power delivery feels seamless, with minimal turbo lag and responsive shifts that enhance the driving experience.

Acceleration is brisk for its class, achieving 0-60 mph in 8.3 seconds and a top speed of 132 mph. Reviewers note that while it may not match the outright power of some German rivals like the BMW X5 xDrive30d (180kW/520Nm) or Mercedes ML350 CDI (190kW/620Nm), the FX30d’s engine integrates so well with the chassis that it rarely feels underpowered in real-world scenarios.

Chassis and Handling Excellence

What truly sets the FX30d apart is its chassis, derived from the Nissan 370Z, which imparts a grounded, sports-car feel uncommon in SUVs. The all-wheel-drive system is rear-biased, promoting playful dynamics where the vehicle exits corners with enthusiasm and precision, much like a rear-wheel-drive coupe. This setup provides confident grip, allowing drivers to carry speed into bends without losing traction, though wind noise at higher speeds can intrude.

Higher trims like the S model enhance this further with 21-inch alloy wheels, Continuous Damping Control (CDC) adjustable for auto or sport modes, and active rear steering for sharper turn-in. Testers report that the FX30d corners with extreme precision, hammering in and out of turns rivaling smaller SUVs like the BMW X3, while maintaining composure over rough roads.

Design and Road Presence

The FX30d commands attention with its aggressive, muscular styling—low-slung roofline, bold creases, and wide stance give it massive road presence that turns heads more than most competitors. It’s large enough to intimidate lane-hoggers in the outside lane, yet its coupe-like silhouette differentiates it from boxier rivals. Inside, the cabin offers ample storage and seating for four adults comfortably (five is possible but snug), though the 410-liter boot struggles with bulkier items like full-size prams.

Luxury Features and Technology

Infiniti loads the FX30d with premium amenities, especially in S Premium guise. Key highlights include ventilated front seats, a 360-degree Around View Monitor for effortless parking, Bose 11-speaker audio system, and a 30GB hard drive for media storage. Unique touches like an integrated Michelin Guide provide dining and lodging recommendations, blending tech with lifestyle convenience.

Safety is comprehensive: forward collision warning, intelligent brake assist, lane departure prevention and warning, intelligent cruise control, and low-speed follow. These features, available for a modest upgrade, elevate the FX30d’s appeal in a safety-conscious market.

  • Infotainment: Intuitive interface with hard drive navigation and premium sound.
  • Comfort: Supportive seats with ventilation; ample cabin storage.
  • Safety Tech: 360-camera, adaptive cruise, collision mitigation.

Fuel Efficiency and Practicality

Despite its performance focus, the FX30d impresses with diesel efficiency, achieving 25-28 MPG in mixed driving—excellent for a 3.0-liter engine in a large SUV. This makes it a smart pick for long-distance travel where torque and economy align. Practicality is decent for couples or small families, but the boot’s limitations and rear-seat space favor driver-centric use over heavy hauling.

Rivals and Market Positioning

Infiniti launched the FX without diesel initially to cement a sporty image, a strategy that paid off with the FX30d’s arrival. It challenges BMW X5, Mercedes ML, and Porsche Cayenne by undercutting prices while matching or exceeding fun-to-drive credentials. The diesel’s growl mimics petrol engines, adding character without excessive clatter.

Even after high mileage, owners report reliability, though Infiniti’s brand struggles for recognition in Europe.
