Infiniti FX50S Premium Review: 5.0L V8, 390 Hp Performance

The Infiniti FX50S Premium stands out as a bold fusion of sports car agility and SUV versatility. Powered by a robust 5.0-liter V8 engine producing 390 horsepower, this model delivers exhilarating acceleration while offering premium comfort and advanced safety systems. Launched around 2013, it targets drivers seeking a distinctive alternative to mainstream luxury crossovers.

Design and Exterior Highlights

The FX50S Premium boasts an aggressive, coupe-like silhouette inspired by high-performance coupes, with a sloping roofline and wide stance that commands attention. Its 21-inch alloy wheels wrapped in 265/45 tires enhance its muscular presence, complemented by chrome accents and adaptive bi-xenon headlights for superior night visibility. Functional vents behind the front wheels not only aid aerodynamics but also underscore its performance-oriented engineering.

Available in striking colors, the bodywork includes a power liftgate for easy access to the cargo area, which offers 24.8 cubic feet of space behind the rear seats. The all-wheel-drive system ensures confident handling across varied conditions.

Engine Performance and Drivetrain

At the heart lies the 5.0-liter V8 engine with Variable Valve Event and Lift (VVEL) technology, generating 390 hp and 500 Nm of torque. Paired with a seven-speed automatic transmission featuring adaptive shift control, it propels the roughly 4,546-pound vehicle from 0-100 km/h in about 5.8 seconds, with a quarter-mile in 13.6 seconds at 104 mph, topping out at a governed 155 mph.

The ATTESA E-TS all-wheel-drive system prioritizes rear-wheel bias for sporty dynamics, switching to full-time AWD when needed. Fuel economy stands at around 13.1 L/100km combined, typical for its power class. Towing capacity reaches 3,500 pounds, making it practical for light duties.

Chassis and Handling Dynamics

Equipped with continuous damping suspension in sport mode, the FX50S Premium adjusts to road conditions for a balance of comfort and control. Rear Active Steer subtly angles rear wheels for sharper turning and stability at high speeds. Large four-piston front brake calipers deliver strong stopping power, aided by ABS, electronic brakeforce distribution, and brake assist.

Drive modes include snow settings, and the sport package adds self-leveling headlights. Reviewers note its BMW X6-like poise, blending rapid straight-line speed with composed cornering despite the two-tonne weight.

Interior Comfort and Luxury

Inside, the cabin features high-quality leather seats with quilted inserts, heated and ventilated fronts with 14-way power adjustments and memory settings. Dual-zone climate control, a tilt-telescopic steering wheel with audio/cruise buttons, and a reclining rear bench accommodate five passengers comfortably.

Wood and piano black trims elevate the ambiance, while road noise insulation ensures a serene ride. The power liftgate and keyless entry/start add convenience.

• Climate-controlled front seats
• Multi-level heating for driver/passenger
• Rear height-adjustable headrests
• USB/aux inputs with external media control

Infotainment and Technology Suite

The 11-speaker Bose premium audio system, with 300 watts and subwoofers, delivers immersive sound. Hard disk navigation includes real-time traffic, music storage, Bluetooth, and satellite radio (3 months free). Speed-sensitive volume and diversity antenna enhance usability.

Though dated by modern standards, the system supports USB for MP3 players and offers intuitive controls below the navigation display.

Safety Innovations

Earning top marks, the FX50S Premium includes a 5-star ANCAP rating where tested, with features like active front head restraints, side-impact and curtain airbags, traction control, stability control, and tire pressure monitoring.

The around-view monitor uses four cameras for a bird’s-eye parking view, crucial given the high dashboard and limited rear sightlines. Additional aids: forward collision warning, lane departure prevention, adaptive cruise, and intelligent brake assist that pre-applies brakes in emergencies.

Packages and Customization Options

The Premium pack bundles essentials like 21-inch wheels, around-view monitor, and advanced driver aids. Additional options include Technology Package ($2,900), Deluxe Touring ($1,650), Sport Package ($3,000) with active dampers, Tow Package ($695), and minor add-ons like first aid kits.

Warranty covers 4 years/100,000 km or 60,000 miles. The S variant primarily adds suspension and rear steering over base FX50.

Ownership Experience and Reliability

Owners praise the V8’s thrust and luxury, though chrome flaking and higher fuel costs are noted drawbacks. Maintenance requires attention to the premium components, but the build quality holds up well. It’s a rare sight today, appealing to enthusiasts valuing uniqueness over efficiency.

Compared to rivals like Porsche Cayenne or BMW X6, it offers similar performance at potentially lower used prices, though resale may lag due to Infiniti’s niche status.

Pros and Cons

• Pros: Blistering V8 acceleration, loaded safety tech, premium Bose audio, agile handling
