Infiniti QX50 2018 Review: VC-Turbo, Interior, Value

The 2018 Infiniti QX50 marks a significant evolution for Infiniti’s midsize luxury SUV lineup, introducing groundbreaking technology and a redesigned platform aimed at competing with established players like the BMW X3 and Audi Q5. This model ditches the outdated foundations of its predecessor for a modern transverse-engine architecture, promising enhanced efficiency, space, and driving refinement. With its striking angular aesthetics and advanced powertrain, the QX50 seeks to carve out a niche in a crowded segment dominated by German marques.

Redesigned Exterior: Aggressive Styling Meets Practicality

The QX50’s exterior design adopts a sharp, muscular profile that stands out from the softer lines of its rivals. The front fascia features a bold grille flanked by slim LED headlights, creating an imposing yet elegant presence. Proportions have shifted dramatically from the previous rear-drive-based model, with a wider stance and shorter overhangs that improve stability and visual balance.

Wheel options range from 18-inch alloys on base trims to 20-inch units on higher versions, enhancing its premium appeal. The side profile highlights flared wheel arches and a coupe-like roofline that tapers gracefully, though it maintains good rear headroom visibility. At the rear, full-width taillights and a sculpted tailgate emphasize modernity. Available in front-wheel or all-wheel drive, this setup suits varied climates and driving needs.

• Key design highlights: Angular creases for dynamic look, improved aerodynamics, and LED lighting across trims.
• Dimensions: Length around 4.7 meters, providing a compact footprint with generous interior volume.
• Colors: Vibrant options like Dynamic Sunstone Red and Majestic White accentuate its bold character.

Powertrain Innovation: The VC-Turbo Engine Revolution

Central to the QX50’s appeal is Infiniti’s variable compression turbo (VC-Turbo) 2.0-liter four-cylinder engine, a world-first technology that dynamically adjusts compression ratios for optimal power and efficiency. In high-performance mode, it drops to a low 8:1 ratio, delivering 268 horsepower and 380 Nm of torque. For cruising, it rises to 14:1, boosting fuel economy without sacrificing responsiveness.

Paired with a smooth eight-speed automatic transmission, acceleration is brisk: 0-62 mph in 6.7 seconds, with a top speed of 143 mph. This outperforms many naturally aspirated rivals while promising better real-world mpg figures. No diesel options are planned, positioning this petrol unit as the global standard. Drive modes including Eco, Sport, and Snow allow tailoring to conditions, with all-wheel drive enhancing traction.

Owners report the engine’s smoothness and lack of turbo lag, making highway merges effortless even fully loaded. Noise-vibration-harshness measures keep the cabin serene.

Interior Comfort: Spacious and Tech-Rich Cabin

Inside, the QX50 prioritizes luxury with high-quality materials like hand-stitched leather, Alcantara accents, and soft-touch plastics rivaling European counterparts. The dashboard mirrors the Q50 saloon’s layout, featuring dual touchscreens: an upper 8-inch display for navigation and a lower 7-inch for infotainment and climate controls. Apple CarPlay and Android Auto integration ensures modern connectivity.

Rear seating offers ample legroom and headspace, a leap from the prior model, accommodating adults comfortably. Cargo capacity impresses at over 900 liters with seats folded, aided by a hands-free tailgate. Ambient lighting, a panoramic sunroof, and premium Bose audio elevate the ambiance. ProPilot Assist, an optional semi-autonomous system, handles steering and braking in traffic, reducing fatigue on long drives.

• Seating for five with supportive, wide chairs.
• Quiet cabin thanks to active noise cancellation.
• Ample storage cubbies and USB ports throughout.

Driving Experience: Comfort with Compromises

On the road, the QX50 excels in ride comfort, with suspension tuned to absorb bumps effectively, especially on AWD models tested in varied terrains. The electronic ‘drive-by-wire’ steering adjusts rapidly for precision, though it lacks feel at low speeds. Handling is composed, with minimal body roll in corners, but it falls short of the agile dynamics from BMW or Audi.

Braking is strong and progressive, and the transmission shifts seamlessly. Fuel economy hovers around 30 mpg combined in real-world tests, competitive for the class. However, some reviewers note a firmer ride on larger wheels and less engaging feedback compared to rivals.

Safety and Technology Features

The QX50 packs advanced driver aids as standard: forward collision warning, automatic emergency braking, blind-spot monitoring, and lane-keeping assist. Higher trims add adaptive cruise control and 360-degree cameras. Infiniti’s InTouch system provides over-the-air updates and remote app control. Crash test ratings from NHTSA and IIHS underscore its structural integrity, earning top marks for occupant protection.

Trims, Pricing, and Value Proposition

Starting below $40,000 in the US (UK pricing around £40,000), the QX50 undercuts key competitors while offering generous equipment. Base Pure includes leatherette seats and dual screens; Luxe adds real leather and navigation; Sensory brings premium audio and ProPilot. Top Pure trim nears £50,000 with all bells and whistles.

This pricing, combined with a seven-year warranty in some markets, bolsters its value against pricier Germans.

Rivals Comparison: How It Stacks Up

Against the BMW X3, the QX50 offers similar power but superior space at a lower cost, though it trails in handling sharpness. The Audi Q5 edges it in refinement and AWD grip, while the Lexus NX provides hybrid efficiency but less outright pace. Volvo XC60 excels in safety but feels less sporty.

Long-Term Ownership Insights

Long-term tests reveal reliability strengths, with the VC-Turbo proving durable over 365 days of mixed use. Maintenance costs align with luxury norms, and resale holds steady. Common praises include quietness on highways and family-friendly space; minor gripes involve infotainment quirks and optional ride firmness.

Pros and Cons at a Glance

• Pros: Innovative engine, spacious interior, competitive pricing, strong acceleration, advanced tech.
• Cons: Steering lacks feedback, firm ride on big wheels, infotainment learning curve, not as engaging as rivals.
