INFINITI QX55: Complete Guide to Performance, Interior, Features, and Specs in 2026

The INFINITI QX55 is a luxury crossover SUV that combines the practicality of a compact crossover with the distinctive shape of a coupe. With its sloping roofline, standard all-wheel drive, turbocharged engine, premium interior, and advanced driver-assistance technology, the QX55 was designed for drivers who wanted something more distinctive than a conventional SUV.

For anyone researching the INFINITI QX55 in 2026, one detail is especially important: the QX55 is now a discontinued model. INFINITI confirms that the vehicle was available from 2021 through 2025, with the 2025 model year being its final production year. That makes the QX55 a used-vehicle option for 2026 buyers rather than a new model.

Despite its short production run, the QX55 offers an interesting combination of 268 horsepower, standard AWD, a variable-compression turbocharged engine, five-passenger seating, and coupe-inspired styling.

INFINITI QX55 Engine, Performance, and AWD System

At the center of the QX55 is a 2.0-liter VC-Turbo four-cylinder engine. The variable-compression technology allows the engine to alter its compression ratio according to driving demands, balancing performance and efficiency characteristics.

For the 2025 model year, the engine produces 268 horsepower at 5,600 rpm and 280 lb-ft of torque, with peak torque available from 1,600 to 4,800 rpm. The engine is paired with a continuously variable transmission (CVT) and standard all-wheel drive.

INFINITI lists an estimated 0–60 mph time of approximately 6.4 seconds and a top speed of approximately 137 mph.

The standard all-wheel-drive system is an important part of the QX55’s specification. Unlike some luxury compact crossovers that offer AWD only as an option, every QX55 uses AWD. This can provide additional traction in rain, snow, and other low-grip conditions.

The QX55 is not designed as an off-road SUV. Its primary purpose is comfortable road driving, commuting, highway travel, and delivering a more engaging experience through its turbocharged powertrain and responsive chassis.

QX55 Exterior Design and Coupe-Inspired Styling

The most recognizable feature of the INFINITI QX55 is its exterior design. Rather than using the upright profile of a traditional SUV, INFINITI gave the QX55 a pronounced coupe-style roofline.

The vehicle measures approximately 186.3 inches long, 74.9 inches wide, and 63.8 inches high, with a 110.2-inch wheelbase.

Its rear profile is particularly distinctive. The sloping roof transitions into a sculpted rear section, while INFINITI’s signature digital piano-key LED taillights give the vehicle a recognizable nighttime appearance. The design also includes a prominent grille, sculpted body surfaces, LED lighting, and available larger wheels depending on trim.

INFINITI also offered an available motion-activated liftgate, allowing the driver to access the cargo area without manually opening the hatch.

The result is a crossover that emphasizes style while retaining the practicality expected from a five-passenger SUV.

INFINITI QX55 Interior, Seating, and Cargo Capacity

Inside, the QX55 provides seating for up to five passengers. The cabin follows a cockpit-oriented design that places many controls within easy reach of the driver.

Official specifications list 39.9 inches of front headroom and 36.9 inches in the second row, while front legroom measures 39.6 inches and rear legroom reaches 38.7 inches. Total passenger volume is approximately 100.2 cubic feet.

Cargo capacity is another important consideration. The QX55 provides approximately 26.9 cubic feet behind the second row and up to 54.1 cubic feet with the second row folded.

The coupe-style roof naturally influences the shape of the rear cargo area and reduces some of the utility available in a more upright crossover. However, the folding rear seats allow owners to carry larger items when additional cargo space is needed.

Higher trims can add premium touches such as semi-aniline leather-appointed seating, open-pore maple wood trim, heated and climate-controlled front seats, and a head-up display. The Sensory grade was positioned at the top of the QX55 range and offered a more luxurious cabin specification.

Technology, Infotainment, and Driver Assistance

The QX55 uses INFINITI’s InTouch dual-screen infotainment system, consisting of upper and lower displays. Depending on model and equipment, the system provides navigation, media controls, smartphone integration, Bluetooth connectivity, SiriusXM, and access to connected services.

Apple CarPlay and Android Auto are available, while a Wi-Fi hotspot adds another connectivity option for passengers. The Sensory and Essential trims can also be equipped with a Bose premium audio system.

The QX55 also includes a broad collection of driver-assistance technology. Standard equipment includes forward-collision warning, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, and lane-centering assistance through ProPILOT Assist.

These systems are designed to assist the driver rather than replace attentive driving. Their availability and operation can vary depending on road conditions, vehicle settings, and the specific system involved.

QX55 Trim Levels and Luxury Features

The QX55 was offered in several trim configurations, with the range generally centered around LUXE, ESSENTIAL, and SENSORY grades.

The LUXE provides the foundation of the QX55 lineup while still offering substantial standard equipment. The ESSENTIAL trim adds additional convenience and premium features, while the SENSORY emphasizes luxury with upgraded leather, interior trim, and technology.

The SENSORY model is particularly recognizable for its available Monaco Red interior, semi-aniline leather-appointed seats, natural maple wood trim, advanced climate-control features, and available head-up display.

For used buyers in 2026, equipment can vary according to model year, packages, and individual vehicle configuration. Checking the original window sticker or VIN-specific equipment list is therefore useful when comparing QX55 examples.

2025 INFINITI QX55 and Its Discontinuation

The 2025 INFINITI QX55 was largely unchanged compared with previous versions, but it has historical importance because it became the final model year. INFINITI officially identifies the QX55 as a discontinued vehicle and states that production covered the 2021–2025 period.

Automotive reporting in January 2025 also documented INFINITI’s confirmation that the QX55 and QX50 would end production after the 2025 model year.

This means 2026 shoppers should approach the QX55 primarily as a used luxury crossover. Its discontinuation does not mean parts, servicing, or ownership support automatically disappear; however, buyers should consider the vehicle’s remaining warranty coverage, service history, mileage, and condition.

The QX55’s final-year status may also appeal to buyers who specifically want its distinctive coupe-like styling without purchasing a brand-new vehicle.

Fuel Economy, Dimensions, and Ownership Considerations

According to INFINITI’s published 2025 specifications, the QX55 has an estimated 22 mpg city, 28 mpg highway, and 25 mpg combined. It uses a 16-gallon fuel tank.

For a used QX55, maintenance history is particularly important because the vehicle’s VC-Turbo engine uses more complex technology than a conventional fixed-compression engine. Buyers should review oil-change records, inspect the transmission operation, check for warning lights, and examine the AWD system during a professional inspection.

A pre-purchase inspection is especially useful when buying a discontinued luxury vehicle. It can identify suspension wear, brake condition, fluid leaks, tire problems, electronic faults, and other issues before purchase.

The QX55 is also a relatively heavy compact crossover, with official specifications placing curb weight in the approximate 4,070–4,123-pound range, depending on configuration.
