Ever since Infiniti changed the names of all its models to either Q or QX, telling its vehicles apart has required either a good memory or a cheat sheet. Here we’ll outline all the differences you need to know between three of its most popular SUVs, the Infiniti QX50, Infiniti QX55, and Infiniti QX60.
Infiniti QX50 vs. QX55 vs. QX60: Background, Size and Segment
Introduced in its current generation in 2019, the QX50 is a two-row compact SUV, and it’s currently the entry-level SUV in Infiniti’s lineup. The QX50 has two rows of seats providing room for five, with no third-row seat available. Competitors include the Genesis GV70 and Acura RDX.
The QX55, first introduced in 2022, is closely related to the QX50; the primary difference is its fast coupe-style roofline, similar to the BMW X4, Mercedes-Benz GLC Coupe, and Audi Q5 Sportback. Although German automakers build “coupe” versions of their SUVs, Infiniti is one of the only Japanese brands to do so.
The QX60, the current generation of which was introduced in 2022, is a larger vehicle with three rows of seats accommodating up to seven people. A relative of the Nissan Pathfinder, the QX60 competes with larger SUVs like the Volvo XC90 and Audi Q7.
Infiniti QX50 vs. QX55 vs. QX60: Interior Amenities
Infiniti is positioned as a luxury brand, and all three of these SUVs have the high-class interiors you’d expect. The base model of the QX50 offers faux-leather seating surfaces; all other QX50s, and all QX55 and QX60 models, have genuine leather, which is padded and quilted in top-of-the-line models. (The third-row seat in the QX60 uses leatherette.)
All three models offer heated, power-adjustable front seats, with a ventilation function in higher trim levels. Heated second-row seats and a heated steering wheel are available in all models, and interior ambient lighting comes standard. QX50 and QX55 models come standard with a dual-zone climate control system, while an optional tri-zone system allows rear-seat passengers to set their own temperature. Tri-zone climate control is standard in the QX60.
Infiniti QX50 vs. QX55 vs. QX60: Seating and Passenger Space
Both the QX50 and QX55 are five-seaters, though the QX55’s fastback compromises rear-seat headroom, as the chart below shows. The QX60 is a seven-seater, though the top-of-the-line QX60 Autograph model has second-row bucket seats instead of a three-place bench, reducing seating capacity to six. The QX60 has tighter accommodations in its second row compared to the QX50 and QX55, and its two-place third-row seat is best suited for small children.
Infiniti QX50 vs. QX55 vs. QX60: Cargo Space
All three of these SUVs have a usable amount of cargo space behind the second row, while the QX55’s faster roofline lowers cargo volume. (That said, the deep slant of the rear bodywork may make it easier to load bulky items.) The QX60 has additional cargo space compared to the QX50 and QX55, though deploying the third row reclaims a lot of that room. All three of these Infiniti SUVs have fold-down second-row seats to further expand luggage capacity.
Infiniti QX50 vs. QX55 vs. QX60: Powertrain, Suspension, Fuel Economy
The QX50, QX55, and QX60 share an engine, the 2.0-liter VC Turbo four-cylinder, which uses Nissan’s innovative variable-compression system. (We’ll spare you the in-depth technical explanation, which you can find here; the short version is that the VC-Turbo varies the compression ratio to maximize either power or fuel economy depending on driving conditions.) Engine output is identical in the QX50 and QX55, while the QX60 produces slightly more torque to offset its increased weight.
The transmissions used in these Infiniti SUVs differ from one another. Both the QX50 and QX55 use a continuously variable automatic transmission (CVT), which infinitely varies the ratio between the engine and drive wheels to provide smooth, shift-free acceleration. The QX60 uses a more conventional nine-speed automatic transmission. The QX60 offers both front- and all-wheel drive, while the QX50 and QX55 come with all-wheel drive as standard. (Infiniti did offer a front-wheel-drive version of the QX50, but it was dropped for the 2025 model year.) Because of its larger size and mass, the QX60 is slightly less fuel-efficient than the QX50 and QX55.
Infiniti QX50 vs. QX55 vs. QX60: Safety and Driver Assistance Technology
The QX50 and QX55 offer a similar suite of safety and advanced driver assistance systems (ADAS). These include front and rear collision detection and warning with automatic braking, blind-spot and rear cross-traffic alerts, lane departure warning and correction, and adaptive cruise control that will bring the vehicle to a full stop. Infiniti’s ProPilot Assist system, which will steer the SUV on the open road (the driver must keep their hand on the wheel), is also standard. Rain-sensing wipers, traffic sign recognition, and a 360-degree bird’s-eye parking camera are optional.
The QX60 offers a lower-spec Pure model that comes with fewer of these features. All QX60s have front and rear collision detection with automatic braking, blind-spot and rear cross-traffic alerts, and a lane departure warning system. Additional ADAS and safety equipment, including lane departure and blind-spot intervention, drowsy driver detection, adaptive cruise control, a bird’s-eye parking camera, traffic sign detection, and ProPilot Assist are standard on the Luxe, Sensory, and Autograph models. Additionally, the QX60’s ProPilot Assist system links to the navigation system and can automatically adjust to speed limits and slow for sharp curves.
Infiniti QX50 vs. QX55 vs. QX60: Infotainment
Here again, the QX50 and QX55 have similar offerings. Both have an infotainment system that uses two screens, one of which is always controlled by the car while the other can be taken over by Apple CarPlay (with wireless support) or Android Auto. The stereo system has AM, FM, and SiriusXM satellite radio, Bluetooth streaming, and—nostalgia time!—a CD player. Base models have six speakers, and a 16-speaker Bose system comes with higher trim levels. The QX50 also offers a12-speaker Bose system in some intermediate trims. There are four USB ports, with a USB-A and USB-C port in each row of seats.
The QX60 uses a newer single-screen infotainment system with a 12.3-inch touchscreen display. The standard stereo has AM/FM/XM/Bluetooth capability (but, sorry, no CD player), while a 17-speaker Bose system comes in higher trim levels.
Pricing
The QX50 is positioned as Infiniti’s entry-level SUV, though pricing is comparable with other two-row luxury SUVs. The QX55 has a higher price point due to its more generous standard equipment, while the QX60, as a larger vehicle, is priced higher than its stablemates. Pricing for the three SUVs, as of model year 2025, is as follows:

Infiniti QX50 vs. QX55 vs. QX60: Which One Should You Buy?
These three Infiniti models are aimed at three distinct audiences. If your kids are very small, out of the house, or nonexistent, the QX50 is a good choice, sized to provide a good compromise of passenger and cargo space with easy maneuverability. If you want something a little more unique-looking, the fastback QX55 cuts a stylish profile, though it compromises on back-seat headroom and (to a lesser extent) cargo space. If you have more than two kids or participate in the school carpool, the QX60 will provide more flexibility for passengers as well as extra cargo space for big family vacations. If your passenger load consists of more than four adults, you may want to consider a larger full-size SUV like the Infiniti QX80.
