2018 Infiniti QX80 (Z62, facelift 2017) Dimensions, Size & Specs

The Infiniti QX80 Z62 facelift has a curb weight ranging from 2560 to 2671 kg (5,644 to 5,887 lbs), depending on trim and equipment. Its maximum permissible weight or gross vehicle weight ranges between 3311 and 3402 kg (7,299 to 7,498 lbs). This weight class is typical for large luxury SUVs and reflects the vehicle’s robust construction, powerful drivetrain, and extensive safety and luxury features.

The QX80 provides 470 liters (16.6 cubic feet) of luggage capacity behind the rear seats, which is ample for everyday needs or moderate cargo. When the rear seats are folded down, the luggage capacity expands significantly to 2693 liters (95.1 cubic feet), allowing for the transportation of much larger items or bulkier cargo. This flexibility makes the QX80 suitable for families and those who need substantial cargo space on demand.

The standard wheel setup on the 2018 Infiniti QX80 Z62 facelift includes rims sized at 8.0J x 20 inches paired with tires sized 275/60 R20. This combination balances aesthetics, ride comfort, and off-road capability. Larger tires contribute to the vehicle’s ground clearance and stability while ensuring a smooth ride on paved roads and off-road terrain alike.

Standard residential garage sizes typically range around 2.4 to 3 meters (8 to 10 feet) in width, 4.8 to 6 meters (16 to 20 feet) in length, and 2.1 to 2.4 meters (7 to 8 feet) in height. Given the QX80’s dimensions—5339 mm (5.3 meters/17.5 feet) long, 2029 mm (2.03 meters/6.66 feet) wide, and 1925 mm (1.9 meters/6.3 feet) tall—it can fit in many standard garages but with limited extra room, especially lengthwise. Homeowners with smaller garages might find parking the QX80 tight, particularly regarding door-opening space and maneuverability.

The 2018 facelift of the Infiniti QX80 Z62 maintained the core dimensions of its predecessor, as the platform and body design largely remained consistent. While some styling updates and minor tweaks to vehicle weight and features were introduced, overall length (5339 mm), width (2029 mm), height (1925 mm), and interior space were preserved to continue delivering the spacious luxury SUV experience. The facelift focused more on aesthetic and technological enhancements rather than dramatic size changes.

The Infiniti QX80’s dimensions closely align with its segment rivals. For example, the Lexus LX typically measures around 5080 mm (200 inches) long, 1980 mm (78 inches) wide, and 1925 mm (75.8 inches) tall, slightly smaller in length and width than the QX80. The Cadillac Escalade, meanwhile, is larger, with lengths exceeding 5700 mm (224 inches) depending on the model year. The QX80's generous size provides a middle ground in the segment, offering expansive interior space and cargo capacity while remaining somewhat more manageable than the largest SUVs like the Escalade.

The Infiniti QX80 is designed primarily as a full-size luxury SUV with three rows of seating. It typically accommodates up to 7 or 8 passengers depending on whether the second row features captain’s chairs or a bench seat. The spacious interior emphasizes passenger comfort, especially in the front and second rows, with ample legroom, headroom, and shoulder room thanks to the vehicle’s wide and tall stature. This makes the QX80 ideal for large families or groups needing premium luxury and space.

The QX80 includes a ride height or ground clearance of 234 mm (9.2 inches), which is quite generous for a luxury SUV. This clearance allows it to handle uneven surfaces, shallow off-road trails, and snow-covered roads with confidence. Combined with a robust suspension, powerful V8 engine options, and advanced drivetrain technologies, the QX80 offers respectable off-road capabilities for a vehicle of its size and luxury focus, making it versatile for both urban and more rugged environments.

The 2018 facelift of the Infiniti QX80 introduced a number of upgrades focused on luxury, technology, and safety. These include enhancements to the infotainment system with larger, more responsive touchscreens, updated driver assistance features such as improved adaptive cruise control and lane departure warning, and interior refinements with higher-quality materials and improved ergonomics. These upgrades aimed to keep the QX80 competitive within the luxury SUV market by boosting convenience, comfort, and safety.
