2015 Infiniti QX50 I (facelift 2015) Dimensions, Size & Specs

The curb weight of the Infiniti QX50 I facelift, covering model years 2015 to 2016, ranges between 1749 kg (3855 lbs) and 1843 kg (4062 lbs) depending on trim and equipment levels. The maximum permissible weight stands at 2305 kg (5083 lbs). This weight capacity considers passengers, cargo, and any additional equipment. The relatively moderate curb weight for an SUV of this size contributes to its handling agility and fuel efficiency, while the maximum weight rating ensures safe load-carrying capability.

The ride height or ground clearance of the Infiniti QX50 I facelift lies between 165 mm (6.5 inches) and 175 mm (6.9 inches). This clearance allows the SUV to perform reasonably well on mildly rough or uneven terrain while maintaining a stable driving experience on paved roads. Ground clearance in this range strikes a balance between off-road capability and on-road handling dynamics, ensuring the vehicle does not feel excessively tall or unstable.

The 2015-2016 Infiniti QX50 I facelift SUV comes equipped with rim sizes of 18 or 19 inches, depending on the trim level. Correspondingly, the tire sizes available are 225/55 R18 tires for the 18-inch rims and 245/45 R19 tires for the 19-inch rims. The tire and wheel selections influence ride comfort, road grip, aesthetics, and handling characteristics. Larger wheels with thinner tires tend to enhance sporty handling and appearance but might slightly compromise ride comfort.

The luggage compartment of the Infiniti QX50 I facelift (2015-2016) offers a cargo volume of 309 liters (approximately 10.9 cubic feet) with rear seats in place. This capacity is adequate for everyday errands, small family trips, or grocery shopping. However, for extended travel or carrying large items, folding down the rear seats expands the luggage space significantly, although exact expanded volume depends on the seat configuration. This cargo volume is typical for compact luxury SUVs of its generation.

Yes, the Infiniti QX50 I facelift, with its 4745 mm (186.8 inches) length, 1800 mm (70.9 inches) width, and 1613 mm (63.5 inches) height, fits comfortably within a standard residential garage. Most standard garages have dimensions roughly 6.1 meters (20 feet) in length and 3 meters (10 feet) in width, providing sufficient space for this SUV along with room to open doors and move around. Its manageable size ensures practicality for urban dwellers seeking a luxury SUV without parking constraints.

Compared to its predecessor, the Infiniti QX50 facelift of 2015 maintained a similar footprint but included subtle tweaks. The length of 4745 mm (186.8 inches) and width of 1800 mm (70.9 inches) were largely consistent with the prior generation, providing continuity in passenger space and cargo capacity. However, the facelift focused more on design refinement and updated features rather than major changes in physical dimensions. Weight remained in the same range (curb weight between 1749 and 1843 kg), reflecting comparable structural underpinnings and materials, with possible use of lighter components to offset added equipment.

In the 2015-2016 period, the Infiniti QX50 I facelift competed with luxury compact SUVs like the Audi Q5, BMW X3, and Mercedes-Benz GLC. Dimensionally, the QX50's length of 4745 mm (186.8 inches) is slightly longer compared to some competitors—BMW X3 (around 4648 mm) and Audi Q5 (around 4629 mm)—offering a bit more interior space and cargo capacity. Cargo volume of 309 liters is somewhat lower than rivals like the Audi Q5, but comparable to the BMW X3. Ride height and ground clearance are competitive, facilitating similar road manners. Overall, the QX50 strikes a balance of size, luxury, and maneuverability tailored for buyers seeking an elegant yet practical SUV.

The Infiniti QX50 facelift offers 18-inch rims with 225/55 R18 tires and 19-inch rims paired with 245/45 R19 tires. Generally, the 18-inch rim configuration with taller sidewall tires delivers a softer ride, better absorbing road imperfections for enhanced comfort during daily driving or longer trips. Meanwhile, the 19-inch rims with lower profile tires provide sharper handling and improved road feedback, appealing to drivers prioritizing sportier dynamics at the expense of slight ride harshness. Selecting the ideal setup depends on personal preference and typical driving conditions.

With its exterior length of 4745 mm (186.8 inches), width of 1800 mm (70.9 inches), and height of 1613 mm (63.5 inches), the Infiniti QX50 facelift offers a spacious interior tailored for passenger comfort. Rear passengers enjoy adequate legroom and headroom comparable to class standards, supported by thoughtfully contoured seats and elevated ground clearance that aids ingress and egress. The SUV’s cabin design also creates a feeling of openness, enhancing passenger comfort during commutes or long journeys. While the rear seating area provides comfort for adults, actual legroom and shoulder space align closely with competitors in the luxury compact SUV segment.
