2014 Infiniti QX50 I Dimensions, Size & Specs

With the mirrors fully opened, the Infiniti QX50 I reaches a width of 2043 mm (80.4 inches). This wider measurement is crucial when considering parking space requirements, navigating tight areas, or passing through narrow spaces. The increased width due to the mirrors affects maneuverability and should be considered especially in urban environments or tight garages.

The curb weight of the Infiniti QX50 I ranges from 1842 to 1985 kg (4060 to 4375 lbs), while the maximum gross weight ranges between 2272 and 2470 kg (5009 to 5444 lbs). This weight influences fuel efficiency, acceleration, and handling. The substantial curb weight provides a sense of stability and safety, whereas the maximum weight includes passengers and cargo, making it essential to avoid overloading for optimal performance and safety.

The ride height or ground clearance of the Infiniti QX50 I is between 147 mm to 149 mm (5.8 to 5.9 inches). This moderate ground clearance allows for comfortable everyday driving on paved roads and some light off-road or uneven surface capability, though it is not designed for heavy off-roading. It generally enables the vehicle to clear minor obstacles and speed bumps with ease.

The Infiniti QX50 I offers a luggage capacity of 309 liters (10.9 cubic feet) with the rear seats in place, suitable for everyday errands and small trips. When the rear seats are folded down, the cargo space expands significantly to 1175 liters (41.5 cubic feet), providing ample space for larger items, luggage, or equipment, ideal for road trips or moving bulkier goods.

The Infiniti QX50 I is equipped with 18-inch rims paired with 225/55 R18 tires. This combination balances ride comfort, traction, and handling performance. The tire size ensures a smooth ride over various road surfaces and supports the SUV's weight and size, contributing to its stability and road grip.

Yes, the Infiniti QX50 I fits comfortably into a standard single-car garage. Typical single-car garages have widths ranging from 2400 to 3000 mm (94.5 to 118 inches) and lengths of about 5400 to 6000 mm (212.6 to 236 inches), so with a width of 1800 mm (70.9 inches) and length of 4635 mm (182.5 inches), it fits well within these limits. Keep in mind to consider mirror width (2043 mm/80.4 inches) when opening doors and maneuvering inside the garage.

The dimensions are closely aligned, with slight variations in width and height reflecting a more modern design and improved interior space utilization.

In terms of size, the Infiniti QX50 I sits comfortably in the compact luxury SUV segment alongside competitors such as the BMW X3, Audi Q5, and Mercedes-Benz GLC. Its length of 4635 mm (182.5 inches), width of 1800 mm (70.9 inches), and height of 1600 mm (63.0 inches) are generally comparable to these rivals, although the QX50's slightly narrower width and modest ground clearance may translate to a slightly different driving feel and parking ease compared to some competitors that are a bit wider or taller.

The 18-inch rims paired with 225/55 R18 tires on the Infiniti QX50 I provide a good balance between ride comfort and handling precision. Larger rims with low-profile tires often improve handling, but can reduce comfort on rough roads. The 18-inch rims and corresponding tire size chosen for the QX50 I offer sufficient sidewall height to absorb road imperfections, maintaining a smooth ride while allowing responsive cornering stability typical of a compact luxury SUV.
