2004 Infiniti QX56 Dimensions, Size & Specs

The curb weight of the Infiniti QX56 from 2004 to 2007 ranges from 2430 kg to 2615 kg (approximately 5357 to 5764 pounds). The maximum permissible weight, which includes passengers, cargo, and fuel, is up to 3175 kg (about 7000 pounds). This relatively high weight reflects its durable construction, robust V8 engine, and solid frame designed to support off-road capability and towing.

The Infiniti QX56 offers a generous luggage capacity of 1733 liters (61.1 cubic feet) with the rear seats folded down. This amount of cargo space is competitive within its full-size SUV class, making it practical for carrying large loads, luggage for long trips, or sports equipment. The versatile interior layout allows passengers to easily increase cargo space, enhancing the vehicle's utility for both everyday needs and recreational use.

The Infiniti QX56 has a ride height or ground clearance of 270 mm (10.6 inches). This relatively high ground clearance is advantageous for an SUV, enabling the vehicle to clear obstacles like rocks, tree roots, and uneven terrain without damaging the undercarriage. It improves off-road capability and confidence when driving on rough or unpaved roads, while still maintaining a smooth on-road ride.

The Infiniti QX56 comes equipped with 18-inch rims sized 8J x 18 and tires sized 265/70 R18. These relatively large and wide tires provide a good balance of comfort, handling, and traction, especially given the SUV’s heavy weight. The tire size supports the vehicle's capability to maintain stability at highway speeds while offering grip for light off-road and wet conditions. Additionally, the 18-inch wheels add to the QX56’s rugged and upscale stance on the road.

With a length of 5250 mm (206.7 inches), width of 2000 mm (78.7 inches), and a height of 1970 mm (77.6 inches), the Infiniti QX56 is quite large compared to typical cars. Most standard garages are approximately 5400 mm (213 inches) deep and 3000 mm (118 inches) wide, so while the SUV will fit in many standard garages, the fit may be tight, especially if the garage is used for storage or contains other vehicles. Careful maneuvering is recommended to avoid potential scrapes or damage.

The Infiniti QX56, introduced in 2004, is significantly larger than the Infiniti QX4, which was a mid-size SUV. While the QX4 had a length of about 4700 mm (185 inches) and was narrower and shorter, the QX56 stretches to 5250 mm (206.7 inches) long and 2000 mm (78.7 inches) wide. This upsize reflects Infiniti's move towards a true full-size luxury SUV, offering more interior space, improved comfort, and increased towing capacity. The QX56 is also taller at 1970 mm (77.6 inches) compared to the QX4, emphasizing its larger footprint and road presence.

When compared to other full-size SUVs from the mid-2000s like the Cadillac Escalade, Lincoln Navigator, and Lexus LX 470, the Infiniti QX56 holds its own in terms of size. The QX56’s length of 5250 mm (206.7 inches) is similar to that of the Escalade and Navigator, making it competitive in passenger and cargo space. Its width of 2000 mm (78.7 inches) and height of 1970 mm (77.6 inches) also align closely with its rivals. Overall, the QX56 offers comparable interior volume, rugged ground clearance of 270 mm (10.6 inches), and a luxurious premium feel built for both urban and off-road versatility.

The Infiniti QX56, produced from 2004 to 2007, is a full-size luxury SUV known for combining power, luxury, and utility. It features a 5.6-liter V8 engine delivering strong performance, advanced safety features for its time, and a high-quality interior that included leather seating and wood trim. The SUV’s design was focused on comfort, ample space for up to eight passengers, and off-road capability thanks to its body-on-frame construction and high ground clearance. The QX56 also boasted features such as a premium audio system, climate control, and optional all-wheel drive.

The 270 mm (10.6 inches) ground clearance of the Infiniti QX56 is a critical dimension for practical off-road and everyday driving use. This height allows the vehicle to traverse uneven surfaces, debris, and shallow water crossings without damaging vital components underneath. It also helps in improving approach and departure angles which is important for any SUV designed to handle rough terrain. Moreover, a high ground clearance contributes to enhanced driver visibility and better handling on poor road conditions, making the QX56 versatile for both urban and adventurous driving scenarios.
