The 2021 Chevrolet Suburban offers a substantial luggage capacity to meet diverse carrying needs. With the rear seats up, it provides 1164 liters (41.1 cubic feet) of cargo space, suitable for daily essentials and moderate loads.

The 2021 Chevrolet Suburban (GMTT1XX) offers a choice of rims to cater to different styling and performance preferences. Available rim sizes include 18-inch, 20-inch, and 22-inch options. Corresponding tire sizes are 265/65 R18, 275/60 R20, 275/50 R22, and 275/55 R20.

While the specific curb weight is not provided, the Chevrolet Suburban in its current generation typically ranges between approximately 2,630 kg to 2,750 kg (5,800 to 6,060 lbs), depending on configuration and trim. This weight reflects the Suburban's large size, body-on-frame construction, and robust features designed for durability, towing, and passenger comfort.

Given its size — 5732 mm (225.6 inches) in length, 2059 mm (81.1 inches) in width without mirrors, and 1923 mm (75.7 inches) in height — the Chevrolet Suburban is quite large and may not fit comfortably in many standard residential garages. Typical US garage sizes are around 6.1 meters (20 feet) deep and 3 meters (10 feet) wide. Therefore, while width might fit, the Suburban’s length and height could be restrictive, necessitating a larger or custom garage space.

Compared to the previous generation, the 2021 Chevrolet Suburban (GMTT1XX) is slightly larger in overall dimensions, emphasizing increased interior space and cargo capacity. The newer model grew in length to 5732 mm (225.6 inches) and widened to 2059 mm (81.1 inches), providing improved legroom and luggage capacity by extending its platforms. This evolution reflects Chevrolet’s commitment to enhancing passenger comfort and utility in the full-size SUV market.

The 2021 Chevrolet Suburban (GMTT1XX) is among the longest and widest in the full-size SUV segment, rivaling vehicles like the Ford Expedition Max and GMC Yukon XL. Its length of 5732 mm (225.6 inches) often exceeds many competitors, offering superior passenger and cargo space. Its width of 2059 mm (81.1 inches) supports a commanding road presence, while its height of 1923 mm (75.7 inches) is typical for this SUV class, balancing headroom and aerodynamics.

Due to its large size, the Chevrolet Suburban requires extra caution when parking and maneuvering, especially in tight urban environments. Its length of 5732 mm (225.6 inches) can make navigating narrow streets and parking lots challenging. However, the Suburban often includes features like rearview cameras, parking sensors, and driver-assist technologies to alleviate these challenges and improve situational awareness.

The 2021 Chevrolet Suburban is engineered to maximize passenger comfort across three rows of seating. With its extended length and width, it offers generous legroom and headroom for all passengers, including those in the third row. This spaciousness is ideal for families or groups requiring comfortable long-distance travel. The design focus on interior space contributes to an overall feeling of openness and luxury within the cabin.

The 2021 Chevrolet Suburban improves on its predecessors by offering more space, enhanced technology, and modernized styling while maintaining its reputation for ruggedness and versatility. It provides improved cargo capacity with 1164 liters (41.1 cubic feet) of space behind the last row and up to 4097 liters (144.7 cubic feet) with folding seats, which is higher than many rivals. Advanced safety features, updated infotainment systems, and multiple powertrain options further distinguish this generation, making it a leader in full-size SUVs.
