2025 Chevrolet Suburban (GMTT1XX, facelift 2024) Dimensions, Size & Specs

The 2025 Chevrolet Suburban (GMTT1XX facelift) has a curb weight ranging between 2576 kg to 2746 kg (5679 to 6055 lbs), depending on configuration and trim. Its maximum allowable weight (gross vehicle weight rating) falls between 3360 kg and 3476 kg (7409 to 7660 lbs). This weight range highlights the vehicle's robust construction and capability to handle heavy passenger and cargo loads. The ample weight capacity supports towing and hauling requirements typical for large SUVs, accommodating both family-oriented and utility needs with relative ease.

Fitting a 2025 Chevrolet Suburban into a standard residential garage can be challenging due to its large size. Standard garage dimensions in many homes are about 2440 mm (8 feet) wide and 4880 mm (16 feet) deep, which can accommodate most mid-sized to large SUVs. However, the Suburban’s length is approximately 5720 mm (225 inches or about 18.75 feet), exceeding the typical garage depth by nearly a meter (3.75 feet). Garage width can also be tight given the vehicle's width around 2050 mm (81 inches or 6.75 feet) when factoring in door mirror clearance. Therefore, without a deeper or wider garage, parking the Suburban fully inside is generally not feasible unless modifications or oversized garages are available.

The 2025 Chevrolet Suburban’s width of around 2050 mm (81 inches) and height close to 1940 mm (76 inches) are typical for a full-size SUV but require careful consideration in parking and tight spaces. The broad width provides spacious cabin room yet means the vehicle will take up significant lateral space in parking lots; wider spots or more caution are advisable when parking next to other vehicles. The height, while beneficial for visibility and interior cargo space, might limit access to parking garages with low clearance heights, typically under 2 meters (6.5 feet). Drivers should assess parking facilities for clearance and width constraints to avoid potential difficulties or damage.

The 2025 Chevrolet Suburban offers rim sizes from 18 to 24 inches, with corresponding tire sizes including 265/65 R18, 275/55 R20, 275/60 R20, 275/50 R22, and 285/40 R24. Larger rims with lower-profile tires, such as 22- and 24-inch options, typically provide a more aggressive look and improved highway handling by reducing sidewall flex. However, they may result in a firmer ride, especially on rough roads, compared to smaller 18 or 20-inch wheels with taller sidewalls which absorb bumps better and improve comfort. The diverse offerings allow customers to prioritize between aesthetics, ride comfort, and performance depending on their driving needs.

The 2025 Chevrolet Suburban is engineered with ample cargo space, making it ideal for large families and heavy hauling requirements. While exact cargo volume figures for the facelift were not specifically provided, the previous generation Suburban offered about 722 liters (25.5 cubic feet) behind the third row, expanding to more than 2820 liters (99.6 cubic feet) with the second and third rows folded. This generous cargo capacity ensures space for luggage, groceries, sports equipment, and more. Additionally, the Suburban's three-row configuration typically seats seven to nine passengers comfortably, further making it a practical option for large group outings or family adventures.

The 2025 Chevrolet Suburban (GMTT1XX facelift) builds upon its predecessor's robust full-size SUV platform. Although the facelift primarily includes updated exterior styling and interior enhancements, dimensional changes are minimal. The curb weight slightly varies between 2576 and 2746 kg compared to previous models, reflecting updates in materials or equipment. Exterior dimensions like length, width, and height remain comparable, continuing its reputation as one of the longest and widest SUVs in production. Thus, the 2025 facelift maintains spatial and size consistency with its direct predecessor while offering contemporary design and technology improvements.

The 2025 Chevrolet Suburban is among the largest SUVs in its segment, competing directly with the Ford Expedition and GMC Yukon. Dimensionally, the Suburban’s length is around 5720 mm (225 inches), making it longer than the Ford Expedition Max at approximately 5630 mm (221.5 inches) and close to the GMC Yukon XL which shares the same platform and similar dimensions. Width and height figures also are comparable; all three SUVs range around 2050 mm (81 inches) wide and 1940 mm (76 inches) tall. While all three vehicles offer three-row seating and substantial cargo space, the Suburban’s length often translates to slightly more cargo room and passenger space, though this comes with the characteristic challenges of maneuvering a very large vehicle.

With curb weights ranging from 2576 to 2746 kg (5679 to 6055 lbs), the 2025 Chevrolet Suburban’s hefty mass affects both fuel efficiency and driving dynamics. Heavier weight generally reduces fuel economy, particularly in city driving and stop-and-go conditions. However, the Suburban’s modern powertrains and advanced aerodynamics help mitigate some of the efficiency loss typical of large SUVs. In terms of driving dynamics, greater weight contributes to a stable and planted feel at highway speeds but can result in slower acceleration and longer braking distances. This robust structure also lends itself well to towing and heavy-duty hauling, making trade-offs between performance, efficiency, and utility essential considerations for buyers.

The 2025 Chevrolet Suburban is primarily designed as a large family SUV with some light off-road capabilities, especially when equipped with optional four-wheel drive and off-road packages. Its considerable size (length around 5720 mm and width 2050 mm) and weight (up to 2746 kg curb weight) mean maneuvering on narrow or rugged trails can be challenging compared to smaller SUVs. Ground clearance and suspension tuning for off-road use are sufficient for dirt roads, gravel paths, and mild trails but the Suburban is not optimized for extreme off-roading like dedicated off-road vehicles. Drivers should consider the vehicle's size in tight off-road conditions, and while it offers robust performance, it's best suited for mixed on-road/off-road use rather than extreme terrain.
