2000 Chevrolet Suburban (GMT800) Dimensions, Size & Specs

The curb weight of the Chevrolet Suburban (GMT800) ranges from 2310 kg to 2740 kg (5,093 to 6,038 lbs), which corresponds to the vehicle's weight without passengers or cargo but includes standard equipment and fluids. Depending on configuration and options, the maximum weight—often called gross vehicle weight rating (GVWR)—varies from 3175 kg to 3900 kg (7,000 to 8,598 lbs). This maximum weight accounts for passengers, cargo, and trailer tongue weight, reflecting the Suburban's ability to carry heavy loads and tow substantial trailers, a hallmark of its full-size SUV class.

With rear seats in place, the Chevrolet Suburban (GMT800) offers a generous luggage capacity of approximately 1290 to 1294 liters (about 45.5 to 45.7 cubic feet), which provides ample room for groceries, luggage, or everyday cargo. When the rear seats are folded down, transforming the interior into a large cargo space, the luggage capacity dramatically increases to between 3720 and 3726 liters (131.4 to 131.7 cubic feet). This expansive volume highlights the Suburban's versatility, making it highly suitable for transporting bulky items, large groups of luggage, or outdoor equipment on extended trips.

Fitting a Chevrolet Suburban (GMT800) into a standard household garage can be challenging due to its size. The length of 5570 mm (219.3 inches or roughly 18.3 feet) and a width reaching up to 2027 mm (79.7 inches or 6.6 feet) means it occupies more space than average vehicles. Additionally, its height varies between 1861 mm and 1958 mm (73.3 to 77.1 inches or about 6.1 to 6.4 feet), which is generally acceptable for most garage door heights but may cause issues if overhead clearance is limited. Overall, owners should measure their garage size carefully, considering both length and width availability. Standard single-car garages might be tight or insufficient, so larger or custom garages are often better suited for this full-size SUV.

The Chevrolet Suburban (GMT800) utilizes tire sizes 265/70 R17 and 245/75 R16, which are typical for SUVs requiring a balance of off-road capability, on-road comfort, and load-carrying capacity. The wider 265 mm tire width on the 17-inch rims offers enhanced grip and stability, particularly helpful given the vehicle's substantial size and weight, improving handling and cornering. The 70 and 75 aspect ratios indicate relatively tall sidewalls, which contribute to ride comfort by absorbing road imperfections. Meanwhile, the 16-inch tires with slightly narrower width provide a smooth ride but may have less cornering precision compared to the wider 17-inch alternatives. The fitment choice often depends on owner preference for comfort versus performance and local road conditions.

The height of the Chevrolet Suburban (GMT800) ranges from 1861 mm to 1958 mm (73.3 to 77.1 inches), depending on factors such as roof configurations (including the availability of roof racks or optional equipment) and suspension variations. A taller height improves ground clearance and off-road capability, making it easier to traverse rough terrain and off-road obstacles. However, increased height can also impact vehicle aerodynamics and may slightly affect fuel economy. Additionally, higher roof variants provide more headroom inside, enhancing passenger comfort for taller occupants. This range allows the Suburban to balance between urban usability and rugged utility, accommodating different driver needs from family transport to adventurous trips.

Compared to its predecessor, the GMT400 generation Chevrolet Suburban (produced until 1999), the GMT800 Suburban introduced in 2000 is generally larger and more robust. The length of the GMT800 is approximately 5570 mm (219.3 inches), which is slightly longer than the prior generation, providing increased interior space and cargo capacity. Width and height have also seen modest increases to enhance passenger comfort and road presence. These size enhancements improve the Suburban's capability as a family and utility vehicle, offering more room for passengers and gear. The increased dimensions also reflect the shift towards more luxury and advanced safety features during the GMT800 production years, representing a significant evolution over the GMT400 generation.

When compared to other full-size SUVs of the early 2000s such as the Ford Excursion, GMC Yukon XL (its corporate cousin), and the Dodge Durango, the Chevrolet Suburban (GMT800) stands out for its balanced size and functional design. Its length of 5570 mm (219.3 inches) is substantial but slightly shorter than the Ford Excursion, which was known as one of the largest SUVs at the time. The width and height put it on par or slightly larger than competitors like the Dodge Durango but similar to the GMC Yukon XL. The Suburban's boxy yet purposeful design maximizes interior cargo and passenger space. Its versatility, towing capacity, and rugged build made it a favorite among consumers needing a reliable, full-size SUV with strong size and space credentials.

The Chevrolet Suburban (GMT800) offers impressive cargo space, making it highly versatile for carrying different types of loads. With the rear seats upright, the vehicle provides around 1290 to 1294 liters (45.5 to 45.7 cubic feet) of luggage capacity, suitable for everyday hauling needs like groceries or sports equipment. Folding the rear seats down dramatically expands the cargo area to between 3720 and 3726 liters (131.4 to 131.7 cubic feet), enabling the transport of large items such as furniture or multiple suitcases for extended trips. This flat-folding seat design enhances usability, allowing owners to switch between maximum passenger seating and maximum cargo volume quickly, a key feature for families or professionals who require both passenger comfort and utility.

Given its large dimensions and weight range of 2310 to 2740 kg (5,093 to 6,038 lbs) curb weight, and a maximum weight capacity of up to 3900 kg (8,598 lbs), the Chevrolet Suburban (GMT800) is suitable for heavy-duty tasks such as towing boats, trailers, or campers, making it popular among outdoor enthusiasts and large families. Its spacious interior and roomy cargo area support family trips and daily commuting with comfort. Additionally, the vehicle's strong construction supports commercial use cases including transporting equipment or shuttle services. Despite its size, the Suburban is designed to provide a balance between rugged capability and passenger comfort — making it a versatile SUV choice for a variety of demanding driving conditions.
