This weight reflects a solid yet manageable construction designed to provide a stable driving experience while accommodating the safety features and comfort technologies expected in a modern SUV. The weight range indicates the presence of different configurations and equipment packages, balancing performance and fuel efficiency. Despite being a relatively heavy vehicle, the Acadia III’s powertrain and suspension are optimized to handle this mass efficiently.

The 2024 GMC Acadia III offers versatile cargo space to suit various needs. With all rear seats in place, it provides 651 liters (about 23 cubic feet) of luggage capacity, which is adequate for everyday shopping trips, small luggage, or sports equipment. When the rear seats are folded down, the cargo capacity expands significantly to 2761 liters (approximately 97.5 cubic feet), allowing for the transportation of larger items such as furniture, bicycles, or extensive camping gear. This flexibility makes the Acadia III suitable for both daily urban use as well as adventurous outings requiring substantial storage space.

The ride height or ground clearance of the 2024 GMC Acadia III is 172 mm (6.8 inches). This clearance is well-balanced for a mid-size SUV, enabling the vehicle to traverse moderate off-road terrains, such as uneven paths, shallow ditch crossings, and mild obstacles. At the same time, it remains practical for urban scenarios by allowing easy entry and exit for passengers. While not an extreme off-roader, the Acadia III’s ground clearance provides enough flexibility for occasional outdoor excursions without sacrificing everyday drivability and comfort on paved roads.

The 2024 GMC Acadia III offers a variety of tire and rim sizes to cater to different driving preferences and vehicle trims.

Smaller 18-inch rims with higher-profile tires generally provide a smoother ride by absorbing road imperfections better, making them ideal for comfort-focused trims. Larger rims, like 20 and 22 inches with lower-profile tires, enhance the vehicle's sporty look and improve handling responsiveness on well-paved roads but may slightly compromise ride comfort over rough surfaces.

The driving dynamics and stability of the 2024 GMC Acadia III are influenced by multiple critical factors linked to its size and construction. The vehicle’s width of 2021 mm (79.5 inches) and curb weight ranging from 2042 to 2130 kg (4504 to 4697 pounds) provide a low center of gravity and a planted road feel, improving stability during cornering and at highway speeds.
