2007 GMC Acadia I Dimensions, Size & Specs

The GMC Acadia I has a width ranging from 1986 mm to 2004 mm, equivalent to about 78.2 to 78.9 inches (around 6.5 feet). This width gives the Acadia a substantial road presence, enhancing stability and providing sufficient shoulder room inside the cabin. While this generous width improves passenger comfort, drivers should note it may require attention when navigating tight city streets or narrow parking spaces.

The height of the GMC Acadia I varies from 1775 mm to 1846 mm, which is approximately 69.9 to 72.6 inches (5.8 to 6.05 feet). This moderate height is typical for midsize SUVs, balancing headroom and aerodynamic profile. Importantly, this height means the Acadia I will fit comfortably in a standard residential garage, which typically has clearance over 2 meters (6.5 feet), leaving adequate space for roof accessories like antennae or roof rails.

The curb weight of the GMC Acadia I ranges between 2112 kg and 2235 kg (4657 to 4927 pounds). This relatively heavy mass is common for midsize SUVs equipped with substantial safety and comfort features. While the weight contributes to a stable and secure driving experience, it also means fuel efficiency might be lower compared to lighter vehicles. Suspension tuning and engine power are calibrated to handle this weight, achieving a smooth and controlled ride.

The GMC Acadia I provides between 558 and 683 liters (19.7 to 24.1 cubic feet) of luggage capacity with all seats in use, which offers practical space for groceries, sports equipment, or travel bags. When the rear seats are folded down, this capacity expands dramatically to between 3282 and 3310 liters (115.9 to 116.8 cubic feet), enabling large cargo loads such as furniture or camping gear. This versatile cargo space makes the Acadia an excellent choice for families and active lifestyles requiring flexible storage.

The ground clearance of the GMC Acadia I is between 189 mm and 193 mm, or roughly 7.4 to 7.6 inches. This moderate ride height allows the vehicle to comfortably clear common obstacles such as speed bumps and rough road surfaces, making it suitable for light off-road adventures or snowy conditions. However, while adequate for a midsize SUV, it is not intended for serious off-roading, so drivers should exercise caution on more rugged terrains.

Yes, the GMC Acadia I generally fits into a standard garage. Typical garages are designed to accommodate vehicles up to around 2.4 meters (7.9 feet) wide and about 2 meters (6.5 feet) tall. With the Acadia I measuring approximately 1.98 to 2 meters wide and 1.78 to 1.85 meters tall, it fits within these common garage limits. However, owners should consider additional exterior attachments like roof racks or large side mirrors which may affect clearance.

The GMC Acadia I marked GMC's entry into a midsize SUV market segment that was less represented by the brand previously. Compared to predecessors like the smaller GMC Envoy or earlier models, the Acadia I is larger, offering more passenger space and cargo capacity. Against similar midsize SUVs such as the Chevrolet Traverse or Ford Explorer of the same period, the Acadia is competitive in overall size, featuring a longer length and greater interior volume, positioning it well for families needing versatile space without stepping into full-size SUV territory.

The GMC Acadia I comes equipped with several tire and rim size options ranging from 7.5J x 18-inch rims up to 8J x 19-inch rims. Tire sizes include 255/65 R18 and 255/60 R19. Larger rims and lower profile tires generally provide better handling and a sportier feel but may reduce ride comfort due to stiffer sidewalls. The 18-inch tires with higher sidewall offer a smoother ride, which many SUV buyers prefer for comfort during daily driving and longer trips.

Introduced in 2007, the GMC Acadia I brought several key features to the midsize SUV segment over its production run until 2013. It offered flexible seating configurations including up to seven-passenger capacity, advanced safety features like stability control and multiple airbags, and modern infotainment options for its time. During these years, it also incorporated improvements such as engine updates and optional all-wheel drive. The Acadia I was praised for comfort, spaciousness, and utility, making it a popular family SUV that balanced capability with everyday usability.
