2003 GMC Envoy II XL (GMT370) Dimensions, Size & Specs

The curb weight of the 2003-2006 GMC Envoy II XL ranges between 2165 kg to 2393 kg (4776 to 5275 pounds), varying based on trim level and optional equipment. The maximum allowed weight, or Gross Vehicle Weight Rating (GVWR), ranges from 2812 kg to 2903 kg (6200 to 6400 pounds). This weight capacity ensures the vehicle can carry passengers, cargo, and tow moderately heavy loads safely while maintaining performance and durability. The weight balances a rugged SUV structure with overall manageable mass for driving dynamics and fuel efficiency relative to its size.

The GMC Envoy II XL (2003-2006) offers a versatile cargo area, with a luggage capacity ranging from 594 to 631 liters (approximately 21 to 22.3 cubic feet) when the rear seats are upright, suitable for everyday groceries, luggage, or equipment. When the rear seats are folded down, the cargo space expands considerably to between 2839 and 3041 liters (about 100 to 107.4 cubic feet), providing ample room for large items, camping gear, or bulky cargo. This flexibility is a key advantage of the Envoy II XL, catering to both passenger comfort and the need for significant storage space.

The GMC Envoy II XL has a ground clearance of 203 mm (8 inches), which is quite adequate for an SUV designed for both urban and light off-road driving. This clearance allows the vehicle to navigate over rough terrain, rocks, and uneven surfaces without damaging the undercarriage. It also contributes to the SUV's ability to handle snow, mud, and water crossings reasonably well compared to lower vehicles. The decent ride height improves driver visibility and adds to the vehicle's rugged and versatile character, positioning it well within the mid-size SUV segment for moderate off-road use.

The GMC Envoy II XL comes equipped with rim sizes of 7.0J x 17 inches and 8.0J x 18 inches, offering a range of options for style and performance. Corresponding tire sizes include 245/65 R17 and 245/60 R18, respectively. The 17-inch rim and higher profile tires provide a balanced ride quality with better cushioning over bumps, while the 18-inch rim option offers a sportier look and potentially sharper handling at the cost of a firmer ride. These tire sizes also facilitate good road grip and off-road capability thanks to the SUV's design priorities.

Most standard residential garages typically have a door width of around 2400 mm to 2700 mm (7.9 to 8.9 feet), a door height of about 2030 mm (6.7 feet), and interior depth of roughly 5400 mm (17.7 feet). Given the Envoy II XL's width of 1897 mm (74.7 inches or about 6.2 feet), it comfortably fits through a standard garage door width. However, its height of 1917 mm (75.4 inches or approximately 6.3 feet) approaches the typical garage door height and may be a tight fit if the garage ceiling is low or if light fixtures hang down. Lengthwise, at 5271 mm (207.5 inches or about 17.2 feet), it also fits within the general garage depth but leaves limited extra space. Therefore, while the Envoy II XL can fit most standard garages, owners should measure their specific garage dimensions to ensure adequate clearance.

The Envoy II XL (GMT370) introduced in 2003 is a lengthened and wider version compared to its predecessor, providing increased interior space and cargo capacity. Specifically, this model features a significant length of 5271 mm (207.5 inches), which is notably longer than the first-generation Envoy’s approximate length around 4877 mm (192 inches). This increase grants the XL variant more passenger legroom and expanded cargo space, addressing consumer demand for a more versatile mid-size SUV. Width and height also saw slight increments, contributing to better road presence and cabin comfort. Overall, the Envoy II XL represents a clear size upscaling aiming to compete better with full-size SUVs while maintaining manageable maneuverability relative to the original model.

The 2003-2006 GMC Envoy II XL, with its length of 5271 mm (207.5 inches), width of 1897 mm (74.7 inches), and height of 1917 mm (75.4 inches), competes well in the mid-size SUV segment. It is larger than many rivals such as the Toyota 4Runner and Ford Explorer of the same era, which typically measured around 4800-5000 mm in length. Its cargo capacity with rear seats folded (up to 3041 liters or 107.4 cubic feet) surpasses many competitors, making it particularly strong in hauling capability. Weight-wise, it is heavier than many competitors, which may affect fuel economy but contributes to a solid, sturdy feel on the road. Its 203 mm (8 inch) ground clearance also provides adequate off-road potential compared to peers. Overall, the Envoy II XL offers a compelling balance of size, space, and ruggedness among mid-size SUVs of its time.

Due to its larger size and heavier curb weight ranging from 2165 to 2393 kg (4776 to 5275 lbs), the GMC Envoy II XL naturally faces challenges in fuel efficiency compared to smaller, lighter SUVs. The added length and width increase aerodynamic drag, while the weight affects acceleration and braking performance. Generally, this translates into moderate fuel economy figures typical for SUVs of this class and era, with fuel consumption tending to be higher than smaller crossover vehicles. However, the increased mass contributes positively to ride stability and a more planted feel on highways, enhancing driving confidence. The size and weight both support the vehicle's utility and passenger comfort but require compromises in fuel usage and maneuverability.

The 2003-2006 GMC Envoy II XL offered a range of engine options tailored for power and utility. Most commonly, it featured a 4.2-liter inline six-cylinder engine producing around 270 horsepower, providing solid performance for daily driving and moderate towing. Additionally, a more robust 5.3-liter V8 engine option delivering approximately 290-300 horsepower was available for buyers seeking enhanced towing capacity, acceleration, and overall capability. These engines were typically mated to a four-speed automatic transmission, supporting smooth gear changes and efficient power delivery. The V8 option, combined with the vehicle's substantial weight and size, made the Envoy XL an effective SUV for hauling gear, family trips, or light off-roading, while the inline-six offered a balance between performance and efficiency.
