2005 Buick LaCrosse I Dimensions, Size & Specs

The Buick LaCrosse I has a curb weight ranging from 1585 kg to 1620 kg (3500 to 3570 lbs). This moderate weight lends the sedan a solid, stable feel on the road that enhances handling and safety. However, while heavier than some compact sedans, its weight is typical for mid-size sedans of its class and era, striking a balance between comfort and efficiency. The weight also slightly influences fuel consumption, with the LaCrosse delivering moderate fuel economy best suited for drivers prioritizing comfort and smooth touring over ultra-light efficiency.

The 2005 Buick LaCrosse I offers a trunk capacity of 455 liters (about 16.1 cubic feet). This generous luggage space is practical for everyday use, comfortably handling groceries, luggage for weekend trips, and other cargo. It ranks well compared to many mid-size sedans, giving drivers and families ample room for storage without compromising cabin space. This capacity also supports flexible cargo management when combined with the rear seats, enhancing the LaCrosse I’s appeal as a versatile family sedan.

With its length of 5030 mm (198 inches), width of 1855 mm (73 inches), and height of 1460 mm (57.5 inches), the Buick LaCrosse I typically fits comfortably within a standard residential garage, which usually measures around 6 meters (20 feet) deep and 3 meters (10 feet) wide. The LaCrosse’s width leaves space for opening doors and maneuvering, while its height easily clears garage door openings. However, tight garages or those with additional storage may require careful positioning when parking this vehicle.

The Buick LaCrosse I comes with 6.5J x 17 and 6.5J x 16 rims, paired with tire sizes 225/55 R17 and 225/60 R16, respectively. The 17-inch wheels offer a sportier stance and slightly improved handling due to a lower sidewall tire profile, which better supports cornering. The 16-inch wheels with higher-profile tires provide a softer ride, absorbing road irregularities more comfortably. These options allow buyers to choose between a firmer, more responsive driving feel or enhanced ride comfort, depending on their preferences.

Compared to its predecessor, the Buick Century/GNX-based LaCrosse (which was discontinued in 1999 before the 2005 LaCrosse I was introduced), the 2005 LaCrosse I represents a significant size increase. The length of 5030 mm, width of 1855 mm, and higher curb weight reflect a shift towards a more upscale mid-size sedan with greater interior volume and luggage capacity. This growth allowed Buick to compete more directly with larger entry luxury vehicles, enhancing passenger comfort and presence on the road while moving away from the smaller, lighter models of the late 1990s.

In comparison to other mid-size sedans from the early 2000s, such as the Toyota Camry, Honda Accord, and Ford Taurus, the Buick LaCrosse I is on the larger side. Its 5030 mm length and 1855 mm width exceed many competitors slightly, giving it a roomier interior and a more commanding road presence. The luggage space of 455 liters is also competitive, providing generous cargo capability. Buick’s focus was on comfort and spaciousness, setting the LaCrosse apart as a premium offering in the mid-size sedan segment.

Leveraging its substantial exterior dimensions, the Buick LaCrosse I offers a spacious interior conducive to passenger comfort for front and rear occupants. The wider body enhances shoulder and hip room, while the sedan’s length facilitates generous legroom. The comfortable cabin design benefits families and long-distance travelers, providing an environment that supports both daily commuting and extended drives with minimal fatigue. Additionally, ample trunk space complements the interior volume for a versatile daily-driving sedan.

The Buick LaCrosse I’s chassis and suspension were engineered to support its relatively large size and curb weight, focusing on a smooth ride and confident handling. Features such as a front MacPherson strut suspension and a rear independent multi-link setup contribute to stable road manners and reduced body roll. The suspension tuning balances comfort and control, accounting for the car’s 1585 to 1620 kg (3500 to 3570 lbs) weight, ensuring that the vehicle remains composed under varied driving conditions. This engineering complements the LaCrosse’s design goal of combining luxury sedan comfort with reliable dynamics.

Potential buyers should consider that the Buick LaCrosse I’s relatively large dimensions require sufficient parking space, especially in urban environments where tight parking is common. Though it fits within a standard garage, maneuvering in narrow spaces might need careful attention. The size supports excellent passenger comfort and cargo capacity, ideal for families or those prioritizing interior room. Fuel consumption may be higher than smaller cars due to weight and size, so buyers focused on efficiency should weigh these factors. Overall, the LaCrosse I suits drivers wanting an upscale, spacious sedan with a commanding presence.
