2008 Maserati Quattroporte Sport GT S Dimensions, Size & Specs

The Quattroporte Sport GT S has a curb weight of 1990 kg (4387 lbs) and a maximum permissible weight of 2365 kg (5215 lbs). The substantial curb weight reflects the car's robust construction and luxury furnishing, which include advanced safety and comfort features. Despite the weight, Maserati's engineering ensures agile performance, aided by a powerful engine and well-tuned suspension to balance comfort and sporty dynamics. The maximum weight is important for understanding load capacity, with the car designed to maintain performance levels even when fully loaded with passengers and luggage.

This Maserati offers a luggage capacity of 450 liters (approximately 15.9 cubic feet), which is quite generous for a luxury sports sedan. This capacity allows for ample storage for travel and daily use without compromising passenger space. Compared to typical executive sedans, which often have luggage spaces in the 400-500 liter range, the Quattroporte Sport GT S balances its sporty design with practical utility, making it suitable for long trips needing more than just a minimal amount of cargo space.

With its length of 5097 mm (200.7 inches), width of 1885 mm (74.2 inches), and height of 1423 mm (56 inches), the Quattroporte Sport GT S fits comfortably in most standard residential garages, which typically accommodate cars up to about 6 meters (19.7 feet) long and around 2.4 meters (7.9 feet) wide. However, garage owners should ensure sufficient space for opening doors and moving around the vehicle, particularly because the car's width is on the wider side for a sedan. In summary, it fits into a standard garage but with limited extra room to spare.

Compared to the previous generation Quattroporte (M139, produced until 2007), the Sport GT S is slightly larger, particularly in length and width. The M139 measured approximately 5100 mm in length, quite similar, but the Sport GT S offers subtle refinements that translate into a sportier and more aggressive stance through a wider body and lower height. These changes improve aerodynamic efficiency and interior space usability. This evolution showcases Maserati's efforts to blend luxury with enhanced driving dynamics by growing in physical dimensions while maintaining the hallmark style and performance.

The substantial exterior dimensions of the Quattroporte Sport GT S translate into a roomy and comfortable interior, well-suited for a full-size luxury sedan. The generous length and width provide ample legroom and shoulder room for both front and rear passengers. Height of 1423 mm (56 inches) allows for a comfortable headspace without making the car feel bulky. Maserati’s emphasis on craftsmanship and ergonomics ensures that the cabin delivers both luxury and a sporty feel, with seats designed to support spirited driving while also contributing to passenger comfort.

At 1885 mm (74.2 inches) wide, the Quattroporte Sport GT S is broader than many sedans, which provides enhanced road stability and cornering grip, contributing to sporty handling. However, this increased width can pose challenges on narrow or congested city streets and tight parking spaces. Drivers should be cautious of curb clearance and adjacent vehicles, especially in older urban areas. The width is a trade-off for improved performance and presence but means the driver should be mindful in environments requiring precise vehicle placement.

When compared to competitors like the BMW M5, Audi S8, and Mercedes-Benz E63 AMG of the same era, the Quattroporte Sport GT S stands out with its larger length at 5097 mm (200.7 inches) and relatively broad width of 1885 mm (74.2 inches). While many rivals have similar heights, Maserati's slightly lower profile emphasizes its sporty character. Luggage capacity and curb weight are also competitive, situating the Quattroporte as a blend of Italian style, luxury, and dynamic capability alongside German engineering benchmarks, appealing to buyers seeking exclusivity and performance in a larger sedan package.

The larger size and higher weight (1990 kg or 4387 lbs curb weight) of the Sport GT S generally result in a higher fuel consumption compared to smaller luxury sedans, particularly in urban environments. While the increased frontal area from its width and length adds aerodynamic drag at higher speeds, Maserati’s engineering focuses on balancing performance with reasonable efficiency given the car's sporty V8 or V6 powertrains. Urban usability can be slightly compromised due to its footprint, making maneuvering and parking more challenging than smaller vehicles, but technological aids like parking sensors help mitigate these issues.

With a height of 1423 mm (56 inches), the Quattroporte Sport GT S is relatively low for a sedan, which benefits driving dynamics by lowering the car's center of gravity. This contributes to improved handling, reduced body roll, and enhanced stability at high speeds or during spirited driving. For passengers, the lower height means a sportier cabin feeling, but Maserati has carefully designed seat positions and cabin ergonomics to maintain headroom comfort for both front and rear occupants. The balance ensures the sedan delivers both driver excitement and passenger accommodation without compromise.
