The maximum permissible weight ranges from 1940 kg to 2095 kg (4277 to 4619 lbs). This spread reflects different engine configurations and equipment levels. The relatively high curb weight for a coupe reflects the car's extensive luxury features, solid build quality, and structural reinforcements aimed at safety and driving dynamics.

The BMW 6 Series (E63) coupe provides a luggage capacity of 450 liters (15.9 cubic feet). For a coupe of its category, this capacity is quite generous, allowing for suitable storage space for weekend trips or daily use. The trunk is well shaped for accommodating suitcases and bags, and the rear seats can be folded down to increase cargo capacity when needed, enhancing its practicality despite its sporty coupe design.

Yes, the BMW 6 Series (E63) coupe generally fits into a standard residential garage. With a width of 1855 mm (73 inches) and a height of 1373 mm (54 inches), it is within typical garage size limits. Standard garages in many regions are designed to accommodate vehicles up to about 2.4 meters wide (including mirrors) and 2 meters in height, so the E63 fits comfortably with adequate clearance for opening doors and moving around. However, owners should measure their individual garage space if it is particularly narrow or has storage elements that reduce accessible width.

The BMW 6 Series (E63) coupe's width of 1855 mm (73 inches) and height of 1373 mm (54 inches) place it comfortably in the mid-to-large segment among luxury coupes from the early 2000s. Competitors like the Mercedes-Benz CL-Class and Audi A5 also ranged closely in width and height. Its width contributes to a stable road stance and sporty handling, while the relatively low height maintains an aerodynamic and aggressive coupe silhouette. This size balance was typical for grand tourers aiming to blend performance with luxury and comfort.

The BMW 6 Series (E63) typically comes with rim sizes between 17 and 18 inches, fitted with tires sized 245/40 R17 or 245/45 R18. Larger rims with low-profile tires contribute to sharper, more responsive handling and enhanced road grip, which suit the sporty character of the coupe. However, low-profile tires can also transmit more road imperfections to the cabin, so the suspension tuning balances sportiness and ride comfort. Overall, these rim and tire specifications support the E63's role as a luxurious grand tourer with dynamic driving abilities.

The BMW 6 Series (E63) introduced in 2003 measures 4820 mm (189.8 inches) in length, which represented a slight increase compared to its predecessor, the E24 6 Series, produced until 1989. The earlier E24 was about 4715 mm (185.6 inches) long, so the increase in length reflects BMW's effort to provide more interior comfort, updated styling, and enhanced safety equipment. The additional length also improved presence on the road and allowed integration of modern technologies while maintaining the coupe's stylish proportions.

Compared with luxury coupes like the Mercedes-Benz CL-Class (C215) or Lexus SC430 from the early 2000s, the BMW 6 Series (E63) is slightly longer or similar in length but tends to be narrower than the CL-Class. For example, the CL-Class measures around 4990 mm (196.5 inches) long and 1880 mm (74 inches) wide. The E63’s 1855 mm width and 4820 mm length strike a balance that offers good road presence without being overly large for urban use. Additionally, the E63’s relatively low height of 1373 mm (54 inches) enhances its sporty coupe stance compared to some taller rivals.

The BMW 6 Series (E63) coupe weighs between 1490 kg and 1695 kg (3285 to 3735 lbs) curb weight depending on engine and equipment variants. Heavier trims generally feature larger engines and more luxury or safety equipment. This weight is moderate for a luxury grand tourer and influences both performance and fuel efficiency. The car’s weight contributes to a stable and planted feel on the road, enhancing driving dynamics and comfort. However, increased weight can reduce acceleration times and fuel economy compared to lighter rivals, so effective engine tuning and transmission choices are crucial for balancing performance and efficiency.
