The maximum allowable weight (gross vehicle weight) ranges between 2085 kg (4598 lbs) and 2255 kg (4970 lbs).

The BMW 6 Series Convertible (E64) offers 300 liters (10.6 cubic feet) of luggage space with the rear seats up, which is quite reasonable for a convertible. When the rear seats are folded down, the luggage capacity increases slightly to 350 liters (12.4 cubic feet). This increase provides additional room for larger items while maintaining the practicality expected from a grand touring convertible.

Yes, the BMW 6 Series Convertible (E64) generally fits comfortably into a standard residential garage. With a width of 1855 mm (73 inches or about 1.85 meters), it is well within the typical 2.4-meter (7.9 feet) garage width. Its length of 4820 mm (189.8 inches or roughly 4.8 meters) also fits comfortably under the standard garage length of 5 meters (16.4 feet). However, caution should be taken while parking due to the car’s wide stance and long length to avoid any tight maneuvers.

The predecessor to the E64 convertible was the BMW 6 Series E24 coupe, which did not have an official convertible version. The E64 represented BMW’s first dedicated convertible in the 6 Series range, thus marking an increase in dimensions compared to any two-door variants that preceded it. The E64 is notably larger, longer, and wider, reflecting advancements in safety, luxury, and structural rigidity for convertible design during 2003-2007. This generation brought a more modern, spacious, and refined driving experience compared to earlier 6 Series coupes.

Compared to rivals like the Mercedes-Benz SL-Class (R230) or the Audi A5 Cabriolet (first generation starting 2007), it is similar in length and width, though the E64 typically offers a slightly lower height. Its luggage capacity is average for the class, balancing sporty proportions with practicality. The E64’s curb weight is on par or slightly heavier due to its robust build and luxurious features, placing it firmly among premium grand tourers rather than pure sports cars.

The BMW 6 Series Convertible (E64) came with tire and rim options primarily in two sizes. The rims were sized 17 to 18 inches in diameter, with rim specifications of 7.5J x 17 or 8J x 18. Tire sizes were 245/40 R17 for the 17-inch wheels, and 245/45 R18 for the 18-inch wheels. These tire sizes and rim specifications contribute to the vehicle's sporty handling dynamics and aesthetic stance.

With a length of 4820 mm (189.8 inches), a width of 1855 mm (73 inches), and a low height of 1373 mm (54 inches), the BMW 6 Series Convertible (E64) benefits from a low center of gravity and wide track, giving it stable cornering and confident handling. The sizeable footprint also provides a commanding road presence, typical of a luxury grand tourer convertible, which balances elegance with sportiness. Although its size might make tight city maneuvering more challenging, the car performs exceptionally well on highways and winding roads.

The curb weight of the BMW 6 Series Convertible (E64) ranges from 1685 kg (3715 lbs) to 1855 kg (4088 lbs), with a maximum allowable weight from 2085 kg (4598 lbs) to 2255 kg (4970 lbs). This weight reflects its solid build quality, luxury features, and structural reinforcements typical for convertibles. While the weight contributes to a stable and comfortable ride with good handling characteristics, it can slightly reduce fuel efficiency compared to lighter sport convertibles. However, engine options in this class are designed to balance strong performance with reasonable fuel consumption.

The BMW 6 Series Convertible (E64) features a 2+2 seating arrangement, meaning it has two front seats and two smaller rear seats. The rear seats are best suited for short trips or smaller passengers due to limited legroom caused by the coupe-style roofline and convertible mechanism. While the rear bench can fold down to increase luggage capacity, it compromises passenger space. Overall, the cabin is designed to focus on driver and front passenger comfort, with rear seats providing flexibility rather than full-time usability.
