2007 BMW 6 Series Convertible (E64, facelift 2007) Dimensions, Size & Specs

The curb weight of the BMW 6 Series Convertible (E64, facelift 2007) ranges from 1740 kg to 1860 kg (3836 to 4101 lbs). The maximum permissible weight spans between 2140 kg and 2260 kg (4717 to 4980 lbs). These variations depend on specific engine options, included equipment, and optional accessories. The convertible’s reinforced body for structural rigidity adds weight compared to its coupe counterparts, while features such as the retractable hardtop mechanism influence both curb and maximum weights.

The BMW 6 Series Convertible offers a luggage capacity ranging between 300 to 450 liters (10.6 to 15.9 cubic feet). When the rear seats are folded down, the space measures approximately 350 liters (12.3 cubic feet). The convertible’s retractable hardtop storage mechanism can slightly reduce available trunk capacity compared to a fixed-roof model. This makes the vehicle practical for weekend trips or daily use while balancing sporty styling and open-air driving enjoyment.

Given its exterior dimensions—4820 mm (189.8 inches) in length, 1855 mm (73 inches) in width, and a height of about 1373 to 1374 mm (54.1 inches)—the BMW 6 Series Convertible typically fits into a standard residential garage. However, the driver should confirm that the garage width accommodates the car’s width with side mirrors open, which extends to nearly 2036 mm (80.1 inches). Most standard single-car garages are around 2.4 to 2.7 meters (94 to 106 inches) wide, so the car fits comfortably if mirrors are folded or the space is slightly larger.

Compared to its predecessor, the pre-facelift E64 generation (produced from 2003 to 2007), the facelifted 2007 model maintains largely similar dimensions with subtle refinements. The length remains close to 4820 mm, while width and height remain consistent to preserve the vehicle's balanced sporty stance. The facelift primarily focused on aesthetic upgrades and technological enhancements rather than drastic dimensional changes, ensuring continuity in comfort and presence without compromising maneuverability or garage compatibility.

The 2007 BMW 6 Series Convertible is competitive dimensionally with other grand touring luxury convertibles such as the Mercedes-Benz SL-Class and Audi A5 Cabriolet. At 4820 mm (189.8 inches) in length and 1855 mm (73 inches) width, it offers a slightly longer and wider footprint than the Audi A5 Cabriolet (which measures about 4645 mm in length) but is comparable to the Mercedes SL-Class dimensions. Its luggage capacity, between 300 to 450 liters, is also on par with competitors, reflecting thoughtful design to balance open-air appeal with everyday usability.

The BMW 6 Series Convertible offered a variety of rim sizes including 7.5J x 17, 8J x 18, 9J x 18, 9J x 19, and 8.5J x 19 inches, accommodating tire sizes from 245/50 R17 up to 275/35 R19. These wheel and tire combinations allowed owners to tailor the vehicle’s handling and ride comfort. Larger wheels typically improve cornering and aesthetic appeal but may reduce ride softness due to lower profile tires. Conversely, smaller rims with higher profile tires provide a cushier ride but a slightly less aggressive handling feel.

The BMW 6 Series Convertible’s body width is 1855 mm (73 inches), but with side mirrors unfolded, the width extends to 2036 mm (80.1 inches). This increase of 181 mm (7.1 inches) could influence parking and driving in tight spaces, requiring caution in narrow lanes or compact garages. Folding the mirrors to the narrower width helps navigate confined areas more easily and prevents accidental mirror damage, making everyday driving ergonomics more manageable despite the car’s broad stance.

Standing at approximately 1373 to 1374 mm (54.1 inches) tall, the BMW 6 Series Convertible is relatively low-slung compared to typical BMW sedans like the 5 Series which tends to be taller. This reduced height enhances the car’s aerodynamics, center of gravity, and sporty character, improving handling responsiveness and stability, especially in spirited driving scenarios. The low profile also contributes to its sleek design and driver engagement but may require some drivers to adapt when entering or exiting due to the reduced cabin height.

The 2007 facelift of the BMW 6 Series Convertible brought subtle but meaningful upgrades. Primarily, the exterior styling was refreshed with revised front and rear bumpers, updated headlights and taillights featuring improved lighting technology, and enhanced grille designs to keep the model contemporary. Technological improvements included upgrades to onboard electronics, infotainment, and available safety features. Performance remained consistent with minor tuning optimizations for better efficiency and comfort. Overall, the facelift balanced aesthetic modernization with refined driving experience without altering the fundamental chassis or size.
