The BMW 3 Series Convertible (E93) has a width of 1782 mm without mirrors, which is approximately 70.2 inches or 5 feet 10.2 inches. When including the opened side mirrors, the width increases to 1985 mm, equivalent to about 78.1 inches or 6 feet 6.1 inches. This wider dimension with mirrors unfolded is critical to consider for parking and maneuvering, especially in narrow spaces, reflecting the car's broader stance for improved stability and road presence.

The height of the BMW 3 Series Convertible (E93) is 1384 mm, which converts to approximately 54.5 inches or 4 feet 6.5 inches. This relatively low profile contributes to the car’s sporty look and enhances aerodynamic performance. Despite being a convertible with a retractable hardtop, the design maintains a sleek height that blends style with lowered center of gravity for better handling.

The curb weight of the BMW 3 Series Convertible (E93) ranges from 1600 kg to 1780 kg. In pounds, this equates to approximately 3527 lbs to 3924 lbs. The variation in curb weight depends on specific trims, engine options, and included equipment. The weight balance is carefully managed to retain agility and performance despite the additional weight from the convertible hardtop mechanism.

The BMW 3 Series Convertible (E93) has a ground clearance ranging from 138 mm to 143 mm. This is approximately 5.4 inches to 5.6 inches. The relatively low ride height is typical for a sporty convertible, optimizing handling and aerodynamic performance but requiring careful navigation over speed bumps and uneven terrain.

The luggage capacity of the BMW 3 Series Convertible (E93) is 210 liters (approximately 7.4 cubic feet) with the rear seats upright. When the rear seats are folded down, the capacity expands to 350 liters, or about 12.4 cubic feet. This expanded space is valuable for transporting larger items, although the convertible design and hardtop mechanism slightly limit the overall cargo space compared to non-convertible models.

Yes, the BMW 3 Series Convertible (E93) generally fits into a standard garage. Standard garage widths vary but typically measure around 2.4 to 2.7 meters (approximately 7.9 to 8.9 feet). While the car's width with mirrors extended is about 1.985 meters (6 feet 6 inches), it’s essential to fold in the mirrors to fit the car comfortably. The length of up to 4.588 meters (15 feet) and height of 1.384 meters (4 feet 6.5 inches) are well within typical garage dimensions, making parking and storage practical in most residential garages.

Compared to its predecessor, the E46 Convertible, the BMW 3 Series Convertible (E93) is slightly larger and heavier. The E46 convertible had a length of about 4,410 mm (173.6 inches), making the E93 about 170 mm (6.7 inches) longer. Width is similar, though the E93’s mirrors extend wider. The curb weight of the E93 increased due to the introduction of the retractable hardtop mechanism, typically 1600 to 1780 kg versus roughly 1450 to 1600 kg for the E46. This added weight enhances structural rigidity and safety but slightly impacts agility. Overall, the E93 offers more cabin space and modern features, balancing size growth with sporty dynamics.

During its 2007-2010 production, the BMW 3 Series Convertible (E93) competed with luxury convertibles like the Audi A4 Cabriolet and Mercedes-Benz C-Class Cabriolet. Dimensionally, the E93 is similar in length and width to these rivals, though often praised for its agile proportions. For example, the Audi A4 Cabriolet was slightly shorter (around 4,445 mm or 175 inches) with comparable width, while the Mercedes C-Class Cabriolet was similar in size but could be heavier depending on configuration. The E93’s retractable hardtop provided a niche advantage, combining coupe-like looks with convertible functionality, while its sporty dimensions enhanced driving enjoyment relative to some competitors.

The BMW 3 Series Convertible (E93) supports various rim sizes including 8J x 17, 8.5J x 17, 7J x 18, 8.5J x 18 rims. Tire sizes compatible include 225/45 R17, 255/40 R17, 255/35 R18, and 225/40 R18. Larger rims and wider tires typically enhance grip and handling performance, especially beneficial for spirited driving and cornering stability. However, they can result in a firmer ride quality due to lower profile tires and may increase road noise. The choice depends on owner preference for balance between sporty driving dynamics and comfort.
