The Alpina B3 Cabrio (E46) offers a luggage capacity of 300 liters (10.6 cubic feet). While not large compared to traditional sedans or SUVs, this capacity is reasonable for a luxury cabriolet, sufficient for weekend trips or daily errands. However, due to its sporty convertible design, the storage space is more limited, emphasizing style and driving dynamics over cargo utility.

The rim sizes include 8J X 18, 9J X 18, and 9J X 18, paired with tire sizes such as 225/40 ZR18, 255/35 ZR18, 225/40 R18, and 225/35 ZR18. These combinations provide optimal grip and performance while enhancing the vehicle’s aesthetic appeal typical of Alpina’s high standards.

With a width of 1757 mm (69.2 inches) and length of 4488 mm (176.7 inches), this cabriolet fits well within standard dimensions, leaving enough clearance for easy parking and opening of doors without difficulty.

Compared to its predecessor BMW 3 Series Cabriolet models of the E36 generation, the Alpina B3 Cabrio (E46) is slightly larger and more refined. The length increased to 4488 mm from about 4454 mm, and the width grew from roughly 1745 mm to 1757 mm, affording more cabin space and improved road presence. Height remained similar, allowing for a balanced sporty stance but enhancing comfort and modern styling.

The Alpina B3 Cabrio (E46) holds a competitive position among early 2000s luxury cabriolets such as the Audi S4 Cabriolet and Mercedes-Benz CLK. Dimensionally, it is slightly smaller in length and width than these rivals but offers superior driving dynamics and exclusivity with Alpina tuning. Its weight and luggage space are on par, but it stands out by blending precise German engineering with a distinct sporty character.

The height of the Alpina B3 Cabrio (E46) is 1352 mm (53.2 inches), which closely matches the standard BMW 3 Series E46 Cabriolet heights, typically around 1340-1360 mm. This similarity ensures the Alpina model preserves the classic low and aerodynamic profile characteristic of the E46 cabriolets, maintaining sleek looks while supporting optimized airflow for both performance and aesthetic appeal.

The Alpina B3 Cabrio (E46), with its length of 4488 mm and width of 1757 mm, strikes a balance between agility and stability. The relatively low height of 1352 mm lowers the center of gravity, which improves cornering and responsiveness.
