Additionally, the balance between a broad body and relatively low profile creates an elegant silhouette that is a signature of the Alpina tuning philosophy, blending performance with luxury aesthetics.

Despite its substantial curb weight of 2020 kg (4,454 lbs), the Alpina B6 Cabrio (F12) offers a refined and dynamic driving experience.

Its 300-liter (10.6 cubic feet) luggage capacity is competitive, and the option to fold rear seats for slight space increase is a practical advantage. The B6 Cabrio's combination of size, weight, and performance tuning offers a distinctive blend of luxury, space, and driving excitement that makes it stand out in its segment.
