The curb weight of the Alpina B8 Gran Coupe is 2175 kg (4795 lbs), while its maximum allowable weight is 2600 kg (5732 lbs). The considerable weight underscores its robust build and luxury features but also impacts fuel efficiency and handling. Despite this, Alpina engineering ensures the car remains agile and powerful.

With a width of 1932 mm (76.1 inches) without mirrors and 2137 mm (84.1 inches) with mirrors open, and a length of 5092 mm (200.5 inches), the B8 Gran Coupe fits comfortably inside, although care must be taken when accommodating its wider stance with mirrors open.

Compared to its predecessor, the Alpina B8 Gran Coupe (G16) generally features modest dimensional changes, maintaining a similar footprint with slight refinements for improved aesthetics and interior space. The G16 generation enhances performance and technology while keeping the length near 5 meters and width around 1.9 meters, ensuring that fans of the previous generation will find continuity in size with noticeable upgrades.

The Alpina B8 Gran Coupe fits into the luxury grand tourer segment with dimensions competitive against rivals like the BMW M8 Gran Coupe and Audi RS7. Its 5092 mm length and 1932 mm width make it one of the more spacious coupes, while its weight of over 2.1 tons places it among the heavier, more substantial offerings. This results in a commanding presence on the road, combining luxury coupe aesthetics with practical volume.

Prospective buyers should consider the overall length (5092 mm/200.5 in) for parking and maneuvering, as well as the width with mirrors (2137 mm/84.1 in), which affects garage fit and tight spaces. The low ground clearance (135 mm/5.3 in) is great for performance but may limit use on rough roads. Additionally, curb weight at 2175 kg (4795 lbs) suggests robust build quality but potential impacts on fuel consumption. Lastly, luggage capacity of 440 liters offers practical utility for a luxury coupe, making it a well-rounded choice balancing style, space, and daily usability.
