The maximum permissible weight, which includes passengers and cargo, is 2400 kilograms (5291 pounds). This weight balance provides the Alpina B3 with excellent handling and performance characteristics while offering the robustness and safety expected from a high-performance luxury sedan.
The Alpina B3 Sedan (G20) offers a luggage capacity of 480 liters (approximately 16.9 cubic feet). This is a competitive volume within the luxury compact sedan category, providing ample space for travel bags, groceries, or everyday items. The trunk space balances practicality with sportiness, allowing owners to enjoy performance driving without sacrificing cargo-carrying capability typical of family or executive vehicles.
The Alpina B3 Sedan (G20) comes equipped with rims sized 9.5J x 19 inches for the front and 8.5J x 19 inches for the rear. The tire sizes complement these rims with 265/35 ZR19 for the front and 255/35 ZR19 for the rear.

This width excels in balancing athletic performance with luxury comfort.
The Alpina B3 Sedan (G20) stands at a height of 1440 mm (56.7 inches).

Additionally, the sleek height contributes to a sporty silhouette, enhancing the car’s visual appeal while ensuring it remains practical for urban and highway use.
