The Alpina B3 (E46) produced from 1999 to 2005 has a length of 4471 mm (approximately 176.1 inches), a width of 1739 mm (about 68.4 inches), and a height ranging between 1395 mm to 1414 mm (around 54.9 to 55.7 inches). These dimensions provide a compact yet aggressive stance typical for sporty sedans of its class, ensuring good road presence without compromising maneuverability.

The curb weight of the Alpina B3 (E46) varies between 1450 to 1560 kg (approximately 3,197 to 3,439 lbs), while the maximum permissible weight ranges from 1950 to 2060 kg (around 4,299 to 4,543 lbs). The relatively moderate weight supports agile handling and responsive performance, fostering the sporty character Alpina is known for. The difference between curb and maximum permissible weight allows for passengers and cargo without significant detriment to dynamics.

The Alpina B3 (E46) offers a luggage capacity of 440 liters (about 15.5 cubic feet), which is quite competitive within the compact luxury sports sedan segment. This capacity provides practical storage space sufficient for everyday luggage, grocery runs, or weekend trips. When compared to similar sedans of its era, such as the BMW 3 Series (E46) standard variants, this capacity is slightly optimized or on par, making it a practical choice without sacrificing sportiness.

With a width of 1739 mm (68.4 inches) and a height ranging from 1395 mm to 1414 mm (54.9 to 55.7 inches), the Alpina B3 (E46) fits well within the dimensions of a typical single-car garage, which generally accommodates vehicles up to approximately 2400 mm (94.5 inches) wide and 2100 mm (82.7 inches) tall. Therefore, owners shouldn't encounter issues parking their B3 (E46) in a standard residential garage without modifications or difficulty.

The predecessor to the Alpina B3 (E46) would be earlier Alpina B3 versions based on the previous BMW 3 Series (E36). Compared to the E36-based B3, the E46 model is slightly larger and heavier, with an increase in length and width that improves interior space and road presence. The E46 version's curb weight varies up to 1560 kg, which may be slightly heavier due to added equipment and structural improvements aimed at enhancing safety and refinement, resulting in a more balanced and comfortable driving experience.

When compared to similar compact sports sedans from the late 1990s and early 2000s, such as the Audi S4 (B5 generation) or the Mercedes-Benz C32 AMG (W203 generation), the Alpina B3 (E46) is competitive in size. Its length of 4471 mm and width of 1739 mm place it in the middle of the pack, making it neither the largest nor smallest in its category. This balanced sizing allows it to maintain sporty agility while offering sufficient cabin and cargo space, distinguishing it within the performance luxury market.

The Alpina B3 (E46) comes equipped with rims sized 8J x 18 and 9J x 18 inches, paired with tire sizes of 225/40 ZR18 on the front and 255/35 ZR18 on the rear. These wide, low-profile tires contribute to improved grip and handling characteristics, especially during spirited driving and cornering. The staggered setup (wider tires on the rear) enhances traction and stability, which in combination with the Alpina-tuned suspension, provides a well-balanced, sporty driving experience.

The height variation between 1395 mm and 1414 mm (approximately 54.9 to 55.7 inches) on the Alpina B3 (E46) typically results from differences in suspension setups—such as optional sport suspensions, ride height adjustments, or tire sidewall heights. This minor height variation has negligible effect on interior comfort but can subtly influence aerodynamics and handling. A slightly lower ride height can improve stability and reduce drag, while a taller setup may offer marginally enhanced ride comfort on rough surfaces.

The Alpina B3 (E46) features a luggage capacity of 440 liters (15.5 cubic feet), which matches or slightly exceeds that of the standard BMW 3 Series E46 sedans. Despite its sportier tuning and added equipment increasing the curb weight (1450–1560 kg), it remains practical for daily use with enough trunk space for typical needs like grocery shopping or weekend trips. The balance between performance enhancements and practicality makes it a versatile choice for drivers seeking both excitement and usability.

The Alpina B3 (E46) distinguishes itself within the E46 generation by offering exclusive Alpina-specific tuning, including upgraded suspension, distinctive styling cues such as unique wheels (18-inch Alpina rims), and enhanced engine performance modifications. Produced from 1999 to 2005, it combines BMW’s well-regarded E46 chassis dynamics with Alpina’s precision craftsmanship and performance enhancements, resulting in a sedan that blends luxury, exclusivity, and sportiness. The B3 also offers refined interior appointments and a bespoke driving experience aligned with Alpina’s brand philosophy.
