2023 Alpina B3 Touring (G21, facelift 2022) Dimensions, Size & Specs

The Alpina B3 Touring has a curb weight of 1955 kg (4,309 lbs), which is the weight of the vehicle without passengers or cargo but with all necessary fluids and a full tank of fuel. The maximum weight, which includes passengers, cargo, and any additional load, is rated at 2430 kg (5,358 lbs). This substantial weight reflects the vehicle's robust build and high-quality materials, supporting its performance and luxury characteristics.

This model provides a luggage capacity of 500 liters (17.7 cubic feet) when the rear seats are in the upright position. When you fold the rear seats down, the luggage space expands significantly to 1510 liters (53.3 cubic feet). This makes the Alpina B3 Touring exceptionally versatile for everyday use and longer trips, accommodating a wide variety of cargo sizes with ease.

The Alpina B3 Touring's dimensions, being 4723 mm long and 2068 mm wide with mirrors open, generally fit within the common standard garage dimensions. A typical US standard garage measures about 6 meters (20 feet) deep and 3 meters (10 feet) wide per car, so the B3 Touring fits comfortably lengthwise, and width-wise you should be cautious with mirrors folded when maneuvering. The height of 1438 mm also poses no problem for typical garage clearance, making it practical for most home garages.

Compared to its predecessor, the Alpina B3 Touring (prior generation F31), the G21 facelift model is slightly larger in length and width, offering a roomier interior and cargo space. The curb weight has also increased somewhat due to updated features and enhancements in materials, stability, and safety. The new generation focuses on improving both the dynamic performance and comfort, making it a more refined station wagon while retaining Alpina’s signature sporty feel.

Against rivals such as the Audi RS4 Avant or Mercedes-AMG C63 Estate, the Alpina B3 Touring holds a competitive position in terms of size. While it shares similar length and width dimensions, Alpina's unique tuning and build offer a slightly higher curb weight but also increased luggage capacity. Its blend of luxury and sportiness sets it apart, with the luggage volumes and overall dimensions providing practicality on par or sometimes superior to these competitors.

The Alpina B3 Touring comes equipped with 19-inch rims sized 9.5J x 19 at the front and 8.5J x 19 at the rear. Correspondingly, the tire dimensions are 265/35 R19 on the front and 255/35 R19 at the rear. These wide, low-profile tires contribute to the car's excellent handling characteristics and sporty appearance, enhancing grip and responsiveness typical of Alpina's performance tuning.

The variable luggage capacity of the Alpina B3 Touring, offering 500 liters (17.7 cubic feet) with seats up and expanding to 1510 liters (53.3 cubic feet) with rear seats folded down, allows for remarkable flexibility. This is practical for daily commutes, family trips, or transporting larger goods. The easy folding mechanism in the rear seats enables quick transitions from passenger to cargo space, making the vehicle well-suited for versatile lifestyles without sacrificing performance.

At 1438 mm (56.6 inches) in height, the Alpina B3 Touring maintains a low and aerodynamic profile for a station wagon. This relatively low stance enhances its driving dynamics by lowering the center of gravity, improving stability and handling, especially at higher speeds and around corners. Practicality-wise, this height is low enough to allow easy entry and exit, yet high enough to offer good visibility and reasonable interior headroom without the bulkiness of taller SUVs.

The Alpina B3 Touring is a luxury high-performance station wagon produced between 2022 and 2024. It combines the agile handling and power of a sports sedan with the practicality of an estate car, making it a versatile choice for enthusiasts who need both speed and space. With its facelift in 2022, it features refined styling and advanced technology, maintaining Alpina’s signature blend of exclusivity, performance, and everyday usability.
