2020 Alpina B5 Touring (G31, facelift 2020) Dimensions, Size & Specs

The curb weight of the Alpina B5 Touring (G31 facelift 2020) stands at 2155 kg (approximately 4750 lbs). This is the weight of the car without passengers or cargo but with standard equipment and all necessary operating consumables like fluids and a full fuel tank. The maximum weight capacity, which includes the vehicle's own weight along with passengers, cargo, and any additional load, is 2620 kg (about 5775 lbs). This indicates a useful payload capacity of around 465 kg (1025 lbs), balancing performance with practical utility for its station wagon class.

Regarding luggage capacity, the Alpina B5 Touring offers a generous 560 liters (approximately 19.8 cubic feet) of space when the rear seats are upright, making it practical for daily use, groceries, or moderate travel luggage. When the rear seats are folded down, the capacity expands significantly to 1700 liters (around 60 cubic feet). This expanded space allows for carrying much larger items or a higher volume of luggage, highlighting the vehicle's versatility as a high-performance station wagon suitable for both family and sport utility purposes.

The Alpina B5 Touring (G31 facelift 2020) is equipped with performance-oriented wheels and tires optimized for both handling and high-speed stability. The rims measure 20 inches with widths of 10J at the front and 8.5J at the rear, which provide a strong, sporty stance to the vehicle. The tire sizes are 285/30 ZR20 on the front wheels and 255/35 ZR20 on the rear wheels. These large and specially sized tires ensure enhanced grip, precise steering response, and support the car's powerful engine performance and dynamic driving characteristics.

Given its dimensions, the Alpina B5 Touring (G31 facelift 2020) should fit into most standard residential garages. The length of nearly 5 meters (4978 mm or around 16.3 feet) and width of approximately 1.87 meters (1868 mm or 6.1 feet) without mirrors are within typical garage sizes. However, with mirrors open, the width extends to 2126 mm (about 7 feet), so it’s advisable to fold the mirrors when parking in narrower garages. Its height of 1466 mm (about 4.8 feet) is also low enough to clear the majority of garage entrances. Owners should confirm garage internal dimensions and allow extra space for comfortable access.

Compared to its predecessor, the Alpina B5 Touring from the earlier generation, the G31 facelift 2020 generally maintains a similar size profile but with some refinements that enhance aesthetics and practicality. The length of the facelifted generation remains close to 4978 mm, which is typical for a full-size executive station wagon, ensuring ample interior room and luggage space. Changes might include slight variations in width or height due to design refreshes, but these are usually minimal. The facelift focuses on modernizing design and improving features without drastically altering the vehicle’s footprint.

In comparison to similar luxury performance station wagons like the Audi RS6 Avant and Mercedes-AMG E63 Estate, the Alpina B5 Touring (G31 facelift 2020) fits comfortably within the same size category. Its length of 4978 mm (about 196 inches) is competitive, providing generous interior and cargo space. Width and height are also comparable, with minor differences mainly due to brand-specific design choices and aerodynamic considerations. The Alpina tends to offer a slightly more understated exterior width without mirrors, while cargo capacity and usability often match or exceed rivals, emphasizing both performance and practicality.

The Alpina B5 Touring (G31 facelift 2020) distinguishes itself as a high-performance station wagon by blending powerful mechanics with luxurious comfort and practicality. It features a finely tuned engine delivering impressive power and torque, which, paired with advanced suspension and braking systems, ensures dynamic driving performance. The spacious wagon format offers a substantial luggage area with up to 1700 liters capacity with the seats folded, catering to versatility without sacrificing speed or agility. Alpina’s attention to detail, bespoke touches, and refined aesthetics further elevate it over standard models in the segment.

The Alpina B5 Touring’s choice of wheel and tire dimensions – 20-inch rims with 285/30 ZR20 tires at the front and 255/35 ZR20 at the rear – is critical for its performance character. The wider front tires provide substantial grip for handling and cornering stability, while the slightly narrower rear tires help balance traction and improve steering response. This staggered setup not only supports high-speed driving and lateral stability but also contributes to a comfortable ride despite the sporty tuning. It’s an optimal balance suited for a performance wagon designed to excel on both road and track.

Beyond its performance credentials, the Alpina B5 Touring (G31 facelift 2020) offers significant practical advantages for families. Its spacious interior comfortably seats five passengers with high-quality materials ensuring a luxurious experience. The generous luggage capacity of 560 liters (19.8 cubic feet) expands to 1700 liters (60 cubic feet) when the rear seats are folded, accommodating larger cargo or family gear for trips. The vehicle’s low height of 1466 mm facilitates easy entry and exit, and the advanced safety features provide peace of mind. It’s an excellent choice combining sportiness and family usability.
