The Alpina B4 Gran Coupe (G26), produced between 2022 and 2024, measures 4792 mm (188.7 inches) in length, 1850 mm (72.8 inches) in width, and stands 1440 mm (56.7 inches) tall. These dimensions create a sleek and sporty coupe profile that balances a substantial road presence with aerodynamic efficiency. Its width expands to 2073 mm (81.6 inches) when mirrors are opened, which is important to consider for tight spaces and parking. Overall, these dimensions position the B4 Gran Coupe as a larger coupe in its class, with a low height contributing to a dynamic stance and enhanced performance characteristics on the road.
The curb weight of the Alpina B4 Gran Coupe (G26) is 1965 kg (4,331 pounds), which reflects the weight of the vehicle including all standard equipment, necessary operating consumables like oil and a full tank of fuel, but without passengers or cargo. The maximum permissible weight, including passengers and cargo, is 2400 kg (5,291 pounds). This weight balance ensures the car combines strong performance capabilities with solid structural integrity and safety. The B4 Gran Coupe's weight is typical of luxury performance coupes in its segment, indicating the use of premium materials and technologies to maintain rigidity and dynamic driving characteristics.
The Alpina B4 Gran Coupe (G26) provides a luggage capacity of 470 liters (16.6 cubic feet) with the rear seats in their standard upright position. This is a respectable amount of space for a coupe, allowing for practical storage of suitcases, shopping bags, or sports gear. When the rear seats are folded down, the luggage capacity significantly increases to 1290 liters (45.5 cubic feet), offering enhanced versatility for larger items, longer trips, or carrying bulky cargo. This dual-option storage capacity makes the B4 Gran Coupe practical for daily use as well as weekend getaways, blending style with functionality.
The Alpina B4 Gran Coupe (G26) is equipped with larger performance-oriented wheels and tires tailored for driving dynamics and style. The rims come in sizes of 10J x 20 inches at the front and 8.5J x 20 inches at the rear, providing both a strong visual appeal and improved grip. The corresponding tire sizes are 285/30 R20 for the rear and 255/35 R20 for the front. These wide, low-profile tires contribute to enhanced cornering, traction, and road feel, which is essential for a sporty coupe with the Alpina badge, known for blending performance and luxury.
The Alpina B4 Gran Coupe (G26), with a length of 4792 mm (188.7 inches) and a width of 1850 mm (72.8 inches) without mirrors, fits comfortably into most standard garages. However, when considering the width with opened mirrors, which extends to 2073 mm (81.6 inches), it becomes essential to ensure that the garage allows for this extra width clearance. Standard garage widths typically range from 2400 mm (94.5 inches) to 3000 mm (118 inches), so the B4 Gran Coupe will fit in a typical single-car garage but may require careful maneuvering to avoid contact with walls or objects near the sides. Ensuring mirror clearance is especially important for parking in tighter urban or older garages.
Compared to its predecessor, the Alpina B4 Gran Coupe (F33 generation), the G26 model exhibits a noticeable increase in dimensions. The length of the G26 at 4792 mm (188.7 inches) is longer, and the width, at 1850 mm (72.8 inches) closed, is slightly wider, offering more interior space and a more commanding road presence. The newer generation also enjoys a lower height of 1440 mm (56.7 inches) compared to earlier models, which contributes to a sportier aerodynamic profile. This size evolution not only improves passenger comfort and cargo capacity but also enhances the vehicle’s stance and handling dynamics. Overall, the G26 reflects modern design trends towards larger, more spacious luxury sport coupes without compromising on dynamic appeal.
In comparison to other luxury performance coupes like the BMW M4 (G82) and Audi S5 Sportback, the Alpina B4 Gran Coupe (G26) demonstrates competitive yet slightly more spacious dimensions. Its length of 4792 mm (188.7 inches) provides a slightly longer wheelbase and overall size relative to many rivals, contributing to a more comfortable rear seat and trunk space. Width-wise, at 1850 mm (72.8 inches), it is in line with segment competitors, although the opened mirror width of 2073 mm (81.6 inches) is slightly wider than some, requiring mindful parking. The luggage volume of 470 liters (16.6 cubic feet) with seats up makes it very practical for a coupe, often surpassing competitors with tighter storage. Overall, the B4 Gran Coupe blends luxurious and spacious dimensions with distinctive Alpina styling and performance focus.
With a curb weight of 1965 kg (4,331 lbs) and a length of 4792 mm (188.7 inches), the Alpina B4 Gran Coupe (G26) is on the heavier side for performance coupes, but this weight contributes to a solid and well-planted driving experience. The increased size and weight compared to lighter coupes improve ride comfort and stability at high speeds, while Alpina’s suspension tuning and engineering compensate for the larger footprint by delivering sharp handling and agility. The broad track and wide tires (285 mm rear, 255 mm front) also help maintain cornering performance despite the extra kilo. Overall, the size and weight create a harmonious balance of luxury comfort and dynamic capability, a hallmark of Alpina vehicles.
The Alpina B4 Gran Coupe (G26) stands at a height of 1440 mm (56.7 inches), making it relatively low compared to standard sedans but typical for a sporty coupe. This lower height improves aerodynamics and stability, contributing to better performance and driving dynamics. However, it may pose challenges when entering or exiting steep driveways or speed bumps where ground clearance might be limited. The car’s design prioritizes a low center of gravity, so while it may not be ideal for rough terrains, it excels on smooth roads and highways. For everyday use, the height strikes a balance between sporty aesthetics and practical usability.
The factory-equipped rim sizes on the Alpina B4 Gran Coupe (G26) are 10J x 20 inches at the front and 8.5J x 20 inches at the rear, paired with 255/35 R20 tires on the front and 285/30 R20 tires on the rear, reflecting staggered sizing for optimized grip and handling. When considering replacements or upgrades, it is crucial to maintain these specifications or equivalent sizes to preserve the intended driving dynamics and safety. Upgrading to lighter alloy wheels within the same diameter can help reduce unsprung weight, while maintaining the tire width and profile ensures consistent traction and ride comfort. Professional consultation is recommended to confirm compatibility with the vehicle’s suspension and brake components.
