2023 Alpina B8 Gran Coupe (G16 LCI, facelift 2022) Dimensions, Size & Specs

With the mirrors extended, the Alpina B8 Gran Coupe reaches a width of 2137 mm (84.1 inches). This relatively wide stance requires more attention when parking or navigating through narrow spaces. It might be challenging to park in very tight spots, but typical garage spaces or wider parking spots can accommodate it comfortably, especially with careful maneuvering.

The luggage capacity of the Alpina B8 Gran Coupe is 440 liters (approximately 15.5 cubic feet). This allows for adequate storage for daily commuting, weekend getaways, or even longer trips. While not the largest in its class due to its coupe styling, the trunk space remains practical for most passengers, able to accommodate suitcases, shopping bags, or sports equipment with reasonable ease.

The Alpina B8 Gran Coupe features distinctive rim sizes of 10J x 21 for the front and 8.5J x 21 for the rear wheels. It comes with large tires sized 285/30 ZR21 on the front and 245/35 ZR21 on the rear. These wider tires ensure improved grip, handling stability, and enhanced road presence, fitting well with the car’s sporty yet luxurious driving dynamics.

At 1428 mm (56.2 inches) tall, the Alpina B8 Gran Coupe maintains a sleek, low-profile coupe design that enhances aerodynamics and reduces drag for better performance and fuel efficiency. This height supports a sporty silhouette while also ensuring sufficient headroom for passengers, contributing to comfort without compromising on dynamic styling.

Yes, the Alpina B8 Gran Coupe can generally fit into a standard residential garage. Standard garages usually provide at least 2.4 meters (7.9 feet) in width and 5.4 meters (17.7 feet) in length. With the B8's length of 5092 mm (200.5 inches, or roughly 5.1 meters) and width without mirrors at 1932 mm (76.1 inches), it fits comfortably. However, care must be taken with the mirrors extended (2137 mm or 84.1 inches) to ensure no contact with sides, especially in tighter spaces.

Compared to the predecessor generation, the 2023 Alpina B8 Gran Coupe (G16 LCI, facelift 2022) maintains similar fundamental dimensions but offers refinements in design and technology. The facelift introduced updated front and rear styling, enhanced interior luxury features, and some aerodynamic improvements that subtly affect its stance. Overall length and width have seen little change, preserving its grand touring comfort while injecting modern styling and tech upgrades that set it apart from its predecessor.

The Alpina B8 Gran Coupe is slightly larger and heavier than many competitors in the luxury performance coupe segment. With a curb weight of 2100 kg (4629 lbs) and length exceeding 5 meters (200.5 inches), it emphasizes grand touring luxury alongside performance. Comparable models from rivals may be lighter or more compact, but the B8's generous dimensions provide additional interior space and trunk capacity, combining powerful engine performance with distinct Alpina customization and comfort.

The maximum weight of the Alpina B8 Gran Coupe is 2600 kg (5732 lbs), which includes the curb weight plus passengers, luggage, and any additional load. This means it can safely carry approximately 500 kg (1102 lbs) beyond its own weight, balancing performance and safety. Owners should be mindful not to exceed this limit to maintain driving stability, suspension performance, and braking efficiency, especially given the car's powerful engine and sporty chassis setup.

The Alpina B8 Gran Coupe shares its platform with the BMW 8 Series Gran Coupe but distinguishes itself primarily through its added width and custom suspension settings tailored for a unique ride quality. While exterior dimensions are very close, Alpina's version usually offers a slightly heavier weight due to enhanced luxury components, larger tires, and specialized hardware. These factors translate into a ride and handling character different from the standard BMW, where Alpina emphasizes refined grand touring comfort combined with a performance edge, rather than a purely sporty approach.
