Yes, the Alpina D3 Touring (G21) generally fits into a standard residential garage. Most garages have a width ranging from 2400 to 3000 mm (94 to 118 inches) and a height of around 2130 to 2440 mm (84 to 96 inches). Since the car measures 1827 mm (71.9 inches) in width and 1438 mm (56.6 inches) in height, it will comfortably fit inside standard garages with ample room for opening doors and maneuvering within the space.

The Alpina D3 Touring (G21) is equipped with 19-inch rims, sized 9.5J for the front and 8.5J for the rear. The tires measure 265/35 ZR19 at the front and 255/35 ZR19 at the rear. These wide and low-profile tires enhance grip, cornering stability, and overall driving dynamics, contributing to the vehicle’s sporty character while still maintaining ride comfort appropriate for a premium station wagon.

Compared to its predecessor, the Alpina D3 Touring (previous generation), the G21 generation features subtle size improvements and refinements. Typically, newer generation station wagons like the G21 grow slightly longer and wider for increased interior space and practicality. While exact predecessor dimensions vary by model year, the G21's length of 4719 mm and width of 1827 mm generally translate to a better balance of interior room and exterior agility compared to older models, alongside upgrades in technology and chassis dynamics.

When compared to other premium mid-size station wagons, the Alpina D3 Touring (G21) stands comfortably in the typical size range. For example, the BMW 3 Series Touring, often considered a benchmark in this segment, shares very similar dimensions, while competitors like the Audi A4 Avant or Mercedes C-Class Estate have comparable lengths and widths. Its 4719 mm length and 1827 mm width make it competitive, offering a balance of cabin space and driving dynamics suited to sporty yet practical usage.

While precise interior volume figures for the Alpina D3 Touring (G21) are less commonly specified, the overall dimensions (length 4719 mm and width 1827 mm) allow for comfortably spacious seating for five passengers. The lower height of 1438 mm supports a sleek profile but still provides sufficient headroom and legroom, especially for front and rear occupants. Its station wagon layout also helps maximize usable cabin and cargo space compared to sedans, making it versatile for both passenger comfort and cargo capacity.

Specific ground clearance data isn't typically standardized for Alpina variants, but considering the 19-inch wheel setup and sporty suspension tuning, the Alpina D3 Touring (G21) likely has a moderate ground clearance typical for sport-oriented station wagons, around 130-150 mm (5.1-5.9 inches). This balance allows it to maintain agility and aerodynamic efficiency on paved roads while still handling mild road irregularities and everyday driving conditions without trouble.

The Alpina D3 Touring (G21) excels in combining the sporty performance of an Alpina-tuned vehicle with the practicality expected of a modern station wagon. Its generous luggage capacity of 500 liters with seats up, expanding to 1510 liters with rear seats folded, offers exceptional cargo flexibility for family trips, sports equipment, or even professional use. Coupled with its reasonably compact exterior dimensions—easy to maneuver in urban settings and fit into standard garages—it strikes a fine balance between everyday usability and dynamic driving pleasure.
