These compact sports coupe dimensions contribute to its nimble handling and classic aesthetic, characteristic of the E30 platform on which it is based.

The Alpina B6 (E30) has a wheelbase of 2,570 mm (101.2 inches). This wheelbase strikes a balance between responsive handling dynamics and adequate interior space for a coupe. A moderate wheelbase like this allows for tight cornering and agility, which is advantageous in sporty driving, while still maintaining reasonable comfort for occupants in the front and rear seats.

The curb weight of the Alpina B6 (E30) is approximately 1,310 kg (2,888 lbs). This relatively light weight, combined with its powerful engine tuning by Alpina, helps in delivering strong acceleration and agile handling. The lighter mass improves overall vehicle dynamics, fuel efficiency, and driving responsiveness, making it a highly enjoyable performance coupe of its era.

The Alpina B6 (E30) stands about 1,335 mm (52.6 inches) tall. This relatively low height contributes to its sporty silhouette and lowers the center of gravity, enhancing aerodynamic efficiency and stability at speed. While contributing to the coupe's sleek look, the height balances cabin headroom with performance considerations, making the interior comfortable for occupants without compromising styling and driving dynamics.

With a width of around 1,670 mm (65.7 inches), the Alpina B6 (E30) provides a stable and planted stance on the road. This moderate width enhances cornering stability and helps offer reasonable shoulder room inside the cabin. It's wide enough to help with high-speed stability while maintaining a compact footprint, suitable for maneuvering urban environments and parking.

Yes, the Alpina B6 (E30) fits comfortably into a standard residential garage. With its length measuring 4,320 mm (170.1 inches) and width of 1,670 mm (65.7 inches), it falls within typical garage clearance dimensions. Most standard single garages measure about 6,000 mm (236 inches) in length and 3,000 mm (118 inches) in width, so the B6 offers ample space for entry, exit, and some extra room for opening doors and storage around the vehicle.

The Alpina B6 (E30) is based on the same E30 platform as the standard BMW 6 Series models of the time but features sportier tuning and enhancements. Size-wise, the B6 shares very similar dimensions with the base E30 6 Series coupe—about 4,320 mm (170.1 in) in length and 1,670 mm (65.7 in) wide. However, Alpina upgrades its performance significantly with engine tuning and suspension tweaks, offering higher power output and improved handling characteristics, making it a more performance-focused variant without changing the exterior footprint.

The Alpina B6 (E30) shares the E30 chassis and thus is similar in size to other E30 models like the BMW M3 produced in the late 1980s. While the M3 is slightly shorter and lighter, the B6 has dimensions approximately 4,320 mm (170.1 in) length and 1,670 mm (65.7 in) width, quite close to the M3’s roughly 4,240 mm (167 in) length and 1,700 mm (66.9 in) width. The primary difference lies in tuning and intended use; the B6 focuses on a blend of luxury and performance, while the M3 is more track-oriented.

The Alpina B6 (E30) typically comes with a fuel tank capacity around 70 liters (approximately 18.5 US gallons). This moderately sized tank allows for a decent driving range, balancing weight considerations with the need for fewer refueling stops. Given the performance-oriented engine tuning, fuel consumption may be higher than standard sedans but still practical for both spirited driving and longer trips.

As a 2-door coupe, the Alpina B6 (E30) primarily accommodates four passengers, though rear seat space is somewhat limited compared to larger sedans. The interior cabin is designed for driver engagement with supportive sport seats up front. Cargo space is modest but sufficient for its class, with a trunk volume typically around 380 liters (13.4 cubic feet), suitable for day-to-day luggage or shopping but not designed for large cargo loads.
