1989 BMW 8 Series (E31) Dimensions, Size & Specs

The BMW 8 Series (E31) has a curb weight ranging from approximately 1780 kg to 1900 kg (3924 to 4189 lbs), depending on specific model variants and equipment. The maximum permissible weight (gross vehicle weight rating) ranges between 2180 kg and 2340 kg (4805 to 5157 lbs). This weight range ensures a strong balance between solidity, performance, and luxury typically expected from a grand touring coupe.

This grand tourer offers a luggage capacity between 320 and 360 liters (11.3 to 12.7 cubic feet), which is quite reasonable for a luxury coupe of its class. The trunk space is designed to accommodate typical luggage for long-distance travel, making it practical despite the sleek two-door coupe layout. This capacity ensures sufficient room for weekend trips or light travel without compromising the car’s sporty design.

Yes, the BMW 8 Series (E31) generally fits in a standard residential garage, but it is close to the upper limits due to its length of 4780 mm (188.2 inches) and width including mirrors of 2037 mm (80.2 inches). Standard garage dimensions are typically around 2.4 to 2.7 meters wide and about 5 to 6 meters long. The E31’s low height (1330-1340 mm or 52.4-52.8 inches) is not a concern. However, owners should measure their garage width carefully to ensure adequate clearance with mirrors open.

The BMW 8 Series (E31) has a ride height or ground clearance of 140 mm (5.5 inches). This relatively low ground clearance is typical for luxury grand touring coupes designed for enhanced road handling, aerodynamics, and sporty driving dynamics. While it improves performance and aesthetics, drivers should be mindful of speed bumps and uneven road surfaces to avoid potential undercarriage contact.

The E31 comes equipped with rim sizes typically ranging from 16 to 17 inches, specifically 7.5J x 16, 7.5J x 17, and variations thereof. Tire sizes include 235/50 R16, 235/45 R17, 265/40 R17, and 235/50 ZR 16. These sizes contribute to the car’s sporty stance and enhance performance, handling, and ride quality. The 17-inch rims especially support higher grip and responsive handling due to wider and lower-profile tires.

The BMW 8 Series (E31) succeeded the BMW 6 Series (E24) in terms of flagship high-performance coupe status, although technically it was a new model line rather than a direct generation replacement. Compared to the E24 6 Series, the E31 was longer by approximately 280 mm (11 inches) and wider, with a lower profile height. This gave the E31 a more modern, aerodynamic silhouette with improved interior space and luxury features. It was a step up in size and technology, emphasizing grand touring comfort and performance.

The BMW 8 Series (E31) is comparable in size to other luxury grand touring coupes of the 90s, such as the Mercedes-Benz SL-Class (R129) and Jaguar XJ-S. The E31 is notably longer than many competitors at 4780 mm (188.2 inches), offering a commanding road presence. Its width and low height also emphasize sportiness paired with luxury. While some rivals may offer slightly more interior volume, the E31’s focus was on balancing size with aerodynamic efficiency and driving dynamics.

The BMW 8 Series (E31) was produced from 1989 until 1999, representing BMW’s flagship coupe offering for the decade. It was available exclusively as a two-door coupe, highlighting its design focus on sportiness and luxury. The E31 marked BMW’s first use of advanced technology like the multi-link rear suspension and a V12 engine in a coupe format, emphasizing grand touring performance and prestige.

The roof load capacity of the BMW 8 Series (E31) is 75 kg (165 lbs). This value represents the maximum weight that can be safely carried on the roof, such as roof racks or cargo boxes. For a sleek coupe like the E31, this capacity is sufficient for light cargo carriers or sports equipment. However, due to the vehicle's aerodynamic design, roof load should be used cautiously to avoid adverse effects on handling and fuel efficiency.
