1988 BMW M3 Convertible (E30) Dimensions, Size & Specs

The curb weight of the BMW M3 Convertible (E30) is around 1360 kg (approximately 2998 lbs), which refers to the weight of the vehicle without passengers or cargo but including all standard equipment and necessary operating consumables like oil and fuel. The maximum permissible weight, or gross vehicle weight rating (GVWR), for this model is 1720 kg (about 3792 lbs). This specification ensures safe operation when the vehicle is loaded with passengers and cargo, balancing performance with safety standards. The relatively light curb weight helps deliver responsive handling and dynamic driving characteristics.

The E30 BMW M3 Convertible offers a luggage capacity of 303 liters (approximately 10.7 cubic feet). While this volume is modest compared to larger modern convertibles or sedans, it is quite practical considering the vehicle’s sports car focus and compact dimensions. The 303-liter trunk space can comfortably store everyday items such as groceries, small suitcases, or weekend bags, making it suitable for typical daily driving or short trips. However, due to the convertible roof mechanism, the space is optimized more for light storage than extensive cargo hauls.

Yes, the BMW M3 Convertible (E30) can fit comfortably into a standard garage. With a length of 4345 mm (171.1 inches), a width of 1680 mm (66.1 inches), and height of 1370 mm (53.9 inches), it occupies a relatively modest footprint compared to many contemporary vehicles. Most standard garages are designed to accommodate cars up to around 5 meters in length and 2.5 meters in width, so the E30 falls well within these dimensions, allowing for ample space to open doors and move around the vehicle inside the garage.

The BMW M3 Convertible (E30) is equipped with 15-inch rims paired with tire sizes of 205/55 R15. These dimensions are standard for sports cars of its era and contribute significantly to its handling and ride quality. The 205 mm tire width provides a good contact patch with the road, enhancing grip during aggressive cornering and dynamic driving. The aspect ratio of 55 balances comfort with tire sidewall stiffness, improving steering response without overly compromising ride softness. Together, these specifications ensure a spirited driving experience that supports the car's sporty intentions.

The BMW M3 Convertible (E30) is a special variant of the first-generation M3 coupe, which was introduced in the early 1980s. The convertible version maintains very similar dimensions to the original M3 coupe, with a length of 4345 mm (171.1 inches) and width of 1680 mm (66.1 inches). The height of 1370 mm (53.9 inches) is also consistent with the coupe, though the convertible adds modest weight due to structural reinforcements necessary for an open-top design, bringing the curb weight to about 1360 kg (2998 lbs). Overall, while the dimensions are largely unchanged, the convertible offers a unique driving experience with open-air motoring without sacrificing much of the original sporty character.

In comparison to similar high-performance convertibles from the late 1980s and early 1990s, such as the Mercedes-Benz 190E 2.3-16 Convertible or Porsche 911 Cabriolet of the era, the BMW M3 Convertible (E30) features competitive compact dimensions with a length of 4345 mm (171.1 inches), width of 1680 mm (66.1 inches), and height of 1370 mm (53.9 inches). Its weight of 1360 kg (2998 lbs) keeps it sufficiently light for agile handling, which is a hallmark of the M3 series. Performance-wise, the M3 Convertible balances power, handling, and the thrill of a drop-top design better than many of its contemporaries, making it a revered classic among enthusiasts seeking a blend of sportiness and open-air driving.

The BMW M3 Convertible (E30) is designed as a cabriolet, meaning it is a convertible with a manually or electrically retractable soft top roof, providing an open-air driving experience. This body style enhances the driving pleasure, especially during good weather, but somewhat reduces trunk volume compared to the coupe due to roof storage space and structural reinforcements for safety. Despite this, the convertible maintains a respectable luggage capacity at 303 liters (10.7 cubic feet), ensuring it remains practical for daily use and weekend trips.

The BMW M3 Convertible (E30) originally comes with 15-inch rims paired with tires sized 205/55 R15. These specifications were standard for sporty vehicles in the late 1980s, offering a blend of performance and ride comfort. Today, these sizes are still widely available, and modern tire technology offers improved grip, durability, and safety compared to those from the car's production period. Owners looking to maintain originality while enhancing performance can find numerous options from today's top tire manufacturers that fit these specifications perfectly.

With a height of 1370 mm (53.9 inches) and a width of 1680 mm (66.1 inches), the BMW M3 Convertible (E30) features a low and relatively narrow stance, typical of performance-oriented vehicles of its time. This low height reduces aerodynamic drag and lowers the center of gravity, enhancing stability and handling in corners. The moderate width provides a balanced footprint that aids in precision steering and responsive road feel without making the car unwieldy in urban environments. Together, these dimensions contribute to a strong, sporty road presence while supporting efficient airflow over and around the vehicle.
