2018 BMW 8 Series (G15) Dimensions, Size & Specs

The width of the BMW 8 Series (G15) Coupe, excluding mirrors, is 1902 mm (about 74.8 inches). When you include the opened side mirrors, the width increases to 2137 mm (approximately 84.1 inches). This expanded width with mirrors is important to consider for parking or navigating tight spaces.

The BMW 8 Series (G15) Coupe stands between 1341 mm and 1346 mm tall, roughly 52.8 to 53 inches. This low height underlines its sporty and aerodynamic design, enhancing stability at high speeds and contributing to the sleek, aggressive stance that characterizes this luxury grand tourer.

The curb weight of the BMW 8 Series (G15) ranges from 1710 kg to 1930 kg (about 3,770 to 4,255 pounds). This weight range depends on the specific model and options but strikes a balance between solid road presence and agility. The weight contributes to a comfortable yet sporty driving experience, with advanced suspension systems mitigating any bulk.

The BMW 8 Series (G15) has a maximum weight range between 2225 kg and 2410 kg (approximately 4,906 to 5,314 pounds). This figure accounts for the vehicle with maximum payload, including passengers, cargo, fuel, and optional equipment. Staying within this limit ensures safety and optimal vehicle performance.

The luggage capacity of the BMW 8 Series (G15) stands at 420 liters (around 14.8 cubic feet). This is quite generous for a luxury coupe, allowing adequate storage for weekend getaways or longer trips. The space is well-shaped, making it convenient to accommodate suitcases and smaller items, although the coupe's sloping roofline limits vertical space compared to sedans or SUVs.

The ground clearance of the BMW 8 Series (G15) ranges from 121 mm to 128 mm (about 4.8 to 5 inches). This relatively low ride height supports sporty handling and aerodynamic efficiency but can pose challenges over speed bumps or rough roads. Owners should drive with caution on uneven terrain to avoid scraping the underside.

Yes, the BMW 8 Series (G15) generally fits into a standard garage, but space can be tight depending on the garage size. With a length just under 4.85 meters (about 15.9 feet) and width including mirrors around 2.14 meters (7.0 feet), you'd want a garage at least 6 meters (20 feet) deep and 2.5 meters (8.2 feet) wide to comfortably park and open doors without obstruction.

Compared to its predecessor, the E31 8 Series (produced from 1989 to 1999), the G15 model is larger in every critical dimension, reflecting modern luxury and safety standards. The G15 is about 4843-4851 mm long versus roughly 4700 mm for the E31. Width including mirrors also increased, and the contemporary lines are sleeker with more aggressive aerodynamics. The weight is notably higher due to enhanced construction and technology but offers significantly improved performance and refinement.

The BMW 8 Series (G15) is competitive with luxury grand tourers like the Mercedes-Benz S-Class Coupe and Audi A8 Coupe (when available). Dimensionally, it sits in a similar range, offering a balance of length, width, and height conducive to sporty yet comfortable driving. The luggage capacity and curb weight also match well with these peers, and its advanced dynamics and tech package make it a standout in the segment. Its combination of luxury, sportiness, and practicality positions it strongly among German rivals.
