2021 BMW M3 (G80) Dimensions, Size & Specs

A standard garage typically measures around 2.4 meters (8 feet) in width and 5.5 to 6 meters (18 to 20 feet) in length. The BMW M3 (G80), with a width including opened mirrors of 2068 mm (81.4 inches or about 2.07 meters), fits comfortably within the width of most standard garages, leaving some clearance for opening doors or walking around. Its length of approximately 4795 mm (188.8 inches or about 4.8 meters) also fits well within average garage length dimensions. Therefore, the M3 (G80) should fit into a standard-sized garage without significant issues, though care must be taken with mirror clearance when parking.

The BMW M3 (G80) weighs between 1705 kg and 1780 kg (3759 to 3924 lbs) at curb weight, with a maximum permissible weight of 2210 to 2260 kg (4872 to 4980 lbs). This relatively moderate weight for a high-performance sedan contributes to its agility and driving dynamics, allowing for precise handling, rapid acceleration, and responsive steering. The weight balance, combined with a powerful engine and sport-tuned suspension, ensures the M3 offers excellent cornering stability and traction. While heavier than smaller sports cars, the M3 maintains a dynamic feel without compromising comfort or structural rigidity.

The BMW M3 (G80) offers a luggage capacity of 480 liters (approximately 16.9 cubic feet), which is quite generous for a sports sedan. This volume allows for several suitcases or grocery bags, making it practical for both daily errands and longer trips. Despite its focus on performance, the M3 maintains a functional trunk space that caters well to drivers who require sportiness without sacrificing usability. Compared to other cars in the high-performance sedan segment, the M3 stands out for combining performance with practicality.

The BMW M3 (G80) has a ride height or ground clearance of between 120 and 123 mm (4.7 to 4.8 inches). This relatively low ground clearance is typical for performance sedans and contributes to improved aerodynamics, handling, and stability at higher speeds. However, it also means that the M3 is less suited to rough or uneven terrain and requires cautious driving over speed bumps, steep driveways, or potholes to avoid scraping the underside. On smooth city and highway roads, the clearance is suitable and balances sporty driving with daily usability.

The BMW M3 (G80) comes with a variety of tire and rim sizes ranging from 18 to 20 inches. Rim sizes include 10.5J x 19, 9.5J x 18, 10.5J x 20, and 9.5J x 19, paired with tire sizes such as 285/35 ZR19 103Y XL, 275/40 ZR18 103Y XL, 285/30 R20, 275/35 R19, 285/30 ZR20 99Y XL, and 275/35 ZR19 100Y XL. The larger rims and performance tires enhance grip, cornering ability, and braking performance, while also contributing to the car's aggressive stance. Different tire profiles influence ride comfort and road feedback; lower profiles favor sharper handling but may reduce ride smoothness. Overall, these configurations optimize balance between sporty driving and daily usability.

Compared to its predecessor, the BMW M3 (F80), the G80 generation is slightly larger and heavier. The G80 measures approximately 4795 mm in length (4,718 mm for F80), with a width of up to 1918 mm (across mirrors wider than F80's 1,855 mm), and a marginally increased height. The curb weight has also increased, reflecting added technology and safety features. Performance-wise, the G80 features a more powerful engine, improved suspension, and advanced driving aids, resulting in sharper handling and quicker acceleration. The dimensional growth offers more interior space and refinement but maintains the aggressive, sporty character that defines the M3 lineage.

The BMW M3 (G80)'s size aligns closely with other high-performance sedans such as the Mercedes-AMG C63 and Audi RS5 Sportback. Its length of about 4795 mm (188.8 inches) places it slightly on the larger side compared to the AMG C63, which is approximately 4764 mm (187.5 inches) long, and similar to the Audi RS5. The width with mirrors extended (2068 mm or 81.4 inches) is broader than many competitors, enhancing road presence but requiring more parking space. The M3's luggage capacity of 480 liters is competitive, often exceeding that of rivals. This balance of size and practicality positions the M3 as a standout choice for those valuing both performance and everyday usability.

The BMW M3 (G80) has a roof load capacity of 75 kg (approximately 165 lbs). This rating allows owners to safely mount roof racks, cargo boxes, or bike carriers without risking damage to the roof structure or impacting driving safety. This feature broadens the M3's practicality, enabling the transport of additional cargo like skis, luggage, or outdoor equipment, which is particularly useful for trips or active lifestyles. When using roof attachments, it's important to adhere to weight limits and ensure proper installation to maintain vehicle stability and aerodynamic performance.

With a height between 1433 and 1438 mm (56.4 to 56.6 inches) and a width ranging from 1903 to 1918 mm (74.9 to 75.5 inches), the BMW M3 (G80) provides a comfortable cabin environment balanced for sporty driving and passenger space. The relatively wide stance enhances shoulder room, allowing passengers a less cramped seating experience, while the modest height helps maintain a low center of gravity for better vehicle dynamics. The interior layout effectively uses the space to provide ergonomic seating and sufficient headroom for most adults, contributing to long-distance comfort without sacrificing the aggressive, driver-focused feel characteristic of the M3 series.
