The car measures 4801 mm (189.0 inches) in length, offering a balanced footprint that combines road presence with maneuverability. Its width stands at 1887 mm (74.3 inches) with standard mirrors, expanding to 2081 mm (81.9 inches) when the mirrors are opened, accommodating the needs for aerodynamic efficiency and visibility. The height is relatively low at 1399 mm (55.1 inches), emphasizing the car's sporty coupe-like profile despite being a convertible. These dimensions contribute to its aggressive stance and open-top appeal, ensuring both a thrilling driving experience and practical road presence.

The width of the BMW M4 Convertible (G83 LCI) is 1887 mm (74.3 inches) with the mirrors folded in, which is practical for tight parking spaces and urban driving. When the exterior mirrors are opened, the width increases to 2081 mm (81.9 inches). This widened stance is crucial for providing the driver with optimal rear visibility and safety during driving. The mirrors, designed for aerodynamic efficiency and minimal wind noise, create just under a 200 mm (7.6 inches) increase in total width. Drivers should be mindful of this expanded width in narrow spaces.

The 2025 BMW M4 Convertible (G83 LCI) has a curb weight of approximately 1925 kg (4244 lbs). This weight reflects the vehicle as it is typically equipped and ready to drive, including fluids and a full tank of fuel but without passengers or cargo. The maximum permissible weight, which includes passengers and cargo, is 2345 kg (5171 lbs). This difference allows for a payload capacity of roughly 420 kg (926 lbs). The weight balance, along with advanced construction materials and chassis tuning, plays a crucial role in the M4 Convertible's dynamic handling and performance on both road and track.

The BMW M4 Convertible (G83 LCI) offers a luggage capacity of 385 liters (approximately 13.6 cubic feet), which is quite generous for a convertible. This generous trunk space allows for the storage of multiple suitcases, shopping bags, or weekend gear, making it practical for everyday use despite its sporty design. The capacity is achieved through efficient packaging and space optimization, including a design that accommodates the convertible roof mechanism without sacrificing trunk volume. This makes the M4 Convertible a versatile choice for drivers who seek spirited driving along with usable cargo space.

The ride height, also known as ground clearance, of the BMW M4 Convertible (G83 LCI) is 121 mm (4.8 inches). This relatively low clearance emphasizes the car’s sporty character and aerodynamic focus, contributing to excellent handling and stability in corners. However, the low ground clearance means drivers should be cautious over speed bumps, steep driveways, and uneven road surfaces to avoid underbody contact. This setup enhances road feel and performance but requires attentiveness in everyday urban or uneven road conditions.

The BMW M4 Convertible (G83 LCI) is equipped with staggered rim and tire sizes to optimize performance and handling. The front rims measure 9.5J x 19 inches, paired with 275/35 R19 tires, while the rear rims are wider at 10.5J x 20 inches, fitted with 285/30 R20 tires. This staggered setup enhances traction and stability by balancing front grip with wider rear contact patches, which is essential given the car’s powerful rear-wheel-drive dynamics or optional all-wheel drive. These sizes contribute to the car's aggressive stance and provide excellent road holding in various driving conditions.

Yes, the BMW M4 Convertible (G83 LCI) fits into a standard home garage as its dimensions are within typical garage space limits. With a length of 4801 mm (189.0 inches) and a width of 1887 mm (74.3 inches) (2081 mm or 81.9 inches with mirrors open), it fits comfortably in most residential garages, which typically range around 2.4 to 3 meters (7.9 to 9.8 feet) in width and 5.5 to 6 meters (18 to 20 feet) in length. When parking, the mirrors can be folded to reduce width for easier access. The car’s height of 1399 mm (55.1 inches) also poses no issue for standard garage door clearances, making it suitable for daily use and protection indoors.

Compared to its predecessor, the earlier BMW M4 Convertible (F83 generation), the 2025 M4 Convertible (G83 LCI) shows refined dimensions and updated design cues. The G83's length at 4801 mm (189.0 inches) and width of 1887 mm (74.3 inches) mark a modest increase in size, offering enhanced interior space and road presence. The G83 facelift brings sharper styling with updated headlights, refined aerodynamic elements, and a more modern, aggressive stance compared to the F83. There are also improvements in chassis dynamics and weight distribution, even though the curb weight increased slightly due to added features and structural reinforcements, reflecting advancements in safety and performance technology.

The BMW M4 Convertible (G83 LCI) holds competitive dimensions in the high-performance convertible segment. Its length of 4801 mm (189.0 inches) and width of 1887 mm (74.3 inches) position it close to rivals like the Audi RS5 Convertible and the Mercedes-AMG C63 Cabriolet. While the M4 offers a slightly lower ride height of 121 mm (4.8 inches), which improves handling dynamics, its luggage capacity of 385 liters (13.6 cubic feet) is usually larger than many competitors, adding practicality. The staggered rim and tire sizes further emphasize its sporty intent, balancing elegance and aggressive performance more effectively in its class.

The BMW M4 Convertible (G83 LCI) facelift for 2025 stands out within the M4 range by combining open-top driving exhilaration with cutting-edge technology and performance enhancements. Maintaining the M4’s reputation for sharp handling, the G83 features new styling updates including a fresh front fascia, lighting elements, and updated aerodynamic components, all while preserving the 4801 mm (189.0 inches) length and 1887 mm (74.3 inches) width that provide a purposeful stance.
