2025 BMW M4 Convertible (G83 LCI, facelift 2024) Dimensions, Size & Specs

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.
