The low height also can affect headroom, but BMW designs their interiors to maintain comfort. Additionally, the low profile can be advantageous for fitting into height-restricted parking garages.

The BMW 8 Series Convertible (G14) has a curb weight ranging between 1830 kg and 2050 kg (approximately 4037 to 4519 lbs), depending on the configuration and optional equipment.

The ride height or ground clearance of the BMW 8 Series Convertible (G14) falls between 118 mm to 125 mm (roughly 4.6 to 4.9 inches). This low ground clearance favors sporty performance and handling on smooth roads by lowering the center of gravity. However, it limits the ability to traverse rough or uneven terrain, and drivers need to be cautious on speed bumps or steep driveways.

Yes, the BMW 8 Series Convertible (G14) fits into a standard residential garage, but with some considerations. Its width with mirrors opened is 2137 mm (about 84.1 inches), which requires garage spaces to be wide enough for easy entry without mirror damage. The length of approximately 4850 mm (190.9 inches) and height up to 1345 mm (53 inches) are within typical garage size ranges. Drivers should verify their specific garage dimensions, including clearance and door widths, to ensure a seamless fit.
