Dimensions

The exact kerb weight and luggage volume can vary with wheel, tyre, option-pack and equipment selection. The folding acoustic fabric roof is substantially lighter and more compact than the previous-generation folding hardtop arrangement, while retaining four-seat usability.

Available Colours

Frozen matte finishes require specialist care because abrasive polishing, conventional automatic-car-wash processes and localised paint correction can permanently alter the surface appearance. Availability of individual special-order colours may depend on production capacity and the selected vehicle configuration.

Wheel and Tyre Options

The staggered wheel and tyre arrangement supports the M4 Convertible’s rear-biased M xDrive handling balance. Wheel selection can affect ride comfort, kerb weight, fuel consumption, emissions and luggage-space practicality.

Soft-Top Acoustic Convertible Roof

• Fully electric acoustic fabric roof with a multi-layer construction designed to improve thermal and acoustic insulation.
• Opens or closes in approximately 18 seconds.
• Can be operated at speeds of up to 31 mph (50 km/h).
• Roof operation is controlled through the centre display and dedicated vehicle controls.
• The roof folds into a compact rear-deck compartment, preserving more luggage capacity than the previous folding hardtop design.
• Roof mechanism includes automatic tensioning and sealing systems for weather resistance and reduced wind noise.
• Rear-glass window is integrated into the acoustic fabric roof.
• Roof can be operated remotely using supported vehicle controls, subject to the UK equipment configuration.
• Roof colour is coordinated with the exterior and interior specification; black acoustic fabric is the principal M4 configuration.
