Seating Configuration and Passenger Accommodation

The 6 Series lineup encompasses three distinct body styles, each offering different seating arrangements suited to specific usage patterns.

Two-Door Coupe and Convertible Models

The traditional coupe and soft-top convertible configurations feature cramped rear seating intended primarily for children rather than adults. The sloping roofline further restricts headroom for rear passengers, making these models best suited for two-occupant primary use. The convertible variant includes a unique glass rear window that lowers independently, providing ventilation with the soft top raised or serving as a wind deflector when fully lowered.

Gran Coupe Four-Door Configuration

The Gran Coupe body style introduces four-door convenience with pillarless frameless windows that contribute to the elegant aesthetic. This configuration provides more practical rear seat access for adults while maintaining the coupe’s stylish profile. Seating comfort for longer journeys benefits from supportive cushioning and adjustable positioning throughout the range.

Storage Considerations

The cabin exhibits limited storage capacity, with front storage confined to covered cup holders and a long but shallow center console. Door pockets provide minimal storage depth, requiring passengers to carefully arrange personal items. The trunk accommodates 13.0 cubic feet of cargo with all rear seats in place, adequate for typical luggage and travel requirements.
