When pivoted-up by an electric motor, it acts as a roof spoiler, which also vents air from the interior and increases rear passenger headroom. A photovoltaic solar cell in the panel helps to control interior temperature, as well as helping recharge the battery for powering accessories. The larger glass hatch panel has side-mounted hinges to provide access to the Kabura's cargo compartment. Interior The unique 3+1 interior layout is designed to provide comfortable seating for one or two tandem passengers to the right of the driver, with only occasional use of the fourth "jump-seat" behind the driver as needed. The driver's door provides access to the driver's cockpit, and to the rear jump seat. The other side of the car is a purposely asymmetrical arrangement. Eliminating the glovebox and minimizing the instrument panel allows shifting the front passenger about six-inches ahead of the driver's seating position. In turn, the second inside passenger, sitting in tandem behind the inside passenger, has approximately the same leg, shoulder, and headroom as the front passenger. The Kabura includes a secondary passenger-side door, allowing easier access to the seat behind the front passenger. After the front door is opened, touching a button slides the rear door straight back into a cavity notched into the rear-quarter panel area, instead of swinging on hinges. Kabura's concept interior is produced from regenerated leather substrate, mostly from post-industrial waste recovered from the manufacturing of Nike brand athletic shoes.

Slotting in as an entry-level alternative to the RX-8 2+2, the Kabura was said to borrow significant mechanical components from the MX-5 roadster while having a similar shape to the MX-3. Although it never entered production, the 2011 RX-8 refresh drew inspiration from the Kabura.
