Innovations include a windscreen and forward portion of roof integrated into one seamless glass surface.
Behind that is a two-piece glass panel, half of which pivots by electric motor to act as an aerodynamic spoiler, vent air from the cabin and increase rear passenger headroom.
Inside the Kabura replaces the traditional 2+2 seating layout of sports coupes with a clever 3+1 arrangement that results in greater passenger comfort without increasing weight or size.
While a standard left-side door provides access to the driver cockpit and a rear jump seat, the right side of the car is purposely asymmetrical with an extra rear-hinging door.
The right-side door arrangement - similar to that of the RX-8 production model - provides access to two full-sized passenger seats.
Mazda has removed the glove box, minimised the instrument panel and moved the front seat forward, allowing space for a rear passenger to enjoy approximately the same leg, shoulder and headroom as the front occupant.
