Created as a sporty, every day car, the Mazda 2-based Kusabi concept is proof that fun, practical, and affordable aren't mutually exclusive. The four-seat Kusabi is powered by a 1.6-liter common-rail diesel engine with a six-speed transmission -- a reminder that fun in this segment is based heavily on style and dynamics, rather than power. Its show-car trick is a clever Twin-Lift hatchback that allows the rear to lift traditionally and to also hinge in the middle in a gullwing fashion. Access to the second-row seats is equally innovative, with the front buck seat backs swinging inward, rather than folding forward. Mazda sees growth potential in this sport compact segment for Europe and Japan. No doubt, the product planners will be watch the success of small hatches, like the Mini and Ford Focus ZX3, to gauge the worldwide potential.
