Subaru's Exiga is a minivan concept that will go into production eventually. Subaru specifies a boxer-style engine and all-wheel-drive, two elements that the company knows how to build. Video screens abound in the cabin, even in place of the rear-view mirror, which would use a camera to show what's behind the Exiga.

Honda felt like it had such a successful launch with the Honda Fit last year, that it already designed a new one. The new Fit looks a tad bit larger, but it represents an evolutionary rather than revolutionary change.

Mazda goes high-concept with the Taiki. This flivver features a really extreme design, intended to explore Mazda's Zoom-zoom concept. It would be a rear-wheel-drive car with an engine in the front.

This new minivan concept could enter production in 2008. It features luxurious middle- and third-row seats that recline and have ottomans. These seats also each get a video monitor mounted on the head rest in front, making it a fine line between personal jet and minivan.

The greenhouse on the RiN is actually green, as befits the idea behind the car. It is supposed to promote the health and well-being of its occupants through posture correcting seats and a mood-meter on the steering wheel. If the car detects tension, it will try to calm down the driver.

RD/BX stands for round box, in Nissan nomenclature, and this concept embraces that oxymoronic phrase. The interior is designed to let its occupants interact freely, with plenty of openness between the front and back seats. The instrument cluster is pure concept car, with luminescent displays and LCDs.

Possibly the next-generation Galant, the Concept-ZT sports a luxury look we wouldn't have expected from Mitsubishi. Beyond its elegant exterior and interior, it runs off a clean diesel engine mated to a twin-clutch transmission.

Honda makes an environmentally conscious design with the CR-Z. The little sports car, which borrows styling from the past CR-X, uses a hybrid powertrain. Interior elements come from the current generation of the Civic. Honda is committed to building some form of this little sports car in 2009.

The Hi-CT looks like a Scion xB for tall people. With a freight truck design, it's not pretty, but it does employ the usual concept-car features, such as a yoke-style steering wheel, lots of panels on the instrument cluster, and a white interior. The rear external deck can be used to store sports gear.
