The Tokyo Motor Show is one of our favorites, mainly because of all the wacky and wild concept vehicles on display. This year was no exception, and Nissan did their part to add to the concept car fun.

PIVO2

Getting the most attention on the Nissan stand, aside from the GT-R, was the PIVO2 concept. A follow-up to the popular PIVO shown here two years ago, the PIVO2 is basically a spherical passenger cabin on a four-wheeled platform. The wheels can be turned in any direction and the passenger compartment itself can spin 360 degrees.

Each wheel is fitted with an electric motor with power coming from advanced lithium-ion batteries. Not only is PIVO2 friendly to the environment, it also takes care of its driver. A "Robotic Agent" is fitted into the dashboard that recognizes the facial images of the driver, providing not only useful information for vehicle operation, but also "speaks to you to cheer you up or to soothe you accordingly."

Round Box

A little more mainstream (just a little) is the R.D/B.X, or Round Box. With a shape resembling a duck's bill, the two-door, four-seat compact car provides open-air motoring via a removable tri-partition roof that can be stored in the boot.

The Round Box is designed for passengers to communicate well with each other via a special display that can send information to any of the seating positions. Continuing with the eco-friendly theme, power comes from a direct-injection petrol engine with a turbocharger and Extronic CVT.

Intima

A futuristic view of a luxury saloon, at first glance the Intima doesn't look all that outlandish. But then you notice that the windscreen carries into the roof as one piece, providing an open-air feeling inside. Then you open the doors and the front and back open opposite and 180 degrees, providing an incredibly large opening for easy entry and exit to both front and rear seats. Further assisting with entry is the swiveling front seats, that make it possible to just sit down and rotate into the car.

The inside is luxurious but definitely in concept form, with extensive use of wood, chrome and other quality materials and uniquely shaped individual seats. Soft blue lighting can be found throughout the interior, adding to the upscale appearance. A clean V6 diesel rounds out this environmentally friendly vehicle.

NV200

Designed as a work van of the future, the NV200 doesn't look all that unusual in it’s standard configuration until you notice the "Attention: Pod Opens" stencil on the side panel. This pod is designed to be configured to whatever commercial or personal need necessary and it extends out the back of the vehicle for easy access to tools, equipment, or whatever else needs to be stored.

The NV200 example on display featured all the gear one might need for underwater exploration and photography. While the design is definitely not ready for production, the idea of a storage system such as this is not difficult to imagine going into production.
