The P-NUT
http://automobiles.honda.com/p-nut/ is one of those concept vehicles we expect will never be produced for the public. It's an ultra-compact car with a center driving seat, and two rear seats, for an odd-ball three seat configuration. The modular rear engine bay has been left open so they can experiment with various drive train technologies including including a conventional small displacement internal-combustion engine, a hybrid gasoline-electric powertrain, or a battery-electric powertrain.
