the mitsubishi battery power sub compacts hits u.s. show rooms next year, one of a growing number of electric vehicles headed our way to manufactures. the i-mi is based on the conventional car called the i and uses an internal comustion engine. it looks cool because it does. did i mention it's already on sale in japan? the motor in the i-mi isn't powerful, but the car is light and goes through with little effort. and a complete opposite what you're used to in a small car, the engine revving mildly and gears shifting to keep up with the flow of traffic. nothing odd about the interior, has cup holdings and a glove compartment and the rest of the world has a thing or two looking out for the rest of the car. it's actually smaller than a mini cooper, there's plenty of room for four passengers, and u.s. versions will be slightly larger on the outside for safety standards and interior upgrades to justify a price of $30,000. and this will be over there, as will i. running on skinny little tires, it's a nearly silent motor. pretty quiet even if
