World's Smallest Cars

Toyota's (ticker: TM) iQ, which measures just 2.985 meters (117 inches) long by 1.68 meters (65 inches) wide, seats three adults and one small child by taking advantage of some pretty nifty design innovations, such as a flat fuel tank under the floor and a new smaller, but not less effective, air conditioning unit from Denso. It's economical, too. Under the Japanese 10-15 test cycle, the iQ gets 54 mpg, while CO2 emissions from its one liter gasoline engine are among the lowest in the Toyota stable, including hybrids. Prices range from $15,220 (1.4 million yen) to $17,390 (1.6 million yen).
