Minicars haven't been at all significant or successful in the U.S. market, yet several carmakers think that there is a future for this size car in American cities and urban centers. At about 14 inches shorter than the Chevrolet Sonic subcompact (in hatchback form), the Spark measures up as longer than a Smart Fortwo or Fiat 500, or about the same length as a base Mini Cooper. Fuel economy should be excellent (especially in city driving), parking and maneuverability will be even easier than in nearly any other vehicle and yet the Spark's four seats should give it more flexibility versus some other minicars.
