The UFE-III is a third-generation, 660-cc super streamliner concept that follows the UFE (from the 2001 Tokyo Motor Show) and the UFE-II (from the 2003 show). The 2005 UFE-III (for Ultra Fuel Economy) is now a three-seat car with a centrally located driving position and a big, lift-up canopy door. Its coefficient of drag has improved from an already impressive 0.19 to an incredible 0.17. The UFE-III, which is only 134 inches long, has a 660-cc, three-cylinder hybrid powertrain that is basically a carryover from the 2003 concept. Fuel economy is now up to 72 kilometers per liter--or an incredible 203 mpg--compared with 60 km/l (169 mpg) two years ago.
