In a land conspicuously devoid of space-consuming sport/utilities, tiny transporters reign supreme and the ultimate measure of compact efficiency is fuel economy. Enter Daihatsu's aluminum-and-resin-bodied follow-up to the UFE seen at the 2001 Tokyo show, the UFE-II. This latest show machine weighs in at just 1254 pounds and boasts a stunning 0.19 coefficient of aerodynamic drag, key factors in this effort to obliterate the triple-digit fuel economy barrier. Narrow, large-diameter tires slash rolling resistance, while a 660-cc direct-injection gasoline engine is meshed to two electric motors and a nickel-metal hydride battery to achieve the world's highest fuel economy, according to Daihatsu, at more than 140 mpg. Gullwing doors allow access to the inside, though it appears only small children could ride in the Lilliputian backseat.
