In Japan, Prius is the FE king

Tokyo, Japan ? Toyota announced that the Japanese-market version the 2010 Toyota Prius-III has been certified as the best most fuel efficient mass-produced vehicle in the world as measured using the Japanese peculiar 10-15 test cycle. The achievement represents part of TMC's numerous and ongoing efforts to improve fuel efficiency through advanced vehicle development. The new Prius, scheduled for launch in Japan in mid-May, has a fuel efficiency of 89.4 mpgUS with CO2 emissions of just 61g/km, thus exceeding the upcoming 2010 Japanese emissions standards by over 25%. Under the Japanese new and supposedly more realistic JC08 test cycle, the Prius-III achieved 76.7 mpgUS and CO2 emissions of 71g/km, thus meeting the way out 2015 national mandates.
