2010 Toyota Prius – Click above for high-res image gallery

We already knew the 2010 Toyota Prius would put up some impressive fuel economy numbers but the official Japanese numbers are just insane. On the standard 10-15 test cycle, the new Prius is rated at 89.4 mpg (U.S.) with CO2 emissions of just 61 g/km! While the new Prius is certainly efficient, these numbers certainly seem highly unrealistic. It's likely that Toyota has calibrated the Japan market model to specifically get the maximum out of this low speed urban drive cycle (average speed 16 mph) and most drivers are unlikely to come anywhere near those numbers. Dedicated hypermilers, of course, can top 90 mpg, but that takes way too much effort. On the newer JC08 test cycle, the numbers drop a bit to a mere 76.7 mpg (U.S.). Here in the U.S. the Prius is rated at 50 mpg combined.

New Japan-market 'Prius' Gets World's Best Fuel Efficiency

Tokyo - TOYOTA MOTOR CORPORATION (TMC) announces that the Japanese-market version its third-generation ''Prius'' gasoline-electric hybrid vehicle has achieved the best fuel efficiency in the world1 for a mass-produced vehicle, as measured using the 10-15 test cycle of the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT). 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 38.0km/l (CO2 emissions: 61g/km), thus exceeding by more than 25 lower than the 2005 standards under the MLIT's approval system for low-emission vehicles, which is currently the strictest standard in Japan for emissions. As such, under the Japanese government's taxation system for environmentally friendly vehicles, the new Prius is exempt from the automobile weight tax (until April 30, 2012), is exempt from the automobile acquisition tax (until March 31, 2012) and qualifies for a 50% reduction in the automobile tax (until March 31, 2010).
