Ford Fiesta Econetic Diesel Offers Lower Fuel Consumption than Prius in Australian Combined Cycle Testing; Prius Still Offers Lowest CO2
Australia’s GoAuto notes that the new Ford Fiesta Econetic diesel (earlier post), with fuel consumption of 3.7 L/100km (63.6 mpg US) under the Australian combined fuel test cycle, offers lower fuel consumption than the third-generation Prius, with 3.9 L/100km (60 mpg US) under the same test cycle.
However, the gasoline-fueled Prius still comes out with the lowest CO2 emissions of any car on the Australian market at 89 g/km, due to the differences in gasoline and diesel fuels. More specifically, according to the Australian government’s GreenVehicleGuide:
|Ford Fiesta Econetic and Toyota Prius|
|Vehicle||Fuel||Fuel consumption (L/100km)||CO2||Air pollution*|
|* The air pollution rating is based on a scale from 1 to 10, with 10 being the lowest.|
Australian vehicle emission standards and fuel cycle testing (Australian Design Rules, ADRs) largely reflect international standards developed by the United Nations. These standards are adopted in Europe and many other countries around the world, and are known as the Euro standards.
An updated ADR, ADR81/02 Fuel Consumption Labelling for Light Vehicles, came into effect from October 2008 for vehicle models sold in the Australian market for the first time and from April 2009 for all new vehicles sold in the Australian market.
